Given the two points (-5,2) and (1,5) find the slope

Slope=1/2

Step-by-step explanation:

Slope=(y2-y1) /(x2-x1)

(-5,2)x1=-5, y1=2

(1,5)x2=1, y2=5

Slope=(5-2)/(1-(-5))

Slope=3/(1+5)

Slope=3/6

Slope=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.
