Answer:

answer 13.33333 hours h

Step-by-step explanation:

Julia studied 3 1/3 hours during 4 days

this means she studied:

3 1/3 of 4 days of 24 hours

3 1/3 = 9/3 x 1/3 = 10/3

and 4 days of 24 hours is 4 x 24 = 96

there for

10/3 x 96 = (10/1)x32 =320 hours

320/24 hours each day -13.3333

Naddika [18.5K]

Answer:

9.6

Step-by-step explanation:

Plug in the knowns

a² + 22² = 24²

Subtract 22² from both sides

a² = 24² - 22²

a² = 576 - 484

a² = 92

Take the square root of both sides

Klio2033 [76]

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.
