Answer:
okay so the first question says divide :40203 by 13
= after dividing the quotient comes as 3092
Step-by-step explanation:
then to verify the answer using division algorithm
the formula is as dividend = (q x d) + remainder
so the verification= 13 x 3092 + 7 = 4023
the second question says to find the difference between the pv of two 4's in 948475
the answer is 40000 - 400 = 39600ans.
the third question's answer will be:

Answer:
A sample size of 554 is needed.
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 
.
That is z with a pvalue of 
, so Z = 1.96.
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.
Standard deviation is known to be $12,000
This means that 
What sample size do you need to have a margin of error equal to $1000, with 95% confidence?
This is n for which M = 1000. So
Dividing both sides by 1000:
Rounding up:
A sample size of 554 is needed.
X=50 because 16 × 156.25 is 2500, then decided by 50 is 50
