What is the mean of data set 32 25 25 32 32 10 -10 25

Marat540 [252]

Answer:

21.375.

Step-by-step explanation:

The mean of an equation is the sum of all total numbers in the set divided by the total numbers in the set.

32 + 25 + 25 + 32 + 32 + 10 + -10 + 25 = 171.

171/8 = 21.375

Which of the following is equivalent to the complex number -8(7i - 3i^2)

Leni [432]

Answer: B) -56i - 24

This is the same as -24 - 56i

=============================================

Explanation:

The 'i' refers to the imaginary number $\sqrt{-1}$

In other words, $i = \sqrt{-1}$

Squaring both sides gets us $i^2 = -1$

So,

$x = -8(7i - 3i^2)\\\\x = -8(7i - 3(-1))\\\\x = -8(7i + 3)\\\\x = -8(7i) -8(3)\\\\x = -56i -24 \ \ \text{ .... Answer: Choice B}\\\\x = -24 - 56i\\\\$

The result is in the form a+bi where a = -24 is the real part and b = -56 is the imaginary part.
