a. (y+4)=-1/3 (x+1)

b. (y-1) = -1/3 (x-2)

c. (y-4) = -5/3 (x-1)

d. (y+4) = 5/3 (x+1)

point a is the center of this circle.

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.
