What is the mean absolute deviation
4 2 2
of the following set of data?
10

mean absolute deviation would be 2.75

Step-by-step explanation:

mean: 4 + 2 + 2 + 10 = 18/4 = 4.5

4.5 - 4 = 0.5

4.5 - 2 = 2.5

4.5 - 2 = 2.5

4.5 - 10 = 5.5

mean absolute deviation: 0.5 + 2.5 + 2.5 + 5.5 = 11/4 = 2.75

~hope this helps~

please mark me the brainliest, I would highly appreciate it :)

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.
