Answer:
53x - 4 = 30
53x = 30 +4
53x = 34
x= 34/53

Answer:
The probability that a site has no problem when the machine says that the pipe at the site has no issue is
0.905
Step-by-step explanation:
Confidence level = 95%
Error level = 5% (1 - 95%)
Since the probability that the machine says the pipe has a problem for a site that in fact has an issue = 95% and the pipe has a problem in 10% of the case, this means that the pipe has a problem in exactly 0.095 (10% * 95%).
Therefore, the probability that a site has no problem when the machine says that the pipe at the site has no issue = 0.905 (1 - 0.095).
Answer:
108 square feet
Step-by-step explanation:
This question is essentially asking us for the area. (Don't be fooled into thinking this is a perimeter question. Imagine if you had a floor with just a ring of carpet on the edges!)
Let's separate this into areas we can understand. The square to the right, with dimensions 6 ft by 6ft, has an area of
A = s*s = 6*6 = 36 square feet
The rectangle that we have left has dimensions 12 ft by 6 ft, so it has an area of
A = l*w = 12*6 = 72 square feet
Add those together to get the total area.
A(rect) + A(square) = 72 + 36 = <u>108 square feet</u>
