You have a statistics project due in your math class. as part of the project for one hour you count how many shoppers at your favorite store are between the ages of 21 and 25. your frequency table is below. use this table to answer (a-c)
ages. frequency
21, 22,23,24,25 2,5,3,7,10

a) find the mean of the data.
b) find the standard deviation of the data.
c) explain what the mean and standard deviation tell you about the data you collected.

the answer would be c:   ax + b = ax + c

step-by-step explanation:

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have

168

step-by-step explanation:

first off, we know that he drove 3.5 hours at a rate of 48 mph.

knowing that, we want to see how many miles he drove all-together.

in this case, we can just multiply 48 by 3.5.

48 * 3.5 = 168

38.6°

step-by-step explanation:

resultant is 10 pound

smaller force = 8 pound

angle formed = tan⁻¹(

                        =tan⁻¹(

                          =tan⁻¹(0.8)

                        =38.6°
