Answer:
The models have tiles corresponding to x+8 and x+1
Step-by-step explanation:
We want to find the model that represents factors of

We split the middle term to get:

We factor by grouping to obtain:

We collect common factors again to get:

The models have tiles corresponding to x+8 and x+1
Using it's concept, it is found that there is a 0.125 = 12.5% experimental probability that a randomly selected preschooler would choose to read books today.
<h3>What is a probability?</h3>
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
For an experimental probability, these numbers of outcomes are taken from previous trials.
In this problem, in the previous trial, one out of eight students read a book, hence:
p = 1/8 = 0.125 = 12.5%.
There is a 0.125 = 12.5% experimental probability that a randomly selected preschooler would choose to read books today.
