Step-by-step explanation:
Volume = Length times width times height.

This is equivalent to 84 3/8 cubic inches.
Ответ:
a. 84 students are predicted to practice everyday.
b. The sample size is 12.
Step-by-step explanation:
Given:
Total number of martial arts students at the school is 144.
Now, to find the students predicted to practice everyday.
Let the number of students predicted to practice everyday be
.
According to researching information 7 out of 12 martial artists practice every day.
So, 7 is equivalent to 12.
Thus,
is equivalent to ![144.](/tpl/images/0544/2725/293d8.png)
Now, to solve by using cross multiplication method:
By cross multiplying we get:
Dividing both sides by 12 we get:
Hence, it is predicted that 84 students practice everyday.
Now, to get the sample size:
Sample size is the researching information to observe of numbers to include in a statistical sample.
So, here 12 is the sample size.
Thus, a. 84 students are predicted to practice everyday.
b. the sample size is 12.
