The domain is talking about the "range" of the horizontal axis therefore you will be focusing on the x-intercepts.

The answer will be All non-negative real numbers less than or equal to 18

because the x-intercepts lies at 0 and 18. The answer makes sense because the furthest you can go is 18 ft and the closest you could go is 0 ft. The "all non-negative real numbers" puts a restriction on the least distance it could travel so that means that it stops at 0 ft because if you go any further, you will end up in the negatives and it clearly states "non-negative".

What is the measure of each angle of a regular 17-gon? If necessary, round to the nearest tenth.

stich3 [128]

For a regular 17-gon, the measure of the internal angles is:

a = 158.8°

<h3>How to measure the internal angles?</h3>

The measure of the sum of the internal angles of a regular figure of N sides is:

(N - 2)*180°

For the case where N = 17, we have:

(17 - 2)*180° = 2,700°

That is the measure of the sum of the internal angles, and we have 17 of them, so the measure of each angle is:

2,700°/17 = 158.8°

Answer:

V=288π

288*3.14=904.32

Step-by-step explanation:

V=4/3π $(6)^{3}$

V=4/3π 216

V=4π72

V=288π

288*3.14=904.32

Data were collected from a typing class with 45 students. The class had an average of 56 words per minute (WPM) with a standard

STALIN [3.7K]

Answer:

Standard deviation gets smaller

Step-by-step explanation:

No. of students = 45

The class had an average of 56 words per minute (WPM) with a standard deviation of 7 WPM.

$Mean = \frac{\text{Sum of all observations}}{\text{No. of observations}}\\56=\frac{Sum}{45}\\56 \times 45=Sum\\2520=Sum$

The teacher realized that the data from one student who typed 55 WPM was not entered.

So, new sum = 2520+55

New sum =2575

So, new mean = $\frac{2575}{45}$

New mean =57.22

Standard deviation is the measure of distance between observation and mean

So, if number gets closer to mean , Standard deviation gets smaller . if the numbers get bigger , Standard deviation gets bigger.

Since 55 is closer to 57.22

So, Standard deviation gets smaller
