The data represent the number of phone calls received over an 8-day period.

day 1 2 3 4 5 6 7 8
calls received 5 3 8 7 9 9 10 9

what is the mean number of calls received per day?

The mean number of calls received per day is:

7.5

Step-by-step explanation:

Day                        12345678

Calls Received 538799109

Mean number of calls received per day is calculated as sum of the call received each day over number of days

i.e. Mean =(5+3+8+7+9+9+10+9)/8

               = 7.5

Hence, the mean number of calls received per day is:

7.5

75

step-by-step explanation:

you do x-29=46 (the number of cantaloupes sold)

in order to find x, you have to find what minus 29 equals 46, meaning you'd have to add 29 to 46.

29+46=75

if you replace x with 75, the equation looks like:

75-29=46

x=75
