Answer:
C
Step-by-step explanation:
THE THIRD CHOICE
The value of the 7 are
one of them is one hundred thousand
the other one is one hundred
To find the expected value of the distribution, we multiply each outcome by it's probability. Doing this, we get that the expected value of defects on a skateboard is of 
.
Outcomes and probabilities:
0 defects, 9/10 probability
1 defect, 1/20 probability
2 defects, 1/25 probability
3 defects, 1/100 probability.
Expected value:
Dividing both numerator and denominator by 4:
Thus, the expected value of defects on a skateboard is of .

Answer:
-7(a + 2b + 4)
Step-by-step explanation:
-7a - 14b - 28
⇒ -7(a + 2b + 4)
First you must plot one point on the y-axis. This point will be -5 because the y-intercept is a -5. Then you look at the slope. This is the number in front of the x. The numerator tells you how far up or down to go and the denominator tells you how far left or right to go. Because the slope is positive, we will go 2 points up from -5, and 3 points right from that. Plot your point. Then do the same thing from there. 2 up and 3 right and so on.
