Answer:
9 / 40 or 0.225
Step-by-step explanation:
total marbles : 9 + 12 + 13 + 6 = 40 marbles
probability of taking red = total red marbles/ total number of marbles
probability of taking red = 9 / 40
Answer:
122 degrees
Step-by-step explanation:
<em><u>*A pentagon has a total of 540degrees </u></em>
1st step: take all of the degrees and add them up:
105 + 90 + 86 + 137 = 418
2nd step: subtract the sum from 540:
540 - 418 = 122
The missing angle is 122 degrees
Range = {-2(-2) - 5, -2(-1) - 5, -2(1) - 5, -2(2) - 5} = {4 - 5, 2 - 5, -2 - 5, -4 - 5} = (-1, -3, -7, -9}
-6*-13=78
-11*11=-121
6(-9)(-1)=-54
