What’s 9 divided by 3/2

Mathematics
2 answers:
Anit [1.1K]3 years ago

Answer:

6

Step-by-step explanation:

9 divided by 3/2 is the same thing as 9*2/3. This is because 3/2 and 2/3 are reciprocals. When you are dividing by fractions I like to use the phrase: keep, change, flip. We keep the first number the same, we change the division to multiplication, and then we flip the fraction. Than you just multiply across like normal and that is your answer. Hope this helps :)

A random sample of adult female reaction times has a sample mean of x¯=394.3 milliseconds and sample standard deviation of s=84.
s2008m [1.1K]

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:

  1. 68% falls within one standard deviation (μ ± σ)
  2. 95% falls within two standard deviation (μ ± 2σ)
  3. 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
