F. Cannot be determined

Answers

Answer:

D. 5

Step-by-step explanation:

Based on the midsegment theorem of a trapezoid, thus:

QR = ½(OP + MN)

Substitute

27 = ½((5x - 7) + (6x + 6))

27 = ½(5x - 7 + 6x + 6)

Add like terms

27 = ½(11x - 1)

Multiply both sides by 2

2*27 = 11x - 1

54 = 11x - 1

54 + 1 = 11x

55 = 11x

55/11 = x

5 = x

x = 5

At a recent meeting, the manager of a national call center for a major Internet bank made the statement that the average past-due amount for customers who have been called previously about their bills is now no larger than $20. Other bank managers at the meeting suggested that this statement may be in error and it needs to be tested. The file called Bank Call Center attached below, contains data for a random sample of 67 customers from the call center population. What should be conducted based on the sample data? Test using α = 0.10

Answers

Answer:

As the calculated z does not fall in the critical region we fail to reject H0 and conclude that there is sufficient evidence that the average past-due amount for customers who have been called previously about their bills is now no larger than $23.

Step-by-step explanation:

As the standard deviation for the past due amounts is 63

The sample size n= 67

1) Formulate the null and alternate hypothesis

H0: u ≤ 23 against the claim Ha: u > 23

2)  The test statistics is

Z= x- u / σ/ √n

z= 20- 23/ 63/ √67

z= 0.00581

z= 0.006

3) The significance level ∝= 0.1

4) The critical value for ∝= 0.1 is Z > ±2.33

5) As the calculated z does not fall in the critical region we fail to reject H0 and conclude that there is sufficient evidence that the average past-due amount for customers who have been called previously about their bills is now no larger than $23.

70% of all US adults drink the cereal milk
Suppose this claim is true.
Find the standard deviation of the sampling
distribution of p

Answers

Answer: 0.0188

Step-by-step explanation:

Using the Central Limit Theorem, it is found that the standard deviation of the sampling  distribution of p is 0.0144.

Central Limit TheoremBy the Central Limit Theorem, the sampling distribution of sample proportions of a proportion p in a sample of size n has mean [tex]\mu = p[/tex] and standard deviation [tex]s = \sqrt{\frac{p(1 - p)}{n}}[/tex].

In this problem:

Suppose that 70% of all US adults drink the cereal milk, hence [tex]p = 0.7[/tex].A sample of 1012 adults is taken, hence [tex]n = 1012[/tex].

Then, the standard deviation is:

[tex]s = \sqrt{\frac{p(1 - p)}{n}} = \sqrt{\frac{0.7(0.3)}{1012}} = 0.0144[/tex]

The standard deviation of the sampling  distribution of p is 0.0144.

The figure below consists of a square and a right triangle. Find the missing length x.

Answers

Answer:

15 cm

Step-by-step explanation:

Since the square's side length is 8 cm, and one of its sides is the short leg of the triangle, the short leg of the triangle is 8 cm

Using the pythagorean theorem, solve for b (the missing side length x)

a² + b² = c²

8² + b² = 17²

64 + b² = 289

b² = 225

b = 15

So, the missing side length is 15 cm

Kyle ordered 7 large pepperoni pizzas from Wild Bill's Pizza, and he used the coupon shown above. If the total bill, after kyle used the coupon, was $82.50, what was the regular price of 1 pizza?

Answers

Answer:

Regular price of 1 pizza = $15 {Assuming discount coupon = $22.5}

Step-by-step explanation:

Let regular non discounted price of 7 pizzas be x

x - 22.5 = 82.5

x = 82.5 + 22.5

x = 105 (Regular Non discounted price of 7 pizzas)

Regular Price of 7 pizzas = 105

Regular price of 1 pizza = 105 / 7 = 15

The function f is defined by f(x) = x^2-2x-24

Answers

Step-by-step explanation:

my guess it's 4

(x+7) (x-3)

The value of k for which f(x + 3) = x^2+kx-21 for the considered function f(x) is found to be k = 4

How to evaluate a given mathematical expression with variables if values of the variables are known?

You can simply replace those variables with the value you know of them and then operate on those values to get a final value. This is the result of that expression at those values of the considered variables.

It is given that:

[tex]f(x) = x^2 -2x - 24[/tex]

and [tex]f(x+3) = x^2 + kx - 21[/tex]

Putting x = x+3 in the definition of f(x), we get:

[tex]f(x+3) = (x+3)^2 -2(x+3) -24\\\\f(x+3) = x^2 + 6x + 9 -2x -6 - 24\\\\f(x+3) = x^2 + 4x -21[/tex]

Comparing it with [tex]f(x+3) = x^2 + kx - 21[/tex], we see that k is having value as 4 for the considered function.

Thus, the value of k for which f(x + 3) = x^2+kx-21 for the considered function f(x) is found to be k = 4
