Answer:99.7%

Step-by-step explanation:

The empirical rule states that for a normal distribution, almost all of the

data will fall within three standard deviations of the mean. It states that

1) 68% of the data falls within one standard deviation of the mean.

2) 95% of the data falls within two standard deviations of the mean.

3) 99.7% of the data falls within three standard deviations of the mean.

From the information given, the mean is $70 and the standard deviation is $9. We want to determine the percentage of her phone bill that is between 43% and 97%

Looking at ±3 standard deviations of the mean, it becomes

70 ± 3×9 = 70 ± 27

The value is between 70 - 27 = 43 and 70 + 27 = 97

Therefore, the percentage of her phone bills that is between 43% and 97% is 99.7%

Ellie runs 5/6 mile in 10 minutes.what is ellie's speed in miles per minute?
olganol [36]

Answer:

1/12 miles/minute

Step-by-step explanation:

To figure out how fast ellie runs in 1 minute, we can set up this equation:

5/6 = 10x (x being the speed per minute)

We can divide both sides by 10

5/60 = x

Then simplify the fraction to get:

1/12 = x
