Answer:
It equals 3, but if you add two negatives inside of the parenthesis, then it equals -19.
Step-by-step explanation:
You have to plug in the numbers where the variables are, so it would be -8-(-11).

Simple probability is found by counting all the results which fit requirements and dividing by all possible results.
To find probability of two results in a row, multiply chance of first result by chance of second result.
Since you are replacing the marble before the second draw, we don’t have to figure out the various changes in odds for the different possible first draws. It’s just that simple.
There are 5 white marbles
There are 4 red marbles
There are always 20 marbles in all
5/20*4/20=1/4*1/5=1/20 or 1/2
By coincidence, the same as the chance of drawing the white marble in one draw.
Absolute value describes how far away a number is from 0
The absolute value of a number is always positive even if you are looking at the absolute value of a negative number.
Examples
The absolute value of 6 = 6
The absolute value of -6 = 6
Answer:(a+b)^4
Step-by-step explanation:
You first see what they both have in common. In this case it is the the 4 squared. You then take that out and you see what is left. The thing that is left is a+b.
So you put the a+b inside the parentheses and the 4 squared outside.
so your answer will be (a+b)^4.
Hope this helped.
