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:
1/4 of 72 subtracted from 16 is 2 times 1/8 of 8
Step-by-step explanation:
1/4 of 72 is 18. Subtract by doing 18-16 to get 2. 1/8 of 8 is just 1, so 2 times 1 is 2, which is the same number when you subtract 16 from 18.
Hope this isn't confusing comment if there are any questions
Answer:
to be parallel
slope should be equal
for first question
y=1/3X +2
comparing with y=m1x+c
slope = 1/3
similarly for second equation
y=1/3x -4
comparing with y=m2x + c
m2= 1/3
since m1=m2
lines are parallel
150/3 = 50 miles/hr
So 400/50 = 8 hr
The answer is 8 hours.
The answer is- H) y = 5x + 17
