If we want to be 95% confident of our estimate, does the sample proportion obtained, 20 out of 50, fall within the margin of error developed from the simulation? why or why not?

20/50 = 2/5 = 0.40 which is found in the dot plot given. Since this value is in the dot plot, this means that it is possible to obtain this value with a random simulation.

Yes, the sample proportion 20/50 falls within the margin of error.

triangle abc is reflected on the line x=-6.5 then reflected again on the x axis

step-by-step explanation:

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
