To find the percentage always multiply whatever decimal number you have by 100% <span>
1) 5 + 8 + 12 = 25 (total number in bag)
5/25 x 100% (because you're trying to find probability of red)
= 20%
2) 5 + 8 = 13 (# of red AND blue)
13/25 x 100% (divide out of the total)
=52%
3) 5/25 = 0.2 x 12/25 = 0.48 (find probability of drawing red and green)
0.2 x 0.48 x 100%
= 9.6%
4) 10 + 12 + 28 = 50 (to find total number of trials)
28/50 x 100%
= 56%
5) 5 x 7 (number of sections on first spinner multiply by # of sections on second spinner)
= 35</span><span>Its B 20%

Hey Kat! :)
Glad to see you on Brainly.
Look below and watch how we solve this problem.
Ask any questions if you need it! I'll respond when you need it!
This is a bit of a hard, one. So please ask questions.
------
Please use the rule a/b x c/d = ac/bd while solving.
After using that equation, it should look like this:
2 x -5 x -3 / 7 x -8
Simplify 2 x -5 to -10.
Now, it should look like -10 x -3 / 7 x -8
30/7 x -8
30/-56
- 30/56 (the negative is front of the WHOLE equation.)
-15/28 is our final answer.

Answer: Choice A) -10.73</h3>
Work Shown:
Plug x = 4.3 into the equation given
ŷ = 2.6 − 3.1x
ŷ = 2.6 − 3.1(4.3)
ŷ = 2.6 − 13.33
ŷ = -10.73
Note: The symbol ŷ is read as "y hat". It's used to estimate the y value when it comes to regression equations.
