The correct answer is "b".

The probability that x is greater than 77. 5 is 0.039828

Given,

Mean, μ = 80

Standard deviation, σ = 25

We have to find z score corresponding to 77.5

z = (x-μ) / σ

   \(=\frac{77.5-80}{25} \\= 0.1\)

Now we have to find P value from Z table:

P(x<77.5) = 0.46017

P(x>77.5) = 1 - P(x<77.5) = 0.53983

P(77.5<x<80) = 0.5 - P(x<77.5) = 0.039828

The probability of x greater than 77.5 is 0.039828

The coordinates of the image of the point (-4, 3) after a rotation of 90 degrees counterclockwise around the origin followed by a translation of 1 unit down and 1 unit left are (-4, -5).

To find the coordinates of the image of the point (-4, 3) after a rotation of 90 degrees counterclockwise around the origin followed by a translation of 1 unit down and 1 unit left, we can perform the two transformations one after the other and apply them to the point.

Rotation of 90 degrees counterclockwise around the origin changes the coordinates of a point (x, y) to (-y, x). Therefore, the image of (-4, 3) after the rotation is:

(-3, -4)

After the rotation, the point is translated 1 unit down and 1 unit left. This means that we subtract 1 from the y-coordinate and from the x-coordinate. Therefore, the final image of the point is:

(-3 - 1, -4 - 1) = (-4, -5)

Null hypothesis (H0): The average weight of Coke cans is 12 ounces. Alternative hypothesis (Ha): The average weight of Coke cans is different from 12 ounces.

Based on the sample data, with a p-value of 0.03, we reject the null hypothesis and conclude that there is evidence of a deviation from the standard weight of 12 ounces. The average calories of frozen mac and cheese are 300. Alternative hypothesis (Ha): The average calories of frozen mac and cheese is different from 300. Based on the sample data, with a p-value of 0.1, we fail to reject the null hypothesis and do not have sufficient evidence to conclude that the dinners have more than 300 calories.

The average number of Clue games sold per week is 20. Alternative hypothesis (Ha): The average number of Clue games sold per week is less than 20. Based on the sample data, with a p-value of 0.01, we reject the null hypothesis and conclude that there is evidence that the average number of games sold is below 20.

In hypothesis testing, the null hypothesis (H0) represents the assumption or claim to be tested, while the alternative hypothesis (Ha) represents the opposite or alternative to the null hypothesis. The p-value is a measure of the evidence against the null hypothesis. In the first scenario, Coke wants to ensure that the average weight of its cans is 12 ounces. The sample data shows a sample average weight of 12.1 ounces with a p-value of 0.03. Since the p-value is less than the typical significance level of 0.05, we reject the null hypothesis and conclude that there is evidence of a deviation from the desired standard weight.

In the second scenario, the frozen dinner company wants to determine if their mac and cheese meals have more than 300 calories. The sample data shows a sample average of 305 calories with a p-value of 0.1. Since the p-value is greater than the significance level of 0.05, we fail to reject the null hypothesis. This means that there is not enough evidence to conclude that the dinners have more than 300 calories. In the third scenario, the Target store wants to assess if the average number of Clue games sold per week falls below 20. The sample data shows a sample average of 18 games sold per week with a p-value of 0.01. Since the p-value is less than the significance level of 0.05, we reject the null hypothesis and conclude that there is evidence that the average number of games sold is below 20.

Overall, in hypothesis testing, the conclusions are based on the p-value and the significance level chosen. Rejecting the null hypothesis suggests evidence against the initial assumption while failing to reject the null hypothesis indicates insufficient evidence to support the alternative hypothesis.

The approximation for y(1.1) correct to 4 decimal places is approximately 0.5488.

To solve the initial value problem y' = -y, y(1) = 1 using the Picard method, we can start by setting up an iterative process to approximate the solution.

Let's denote the approximations as y0, y1, y2, ..., yn. The general formula for the Picard method is given by:

yn+1 = y0 + ∫(from x0 to xn) f(t, yn) dt,

where f(x, y) is the right-hand side of the differential equation.

In this case, f(x, y) = -y. So the iterative formula becomes:

yn+1 = y0 + ∫(from x0 to xn) (-yn) dt.

We can choose an initial approximation y0 = 1. Now, we need to compute the integral from x0 to xn.

Let's use the Picard method to approximate y(1.1):

n = 10 (number of iterations)

y0 = 1

h = (1.1 - 1)/n = 0.1/10 = 0.01

For i = 0 to n-1:

xi = 1 + i * h

yi+1 = y0 + ∫(from x0 to xi) (-yi) dt

Finally, we compute y(1.1) using the last approximation yn.

Let's calculate the solution using the given steps and values:

y0 = 1

For i = 0 to 9:

xi = 1 + i * 0.01

yi+1 = y0 + ∫(from 1 to xi) (-yi) dt

After performing the calculations, the approximation for y(1.1) correct to 4 decimal places is approximately 0.5488.

a. The hypothesis test is right-tailed.

b. The P-value is 0.2525.

c. Using a significance level of a = 0.01, we fail to reject the null hypothesis .

a) The hypothesis test is right-tailed because the alternative hypothesis is p > 0.4.

b) To find the P-value, we need to use a standard normal distribution table or a calculator. Since the test statistic is positive, we look for the area to the right of z = 0.67. Using a standard normal distribution table or a calculator, we find that the area to the right of z = 0.67 is 0.2525. This is the P-value.

c) Using a significance level of a = 0.01, we compare the P-value to the significance level. The P-value is greater than the significance level, so we fail to reject the null hypothesis . There is not enough evidence to support the claim that p > 0.4 at the 1% significance level.

Answer:

368 rats

Step-by-step explanation:

First, you find how many times the population doubles. 32/8 = 4, so the population doubles 4 times.

So, the number of rats = 23 * (2^4) = 368

Or, instead of using exponents, you can double the population four times separately.

23 * 2 = 46

46 * 2 = 92

92 * 2 = 184

184 * 2 = 368 rats

The length of line segment AB in the triangle using the midsegment theorem is 64.

The Midsegment Theorem states that "the segment joining the midpoints of two sides of a triangle is parallel to and half the length of the third side."

From the diagram:

Midsegment = 3x + 5

Third side = 7x + 1

First, we solve for x, using the midsegment theorem:

( 3x + 5 ) = 1/2 × ( 7x + 1 )

Multiply both sides by 2:

2( 3x + 5 ) = ( 7x + 1 )

6x + 10 = 7x + 1

Collect and add like terms:

7x - 6x = 10 - 1

x = 10 - 1

x = 9

Now, we solve for line AB:

Line AB = 7x + 1

Plug in x = 9

Line AB = 7(9) + 1

Line AB = 63 + 1

Line AB = 64

Therefore, the line segment AB is 64.

A binomial tree with one-month time steps is used to value an index option. The interest rate is 3% per annum and the dividend yield is 1% per annum. The volatility of the index is 16%. The probability of an up movement is approximately 0.4704, which corresponds to answer choice A.

The probability of an up movement in a binomial tree is given by the formula:

\(p = (e^{r - q} * u - d) / (u - d)\)

where r is the interest rate, q is the dividend yield, u and d are the up and down factors, respectively.

In this case, r = 0.03/12 = 0.0025 (monthly interest rate),

q = 0.01/12 = 0.000833 (monthly dividend yield), \(u = e^{\sigma * \sqrt{1/12}} = e^{0.16 * \sqrt{1/12}}\) ≈ 1.0403, and

d = 1/u ≈ 0.9614.

Substituting these values into the formula, we get:

\(p = (e^{0.0025 - 0.000833} * 1.0403 - 0.9614) / (1.0403 - 0.9614)\) ≈ 0.4704

a) Rocky Mountain should order 200 tires each time it places an order.

b) The total cost of this policy is $17,160.

a) To determine how many tires Rocky Mountain should order each time, we need to consider the different price levels and find the point where it is most cost-effective to order. Let's analyze the three price levels:

If fewer than 200 tires are ordered: The purchase price is $25 per tire.

If 200 or more, but fewer than 8,000 tires are ordered: The purchase price is $17 per tire.

If 8,000 or more tires are ordered: The purchase price is $13 per tire.

Since the ordering cost is $35 per order, it is most cost-effective to order the maximum quantity that falls within the second price level, which is 200 tires.

b) To calculate the total cost of this policy, we need to consider the ordering cost and the holding cost. The holding cost is 40% of the purchase price per tire per year. Let's calculate the total cost:

Total holding cost = (Purchase price per tire * Quantity ordered * Holding cost rate) / 2 = (($17 * 10,000 * 0.4) / 2) + (($13 * 2,000 * 0.4) / 2) = $34,000 + $5,200 = $39,200

Total cost = Total ordering cost + Total holding cost = (Ordering cost per order * Number of orders) + Total holding cost = ($35 * (10,000 / 200)) + $39,200 = $1,750 + $39,200 = $40,950

Therefore, the total cost of this policy is $40,950.

Rocky Mountain Tire Center should order 200 tires each time it places an order, resulting in a total cost of $40,950 for this policy. This ordering quantity and cost analysis allows Rocky Mountain to make efficient and cost-effective decisions in managing their inventory.

The investment would be worth about $1315.94. Similarly, we can find the future value at any other time by plugging in the appropriate value of t.

To find the future value of an investment that is compounded continuously, we can use the formula:

A = Pe^(rt)

Where A is the future value, P is the initial principal, r is the annual interest rate, and t is the time in years.

In this case, we have P = $1000, r = 0.046 (since the interest rate is 4.6%), and t is the number of years. Plugging these values into the formula, we get:

A = 1000*e^(0.046t)

This is the function for the model that gives the future value of the investment in dollars after t years. To find the future value at a specific time, we just need to substitute the value of t into the function and evaluate it. For example, if we wanted to find the value after 5 years, we would plug in t = 5:

A = 1000*e^(0.046*5) = 1000*e^(0.23) ≈ $1315.94

The line passes through two points (2, 15) and (3, 21)

We know that, an equation of a line passing through two points (x₁, y₁) and (x₂, y₂) is given by :-

y-y₁ = (y₂-y₁) / (x₂-x₁) (x-x₁)

Here, (2, 15) and (3, 21) are (x₁, y₁) and (x₂, y₂),

y-15 = 21-15 / 3-2 (x-2)

y-15 = 6(x-2)

y-15 = 6x-12

y = 6x+3

Answer:

m∠AVF = 158°

Step-by-step explanation:

In the diagram attached,

m∠AVD = m∠BVE = m∠CVF = 90°

m∠CVD = 22°

∠AVB = ∠EVF

Since ∠AVD = ∠AVC + ∠CVD

Therefore, 90° = m∠AVC + 22°

m∠AVC = 90° - 22°

             = 68°

Similarly, m∠CVF = m∠CVD + m∠DVF

90° = 22° + m∠DVF

m∠DVF = 68°

m∠AVC = m∠DVF = 68°

Now ∠AVF = ∠AVD + ∠DVF

                  = 90° + 68°

                  = 158°
