Step-by-step explanation:

Slope formula is Δy/Δx or (change in y)/ (change in x).

Apply that formula:

You know that 1-(-1) = 2, therefore for a slope of 1/5, the only possibile denominator is 10: 2/10 simplifies to 1/5.

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.
