You can obtain information about the mean population by taking a random sample of it and taking the average of that sample. The Law of big Numbers says that the bigger the sample, the more likely we will be closer to the real mean value. In other words, the margin of error is less likely to be big.

Find each product.<br><br> (5-x2+2)(-3)<br><br> PLEASE HELP!!! ASAP!!!
Bumek [7]

Answer:

3x^2 - 21 (did you mean for the equation to be (5 - x^2 + 2) \cdot -3?)

Step-by-step explanation:

Multiplying -3 by each term:

-3 \cdot 5 = -15

-x^2 \cdot -3 = 3x^2

-3 \cdot 2 = -6

-15-6 = -21

So the equation comes out to 3x^2 - 21 .

Hope this helped!
