Answer:
There is a gap in Plot A, but not in Plot B
Step-by-step explanation:
There is a gap in Plot A because there are 2 dots above 7 hours, 0 dots above 8 and 9 hours and 1 dot above 10 hours.
There is no gap in Plot B.
The data is spread widely across Plot A, but not across Plot B.
(4.8 x 10^6)(3.6 x 10^3) / (2 x 10^5)
= (4.8 x 3.6) x 10^(6+3) / 2 x 10^5
= 17.28 x 10^9 / 2 x 10^5
= (17.28 / 2) x 10^(9 - 5)
= 8. 64 x 10^4
