Find the mean of the list of data.<br> 49, 65, 41, 38, 87, 55, 95, 106<br> I can’t find the answer

KatRina [158]

Answer:

67.

Step-by-step explanation:

First we find the mean:

Mean is add up everything and divide by how much numbers there are.

The numbers are:

$49, 65, 41, 38, 87, 55, 95, 106$ .

So we add them up which is 536.

Then we divide by how much numbers there are.

There are 8 numbers so 536/8 which is 67.

Hope this helps :D

Paraphin [41]

Answer: (x - 3)² = 21

<u>Step-by-step explanation:</u>

x² - 6x + ____ = 12 + ____

↓ ↑ ↑

$\frac{-6}{2} = (-3)^{2}$

x² - 6x + <u> 9 </u> = 12 + <u> 9 </u>

(x - 3)² = 21

Answer: (x - 6)² = 26

<u>Step-by-step explanation:</u>

2x² - 24x = -20

<u>÷2 </u> <u> ÷2 </u> <u> ÷2 </u>

x² - 12x = -10

x² - 12x + ____ = -10 + ____

↓ ↑ ↑

$\frac{-12}{2} = (-6)^{2}$

x² - 12x + <u> 36 </u> = -10 + <u> 36 </u>
