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

d

step-by-step explanation:

hello and welcome!

so, when we see the words "proportional" along with a table, we need to know that we're looking numbers that divide by the same thing.

looking at this table, we simply have to do a trial and error, and divide to see which numbers have the same quotient. if you look at choice a & c, they both have equal quotients for three of the numbers, with one exception, so those can't be the answer. looking at b, there is no similarity, so that can't be it. then, we see d; if you divide all the numbers in the table, you'll see that they all divide by two, which is a proportional relationship, and our answer!

also, always remember that the x will always be the number that goes into y, and somewhere behind this table, is a formula. for this specific table, the formula would be:

since our x-value is being divided by two to get the y-value. and if they were to ask for more numbers in the series, this is the formula you would use to find them.
