A TV show had 3.6 x 104 viewers in the first week and 4.1 x 104 viewers in the second week. Determine the average number of viewers over the two weeks and write the final answer in scientific notation.

3.85 x 104
7.7 x 104
3.85 x 108
7.7 x 108

Answer 1

3.85 x 10^4

Explanation:

I am going to assume that 3.6x104 is 3.6x10^4

mean = ((3.6 x 10^4)+(4.1 x 10^4))/2

mean = (36,000+41,000)/2

mean = 77,000 / 2

mean = 38500

mean = 3.85 x 10^4
