Step-by-step explanation:
How to Find the Mean. The mean is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count. So for number 1# you would add all the numbers and divide by eleven so it should look like this
( 149 + 142 + 154 + 146 + 143 + 152 + 148 + 132 + 140 + 139 + 128 = 1573 ), since there is 11 numbers or boys you would divide by 11 which is 143.

Number 2# so the first five prime numbers are 5 prime numbers are 2, 3, 5, 7, and 11. So to find mean as I said before you would add all the numbers then divide by the total amount of numbers, so in this case there are 5 total numbers you would add them all then divide by 5. So in this case you would add 2 + 3 + 5 + 7 + 11 = 28 then you would divide 28 by 5 which is 5.6.

Number 3# so all you have to do is follow the steps to find mean again but your just gonna have to keep on trying different numbers until x makes sense.

Number 4# So for the last problem you would add all the temperatures which equals to 198.8 then you would divide it by 7.
