Jack plays basketball for 8 minutes and makes 14 points. If he plays for a total of 21 minutes, approximately how many points will Jack make?

x =36.75 points or approximately 37 points

Step-by-step explanation:

We can use a ratio to solve

8 minutes         21 minutes

=

14 points            x points

Using cross products

8x = 14*21

8x =294

Divide by 8

8x/8 = 294/8

x =36.75 points or approximately 37 points

b) 62.47% of the students are between 14 and 18 years old.

step-by-step explanation:

mean = 15 and standard deviation = 2

student between 14 to 18

formula used z-score

for age 14 , z score

using z-table , p(z> -0.5)=0.3085

for age 18 , z score

using z-table , p(z< 1.5)=0.9332

p(-0.5< z< 1.5)=0.9332-0.3085 = 0.6247

thus, 62.47% of the students are between 14 and 18 years old.
