Answer:

Step-by-step explanation:

Because in equation x-9y=12

If we put x=12 and y=0 then it satisfy equation. (12)-9(0)=12

So, (12,0) make equation

(3,-1) also make equation

(3)-9(-1)=12

(0,-4/3) also make equation

Because

0-9(-4/3)=12

Only (0,12) is not making

Beacuse

(0)-9(12) is not equal to 12

Hi! The temperature would be 18°.

There was a 4 hour period between 5 and 9 a.m.

So, I just took -10, and added 7 four times.

-10 + 7 + 7 + 7 + 7 = 18

Hope this helps you! Happy thanksgiving, here's a turkey!

Step-by-step explanation:

The Central Limit Theorem estabilishes that, for a random variable X, with mean $\mu$ and standard deviation $\sigma$ , the sample means with size n of at least 30 can be approximated to a normal distribution with mean $\mu$ and standard deviation $s = \frac{\sigma}{\sqrt{n}}$
