average=1.25

what was the low temperature on december 17?

This problem is about statistics. From December 17 to December 24, there are a total of 8 temperatures as data. However, one is missing, so you only have 7. Since the average is known, we start from there:

By adding all the known data, the total is 37. Taking into account the unknown, the sum is (37 + x). Thus,

(37 + x)/8 = 1.25

This results to x = -27. The low temperature on December 17 was -27.

x = -27 is the answer

Step-by-step explanation:

Option B is correct, i.e. 5.00%

Step-by-step explanation:

Given that Jessica’s bank is offering her a loan with a stated rate of 4.90% interest and the interest is compounded every two months.

It means compounding periods, n = 6.

Suppose Principal loan amount = P = $100.

Future value, FV = P(1 + r/n)^(nt)

FV = 100*(1 + 4.9/600)^6 = 105.0011377 ≈ $105.

For a $100 loan, She pay interest = $5.

Hence, the effective interest rate = 5%.
