Answer:
f(g(2)) = 1
Step-by-step explanation:
Another way to write this composite is f(g(2)). We first have to compute g(2), then fit that value into f.
.
g(2) = 4. Now we have to find f(4):
f(4) = 4 - 3 = 1
2 out of 5 chance that you will attests get 3
-108x(x-3) I’m pretty sure
I’m guessing C
(It’s probably wrong, I just need points)
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.
