Hello!
<h3><u><em>Answer</em></u></h3>
The mean of the numbers shown in the table is C. 50.5
<h3>__________________________________________________</h3><h3><em><u>Explanation</u></em></h3>
To calculate the mean, simply add up all the numbers and divide by the amount of numbers there are in the list.
18 + 55 + 101 + 96 + 55 + 18 + 22 + 23 + 22 + 57 + 88 = 555
There are 11 numbers in the table, so we divide by that.
555 / 11 = 50.45...
Finally, round to the nearest tenth: 50.5

Step-by-step explanation:
Using pythagoras theorem
Answer:14:8,21:12 , 28,16
Step-by-step explanation:
18 - 2H = 12 - .5H
Combine the variables
18 - 2H + .5H = 12 - .5H + .5H
18 - 1.5H = 12
Combine the whole numbers
18 - 18 - 1.5H = 12 - 18
-1.5H = -6
Divide by -1.5
-1.5H/-1.5 = -6 / -1.5
H = 4
The answer is 4 hours
