Answer:
18/20 or 9/10
Step-by-step explanation:
The list shows the amount of hours each student USED the computer.
Wherever we see a "0", that means he/she DID NOT USE computer.
There are 2 "zeroes", so 2 didnt use out of 20, so number of student who DID USE is 20 - 2 = 18
To find ratio of total number of students who used to the total number surveyed, it is going to be:
18/20 or 9/10
<h3>
Answer: 5</h3>
===============================================
Explanation:
Look at the entries of each table when x = 2
For p(x), we have p(x) = 3 when x = 2
For q(x), we have q(x) = -2 when x = 2
Both of these are the second row of each table.
---------
Subtract these function output values mentioned
3 minus -2 = 3 - (-2) = 3 + 2 = 5
Note how the two negatives cancel to make a positive. Subtracting a negative is the same as adding.
