Answer:

a. C(x)= 15.75

b. She can bowl five games.

c. Mentioned in the explanation.

Step-by-step explanation:

Including the shoe rental, what is the total cost to bowl 4 games?

Step 1- Substitute the variable

C(x)= 3.5(4)+ 1.75

Step 2- Multiply

C(x)= 14+1.75

C(x)= 15.75

If Marnie has $22, how many games can she bowl if she must also rent bowling shoes?

Step 1- Subtract

22-1.75= 20.25

Step 2- Divide

20.25÷3.5= 5.79 *rounded

She can bowl 5 games.

What is the meaning of C(10)?

That means that x=10, or in other words, this person played 10 games.

Imagine you are at home watching television. You are sitting 6 feet away from your TV which is hung on the wall and the top of i

Kisachek [45]

You can trace a right triangle with these features:

- the 6 feet distance represents the horizontal distance from you to the TV, this is the base of the triangle or the adjacent leg

- the 8 feet distance is the vertical distance from the base of the triangle to the TV, this is the height of the triangle or opposite leg.

- the angle theta that you make with the top of your TV is

tan (theta) = opposite leg / adjacent leg = 8/6 =4/3

=> theta = arctan (4/3) = 53.13 degrees.

Answer: 53.103 degrees

Combine like terms. y + 5e + 3y

yan [13]

Let's begin by listing out the information given to us:

$y+5e+3y$

We proceed to combine like terms (the coefficients having the same variable), we have:

$\begin{gathered} y+3y+5e\Rightarrow4y+5e \\ \therefore4y+5e \end{gathered}$

Mathematics achievement test scores for 300 students were found to have a mean and a variance equal to 600 and 3600, respectivel

Zina [86]

Answer:

(a) Approximately 205 students scored between 540 and 660.

(b) Approximately 287 students scored between 480 and 720.

Step-by-step explanation:

A mound-shaped distribution is a normal distribution since the shape of a normal curve is mound-shaped.

Let <em>X</em> = test score of a student.

It is provided that $X\sim N(\mu = 600, \sigma^{2} = 3600)$ .

(a)

The probability of scores between 540 and 660 as follows:

$P(540\leq X\leq 660)=P(\frac{540-600}{\sqrt{3600} }\leq \frac{X-600}{\sqrt{3600} }\leq \frac{660-600}{\sqrt{3600} })\\=P(-1 \leq Z\leq 1)\\= P(Z\leq 1)-P(Z\leq -1)\\=0.8413-0.1587\\=0.6826$

Use the standard normal table for the probabilities.

The number of students who scored between 540 and 660 is:

300 × 0.6826 = 204.78 ≈ 205

Thus, approximately 205 students scored between 540 and 660.

(b)

The probability of scores between 480 and 720 as follows:

$P(480\leq X\leq 720)=P(\frac{480-600}{\sqrt{3600} }\leq \frac{X-600}{\sqrt{3600} }\leq \frac{720-600}{\sqrt{3600} })\\=P(-2 \leq Z\leq 2)\\= P(Z\leq 2)-P(Z\leq -2)\\=0.9772-0.0228\\=0.9544$

Use the standard normal table for the probabilities.

The number of students who scored between 480 and 720 is:

300 × 0.9544 = 286.32 ≈ 287

Thus, approximately 287 students scored between 480 and 720.
