Question

If it has been reported that the first week in May NC has an average daily temperature of 88 degrees. The first week had recorded temperatures of 90, 83, and 85. What is the probable average temperature of the remainder of the week?

Answer 1

To find the probable average temperature for the remaining days of the week, sum the known temperatures, calculate the total expected temperature for the week, subtract the known sum from the total, and divide the remainder by the number of days left. The probable average temperature for the remaining days is 89.5 degrees.

Step-by-step explanation:

Given the information that the first week in May in North Carolina (NC) has an average daily temperature of 88 degrees, and the recorded temperatures so far are 90, 83, and 85 degrees, you can calculate the probable average temperature for the remainder of the week using these steps:

1. Sum the known temperatures: 90 + 83 + 85 = 258 degrees.
2. Since the average for the week is known to be 88 degrees, multiply this by 7 days to get the total temperature for the week: 88 x 7 = 616 degrees.
3. Subtract the sum of known temperatures from the total week temperature: 616 - 258 = 358 degrees.
4. Divide this remainder by the number of days left in the week (7 days in a week minus the 3 days of known temperatures): 358 / (7-3) = 358 / 4 = 89.5 degrees, which is the probable average temperature for the remaining 4 days.
