nadya68 [22]

There is 4.88% decrease in Olivia's score.

Step-by-step explanation:

Given,

Score on first math test = Old value = 82 points

Score on second math test = New value = 78 points

Change = New value - Old value

Change = 78 - 82 = -4

The negative sign indicates the decrease.

Decrease percent = $\frac{Change}{Old\ value}*100$

Decrease percent = $\frac{4}{82}*100=\frac{400}{82}$

Decrease percent = 4.88%

There is 4.88% decrease in Olivia's score.

saul85 [17]

Answer:

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

<h3>How to arrive at the generalization.</h3>

More of the shoppers are said to select an apple from the group of shoppers who are to but either banana or apple.

Those buying an apple are two times the people buying the banana, hence we can conclude that twice as many shoppers would choose the apple over banana.
