Answer:
x = 19
Step-by-step explanation:
Assuming all angle measures are in degrees, the sum of them is 180:
(3x +16) +(4x -15) +(2x +8) = 180
9x +9 = 180 . . . . collect terms
x + 1 = 20 . . . . . . divide by 9
x = 19 . . . . . . . . . .subtract 1
The value of x is 19.
Answer:
108
Step-by-step explanation:
12x9=108
108/9 = 12
Answer: 466.56
Step-by-step explanation:
Volume = pi times radius^2 times height/3
Radius = 1/2 of the diameter
Volume = 3.24 times 6^2 times 12/3
Volume = 3.24 times 36 times 4
Volume = 116.64 times 4
Volume = 466.56
Answer:
I don't know, because i really don't know
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
.
