the equation y=1 does not represent a direct variation, whereas the other three equations given do represent direct variation.

What is Direct variation?

Direct variation is a relationship between two variables in which one is a constant multiple of the other. This means that if one variable increases, the other variable will also increase by a proportional amount. In other words, direct variation can be represented by the equation y=kx, where k is the constant of variation.

Out of the four equations given, the equation y=1 does not represent a direct variation. This is because the equation is not a function of x. In other words, no matter what value of x we choose, y will always be equal to 1. This means that the two variables, x and y, are not related to each other in any way. Therefore, there is no constant k that can be multiplied by x to get y.

On the other hand, the other three equations do represent direct variation. For example, in the equation y=x, y is equal to x multiplied by the constant k=1. Similarly, in the equation y=-5x, y is equal to x multiplied by the constant k=-5. Finally, in the equation y=0.9x, y is equal to x multiplied by the constant k=0.9.

In summary, the equation y=1 does not represent a direct variation, whereas the other three equations given do represent direct variation.

Step-by-step explanation:

All you have to do is and for perimeter.

Answer: The median changed the most.

Old median = 79.5

new median = 86.5

===============================================

Explanation:

To find the mean, we add up the values and divide by 12 since there are 12 numbers in this list.

mean = (add up the values)/(number of values)

mean = (58+61+71+77+91+100+105+102+95+82+66+57)/12

mean = 80.41667 approximately

--------

To get the median, we need to sort the numbers from smallest to largest

57, 58, 61, 66, 71, 77, 82, 91, 95, 100, 102, 105

There are n = 12 items in this set.

Because n = 12 is an even number, the median is between slots n/2 = 12/2 = 6 and 7

The midpoint of those values is (77+82)/2 = 79.5 which is the median.

--------

The range is the difference between the min and max

range = max - min = 105 - 57 = 48

The IQR will involve splitting the sorted set into two halves

L = lower half = stuff below the median

L =  {57, 58, 61, 66, 71, 77}

U = upper half = stuff above the median

U = {82, 91, 95, 100, 102, 105}

The median of set L is (61+66)/2 = 63.5 which is the value of Q1.

The median of set U is (95+100)/2 = 97.5 which is the value of Q3

IQR = interquartile range

IQR = Q3 - Q1

IQR = 97.5 - 63.5

IQR = 34

--------

Here is a summary of what we calculated

If we were to replace the "71" with "93", and redo the calculations, then we'll get these results:

The range and IQR stay the same, but the mean and median values are different.

Let's see which of those two values changed the most.

The median has changed the most because the +7 is larger than +1.83333

Answer:

(b/2)² + 1 = x² - 3x + (b/2)²

b²/4 + 1 = x² - 3x + b²/4

b²/4 - b²/4 = x² - 3x - 1

x² - 3x - 1 = 0

x² - 3x = 1

x² - 3x + 9/4 = 1 + 9/4

(x - 3/2)² = 13/4

x - 3/2 = ±(√13/4)

x = ±√13/2 + 3/2

so the number that must be added will be 3/2

Step-by-step explanation:

To graph the boundary lines of the linear inequalities, we need to first set up the inequalities based on the given information. Let x be the number of popcorn bags and y be the number of cotton candy bags. Then we have:

Chris needs at least 7 bags of popcorn, so the inequality for popcorn is x ≥ 7.

Chris has $56 to spend, so the total cost of popcorn and cotton candy cannot exceed $56, which gives the inequality 3x + 7y ≤ 56.

To graph the boundary lines, we need to first graph the lines corresponding to these two inequalities:

The line x = 7 is a vertical line passing through the point (7,0), because the only restriction on the popcorn is that Chris needs at least 7 bags.

The line 3x + 7y = 56 is a diagonal line with x-intercept 56/3 and y-intercept 8, because these are the points where the line intersects the x and y axes, respectively.

We can now plot these lines on a coordinate plane:

|

8 | x = 7

| o

7 | |

| | 3x + 7y = 56

6 | |

| o

5 |

4 |

2 | o

1 | o

|____________________________

1 2 3 4 5 6 7 8 9 10

The shaded region below and to the left of the diagonal line represents the solution set to the inequalities, because it includes all the points where Chris can buy at least 7 bags of popcorn and stay within his budget.

Finally, we can plot the given points and identify which ones are part of the solution set:

(3, 7) is not part of the solution set because it is above the diagonal line.

(2, 2) is part of the solution set because it is below and to the left of the diagonal line.

(8, 1) is not part of the solution set because it is above the diagonal line.

(10, 2) is not part of the solution set because it is above the diagonal line.

(5, 5) is part of the solution set because it is below and to the left of the diagonal line.

Therefore, the solution set consists of the points (2, 2) and (5, 5).

Answer:

and H(3,7), I(2,2), J(5,2).

To solve for the perimeter, we need to find the distance between each pair of consecutive points and add them up.

The distance between E and F is 3 units, between F and G is approximately 5.83 units, between G and H is 5 units, between H and I is approximately 5.83 units, and between I and J is 3 units.

So the perimeter of EFG is approximately 22.66 units.

Now, we need to check if HIJ has the same side lengths.

The distance between H and I is 5 units, between I and J is 3 units, and between J and H is approximately 5.83 units.

Therefore, HIJ does not have the same side lengths as EFG since their perimeters are different.

Answer:

The volume of a cylinder is given by the formula: V = πr^2h where r is the radius and h is the height. Substituting the given values, we get: V = π(4 in)^2(3 in) V = π(16 in^2)(3 in) V = 48π in^3 Therefore, the volume of wax needed to make one candle is 48π cubic inches. To find the amount of wax needed for 120 candles, we can multiply the volume of one candle by the number of candles: Amount of wax = 48π in^3/candle × 120 candles Amount of wax = 5760π in^3 So the company will need 5760π cubic inches of wax to make 120 candles.

Answer:

Therefore, the volume of the cylinder is approximately 2,262.9 cubic centimeters.

Step-by-step explanation:

The formula for the volume of a cylinder is V = πr^2h, where r is the radius of the base and h is the height of the cylinder.

Substituting the given values, we get:

V = π(6 cm)^2(20 cm)

V = 720π cm^3

To find the volume to the nearest tenth, we can use the approximation π ≈ 3.14 and calculate:

V ≈ 720(3.14) cm^3

V ≈ 2,262.8 cm^3

Rounding to the nearest tenth, we get:

V ≈ 2,262.8 cm^3 ≈ 2,262.9 cm^3

Therefore, the volume of the cylinder is approximately 2,262.9 cubic centimeters.

The probability that a randomly selected lobster weighs more than 2.5 lb is 0.0026.

Let X be the weight of a randomly selected Maine lobster. We know that X is normally distributed with mean μ = 1.8 lb and standard deviation σ = 0.25 lb.

We need to find the probability that a randomly selected lobster weighs

a) less than 1.5 lb

b) between 1.6 and 2 lb

c) more than 2.5 lb

To solve these problems, we need to standardize the variable X using the standard normal distribution

Z = (X - μ) / σ

a) To find the probability that a randomly selected lobster weighs less than 1.5 lb, we need to find P(X < 1.5). Standardizing X, we have

Z = (1.5 - 1.8) / 0.25 = -1.2

Using a standard normal distribution table or calculator, we find that P(Z < -1.2) = 0.1151.

Therefore, the probability that a randomly selected lobster weighs less than 1.5 lb is 0.1151.

b) To find the probability that a randomly selected lobster weighs between 1.6 and 2 lb, we need to find P(1.6 < X < 2). Standardizing X, we have

Z1 = (1.6 - 1.8) / 0.25 = -0.8

Z2 = (2 - 1.8) / 0.25 = 0.8

Using a standard normal distribution table or calculator, we find that P(-0.8 < Z < 0.8) = 0.5328

Therefore, the probability that a randomly selected lobster weighs between 1.6 and 2 lb is 0.5328.

c) To find the probability that a randomly selected lobster weighs more than 2.5 lb, we need to find P(X > 2.5). Standardizing X, we have:

Z = (2.5 - 1.8) / 0.25 = 2.8

Using a standard normal distribution table or calculator, we find that P(Z > 2.8) = 0.0026.

Answer: [tex]\frac{21}{8}[/tex] or 2.625

Step-by-step explanation:

Improper fractions

First, we want to convert 1 3/4 to an improper fraction.

We multiply the denominator(4)  by the coefficient (1) and add it to the numerator (3).

This gets us [tex]\frac{7}{4}[/tex]

Keep change flip

When dividing fractions, a helpful thing to remember is "keep change flip"

This means you keep the first number as it is, change the division sign to multiply, and flip the divisor, in this case 2/3, to be 3/2.

So, the problem becomes [tex]\frac{7}{4} *\frac{3}{2}[/tex]

Now, you jut multiply the numerators and denominators

The difference in the account balance between a simple interest and a compound interest over an 8-year time period, rounded to the nearest cent, is $12,189.02.

To calculate the difference in the account balance between simple interest and compound interest over 8 years, we first need to determine the final balance for each case.

Simple Interest:

Simple interest is calculated as a percentage of the initial principal (or the original amount deposited) and is paid only on the principal amount. The formula for simple interest is:

I = P * r * t

where I is the interest earned, P is the principal amount (in this case, $5,000), r is the annual interest rate (as a decimal), and t is the time period in years.

For this problem, the interest rate is given as 31%, which is equivalent to 0.31 as a decimal. Therefore, we have:

I = $5,000 * 0.31 * 8 = $12,400

The final balance for simple interest is the sum of the principal and the interest earned:

Final balance (simple interest) = $5,000 + $12,400 = $17,400

Compound Interest:

Compound interest is interest that is calculated on both the principal amount and any accumulated interest. The formula for compound interest is:

A = P * (1 + r/n)^(n*t)

where A is the final amount, P is the principal amount, r is the annual interest rate (as a decimal), n is the number of times per year that interest is compounded, and t is the time period in years.

For this problem, the interest rate is 31% and the account is compounded annually, so n = 1. Therefore, we have:

A = $5,000 * (1 + 0.31/1)^(1*8) = $29,589.02

The final balance for compound interest is the amount we just calculated:

Final balance (compound interest) = $29,589.02

The difference in the two account balances is:

$29,589.02 - $17,400 = $12,189.02

Therefore, the difference in the account balance between a simple interest and a compound interest over an 8-year time period, rounded to the nearest cent, is $12,189.02.

We have verified the identity of the expression 1 + cos(x) / cot(x) + cos(x) = sec(x) using the Pythagorean Identity.

The mathematical subject of trigonometry is the study of the connections between the angles and sides of triangles.

let's rewrite the expression using sine and cosine:

1 + cos(x) / cot(x) + cos(x) = sec(x)

cot(x) is the same as cos(x)/sin(x), so we can substitute:

1 + cos(x) / (cos(x)/sin(x)) + cos(x) = sec(x)

Simplifying the expression in the denominator:

1 + cos(x) * (sin(x)/cos(x)) + cos(x) = sec(x)

Canceling out the cos(x) terms in the numerator:

1 + sin(x) + cos(x) = sec(x)

Now, let's use the Pythagorean Identity:

sin²(x) + cos²(x) = 1

Divide both sides by cos²(x):

tan²(x) + 1 = sec²(x)

Substitute tan(x) for sin(x)/cos(x):

(sin²(x)/cos²(x)) + 1 = sec²(x)

Multiply both sides by cos²(x):

sin²(x) + cos²(x) = cos²(x)sec²(x)

Substitute cos²(x) with 1 - sin²(x):

sin²(x) + (1 - sin²(x)) = (1 - sin²(x))sec²(x)

Simplify:

1 = sec²(x)

Taking the square root of both sides:

1 = sec(x)

Therefore, the identity is verified.

Smallest number of calls for at least one emergency call is 20.

Probability that all six calls are emergencies is,

P(all six are emergencies) = (0.15)^6

                                           ≈ 0.000001

Probability that all six calls are emergencies is approximately 0.000001.

Probability that two or more calls are not emergencies,

Calculate it by the complement of the probability that all six calls are emergencies, and then subtracting this from 1,

P(at least two are not emergencies)

= 1 - P(all six are emergencies)

= 1 - (0.15)^6

≈ 0.999999

Probability that two or more calls are not emergencies is approximately 0.999999.

Let X be the number of calls that need to be answered to be at least 96%.

At least one call is an emergency.

Calculate the smallest value of X ,

P(at least one call is an emergency) ≥ 0.96

Using the complement rule,

P(no call is an emergency) ≤ 1 - 0.96 = 0.04

Each call is independent,

Probability that no call is an emergency can be calculated as,

P(no call is an emergency) = 0.85^X

a. The two parameters of the gamma distribution are

shape parameter (α) and velocity parameter (β).

The mean of the gamma distribution = α/β and the standard deviation = sqrt(α)/β.

mean = 5 seconds

standard deviation =2.5 seconds.

α/β = 5 (equation 1)

sqrt(α)/β = 2.5 (equation 2)

Squaring equation 2 and multiplying both sides by β^2 yields:

[tex]α = 6.25β^2[/tex]

Substituting this value of α into Equation 1 yields:

[tex]6.25β^2/β = 5[/tex]

Simplified, it looks like this:

β = 0.8

Substituting this value of β into Equation 1 yields:

a = 4

Therefore, the parameters of the gamma distribution are α = 4 and β = 0.8.

b. I need to find the probability that this software will take more than 10 seconds to run.

The probability density function (PDF) of the gamma distribution is given by

[tex]f(x) = (β^α * x^(α-1) * e^(-βx)) / Γ(α)[/tex]

where Γ(α) is the gamma function.

Using the values ​​of α and β obtained in part (a), we can write the PDF as

I need to find the probability that the execution time exceeds 10 seconds. This can be written as:

P(X > 10) = ∫(10 to infinity) f(x) dx

Using software or a calculator, we can evaluate this integral to get:

P(X > 10) = 0.0559 (rounded to four decimal places)

Therefore, the probability is 0.0559.

c.Since it has already taken more than 5 seconds, we need to find the probability of this software where will take more than 10 seconds to run.

This is a conditional probability and should be calculated using Bayes' theorem.

P(X > 10 | X > 5) = P(X > 10 and X > 5) / P(X > 5)

The numerator can be simplified to

P(X > 10 and X > 5) = P(X > 10)

Using the results obtained in part (b), we can write

P(X > 10 and X > 5) = 0.0559

The denominator can be written as:

P(X > 5) = ∫(5 to infinity) f(x) dx

Using the same PDF as before, we can evaluate this integral and get:

P(X > 5) = 0.2615 (rounded to four decimal places)

Substituting these values ​​into the conditional probability formula gives:

P(X > 10 | X > 5) = 0.0559 / 0.2615

Simplified, it looks like this:

P(X > 10 | X > 5) = 0.214

Therefore, the probability that his single run of this software took longer than 5 seconds to take longer than 10 seconds is 0.214 (rounded to three decimal places).

Answer:

y = [tex]\frac{4}{3}[/tex]x - 3

Step-by-step explanation:

Oof... I haven't done this in a while, but here you go! Slope-intercept form is y=mx+b, and in this one, the y-intercept is -3, just to get that out of the way. Now, the slope is the rise over the run, and I'm going to use the points (3, 1) and (6, 5) to measure the rise and run. The change in y, or the rise, is 4, while the change in x, or the run, is 3, so the slope is 4/3. Hope this was helpful!

Answer:

[tex]y = \dfrac{4}{3}x - 3[/tex]

Step-by-step explanation:

The slope-intercept form of a line is defined as:

[tex]y=mx+b[/tex],

where [tex]m[/tex] is the line's slope, and [tex]b[/tex] is the y-coordinate of its y-intercept.

We can see that the slope of the line is:

slope = rise / run = 4/3

(See the attached image for a model of rise and run.)

We can also see that the line touches the y-axis when y = -3, so this is the y-coordinate of the line's y-intercept.

With these pieces of information, we can craft the line's equation in slope-intercept form:

[tex]y = \dfrac{4}{3}x - 3[/tex]

The probability that the water in Willow Pond will have a pH of 7 in at least 4 out of 5 tests is approximately 0.0278 or 2.78%

This means that it is not very likely that the pond water will have a pH of 7 in at least 4 out of Laura's 5 tests.

Laura's simulation involves picking a shell from a bag with 3 green shells and 7 white shells.

Each pick represents one of Laura's tests, and picking a green shell represents a pH of 7.

Based on the results of 300 trials, we can calculate the probability of getting at least 4 green shells (pH of 7) out of 5 tests using the binomial distribution formula:

P(X >= 4) = 1 - P(X < 4)

= 1 - (P(X=0) + P(X=1) + P(X=2) + P(X=3))

where X is the number of green shells (pH of 7) in 5 tests.

Using the table, we can see that P(X=0) = 50/300, P(X=1) = 109/300, P(X=2) = 92/300, and P(X=3) = 40/300.

Therefore,

P(X >= 4) = 1 - (50/300 + 109/300 + 92/300 + 40/300) = 0.0278.

The experimental probability of selecting a green marble on the next attempt is 1/6 or approximately 0.1667 or 16.67%.

What is probability?

Probability is a measure of the likelihood of an event occurring.

The experimental probability of an event happening is calculated by dividing the number of times the event occurs by the total number of trials or attempts.

In this case, Diane has already selected 2 green marbles and 10 other marbles from the bag. So, the total number of marbles left in the bag is 12.

Since there are 2 green marbles left in the bag, the probability of selecting a green marble on the next attempt is:

2 (number of green marbles) / 12 (total number of marbles) = 1/6

So, the experimental probability of selecting a green marble on the next attempt is 1/6 or approximately 0.1667 or 16.67%.

The value of x in the given inequality is x is greater than or equal to 16.

Using symbols like (less than), > (greater than), (less than or equal to), or (greater than or equal to), an inequality compares two values or expressions and illustrates their connection (not equal to). When values or phrases are being compared, it is said that there exist inequalities. For instance, the inequality x + 2 7 signifies that "x plus 2 has a value less than 7."

The given inequality is x - 4 ≥ 12.

Add 4 on both sides of the inequality:

x - 4 + 4 ≥ 12 + 4

x ≥ 16

We can find y by solving for the length of CN: CN = Sy - BC = 600 - 0 = 600 So the values of x and y are:
x = 0 , y = 600

First, we can look at the corresponding sides of triangle ABC and triangle MNC. Since we know that these triangles are

similar (as indicated by the ~ symbol), we can set up the following proportion:

AB/AM = BC/CN

We can substitute in the given values for these lengths:

4x/2x = (Lv + Sy)/Sy

Simplifying this equation, we can cancel out the common factor of 2x on the left side:

2 = (Lv + Sy)/Sy

Multiplying both sides by Sy, we can isolate the sum of Lv and Sy:

2Sy = Lv + Sy

Combining like terms, we get:

Sy = Lv

So we now know that Sy is equal to Lv, which is 600.

To solve for x and y, we can use the fact that corresponding sides are in proportion. Specifically, we can look at the ratio of the length of AB to the length of AM:

AB/AM = 4x/Lv

Substituting in the values we know, we get:

AB/AM = 4x/600

We can also look at the ratio of the length of BC to the length of CN:

BC/CN = 2x/Sy

Substituting in the values we know, we get:

BC/CN = 2x/600

Since AB and BC are corresponding sides in triangle ABC and AM and CN are corresponding sides in triangle MNC, we

know that these ratios must be equal:

4x/600 = 2x/600

Simplifying this equation, we get:

4x = 2x

Subtracting 2x from both sides, we get:

2x = 0

Dividing both sides by 2, we get:

x = 0

Since x is 0, we can't solve for it any further. However, we can solve for y by using the ratio we found earlier:

AB/AM = 4x/600 = 0/600 = 0

Since AB is 0, we know that BC is also 0 (since the sum of the lengths of the sides of a triangle must be greater than 0).
