Find the mean of the following data set. 42, 45, 58, 63 42 47 52

You have to add all the numbers and then with that sum divide it by the number of numbers. In this case it would be 42+45+58+63+42+47+52=349. Now divide that by the numbers of numbers which in this case is 7, ~49.85(answer).

Well if you have 20 bats you probably want 20 balls? you don’t have enough context to answer the question.

The answer simplified would be. -6300x
