To find the midpoint of a segment on the coordinate plane, you find the averages of the endpoints.
A. True
B. False

A.True

Step-by-step explanation:

To find the midpoint of a line  segment, we find the averages/mean of the endpoints of the line segment.

Midpoint Formula:

M(x,y)=(x₁+x₂/2 , y₁+y₂/2)

hello,

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.
