Uri asked six friends how many different foreign countries they’d been to. he recorded 0, 1, 1, 2, 5, and 9 countries visited. what is the mean absolute deviation of countries visited? round to the nearest tenth, if needed.

 there is mean absolute deviation of countries is 2.7 countries

Step-by-step explanation:

since we have given that

0, 1, 1, 2, 5, and 9 countries visited.

so, Mean of all countries visited is given by

We have to calculate the mean absolute deviation of countries visited.

So, we know the formula:

Hence, there is mean absolute deviation of countries is 2.7 countries.

2.7 countries

Step-by-step explanation:

I did the test

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)
