Hey there!
2 + 1.25f = 10 - 2.75f
Add 2.75f to both sides.
1.25f + 2.75f = 4f
4f + 2 = 10
Subtract 2 from both sides.
4f = 8
Divide both sides by 4 to solve for f.
f = 2
I hope this helps!
S= 15
3s=45
3s/3=45/3
S=15
You have to divide both sides

Answer:
At least 547 records need to be studied.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of 
, and a confidence interval 
, we have the following confidence interval of proportions.
In which
Z is the zscore that has a pvalue of 
.
And the margin of error is:
95% confidence interval
So 
, z is the value of Z that has a pvalue of 
, so 
.
In this problem, we have that:
At least 547 records need to be studied.
