Samantha is trying to complete the free throw wellness challenge. in order to earn her chip, she needs to hit 13 out of 20 free throws on the basketball court her last three attempts were 12 out of 20, 10 out of 20, and 9 out of 20 how far is her average free throw percentage from the needed free throw percentage to earn the chip? (round to the nearest whole number)

21 % below what she needs

Step-by-step explanation:

She had hit 12, 10 and 9

This averages to

(12+10+9)/3 = 31/3 =10 1/3

She needs 13

Percentage = (needed-actual)/needed * 100%

                    = (13-10 1/3) / 13 * 100%

                    = (2 2/3) /13 * 100%

                    =.205128205 * 100%

                   =20.5128205%

To the nearest whole number

                      21 %

She is 21 % below what she needs
