In order to unload clay easily, the body of a dump truck must be elevated to at least 45°. The body of a dump truck that is 12 f
eet long has been raised to 8 feet. Will the clay pour out easily? Show your work and draw a diagram to support your answer
1 answer:
Assume that the angle is at the rear of the truck bed, and that the length of the truck bed is 12'. Then:
opp side
tan theta = --------------
adj side
becomes:
8 ft
tan theta = --------- = 2/3 = approx. 0.667
12 ft
Then tan theta = 2/3, and arctan (2/3) = 0.589 radian, or 33.7 degrees.
This is less than 45 deg, so the answer is NO, the clay will not pour out easily.

Answer:
a) P(X =16 ) = 0.1853
b) 
= 0.0684
Step-by-step explanation:
GIVEN DATA:
n = 16
p = 0.90
from relation given probabllity can be solve
a)
P(X =16 ) = 0.1853
b) 
= 1 - [ P(X = 13) +P(X = 14) +P(X = 15) +P(X = 16) ]
![= 1 - [ ^{16}C_{13} * 0.90^{13} * (1 - 0.90)^3 +^{16}C_{14} * 0.90^{14} * (1 - 0.90)^2 +^{16}C_{15} * 0.90^{15} * (1 - 0.90)^1 +^{16}C_{16} * 0.90^{16} * (1 - 0.90)^0 ]](https://tex.z-dn.net/?f=%3D%201%20-%20%5B%20%5E%7B16%7DC_%7B13%7D%20%2A%200.90%5E%7B13%7D%20%2A%20%281%20-%200.90%29%5E3%20%2B%5E%7B16%7DC_%7B14%7D%20%2A%200.90%5E%7B14%7D%20%2A%20%281%20-%200.90%29%5E2%20%2B%5E%7B16%7DC_%7B15%7D%20%2A%200.90%5E%7B15%7D%20%2A%20%281%20-%200.90%29%5E1%20%2B%5E%7B16%7DC_%7B16%7D%20%2A%200.90%5E%7B16%7D%20%2A%20%281%20-%200.90%29%5E0%20%5D)
