Step-by-step explanation: 4*-60=-240. $-240 is the profit for the next 4 months. Add this to 450. 450+(-240)= 450-240=210. Next add the final month's profit. 210+125= 335.
Answer:
B. 97
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 M as such

In which
is the standard deviation of the population and n is the size of the sample.
How many students should be sampled to be within 1 drink of the population mean with 95% probability?
This is n when 
We know from preliminary studies that the standard deviation is around 5, so 





We round up, so the correct answer is:
B. 97
12*10^5 = 12*100000 = 1200000 ;
1200000 - 1000000 = 200000 ;
1.2*10^6 = 1.2*1000000 = 1200000;
1200000 - 1000000 = 200000;
Because 2000000 = 200000, neither of the two numbers is closer to 1 milion !
