Wait times at an orthodontist’s office are typically 17 minutes, with a standard deviation of 2 minutes. What percentage should be seen by the doctor between 11 and 23 minutes for this to be considered a normal distribution?

0.997

Step-by-step explanation:

The mean wait times at an orthodontist’s office are typically 17 minutes, with a standard deviation of 2 minutes.

We want to find the percentage that should be seen by the doctor between 11 and 23 minutes for this to be considered a normal distribution.

We know that 23= 17+3(2), is 3 standard deviation above the mean.

Also, 11=17-3(2), is 3 standard deviation below the mean.

According to the empirical rule, approximately 99.7% of the distribution are within 3 standard deviations of the mean.

the answer is 45 i just did it on oddesy ware

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.
