In selecting the sample size to estimate the population proportion p, if we have no knowledge of even the approximate values of the sample proportion p hat, we: a. take two more samples and find the average of their p hat
b. let p hat =0.05
c. take another sample and estimate p hat
d. let p hat =0.50
e. let p hat =0.95

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

50x5=$250

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
