What is the equation, in point-slope form, of the line that is
parallel to the given line and passes through the point
(-1, - 1)?
Oy+1= -3(x+1)
Ov+1=-1/3(x+1)
oy+1=1/3(x+1)
oy+1=3(x+1)

12*c

step-by-step explanation:

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.
