Answer:
1. 2,2
2. 1,1,3,3,5,5,7,7,9,9
3. 0,0,1,1,2,2,3,3
Step-by-step explanation:
The possible outcomes are: 0,0,1,1,2,2,3,3,4,4,5,5,6,6,7,7,8,8,9.9
There are 20 possible outcomes
2. There are 1,3,5,7,9 = 10 non even numbers
1,1,3,3,5,5,7,7,9,9
3. There are 0,1,2,3 = 8 numbers less than 4
0,0,1,1,2,2,3,3
80 * 80% = 64 So it's not A
80 * 55% = 44 so it's not B
80 * 100% = 80 so it's not C
80 * 125% = 100 so D is your answer
<u>Step 1:</u>
<u>Step 2:</u>
<u>Step 3:</u>
<u>Final Solution:</u>
-50
-12 + (-38) can also be written as -12-38, and that would be -50
Means to write a product with A as a factor B times
