What is the slope of a line parallel to 5x — Зу = 18

slope =

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

5x - 3y = 18 ( subtract 5x from both sides )

- 3y = - 5x + 18 ( divide the terms by - 3 )

y = x - 6 ← in slope- intercept form

with slope m =

Parallel lines have equal slopes , then

slope of line parallel to 5x - 3y = 18 is m =

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.
