A researcher center poll showed that 79% of people believe that it is morally wrong to not report all income on tax returns. What is the probability that someone does not have this belief?

21%

Step-by-step explanation:

The total people polled was 100% or 1 in decimals and 79% or 0.79 of people have this belief.  It follows that 100%-79%=21% of people don't share that belief.

you probably already have the answer but anyways it's b. 15.0

step-by-step explanation:

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)
