Answer:
8
Step-by-step explanation:
Use substitution: substitute each number from the set in for x, and see if the result from dividing is 45.
4
360/x=45
360/4=90
90 ≠ 45
Therefore, 4 does not make the equation true
8
360/x=45
360/8=45
45=45
Therefore, 8 does make the equation true.
16
360/x=45
360/16=22.5
22.5 ≠ 45
Therefore, 16 does not make the equation true.
So, 8 is the value that makes the equation true
Answer:
The probability that the machine will dispense at most 8.8 liters is 0.60
Step-by-step explanation:
A uniform distribution, also called a rectangular distribution, is a probability distribution that has constant probability.
The distribution is given by:
f(x)={
⇒A≤x≤B; 0 ⇒ elsewhere}
Hence,
P(x≤8.8)=![\int\limits^{8.8}_7 {\frac{1}{B-A} } \, dx =\int\limits^{8.8}_7 {\frac{1}{10-7} } \, dx =\int\limits^{8.8}_7 {\frac{1}{3} } \, dx=\frac{1}{3}(8.8-7)=\frac{1}{3}(1.8)=0.6](https://tex.z-dn.net/?f=%5Cint%5Climits%5E%7B8.8%7D_7%20%7B%5Cfrac%7B1%7D%7BB-A%7D%20%7D%20%5C%2C%20dx%20%3D%5Cint%5Climits%5E%7B8.8%7D_7%20%7B%5Cfrac%7B1%7D%7B10-7%7D%20%7D%20%5C%2C%20dx%20%3D%5Cint%5Climits%5E%7B8.8%7D_7%20%7B%5Cfrac%7B1%7D%7B3%7D%20%7D%20%5C%2C%20dx%3D%5Cfrac%7B1%7D%7B3%7D%288.8-7%29%3D%5Cfrac%7B1%7D%7B3%7D%281.8%29%3D0.6)
The probability that the machine will dispense at most 8.8 liters is 0.60
