Answer:
c) 62.
Step-by-step explanation:
Let x represent number of customers came in on the fifth day.
We have been given that the mean number of customers for those four days is 52. So total number of customers on 4 days would be 4 times 52 that is 208 customers.
We know that mean of a data set is equal to sum of all data points divided by number of data points.
Total number of customers on 5 days would be
and total number of days is 5.
Since we need a mean of 54, so we can set mean of 5 days equal to 54 as:

Multiply both sides by 5:




Therefore, 62 customers must come in on the fifth day to make the five-day mean 54 and option 'c' is the correct choice.

Answer:
By the Pythagorean theorem, the diagonal length (d) of the square is
d² = 7² + 7²
d = √98 ≈ 9.8995
Since the diameter of the circle (11 cm) is greater than the diagonal length of the square (9.9 cm), you know the square will fit into the circle without touching.

Answer:
C. $40,000
Step-by-step explanation:
Basic salary = $500
Expected earning this week = $2,500
Expected commission on appliance sales = $2,500 - $500 = $2,000
