Find the midpoint of the segment with the given endpoints. (2,9) and (-8,-8)

The midpoint is (-3, 1/2)

Step-by-step explanation:

To find the x coordinate of the midpoint, add the x coordinates of the endpoint and divide by 2

(2+-8)/2 = -6/2 = -3

To find the y coordinate of the midpoint, add the y coordinates of the endpoint and divide by 2

(9+-8)/2 = 1/2

The midpoint is (-3, 1/2)

ur answer to this question is (-3, 1/2)

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.
