Part 1 Lines m and n are perpendicular. If the slope of line m is zero, then what is the slope of line n? If you were to sketch lines m and n, what type of lines would you sketch? Part 2 On a graph, create your own set of perpendicular lines similar to lines m and n. Choose two points on each line and prove through the slope formula, that the lines are perpendicular to each other.

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.

step-by-step explanation:

26 is 33.33% of 78

step-by-step explanation:

26 is what percent of 78?

26 is p% of 78

equation: y = p% * x

solving our equation for p

p% = y/x

p% = 26/78

p = 0.3333

convert decimal to percent:

p% = 0.3333 * 100 = 33.33%

you can not solvr this without numbers
