At a university, the probability that an incoming freshman will graduate within four years is 0.654. What is the probability that at least 70 out of a group of 110 incoming freshman will graduate in four years?

idk

step-by-step explanation:

use that smart brain

let y equal to

the total fare and x is the mile of taxi ride. so the equation is

y = 0.55x + 1.75

since susie has

$10 to spend for a taxi cab, so he can have

10 = 0.55x +

1.75

x = 15 miles of

taxi ride

so the system of

inequality is

10 < 0.55x +

1.75

x > 2

you estimate that the angle of elevation to the top of the 86th floor (the observatory) is 82 .the total height of the building is another 123 meters above the 86th floor.

leave feedback if u need : )
