Answer 1

According to given information, the solution to the given system of equations is (x, y) = (-1, -8).

What is equation?

In mathematics, an equation is a statement that two expressions are equal. It consists of two sides, a left-hand side and a right-hand side, separated by an equal sign (=).

A system of equations is a collection of two or more equations involving the same variables. The goal of solving a system of equations is to find the values of the variables that satisfy all the equations in the system simultaneously.

According to given information,

The given equations are:

y = 3x − 5

y = 10x + 2

To solve for x and y, we can equate the two expressions for y:

3x − 5 = 10x + 2

Simplifying this equation, we get:

3x - 10x = 2 + 5

-7x = 7

x = -1

Substituting the value of x in either of the original equations, we get:

y = 3(-1) - 5 = -8

or

y = 10(-1) + 2 = -8

Therefore, the solution to the given system of equations is (x, y) = (-1, -8).

Answer 2

The solution to the system of equations is x = -1 and y = -8, written as the ordered pair (-1,-8).

What is an equation?

The equation is the mathematical statement showing that two mathematical expressions are equal. The equations have variables and the objective of solving an equation is to find the value of those variables.

To solve the system of equations:

Y = 3x − 5

Y = 10x + 2

This equation can be solved by substitution or elimination methods.

Using substitution method:

From the first equation,

Y = 3x - 5.

Substitute this value of Y into the second equation to get:

3x - 5 = 10x + 2

Simplifying and solving for x:

`7x = -7

x = -1

Substitute this value of x back into either of the original equations to get:

Y = 3(-1) - 5 = -8

Therefore, the solution to the system of equations is x = -1 and y = -8, written as the ordered pair (-1,-8).

A histogram of the average age for every possible combination of cases from the population is referred to as a scatter plot

A scatter plot matrix is a plot that presents all feasible scatter plots for a given collection of variables in a matrix structure. It is helpful for investigating the connections between related factors in a collection. A scatter plot matrix is not a histogram that shows the average age for every mix of instances drawn from the community.

Instead, it is referred to as a sampling distribution or a distribution of sample means. This kind of histogram displays the range of means for all conceivable community samples of a specific number. It is a crucial idea in statistics because it aids in understanding a population's characteristics based on a subset of data.

The value of a brand new car is $10,000 and the value depreciates 18% every year. Write a function to represent the value of the car after t years, where the quarterly rate of change can be found from a constant in the function. Round all coefficients in the function to four decimal places. Also, determine the percentage rate of change per quarter, to the nearest hundredth of a percent.

Answers

The function representing the car's value after t years is V(t) = [tex]$10,000 \times (1 - 0.4231)^4t[/tex]. The percentage rate of change per quarter is approximately 57.69%.

What is a function?

[tex]V(t) = $10,000 \times 0.2835^t[/tex]

To represent the value of the car after t years, we can use the following formula:

V(t) = V(0)  x (1 - r)⁴t

where V(0) is the car's initial value ($10,000), r is the quarterly rate of change, and t is the number of years.

To find the quarterly rate of change, we can use the annual rate of change of 18%:

r = (1 - 0.18)^(1/4)

r ≈ 0.4231

Therefore, the function to represent the value of the car after t years is:

[tex]V(t) = $10,000 \times (1 - 0.4231)^4t\\V(t) = $10,000 \times 0.2835^t[/tex]

To determine the percentage rate of change per quarter, we can use the formula:

q = (1 - r) x 100%

q = 57.69%

Therefore, the percentage rate of change per quarter is approximately 57.69%.

The growth rate of Covid patient is 5% per hour. If the number of Covid patient in the morning 8:00 am is 44,100, what was the number before 2 hours?

Answers

Rounding to the nearest whole number, the previous number of Covid patients before 2 hours was 39,991.

What is growth rate?

A population's growth rate gauges how much a quantity's worth has increased in percentage terms.

To find the number of Covid patients before 2 hours, we need to apply the 5% growth rate for 2 hours to the current number of patients (44,100 at 8:00 am).

First, we can find the growth factor by adding 1 to the percentage growth rate expressed as a decimal:

1 + 0.05 = 1.05

Next, we can raise the growth factor to the power of the number of hours of growth:

1.05² = 1.1025

Finally, we can divide the current number of patients by the growth factor to find the previous number of patients:

44,100 / 1.1025 = 39,990.91

Rounding to the nearest whole number, the previous number of Covid patients before 2 hours was 39,991.

b) Probability of sum of an even numbers = 1/2.

c) Probability of getting a 2 on at least one dice = 11/36.

a) The ratio of good outcomes to all possible outcomes of an event is known as the probability. The number of positive results for an experiment with 'n' outcomes can be represented by the symbol x. The probability of an occurrence may be calculated using the following formula.

Probability(Event) = Positive Results/Total Results = x/n

Experiment: A trial or procedure carried out to generate a result is referred to as an experiment.

Sample Space: A sample space is the collection of all potential results of an experiment. Tossing a coin, for instance, has two possible outcomes: head or tail.

Favorable Consequence: An occurrence is deemed to have generated the desired outcome or an anticipated event if it did so.

Trial: To conduct a trial is to conduct a random experiment.

It is given to us that a die is rolled

Then, the sample space = {1,2,3,4,5,6}

We are given that it is an even number.

The, we have left with reduced sample space is {2,4,6}

Thus, the probability of 6 is 1/3.

b) So, the number of possibilities of the sum of even numbers is 18.

The probability of an event = number of favorable outcomes/ total number of outcomes.

Probability of sum of an even numbers = 18 / 36 = 1 / 2.

c) Probability of getting a 2 on at least one dice = Favorable outcomes / Total outcomes = 11 / 36 So, P (getting 2 at least on 1 dice) = 11/36.

Answers

The area of the shaded square is 4 square centimeters, and the radius of the circle is approximately 1.41 cm.

To find the area of the shaded square and the radius of the circle, we will follow these steps:
Step 1: Identify the dimensions of the square.
From the student question, we know that the square has sides of 2 cm each.
Step 2: Find the area of the square.
The area of a square can be calculated using the formula:

Area = side × side.
In this case, the area of the square is:

2 cm × 2 cm = 4 square centimeters.
Step 3: Find the diagonal of the square.
The diagonal of a square can be found using the Pythagorean theorem:

diagonal² = side² + side².
In this case, the diagonal² = 2 cm² + 2 cm² = 4 cm² + 4 cm² = 8 cm².
Taking the square root of both sides, we get: diagonal = √8 cm ≈ 2.83 cm.
Step 4: Find the radius of the circle.
Since the circle is inscribed in the square, its diameter is equal to the diagonal of the square.

Thus, the radius of the circle is half the diagonal.
Radius = diagonal ÷ 2 ≈ 2.83 cm ÷ 2 ≈ 1.41 cm.

What is the diameter of a circle to the nearest hundredth with the given
circumference of 40?

Answers

Answer:

12.74

Step-by-step explanation:

To find the diameter of a circle with a given circumference, you can use the formula:

Circumference = π x diameter

where π (pi) is a mathematical constant approximately equal to 3.14159.

In this case, the circumference is given as 40. So we can rearrange the formula to solve for the diameter:

diameter = Circumference / π

Substituting the given values, we get:

diameter = 40 / π

To get the answer to the nearest hundredth, we can use a calculator or estimate π to a few decimal places. Let's use π ≈ 3.14.

diameter = 40 / 3.14

diameter ≈ 12.74

Therefore, the diameter of the circle to the nearest hundredth is approximately 12.74.

Step-by-step explanation:

Circumference = pi  * d

circumference / pi = d  =  40 / pi = 12.73 units

Find the polynomial function h(x)of lowest degree in standard form if it has roots: x=-5,√3

Answers

Step-by-step explanation:

If a polynomial function has roots at x=-5 and x=√3, it means that it can be factored as follows:

h(x) = a(x+5)(x-√3)

where 'a' is a constant coefficient that represents the leading term of the polynomial function.

To find the value of 'a' and express the polynomial function in standard form, we can multiply the factors and simplify as follows:

h(x) = a(x+5)(x-√3)

h(x) = a(x^2 - √3x + 5x - 5√3)

h(x) = a(x^2 + 2x√3 - 5√3)

To find the value of 'a', we can substitute one of the given roots into the equation and solve for 'a'. Let's choose x = -5:

h(-5) = a((-5)^2 + 2(-5)√3 - 5√3)

h(-5) = a(25 - 10√3 - 5√3)

Since x=-5 is a root, h(-5) = 0. Therefore:

0 = a(25 - 15√3)

a = 0 or a = (15√3)/25 = (3√3)/5

Since the coefficient 'a' cannot be zero, the polynomial function h(x) of lowest degree in standard form is:

h(x) = (3√3/5)(x^2 + 2x√3 - 5√3)

h(x) = (3√3/5)x^2 + (6/5)√3x - 3√3

Un juego tiene una baraja de cartas con 10 cartas rojas, 4 cartas azules y 2 cartas amarillas. ¿Cuál es la probabilidad de sacar dos cartas rojas sin reemplazo?​

Answers

Answer:

Step-by-step explanation:

(-3,4)

Answer:

La probabilidad de sacar dos cartas rojas sin reemplazo de una baraja con 10 cartas rojas, 4 cartas azules y 2 cartas amarillas es 3/8 o 0.375.

Step-by-step explanation:

1. Determina la probabilidad de sacar una carta roja del mazo:

P(Rojo) = Número de Tarjetas Rojas / Número Total de Tarjetas

P(Rojo) = 10 / (10 + 4 + 2)

P(Rojo) = 10 / 16

P(Rojo) = 5 / 8

2. Determine la probabilidad de sacar una segunda tarjeta roja después de sacar la primera carta. Como ya se sacó una carta roja, solo quedan 9 cartas rojas en el mazo, y el número total de cartas restantes es 15:

P(Roja en el segundo sorteo) = Número de tarjetas rojas restantes / Total de tarjetas restantes

P (Rojo en el segundo sorteo) = 9 / 15

3. Multiplique la probabilidad de sacar una tarjeta roja por la probabilidad de sacar una segunda tarjeta roja después de sacar la primera para obtener la probabilidad de sacar dos tarjetas rojas sin reemplazo:

P(Dos tarjetas rojas) = ​​P(Roja) * P(Roja en el segundo sorteo | Roja en el primer sorteo)

P(Dos tarjetas rojas) = ​​(5/8) * (9/15)

P(Dos tarjetas rojas) = ​​3/8 o 0,375

Por lo tanto, la probabilidad de sacar dos cartas rojas sin reemplazo del mazo es 3/8 o 0.375.

Answers

t-value (-4.38) is greater than the absolute value of

the critical t-value (1.990), we can reject the null hypothesis and conclude

that there is convincing evidence that the mean reading level for health-

related pages differs for Wikipedia and WebMD.

To test if there is convincing evidence that the mean reading level for

health-related pages differs for Wikipedia and WebMD, we can use a

two-sample t-test.

Let's set up the null and alternative hypotheses:

Null hypothesis: The mean reading level for health-related pages is the

same for Wikipedia and WebMD (μ1 = μ2)

Alternative hypothesis: The mean reading level for health-related pages

differs for Wikipedia and WebMD (μ1 ≠ μ2)

We will use a significance level of 0.05, which means that we are willing

to accept a 5% chance of making a Type I error (rejecting the null

hypothesis when it is actually true).

We can use the following formula to calculate the test statistic:

t = (x_1 - x_2) / (s_pool × √(2/n))

Where:

x_1 and x_2 are the sample means

s_pool is the pooled standard deviation, calculated as:

[tex]\sqrt{ (((n1-1)\timess1^2 + (n2-1)\timess2^2) / (n1+n2-2))}[/tex]

n is the sample size for each group

Plugging in the values, we get:

x1 = 26.2

x2 = 43.6

s1 = 14.2

s2 = 19.9

n1 = n2 = 40

s_pool = [tex]\sqrt{(((40-1)\times14.2^2 + (40-1)\times19.9^2) / (40+40-2))} = 17.0[/tex]

t = (26.2 - 43.6) / (17.0 × √(2/40)) = -4.38 (rounded to two decimal places)

Looking up the critical t-value with degrees of freedom = 78 (df = n1 + n2 - 2), and a significance level of 0.05, we get:

t_critical = ±1.990

Since our calculated t-value (-4.38) is greater than the absolute value of

the critical t-value (1.990), we can reject the null hypothesis and conclude

that there is convincing evidence that the mean reading level for health-

related pages differs for Wikipedia and WebMD.

A survey of American households asked 1000 Americans and found that 20% of them own 2 pets identify the population

A. All Americans
B. 20%
C. 1000
D. 2

Answers

The sample size was 1000 Americans, and 20% of the survey respondents reported owning 2 pets. To calculate the number of Americans who own 2 pets, we can use the formula (20/100) x 1000 = 0.20 x 1000 = 200. However, we cannot directly conclude that 20% of all Americans own 2 pets.

How will you identify the sample?

The 1000 Americans that were polled in this case make up the sample. This indicates that a sample rather than the complete American population was used to get the data on pet ownership.

A statistic, which is a quantitative description of the sample, is the finding that 20% of survey respondents reported having two pets. It is crucial to remember that while this statistic provides useful information about the sample, it cannot be used to draw conclusions about the full population without additional research or inference.

Based on the poll, we can apply the following calculation to get the proportion of Americans who own two pets:

Number of Americans who own 2 pets = (Percent of survey respondents who own 2 pets / 100) x Sample size

Plugging in the given values, we get:

Number of Americans who own 2 pets = (20 / 100) x 1000

= 0.20 x 1000

As a result, we may assume that 200 Americans possess 2 pets based on the poll results. However, as this would entail assuming the representativeness of the sample and the generalizability of the results, we cannot immediately conclude that 20% of all Americans own 2 pets.

it is fair to say that the ucr is: group of answer choices a mutually exclusive measure not a truly reliable measure an exhaustive measure all of the above

Answers

The UCR (Uniform Crime Reporting) is B. not a truly reliable measure.

The UCR is a program established by the FBI in 1930 to collect and analyze crime statistics from law enforcement agencies across the United States. Although it provides useful data and insights into crime trends, it is not without its limitations. One significant issue with the UCR is that it relies on voluntary reporting from law enforcement agencies, meaning that some areas may not provide complete or accurate data. This can lead to an underrepresentation of certain crimes or inconsistencies in reporting across jurisdictions.

Another limitation is that the UCR only includes reported crimes, excluding any unreported criminal activity. This means that the data does not necessarily provide a comprehensive picture of all crimes occurring in a given area. Additionally, the UCR uses a hierarchy rule, meaning that if multiple crimes are committed during a single incident, only the most severe crime is counted. This can result in an undercounting of less severe but still significant crimes.

In summary, although the UCR provides valuable information on crime trends and patterns, it is not a truly reliable measure due to its reliance on voluntary reporting, exclusion of unreported crimes, and hierarchy rule. Therefore, the correct option is B.

heather and her two friends went to the nail salon to gte a manicure and a pedicure. manicures cost $18 and pedicures cost $30. heather upgraded her manicure to gel polish which costs an extra $10. The group paid 4% sales tax and left a tip that was about 5 times the ammount of tax they paid. How much did they spend in total including tax and tip. 

Answers

they spent a total of $215.76 including tax and tip.

What is the arithmetic operation?

The four fundamental operations of arithmetic are addition, subtraction, multiplication, and division of two or more quantities. Included in them is the study of numbers, especially the order of operations, which is important for all other areas of mathematics, including algebra, data management, and geometry. The rules of arithmetic operations are required in order to answer the problem.

Therefore, the total cost per person without tax and tip would be:

$28 + $30 = $58

Since there were three people, the total cost without tax and tip would be:

$58 × 3 = $174

The sales tax would be 4% of the total cost:

$174 × 0.04 = $6.96

The tip left was about 5 times the amount of tax, so:

Tip = $6.96 × 5 = $34.80

Therefore, the total cost including tax and tip would be:

$174 + $6.96 + $34.80 = $215.76

So, they spent a total of $215.76 including tax and tip.

In my bag, one coin is worth $50. The rest are worth $10. The average value of all the coins in my bag is $15. How many coins are in my bag?

Answers

There are 8 coins.

In my bag, one coin is worth $50. The rest are worth $10. The average value of all the coins in my bag is $15. How many coins are in my bag?

Let's say that there are x $10 coins in the bag. Then, the total value of these coins would be 10x.

We also know that there is one $50 coin in the bag, so the total value of all the coins in the bag is 10x + 50.

The average value of all the coins in the bag is $15, so we can set up the following equation:

(10x + 50)/(x + 1) = 15

Multiplying both sides by x+1, we get:

10x + 50 = 15(x + 1)

Expanding the right side, we get:

10x + 50 = 15x + 15

Subtracting 10x and 15 from both sides, we get:

35 = 5x

Solving for x, we get:

x = 7

So there are 7 $10 coins in the bag and 1 $50 coin, for a total of 8 coins in the bag.

Find an angle in each quadrant with a common reference angle with 340°

Answers

The angles with a common reference angle of 340° are:

20° (first quadrant)200° (second quadrant)160° (third quadrant)340° (fourth quadrant)

To find an angle in each quadrant with a common reference angle of 340°, we need to determine the reference angle of 340° and then find angles in each quadrant with that same reference angle.

The reference angle of 340° is found by subtracting the nearest multiple of 360°, which is 0°, from 340°. Therefore, the reference angle of 340° is 20°.

Quadrant I:

To find an angle in quadrant I with a reference angle of 20°, we simply take the reference angle itself, which is 20°.

Quadrant II:

To find an angle in quadrant II with a reference angle of 20°, we need to add the reference angle to 180°, which gives us 200°.

Quadrant III:

To find an angle in quadrant III with a reference angle of 20°, we need to subtract the reference angle from 180°, which gives us 160°.

Quadrant IV:

To find an angle in quadrant IV with a reference angle of 20°, we need to subtract the reference angle from 360°, which gives us 340° (which is the original angle we started with).

Therefore, the angles in each quadrant with a common reference angle of 20° are:

Quadrant I: 20°Quadrant II: 200°Quadrant III: 160°Quadrant IV: 340°

The complete question is:-

a memory researcher is testing an experimental behavioral treatment to see if it helps or hurts the memory of alzheimer's syndrome patients. after 3 months of treatment, she tests the patient's memories using a standardized test, and the data is presented below. the population mean for this test is 50. did the treatment affect the patients' memories? use .01 as the level of significance. 43 56 78 76 58 54 44 38 44 71 83 90 what is the correct interpretation of the finding?

Answers

H1 is a treatment that affects the patient's memory. Alternative hypothesis H1 indicates that the treatment affected the patient's memory.

To test this hypothesis, the researcher should compare the test result to the population mean of 50. Researchers will use a one-tailed t-test with a significance level of 0.01.

If the calculated t-value is greater than the critical value, the null hypothesis is rejected and the alternative hypothesis is accepted.

To perform a t-test, the researcher must calculate the mean, standard deviation, and t-value of the patient's test scores. The average is calculated by dividing the sum of the test scores by the number of test scores. The standard deviation is calculated as the square root of the sum of the squared deviations from the mean divided by the number of test scores minus one.

The t-value is calculated by dividing the difference between the mean of the patient's test scores and the population mean by the standard deviation of the patient's test scores, multiplied by the square root of the number of test scores.

If the calculated t-value is greater than the critical value, you can reject the null hypothesis and accept the alternative hypothesis that the treatment did indeed affect the patient's memory.

a new coffee shop can hold no more than 50 seats. the owner wants at least 20 of the seats to be stools and the remaining seats to be recliners. if x is the number of stools and y is the number of recliners, which graph represents the solution to the system of inequalities?

Answers

let us consider x as the number of stools and y be the number of recliners

therefore, total seats [tex]\leq[/tex] 50

= x + y [tex]\leq[/tex] 50

then, owner wants a least 20 of the seats to  be stools

x [tex]\geq[/tex] 20

the rest are the number of recliners.

the equation of inequality is x + y [tex]\leq[/tex] 50

x + y =50

if x = 0 and y = 50

if y = 0 and x = 50

therefore the joining points are (0, 50) and ( 50, 0) in the coordinate plan

0+0 [tex]\leq[/tex] 50

then the shaded region will contain the origin

Graphing of x [tex]\geq[/tex] 20

.

Step-by-step explanation:

Given:

[tex] \frac{4}{5} \: and \: \frac{5}{7} [/tex]

a) In order to find the larger fraction, we have to make their denominator the same (it's 35 (multiply both fractions' denominators) in this case)

[tex] \frac{4 \times 7}{35} = \frac{28}{35} [/tex]

[tex] \frac{5 \times 5}{35} = \frac{25}{35} [/tex]

[tex] \frac{28}{35} > \frac{25}{35} [/tex]

It has led the world on a continuing adventure of human exploration, discovery, and achievement. The center has played an important role in bringing the United States into the 21st century through technological inventions and scientific discoveries. The people who work at JSC have made advances in science, technology, engineering, and medicine. This has helped people explore our world and outer space and gain endless knowledge from that exploration.2 The Johnson Space Center was established in 1961 as the Manned Spaceflight Center. It was the home and Mission Control Center for the U.S. human spaceflight program. In 1973, it was renamed in honor of the late President, and Texas native, Lyndon B. Johnson. The Johnson Center's complex occupies 1,620 acres of land southeast of downtown Houston. JSC presently serves as the home of mission control, lead for NASA's International Space Station operations and missions, home to the Orion Multi-Purpose Crew Vehicle, and base for many other advanced human exploration projects.3 The Lyndon B. Johnson Space Center holds several artifacts that are worth a visit. For example, several historic space capsules are on display at the space center. They include the Faith 7 Mercury capsule flown by Gordon Cooper; Gemini 5, flown by Gordon Cooper and Pete Conrad; and the Apollo 17 Command Module, flown to the Moon and back by Gene Cernan, Ronald Evans, and Harrison Schmitt. NASA's latest-generation space capsule, Orion, is also on display.4 Along with the space capsules, the JSC holds the famous Lunar Module; it hangs from the ceiling. This spacecraft, named LTA-8, served as a test unit for astronaut training. The spacecraft from which six astronauts descended to the surface of the Moon had the same design as LTA-8. Their Lunar Modules acted as their base while on the Moon. Later, it helped them return to the Lunar Orbit when their stay was over. The Apollo 13 Lunar Module acted as a lifeboat after that flight's Service Module was damaged. It helped the crew return safely to Earth.5 NASA's robots called Robonauts are also designed at the Johnson Space Center. One such robot is currently at the International Space Station. The Space Vehicle Mockup Facility in Building 9 at the space center is a good place to see the Robonauts. Some tours let people see the inside of the building from above. Other special tours take people across the building floor for a close-up look at Robonauts and other wonders at the space center.6 The Lyndon B.
