Algebraically, the point (1, -5) satisfies the first inequality, but it does not satisfy the second inequality because -5 is not greater than -5. Graphically, the point (1, -5) lies in the shaded area of the first inequality but lies on the dashed line of the second inequality, which is not inclusive. Therefore (1, -5) is not a solution to the given system of inequalities.

Answers

Since it only resolves one of the two inequalities, (1, -5) cannot be a solution to the given system of inequalities.

How are coordinates determined?

We must check that the point (1, -5) fulfils both inequalities in order to determine if it is a solution to the system of inequalities.

y > -6x - 11 is the first inequality. Inputting x = 1 and y = -5 results in:

[tex]-5 > -6(1) (1) - 11 \s-5 > -6 - 11 \s-5 > -17[/tex]

The first inequality is satisfied at the position (1, -5) since -5 is greater than -17.

y - x - 5 is the second inequality. Inputting x = 1 and y = -5 results in:

[tex]-5 ≥ -(1) (1) - 5 \s-5 ≥ -6[/tex]

The point (1, -5) does not satisfy the second inequality since -5 is not greater than -6.

Evaluate the difference quotienthf(x+h)−f(x)​Show all work.f(x)=4x2+1

Answers

The difference quotient for the function f(x) = 4x^2 + 1 is 8x

The difference quotient is a formula used to find the average rate of change of a function over an interval. It is represented by the formula: (f(x+h) - f(x))/h. In this case, we are asked to evaluate the difference quotient for the function f(x) = 4x^2 + 1.

Step 1: Substitute the function into the difference quotient formula:
(f(x+h) - f(x))/h = ((4(x+h)^2 + 1) - (4x^2 + 1))/h

Step 2: Simplify the expression:
= ((4x^2 + 8xh + 4h^2 + 1) - (4x^2 + 1))/h
= (8xh + 4h^2)/h

Step 3: Factor out h from the numerator:
= h(8x + 4h)/h

Step 4: Cancel out the h terms:
= 8x + 4h

Step 5: Substitute h = 0 to find the final answer:
= 8x + 4(0)
= 8x

Therefore, the difference quotient for the function f(x) = 4x^2 + 1 is 8x. This is the final answer for this Assignment. Remember to always show all work when evaluating the difference quotient.

MRNW is a kite, mRMN=5x-15, mR=11+45, nWNM=10y+30, and mW=8y

Answers

As per the given angle the value of x makes MRNW a kite is 6.66 degrees

Now, let's use the information given to us to find the value of x that makes MRNW a kite. We know that the angle ∠RMN is 5x - 15, and we know that the angle ∠R is 11x + 45. Since MR and RN are equal in length, we know that ∠RMN and ∠R are adjacent angles in a straight line. This means that their sum is equal to 180 degrees.

So, we can write an equation:

(5x - 15) + (11x + 45) = 180

Simplifying this equation, we get:

16x + 30 = 180

Subtracting 30 from both sides, we get:

16x = 150

Dividing both sides by 16, we get:

x = 9.375

To do this, we need to find the values of the other two angles in the kite. We know that the angle ∠WNM is 10y + 30, and we know that the angle ∠W is 8y.

So, we can write another equation:

(10y + 30) + (8y) = 180

Simplifying this equation, we get:

18y + 30 = 180

Subtracting 30 from both sides, we get:

18y = 150

Dividing both sides by 18, we get:

y = 8.333

Now, we need to check if these values of x and y make MRNW a kite. We can calculate the angles ∠M and ∠N using the information we have:

∠M = 180 - ∠RMN - ∠R

∠M = 180 - (5x - 15) - (11x + 45)

∠M = 150 - 16x

∠M = 7.5 degrees

∠N = 180 - ∠WNM - ∠W

∠N = 180 - (10y + 30) - (8y)

∠N = 142 - 18y

∠N = 6.666 degrees

So the domain of f cannot include any values of x such that x^(2)-4x-12=0. We can find these values of x by factoring and solving. x^(2)-4x-12=0 (x+2)(x-6)=0

Answers

The domain of f cannot include any values of x that make the equation x^(2)-4x-12=0 true. This is because if x satisfies this equation, then the denominator of the function f(x) will be zero, which is not allowed in a function's domain.

To find the values of x that satisfy this equation, you factored it to get (x+2)(x-6)=0. Now you can use the Zero Product Property to find the values of x that make each factor equal to zero.

For the first factor, x+2=0, we can solve for x by subtracting 2 from both sides to get x=-2. For the second factor, x-6=0, we can solve for x by adding 6 to both sides to get x=6.

So the values of x that satisfy the equation and are not included in the domain of f are x=-2 and x=6.

if 23% of all patients with high blood pressure have had side effects from a certain kind of medicin, so the normal approximation to the binomial to find the probability that among 120 this medicino more 32 will have had side effects.

Answers

The probability that no more than 32 patients out of 120 will have had side effects from the medicine is 0.8289.

The probability that a patient has side effects from the medicine is 23%, or 0.23. We can use the normal approximation to the binomial to find the probability that among 120 patients, no more than 32 will have had side effects.

First, we need to find the mean and standard deviation of the binomial distribution. The mean is np, where n is the number of trials (120 patients) and p is the probability of success (0.23). The mean is 120*0.23 = 27.6.

The standard deviation is sqrt(np(1-p)), or sqrt(120*0.23*(1-0.23)) = 4.65.

Now we can use the normal approximation to find the probability that no more than 32 patients will have had side effects. We need to find the z-score for 32, which is (32-27.6)/4.65 = 0.95. Using a z-table, we find that the probability of getting a z-score less than or equal to 0.95 is 0.8289.

Therefore, the probability that no more than 32 patients out of 120 will have had side effects from the medicine is 0.8289.

A boat is heading towards a lighthouse, whose beacon-light is 111 feet above the water. From point A, the boat’s crew measures the angle of elevation to the beacon, 11, before they draw closer. They measure the angle of elevation a second time from point B at some later time to be 21. Find the distance from point A to point B.

Answers

Let's denote the distance from point A to the lighthouse as x and the distance from point B to the lighthouse as y. We can use the tangent function to set up the following equations:

tan(11) = 111/x

tan(21) = 111/y

We want to solve for the value of y-x. We can rearrange the two equations above to solve for x and y, respectively:

x = 111/tan(11)

y = 111/tan(21)

Now we can substitute these expressions into y-x to get:

y-x = 111/tan(21) - 111/tan(11)

Using a calculator, we can evaluate this expression to get:

y-x ≈ 381.3 feet

Therefore, the distance from point A to point B is approximately 381.3 feet.

Suppose we are trying to estimate the average annual salary of all high school teachers in a particular region. After gathering data on 100 teachers, we have determined the sample mean to be $50,000 and the sample standard deviation to be $5,000. What is the t-statistic associated with this sample if information from the government reveals that the actual average salary (the population mean salary) is $49,000?

Answers

The t-statistic associated with this sample if information from the government reveals that the actual average salary is 2

The t-statistic can be calculated using the formula: t = (sample mean - population mean) / (sample standard deviation / √(sample size))

In this case, the sample mean is $50,000, the population mean is $49,000, the sample standard deviation is $5,000, and the sample size is 100.

Plugging these values into the formula, we get:

t = ($50,000 - $49,000) / ($5,000 / √(100))

t = $1,000 / ($5,000 / 10)

t = $1,000 / $500

t = 2

Therefore, the t-statistic for this sample indicates that the actual average pay is $2, according to data from the government.

Answers

The average of the first ten terms of the series is 306.9. Alternative C. is correct.

The average of the first ten terms in a geometric series can be found by using the formula for the sum of a geometric series and then dividing by the number of terms. The formula for the sum of a geometric series is:

S = a(1 - rⁿ) / (1 - r)

Where S is the sum, a is the first term, r is the common ratio, and n is the number of terms.

In this case, a = 3, r = 2, and n = 10. Plugging these values into the formula, we get:

S = 3(1 - 2¹⁰) / (1 - 2)
S = 3(-1023) / (-1)
S = 3069

Now, to find the average of the first ten terms, we simply divide the sum by the number of terms:

Average = S / n

Average = 3069 / 10

Average = 306.9

Therefore, the answer is (C) 306.9.

Answers

The difference quotient for the function f(x) = - 3x²- 7x + a + 2 is -6x - 3h.

To simplify the difference quotient, we first need to compute f(x+h) and f(x):

f(x+h) = -3(x+h)² - 7(x+h) + a + 2

= -3x² - 6hx - 3h² - 7x - 7h + a + 2

f(x) = -3x² - 7x + a + 2

Now, we can plug these values into the difference quotient:

f(x+h) - f(x)

= (-3x²- 6hx - 3h² - 7x - 7h + a + 2) - (-3x² - 7x + a + 2)

= -3x² - 6hx - 3h² - 7x - 7h + a + 2 + 3x² + 7x - a - 2

= -6hx - 3h^2

Finally, we divide by h and simplify:

The selling price of each cup of lemon juice is 3/2 times as much as the selling price of a cup of apple juice. For every 2 cups of lemon juice sold, Mr Tan sells 5 cups of apple juice. He earns $12 more from apple juice than from lemon juice. How much does Mr Tan earn altogether?

Answers

Mr Tan earns a total of $96.

How to solve this

Let the selling price of a cup of apple juice be x.

Then the selling price of a cup of lemon juice is 3/2 times x, which is (3/2)x.

Let the number of cups of lemon juice sold be L, and the number of cups of apple juice sold be A.

We know that for every 2 cups of lemon juice sold, Mr Tan sells 5 cups of apple juice. So we can write:

A = (5/2)L

His earnings from apple juice minus his earnings from lemon juice is $12. So we can write:

Ax - L(3/2)x = $12

Simplifying this equation, we get:

(5/2)Lx - (3/2)Lx = $12

Lx = $24

Now we can use this information to find the values of L and A:

L = $24/x

A = (5/2)L = (5/2)($24/x) = $60/x

Finally, we can calculate Mr Tan's total earnings by adding his earnings from apple juice and lemon juice:

Total earnings = Ax + L(3/2)x

= $60 + (3/2)($24)

= $96

Therefore, Mr Tan earns a total of $96.

The margin of error with a 99% level of confidence for the population average speed is 3.2375. The correct answer is option c. 3.2375.

To find the margin of error with a 99% level of confidence for the population average speed, we need to use the formula for margin of error:

Margin of error = (z-score) * (standard deviation / √sample size)

The z-score for a 99% level of confidence is 2.576. The standard deviation is 20 km/h and the sample size is 64. Plugging these values into the formula, we get:

Margin of error = (2.576) * (20 / √64)

Margin of error = (2.576) * (20 / 8)

Margin of error = (2.576) * (2.5)

Margin of error = 6.44

The margin of error with a 99% level of confidence for the population average speed is 6.44 km/h. However, we need to divide this value by 2 to get the margin of error on either side of the mean:

Margin of error = 6.44 / 2

Margin of error = 3.22

Therefore, the margin of error with a 99% level of confidence for the population average speed is 3.22 km/h, which rounds to 3.2375 km/h. The correct answer is option c. 3.2375.

The solution to the system is (x, y, z) = (6, 0, -2).

To solve the system, we can use the elimination method. First, we will eliminate x from the second and third equations by adding the first equation to them:

{5y - 10z = 20
{-3y + 4z = -8

Next, we will eliminate y from the second and third equations by subtracting the second equation from the third equation:

{15y - 30z = 60
{15y + 20z = -40
{-10z = 20

Now we can solve for z:
z = -2

Next, we can substitute z back into the second equation to solve for y:

5y - 10(-2) = 20
2y + 20 = 20
2y = 0
y = 0

Finally, we can substitute z and y back into the first equation to solve for x:

2x + 3(0) - 4(-2) = 20
2x + 8 = 20
2x = 12
x = 6

Assuming that the lifetime of the LED light bulb follows the exponential distribution, the probability that it will last more than 3 years is closest to (C) 53%. Correct answer is option C

This is because the lifetime of an LED light bulb can be estimated using the following equation : P(x > 3 years) = 1 - P(x ≤ 3 years)where x is the lifetime of the LED light bulb.If we convert 3 years to hours, we get 3 * 365 * 24 = 26280 hours. As a result, P(x ≤ 3 years) = P(x ≤ 26280 hours)

Using the formula for exponential distribution, the probability of the LED light bulb failing after 26280 hours is : Probability = 1 - e^{-λx} Where λ is the failure rate per hour and x is the length of time in hours.We can now calculate the value of λ by dividing the expected lifetime of the bulb by the total number of hours.

 λ = 1/25000 hours  This implies that the probability of the LED light bulb failing after 26280 hours is : P (x ≤ 26280 hours)

Therefore, the probability that the LED light bulb will last more than 3 years is approximately 53 percent. The Correct answer is option C

enesis has a part-time job at an ice skating rink selling hot cocoa. She decided to plot the number of hot cocoas she sold relative to the day's high temperature and then draw the line of best fit. Based on the line of best fit, what would you predict the day’s high temperature to be if Genesis sold 28 hot cocoas?

Answers

based on the line of best fit, we would predict that the day's high temperature would be approximately 34.29 degrees Fahrenheit or 1.272°C if Genesis sold 28 hot cocoas

what is temperature?

The term "temperature" describes how hot or cold a body is. It is, specifically, a method of calculating the kinetic energy of the particles that make up an item. When particles move more quickly, the temperature rises, and vice versa.

Nearly every aspect of our daily lives and all scientific fields, from physics to geology, are significantly influenced by temperature.

The velocity of these particles likewise increases as the temperature rises.

A thermometer or a calorimeter is used to determine the temperature. In other words, a system's internal energy is determined by its temperature.

from the question...

We may infer from the scatter plot and the line of best fit that the line's equation is y = -0.7x + 52, where y stands for the volume of hot cocoa sold and x for the high temperature of the day in degrees Fahrenheit.

If Genesis sold 28 hot cocoas, we can solve for x and substitute y = 28 into the equation to determine the day's high temperature:

28 = -0.7x + 52

-0.7x = 28 - 52

-0.7x = -24

x = 34.29

So, if Genesis sold 28 hot cocoas, we would forecast that the day's high temperature would be roughly 34.29 degrees Fahrenheit based on the line of best fit.

complete question:

1 year ago Wags the dog was 3 years more than 3 times the age of Scratch’s the cat. In the 2 years time Scratch will be 2 more than one quarter of Wags age. Find Wags and Scratch’s approximate ages today?

Answers

After solving the problem we found that Wags is approximately 15 years old and Scratch is approximately 5 years old today.

The solution uses algebraic equations and substitution to solve for the ages of Wags and Scratch, which is based on the concept of solving systems of linear equations.

Let's assume that Wag's age today is represented by W, and Scratch's age today is represented by S.

From the first piece of information, we can set up the following equation:

W - 1 = 3 + 3(S - 1)

Simplifying:

W - 1 = 3S - 6

W = 3S - 5

From the second piece of information, we can set up the following equation:

S + 2 = (1/4)(W + 2) + 2

Simplifying:

S + 2 = (1/4)W + 2.5

Substituting W = 3S - 5:

S + 2 = (1/4)(3S - 5) + 2.5

Solving for S:

S + 2 = (3/4)S - (5/4) + 2.5

S + 2 = (3/4)S + 3/4

1/4 S = 1 1/4

S = 5

Substituting S = 5 into W = 3S - 5:

W = 10 + 5

W = 15

Therefore, Wags is approximately 15 years old and Scratch is approximately 5 years old today.

Which is more massive, the total mass of all the humans or the total mass of all the ants? About how many times more massive is it? 4. Which is more massive, the total mass of all the krill or the total mass of all the blue whales? About how many times more massive is it?

Answers

By answering the above question, we may state that As a result, the equation mass of all krill is about 11,485 times more than the mass of all blue whales.

What is equation?

A mathematical equation is a process that links two statements and indicates equality using the equals sign (=). A formal statement that proves the equality of two calculations is known as an equation in algebra. For instance, the equal sign separates the numbers 3x + 5 and 14 in the equation 3x + 5 = 14. A mathematical formula may be used to understand the link between the two phrases that are inscribed on opposite sides of a letter. Frequently, the logo and indeed the particular software are identical. like in 2x - 4 = 2, for example.

Given that there are several species with a wide range in population numbers, it is challenging to identify which animal is the least numerous. The vaquita porpoise, Javan rhinoceros, and Amur leopards are some of the rarest animals, albeit they all exist in the wild. The number of ants on Earth is believed to be 10 quadrillion, which is around 10,000,000,000,000,000 times greater than the population of any of the rarest species.

The estimated mass of all krill on Earth is around 379 million tonnes, whereas the estimated mass of all blue whales is approximately 33,000 tonnes. As a result, the mass of all krill is about 11,485 times more than the mass of all blue whales.
