Roger restores vintage automobiles. The number of automobiles Roger has restored, f, after n number of years can be described by the equation f(n)=2+5n. What is the rate of change in this situation?

The change of rate of the situation is 5.

Step-by-step explanation:

Given f(n) = 2 + 5n. The rate of change is still the same as the slope of the equation. We know that the equation of a line is given as:

f(x) = y = mx + c where m is the slope. In our given equation, f(n) = 2 + 5n = 5n + 2, we see that m = 5 which is our slope.

Therefore, the change of rate of the situation is 5.

answer

a) the midrange of the data set shown is 85.5

step by step explanation

let's find the midrange.

the midrange is nothing but add the greatest value and the least value, then divide it by 2.

here the greatest value = 99

the least value = 72

midrange = (99 + 72)/2

= 171/2

midrange = 85.5
