Apaint manufacturer made a modification to a paint to speed up its drying time. independent simple random samples of 11 cans of type a (the original paint) and 9 cans of type b (the modified paint) were selected and applied to similar surfaces. the drying times, in hours, were recorded. the summary statistics are as follows.

78.59 is the mean

step-by-step explanation:

$5.41

step-by-step explanation:

$20 - $14.51 = $5.49.

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
