The taxi and takeoff time for commercial jets is a random variable x with a mean of 9 minutes and a standard deviation of 2.6 minutes. assume that the distribution of taxi and takeoff times is approximately normal. you may assume that the jets are lined up on a runway so that one taxies and takes off immediately after the other, and that they take off one at a time on a given runway.(a) what is the probability that for 37 jets on a given runway, total taxi and takeoff time will be less than 320 minutes? (round your answer to four decimal ) what is the probability that for 37 jets on a given runway, total taxi and takeoff time will be more than 275 minutes? (round your answer to four decimal ) what is the probability that for 37 jets on a given runway, total taxi and takeoff time will be between 275 and 320 minutes? (round your answer to four decimal places.)

the correct answer is you spend $55.78 more in a brand store that buy ing in a normal store.

step-by-step explanation:

brand = spend   $ 135.85 total

store = spend $80.07 total

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
