Is the data set approximately periodic? if so, what are its period and amplitude?

Option: c is the correct answer.

Periodic with a period of 4 and amplitude of about 25.

We are given a data set as:

Day             1      2       3     4      5      6     7      8      9      10     11     12

Books       102   78    91    140   98    74   88   137  100    75    92  139

borrowed

We divide the data set into three parts as follows:

1)

Day                            1           2            3         4

Books Borrowed     102        78          91       140

2)

Day                            5           6            7         8

Books Borrowed      98         74          88       137

3)

Day                            9           10          11        12

Books Borrowed     100         75          92      139

As we see that the values repeat approximately after every 4 values.

This means that the period of the data set is: 4

Also the amplitude of the data set is the average of difference between the  maximum value and the minimum value.

1)

Amplitude=(140-78)/2=31

2)

Amplitude=(137-74)/2=31.5

3)

Amplitude=(139-75)/2=32

The most approximate answer is:

Amplitude= 25

on your paper it doesn't say the answer but the the answer is altitude

step-by-step explanation:

answer: input the dimensions of the room to be painted. click the button to calculate the amount of paint and man-hours needed for this job.

interior paint coverage depends on the brand of paint used. the coverage amount is listed on the label of the paint can. use this to adjust the values in the paint coverage section below. paint usually is applied at 350 to 400 square feet per gallon (primer at 200 to 300 square feet per gallon).
