In this problem WP means what percent
20 = WP X 160
solve for WP, by dividing both sides by 160
and you get:
0.125 = WP
Change your decimal into a percent by multiplying by 100%
12.5% is your result.
Answer:
99.7%
Step-by-step explanation:
Given that mean (μ) = 394.3 ms and standard deviation (σ) = 84.6 ms.
The empirical rule states that for a normal distribution:
- 68% falls within one standard deviation (μ ± σ)
- 95% falls within two standard deviation (μ ± 2σ)
- 99.7% falls within three standard deviation (μ ± 3σ)
one standard deviation = 394.3 ± 84.6 = (309.7, 478.9). 68% falls within 309.7 and 478.9 ms
two standard deviation = 394.3 ± 2 × 84.6 = (225.1, 563.5). 95% falls within 225.1 and 563.5 ms
three standard deviation = 394.3 ± 3 × 84.6 = (140.5, 648.1). 99.7% falls within 140.5 and 648.1 ms
Answer:
more than
Step-by-step explanation: less than because 60 + 90 = 150 and you said 1 hour plus 1 hour and a half so your answer is more than because 150 is more than 100
If you were going to multiply those two numbers, the answer would be D, 192.
