Use the complement rule for probabilities

question

arces

over the course of a week, an airline has 42 flights between new york and los angeles. of these flights, 28 are considered

to be "on-time."

if you chose a particular flight at random, what is the probability that it would not be on-time? express your answer as a

fraction.

provide your answer below:

side side side

side angle angle

angle side angle

side angle side

step-by-step explanation:

the answer for this question is 38

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
