Step-by-step explanation:

$200\:\dfrac{\text{ft}}{\text{sec}}×\dfrac{1\:\text{mi}}{5280\:\text{ft}}×\dfrac{3600\:\text{sec}}{1\:\text{hr}}$

$= 136.36\:\text{mi/hr}$

Note that the units of ft and sec get cancelled out and replaced with miles and hr.

Need to figure out and show work for elapsed time for 9:25pm - 6:15am

ioda

To calculate elapsed time:

Count on in minutes from the earlier time to the nearest hour.

Count on in hours to the hour nearest to the later time.

Count in minutes to reach the later time.

The gap from 9:25 PM to 10 PM is 35 min. The gap from 6 AM to 6:15 AM is 15 min. So far, that accounts for 35+15 = 50 min. The gap from 10 PM to midnight is 2 hours (10+2 = 12). Then the gap from midnight to 6 AM is 6 hours. So we have 2+6 = 8 hours. Add on the minute portion we computed to get 8 hours, 50 minutes.

Answer: 8 hours, 50 minutes

Five students visiting the student health center for a free dental examination during National Dental Hygiene Month were asked h

Andrews [41]

Answer:

[0.9 months, 32.69 months]

Step-by-step explanation:

The mean is

$\bf \bar x=\frac{5+17+12+21+29}{5}=16.8$

The standard deviation is

$\bf s=\sqrt{\frac{(5-16.8)^2+(17-16.8)^2+(12-16.8)^2+(21-16.8)^2+(29-16.8)^2}{5}}=8.1092$

Now, we have to find two values a and b such that the area under the Normal curve with mean 16.8 and standard deviation 8.1092 between a and b equals <em>95% = 0.95 </em>

Using a spreadsheet we find these values are

a = 0.906

b = 32.694

<h3>(See picture) </h3>

and our 95% confidence interval for the mean number of months elapsed since the last visit to a dentist for the population of students participating in the program rounded to two decimal places is

[0.9 months, 32.69 months]
