Answer:
19 beers must be sampled.
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 Z-table as such z has a p-value of
.
That is z with a pvalue of
, so Z = 1.645.
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.
The population standard deviation for the temperature of beers found in Scooter's Tavern is 0.26 degrees.
This means that 
If we want to be 90% confident that the sample mean beer temperature is within 0.1 degrees of the true mean temperature, how many beers must we sample?
This is n for which M = 0.1. So






Rounding up:
19 beers must be sampled.
Answer:
6/5 x (x-6)
Step-by-step explanation:
convert the decimal into a fraction
1.2x -7.2
6/5x - 36/5
factor 6/5 from the expression
6/5x (x-6)
Answer:
1/2x
Step-by-step explanation:
Trust me bro lol
It is 830. ok just put the decimal in the back
