Suppose that it is reported in the news that 12% of the people living and working in Kokomo feel that their commute is too long. What is the travel time to work that separates the top 12% of people with the longest travel times and the lower 88%

22.3 minutes

Step-by-step explanation:

The computation of the travel time is as follows:

Given that

= 17

And, the standard deviation is 4.5

P(X≤C) = 0.88

P( x - ) ÷ ≤  (C - )  ÷  = 0.88

(C - )  ÷  = 1.175

c = +  1.175 ×

= 17 + 1.175 × 4.5

= 22.3 minutes

Hence, the travel time is 22.3 minutes

we know that

applying the law of sines

°

so

∠j=18°

∠k=29°

∠l=180-(18+29)=133°

the answer part a) is

the measure of angle k is  ≈29°

part b)  the measure of angle k could also be

(180-29)=151°

so

∠j=18°

∠k=151°

∠l=180-(18+151)=11°

the answer part b) is

the measure of angle k could also be 151°
