**Answer:**

a. Maximum

b. (-1, 4)

c. -3, 1

d. x = -1

**Step-by-step explanation:**

a. There is a maximum value of the function (highest point) because the parabola opens downward.

b. The vertex is the turning point--the point where the maximum is.

c. The roots (or "zeros") are the values of x where the curve intersects the x-axis

d. The axis of symmetry is a vertical line which passes through the vertex.

Imagine a simple process in which 5 ticket booths are selling tickets for an opera. If customers are coming at a rate of 15 / hour, and the utilization of the 5 booths is 50%, then how long does a customer spend at a booth (each customer goes to only one booth)?

### Answers

**Answer: **The customer spends 10 minutes at a booth.

**Step-by-step explanation:**

Let n= number of booths, [tex]\rho[/tex] = utilization, [tex]\lambda[/tex] = arrival rate, [tex]\mu=[/tex]Service rate

We know that

[tex]\rho=\dfrac{\lambda}{\mu\times n}[/tex]

As per given,

[tex]0.5=\dfrac{15}{\mu\times5}\\\\\Rightarrow\ \mu=\dfrac{15}{5\times0.5}\\\\\Rightarrow\ \mu=6[/tex]

Service rate = 6 customers per hour.

Time taken by each customer = [tex]\frac{1}{\mu}[/tex]

[tex]=\frac{1}{6} \ hours \ or\ \dfrac{60}{6}\ minutes\\\\=10 \ minutes[/tex]

Hence, **the customer spends 10 minutes at a booth.**

### Answers

**Answer:**

(3,3)

**Step-by-step explanation:**

Linear equations of lines are given in the form:

y = mx + b;

where m is the slope of the line, b is the y intercept and x, y are variables.

From the graph, we can see that line 1 passes through (0,6) and (6,0) while line 2 passes through (0, 1) and (6, 5).

The equation of line 1 is given as:

[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)\\\\y-6=\frac{0-6}{6-0} (x-0)\\\\y=-x + 6\ \ \ (1)[/tex]

The equation of line 2 is given as:

[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)\\\\y-1=\frac{5-1}{6-0} (x-0)\\\\y=\frac{2}{3}x + 1\ \ \ (2)[/tex]

Solving equation 1 and 2 simultaneously by subtracting equation 1 from 2 gives:

(5/3)x - 5 = 0

(5/3)x = 5

x = 3

Put x = 3 in equation 1:

y = -3 + 6 = 3

Therefore the two lines meet at (3, 3).

### Answers

**Answer:**

**7.** 75.36 inches

**8.** 21 inches

**9.** 13 inches

**Step-by-step explanation:**

**7. ***Circumference = π × d*

The diameter would be two times the radius, or 2 × 12 = 24. So, circumference would be 3.14 × 24 = **75.36 inches.**

**8. ***Circumference = π × d*

If we move variables around, *d = Circumference / π*

So, d = 65.94 / 3.14 = **21** **inches.**

**9. **To do this, let's figure out the diameter: *d = Circumference / π*

d = 81.64 / 3.14 = 26. Now the diameter is two times the radius, so to get the length of the radius, we must divide the diameter in half. 26 / 2 = **13 inches**.

Ms. Harper knows that her students in a computing course can choose from one of three operating systems for the semester: Doors, Banana, or Duix. Ms. Harper wants to test the hypothesis that her students will select the operating systems in the same proportion as students in other computing courses at the university. She conducts a χ2 goodness-of-fit test and calculates χ2=3.79 with a corresponding p-value of 0.15. Which of the following is correct at a 5-percent level of significance?

A. Reject the null hypothesis, since 3.79 > 2.

B. Fail to reject the null hypothesis, since 3.79 > 2.

C. Reject the null hypothesis, since 0.15 > 0.05.

D. Fail to reject the null hypothesis, since 0.15 > 0.05.

E. Reject the null hypothesis, since 0.15 < 3.79.

### Answers

**Answer:**

D. Fail to reject the null hypothesis, since 0.15 > 0.05.

**Step-by-step explanation:**

**P-value and decision regarding null hypothesis:**

If the p-value is larger than the significance level, we do not the null hypothesis.

Otherwise, we reject the null hypothesis.

**In this question:**

The test statistic is χ2=3.79, with a p-value of 0.15.

The level of significance is 0.05.

Since 0.15 > 0.05, we fail to reject the null hypothesis, and the correct answer is given by **option D.**
