Question

A TV show had 4.4 x 10^6 viewers in the first week and 3.1 x 10^6 viewers in the second week. Determine the average number of viewers over the two weeks and write the final answer in scientific notation.
a) 3.75 x 10^12

b) 3.75 x 10^6

c) 7.5 x 10^12

d) 7.5 x 10^6

Answer 1

To find the average number of viewers over the two weeks, you need to add the total number of viewers for both weeks and then divide by two.

Total number of viewers = 4.4 x 10^6 + 3.1 x 10^6 = 7.5 x 10^6

Average number of viewers = (7.5 x 10^6) / 2 = 3.75 x 10^6

Therefore, the final answer in scientific notation is:

b) 3.75 x 10^6
