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:
Option B. 16-8
Step-by-step explanation:
Let
z ------> the number of apple left
x -----> the total number of apples
y -----> the number of apples sold
we know that
The numerical expression of the phrase " the number of apples left if eight out of the sixteen apples have been sold" is equal to subtract the number of apples sold from the total number of apples
so
z=x-y
we have
x=16 apples
y=8 apples
substitute
z=16-8
It should be 8 people.
16% of 100 people is 16 people.
16+28+48=92
100-92= 8 people
Answer:
60 -047 = 13 in²
Step-by-step explanation:
Paper area: 6 x 10 = 60
15 circles, each circle has diameter: 6 /3 or 10 /5 = 2
each circle area: πr² = 3.14 x 1² = 3.14
15 circles: 3.14 x 15 = 47.1
paper wasted: 60 - 47.1 ≈ 13 in²
