Answer:
C is your answer
Step-by-step explanation:
Mean is a form of average, and in order to find this we add up all the numbers then divide by the amount of numbers we have.
So, we have 5 numbers here. (8, 17, 9, 3, and 13)
8 + 17 + 9 + 3 + 13 = 50
50/5 = 10
The mean of those five numbers is 10.
Answer:
x = 15/8.
Step-by-step explanation:
Create an equation, let the number be x:
2/3 * x = 5/4
Now we multiply both sides by 3/2
3/2 * 2/3 x = 5/4 * 3/2
x = 15/8.
