a. bethany made eight free throws for every 3 that she missed. Did bethany do better than richie? how do you know.

Answer 1

Answer:

Bethany did not do better than Richie because her average score was less than his.

Step-by-step explanation:

Average Value

The average or mean value of m successes out of n tries is given by:

$\displaystyle \bar x=\frac{m}{n}$

During a practice session playing basketball, Richie made m=12 free throws from n=15 attempts. His average score was:

$\displaystyle \bar x=\frac{12}{15}=0.8$

Bethany made 8 free throws for every 3 that she missed, this means she made 8 out of 11 attempts. Her average score was:

$\displaystyle \bar x=\frac{8}{11}=0.72$

Bethany did not do better than Richie because her average score was less than his.
