Answer:

Mean = 9

Step-by-step explanation:

The mean is the average of a data set.  Given the values, 2, 9, 10, 12, 12:

Add all the numbers in the data set, and divide its sum by the number of items in the set:

Mean = \frac{2+9+10+12+12}{5} =  \frac{45}{5} = 9

Therefore, the mean of the given data set is 9.

What is a number between 364 and 384 that is a multiple of both 3 and 7
masya89 [10]

Answer:

378

Step-by-step explanation:

It will also be a multiple of 21 .

As it is divisible by 3  the first possibility is 366 so:-

364 + n = 21m

where n = 2,5,8,11,14...

Trying each number in turn we get:-

364 + 14 = 21m

21m = 378

m =  18

so the answer is 378
