How do me find the mean of the data sets

To find the mean of a data set you have add all the values together and divide by the number of values in the set. The result is your mean

Step-by-step explanation:

Such as finding the mean of 1, 2, 4, 7, 9 as an example

Adding those numbers together you get 23. You then divide 23 by 5, given that there are 5 values above. 23/5 is 4.6. The mean would be 4.6

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.

the answer is 62.8 cubic units
