Answer:
55.563
Step-by-step explanation:
Given the following :
Mean(m) point = 73
Standard deviation( sd) = 10.6
Lower 5% will not get a passing grade (those below the 5% percentile)
For a normal distribution:
The z-score is given by:
z = (X - mean) / standard deviation
5% of the class = 5/100 = 0.05
From the z - table : 0.05 falls into - 1.645 which is equal to the z - score
Substituting this value into the z-score formula to obtain the score(x) which seperates the lower 5%(0.05) from the rest of the class
z = (x - m) / sd
-1.645 = (x - 73) / 10.6
-1 645 * 10.6 = x - 73
-17.437 = x - 73
-17.437 + 73 = x
55.563 = x
Therefore, the score which seperetes the lower 5% from the rest of the class is 55.563
Just grab your calculator and multiply it by itself or use the 'square' function

Answer:
FICA tax should his employer withhold be $24.92 .
Option (D) is correct .
Step-by-step explanation:
As given
Bill’s FICA tax is 7.65% of his earnings of 325.78 per week.
7.65 % is written in the decimal form.
= 0.0765
FICA tax price = 0.0765 × Earning of a week
Putting values in the above
FICA tax price = 0.0765 × 325.78
= $ 24.92 (Approx)
Therefore the FICA tax should his employer withhold be $24.92 .
Option (D) is correct .
