The <u>correct answer</u> is:

1/4, or 25%.

Explanation:

The relative frequency is the fraction of times something occurs compared to the total.

In this problem, 15 out of 60 participants are in this range.  This is written as:
15/60.

This will then simplify:
15/60 = 1/4 = 0.25 = 25%

The frequency is how often something occurs. Here 15. It occurred 15 times that the participants scored in the interval given.

The relative frequency (expressed as a percent) looks at how often something occurred relative to the overall occurrences. Here 15/60 = 1/4 = 25%

The relative frequency is 25%

A student says that a coordinate grid under a dilation with the center at the origin and scale factor 2 does not change the grid
Kisachek [45]

Answer:

Dilation changes (x,y) values not the grid or coordinate plane. Basically, dilating a graph or a coordinate grid means the original coordinates you may have had will be changed with the dilation.  For example, a triangle plotted had its original area of 26 dilated to an area of 58.

PLEASE HELP ASAP f(x) = x2 What is g(x)?
vfiekz [6]

Answer:

c. g(x) = 4x^2

Step-by-step explanation:

From a first glance, since g(x), is skinnier than f(x), meaning that it is increasing faster, so I know that I can eliminate options A & B since the coefficient on x needs to be greater than 1.

We can then look and see that g(1) = 4 as shown by the point given to us on the graph.

To find the right answer we can find g(1) for options C & D and whichever one matches the point on the graph is our correct answer. e

Option C:

once we plug in 1 for x, our equation looks like

4(1)^2.

1^2 = 1, and 4(1) = 4,

so g(1) = 4. and our point is (1,4).

This is the same as the graph so this is the CORRECT answer.

If you want to double check, you can still find g(1) for option D and verify that it is the WRONG answer.

Option D:

once we plug in 1 for x, our equation looks like

16(1)^2

1^2 = 1, and 16(1) = 16,

so g(1) = 16. and our point is (1,16).

This is different than the graph so this is the WRONG answer.

What are the domain and range of f(x) = 2x - 41?
Darina [25.2K]

The domain of the function is a (-∞, 0) and the range of the function will be f(x) < 0. Then the correct option is C.

<h3>What are domain and range?</h3>

The domain means all the possible values of x and the range means all the possible values of y.

The function is given below.

f(x) = 2x – 41

Then the domain of the function is a (-∞, 0) and the range of the function will be f(x) < 0.

Then the correct option is C.

More about the domain and range link is given below.
