Based on the error rate of manually and electronically filed returns, the chances of making an error using manual instead of electronic is c. 400 times more likely.
<h3>How much more likely are errors with manual filing?</h3>
This can be found as:
= Percentage error from manual returns / Percentage error from electronic returns
Solving gives:
= 20% / 0.05%
= 400 times
In conclusion, option C is correct.

Answer:
After taking the first exam, 15 of the students dropped the class. The value 15 describes a characteristic of a population - first choice.
Answer:
45
Step-by-step explanation:
50% is equal to 0.5
Multiply 90 by 0.5 to get your answer:
90 × 0.5 = 45
The answer is : f(x) =3sin(2x+pi/2)
Explain
There 0,3 on the graph
You use this formula
f(x)=asin(kx-c)+h
and the maximum and minimum value of this function
a+ h and -a+ h
So a=3 and h=0
So we have
We have; f(x)= 3sin(kx - c)
and we have from the graph;
f(O)=3
So
Sin(-c) =-1
Therefore C=. Pi/ 2 +2pi n
We have period of the function is pi
2pi/ k
k=2
So it will equal Pi
