The five numbers summary for a data set is shown below. What is the range of the data set? 3, 7, 11, 14, 16
scoundrel [369]

Answer:

13

Step-by-step explanation:

The range of a set of data is the difference between the highest and lowest values in the set.

So, in order to find the range, you first order the data from least to greatest. Which it is already.

3, 7, 11, 14, 16

Then subtract the smallest value from the largest value in the set.

16 - 3 = 13

Hope this helps you out! : )

Gven the following table, find the rate of change between f(-4) and f(0) x -4 -2 0 2 4 f(x) -2 -1 0 1 2A. -2 B. 2 C. -1/2 D. 1/2
sweet [91]

Gven the following table, find the rate of change between f(-4) and f(0)



x -4 -2 0 2 4

f(x) -2 -1 0 1 2



A. -2

B. 2

C. -1/2

D. 1/2 ​

we know that

the rate of change is equal to

(f(b)-f(a))/(b-a)

f(b)=f(0)

f(a)=f(-4)

b=0

a=-4

(f(0)-f(-4))/(0+4)

we have that

f(0)=0

f(-4)=-2

substitute

(0+2)/4

2/4

1/2

therefore

<h2>the answer is the option D</h2>
