The rates of on-time flights for commercial jets are continuously tracked by the u. s. department of transportation. recently, southwest air had the best reate with 80 % of its flights arriving on time. a test is conducted by randomly selecting 10 southwest flights and observing whether they arrive on time. find the probability that at least 9 flights arrive late.

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

answer: 60%

explanation:

÷

= 60%
