For the graphed function f(x) = −(5)x − 3 + 2, calculate the average rate of change from x = 3 to x = 4.
azamat

Answer:

-4 is the average rate of change from 3 to 4

Step-by-step explanation:

Average rate of change is defined as the fraction of change in f(x) value to change in x value.

Here we have x values as 3 and 4.

To find the average rate of change from x=3 to x=4

Average rate of change = change in f(x)/change in x

f(4) = -5^{4-3} +2 = -3\\f(3) = 1\\f(4)-f(3) = -3-1 =-4

Change in x = 4-3 =1

Jennifer has 25 books on her bookshelf. She has 10 fiction books, and the rest are non-fiction books. If Jennifer selects a game
saul85 [17]

Answer:

<h2>3/5</h2>

Step-by-step explanation:

If Jennifer has 25 books on her bookshelf and she has 10 fiction books, the number of non-fiction books she has will be 25-10 = 15 non- fiction books.

Probability is the likelihood or chance that an event will occur.

Probability = Expected outcome of event/total outcome.

Since we want the expression that represents the probability that the book she selects will be a non-fiction book, our expected outcome will be 15(the total non fiction she selected)

The total outcome will be the total number of books i.e 25.

Probability that she elects non fiction book = 15/25

= 3/5
