The length of time it takes to fly from one place to another varies based on many factors. Given the following flight lengths, compute the average flight time, the range and the standard deviation in flight lengths. The flight lengths from Kansas City to Los Angeles are: 1 hr 40 min, 1 hr 45 min, 3 hr, 3 hr 35 min, 3 hr 20 min, 1 hr 45 min, 3 hr 15 min, 3 hr 25 min. Change all flight times to minutes.

answer:     true

step-by-step explanation:

question: how many people can she serve?

answer: she can serve 16.66666667 people. so she can only give 16 people a complete serving.

question: does she have enough ice cream for her guests?

answer: no. explanation: she only has enough for 16 people to have a full serving. however, she can give a 17th person a partial serving.

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
