Find the slope of each line.
1) y=9/5x+5 and
2)y=5

you!

Hello from MrBillDoesMath!

1) m = 9/5

2) m = 0

Discussion:  

1. y = (9/5)x + b follows the form "y = mx+b" so m = 9/5 for the first line

2. y = 5 is a horizontal line so m = 0

Thank you,

MrB

where is the image?

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.
