Answer:
13.1666666667 or 13.17
Step-by-step explanation:
The mean is the average of the numbers. So you should add 16, 12, 16, 8, 14, and 13. When you add all of these up, you get 79. Then, you divide 79 by the number of numbers there are. Since there are 6 cats, there are 6 numbers. 79 divided by 6 equals 13.1666666667. Now we round the number to the nearest tenth and we will get 13.17.

Answer:
Step-by-step explanation:
In the US, the most common eraser that is sold are the regular Pink Press erasers. These, as shown in the image below, are roughly 2.2 inches long. The most commonly used paper clip size is about 1.375 inches long. Assuming that these are the items that Dave is using to measure, then we can calculate the size of the calculator which is 2 erasers long...
2.2 + 2.2 = 4.4 inches long
The calculator is roughly 4.4 inches long, we can also divide this number by the length of the paper clip to find out how many paper clips make up the calculators length
4.4 / 1.375 = 3.2 paper clips
We are given the expression B=3Mn/2 and told to express M in terms of B and n. This means that we should apply mathematical operations on both sides of the equation so we "isolate " M on one side of the equality sign. We begin with the given equation

First, we multiply both sides by 2, so we get

Next, we divide by 3 on both sides, so we get

Finally, we divide both sides by n, so we get

In this case, we have succesfully expressed M in terms of B and n
