Step-by-step explanation:
7 x -6 = 42
Answer:
Greatest common factor of 17
So, the prime factors of 45 are 3, 3, and 5. The Greatest Common Factor is the greatest number that is common (that is, in both lists). It is 17. Since 17 is a factor of itself and of 51 -- which is 3 x 17 -- then the greatest possible common factor is 17!
Step-by-step explanation:
Add and subtract the second term to the expression and factor by grouping.
- (m - 1 )( 7m + 17 )

Answer:
The margin of error for a confidence interval for the population mean with a 90% confidence level is 0.53 hours.
Step-by-step explanation:
We have that to find our
level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of
.
So it is z with a pvalue of
, so
Now, find the margin of error M as such
In which
is the standard deviation of the population and n is the size of the sample.
In this quesstion:

So
The margin of error for a confidence interval for the population mean with a 90% confidence level is 0.53 hours.
