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%

stew reads at the fastest rate of 265 words per minute.

step-by-step explanation:

it's a given that felicia reads at 260 word per minute and on connie's graph we can see that she reads 200 words per minute. since stew's table tells us that he read 795 in 3 minutes, we can divide 795 by 3 to find out how many words he reads per minute.

795/3 = 265

stew reads 265 words per minute - he reads at the fastest rate since felecia reads at 260 words per minute and connie reads at 200 words per minute.

stew (265) > felecia (260) > connie (200)
