  1/5

Step-by-step explanation:

The slope is given by the slope formula:

  m = (y2 -y1)/(x2 -x1)

Using the first two points in the table, we have ...

  m = (-2 -(-3))/(1 -(-4))

  m = 1/5

The slope is 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.
