20. Mackenzie has made 21 of her last 30 free throws which is an average of 70%. A. Write a function to model Mackenzie's rate of success if she makes x more
consecutive free throws.

 Either 70% or S=0.7x

Step-by-step explanation:

I'm unclear as to what the question really wants.  A "rate of success" is simply an expected percentage of future shots that will score on a free throw.  Since the only statistic we are given is the 70%, it would seem that would also be the rate of success for future shots.

If the question is seeking the actual number of successful free throws, S, in the next x shots, the expression would be:

S = 0.70x

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b
