Inga, Kai, and Jason volunteer in the school library. They want to find the average number of pages of a library book. It would

be unreasonable to calculate the number of pages in every book to find the average. They decide they need to find a valid sample.
Inga suggests choosing 100 books from the history section to get a sample.

Kai suggests randomly selecting 100 books from the library’s entire catalog.

Jason suggests using 100 books from the teen fiction section to get a sample.

Who suggested the best way to produce a random sample that is not biased?

Kai did bc it is from the libraries entire catalog so it could be any genre so it would produce an unbiased sample :)

Can you check my work? I need a little bit of help >.>
dangina [55]
So, 14 sentences per minute = 840 sentences per hour (60 minutes in an hour, 14(60)=840)

If 17 pages have 120 sentences on each page, we can conclude that there are a total of 2040 sentences that remain (17x120=2040)

If Jolie can read 840 sentences per hour, we can divide 2040/840 (total # of sentences left divided by sentences per hour)

2040/840 = 2.43 hours.

Find the average rate of change of f(x)=2x-1 from x=-1 to x=2
MrMuchimi

The average rate of change from x = -1 to x = 2 is 2

<u>Solution:</u>

Given function is:

f(x) = 2x - 1

We have to find the average rate of change from x = -1 to x = 2

<em><u>The average rate of change is given as:</u></em>

\text {Average rate of change}=\frac{f(b)-f(a)}{b-a}

<em><u>The average rate of change from x = -1 to x = 2 is given by formula:</u></em>

\text {Average rate of change}=\frac{f(2)-f(-1)}{2-(-1)}\\\\\text {Average rate of change}=\frac{f(2)-f(-1)}{3}

<em><u>Find f(2) and f( - 1)</u></em>

<em><u>Substitute x = 2 in given function</u></em>

f(2) = 2(2) - 1 = 4 - 1 = 3

<em><u>Substitute x = -1 in given function</u></em>

f( - 1) = 2(-1) - 1 = -2 - 1 = -3

<em><u>Substitute the values in above formula,</u></em>

\text {Average rate of change}=\frac{3-(-3)}{3}=\frac{6}{3}=2

Thus average rate of change from x = -1 to x = 2 is 2
