Use the sample information X=40, o-7, n-13 to calculate a 90 percent confidence interval for u assuming the sample is from a normal population.

answer: -2+√x,-2-√x

i hope this , i don't know if you're looking for a pair or not.

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
