Please help! What is the slope of HI? Justify your answer.
Write a equation that represents line s.

slope of HI is -2

Step-by-step explanation:

so the line looks straight to me so just solve for the slope of D(8,32) E(12,24) which you solve with the equation y2 - y1/x2 - x1

so... 24 - 32 = -8 and 12 - 8 = 4

-8/4 = -2

I hope I helped you ;)

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.
