Surveys conducted in american high schools concluded that 90% of the students in a sample of 400 students had more than one active email
account. what would the margin of error be for the population proportion?

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571

step-by-step explanation:

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval

- (2, -7)

- lines r and s and lines t and u must be parallel

step-by-step explanation:

*calories burned = (weight)(calorie factor)*

calories burned = 180 (0.65)

calories burned = 117

the calories he used up is 117, which is 65% of his weight.
