Using the mean concept, it is found that on average, it takes him 11.9 seconds to run a 100 yard dash.
<h3>What is the mean?</h3>
The mean of a data-set is given by the <u>sum of all observations in the data-set divided by the number of observations</u>.
In this problem, the three observations are given by:
12.7 s, 11.2 s, 11.8 s.
Hence the mean is:
M = (12.7 + 11.2 + 11.8)/3 = 11.9.
On average, it takes him 11.9 seconds to run a 100 yard dash.

Answer:
30 gram doses
Step-by-step explanation:
First, turn the fractions into decimals.
1/4 gram to .25 gram
7 1/2 gram to 7.5 gram
Then, divide 7.5 total grams by the .25 grams for each dose.
7.5/.25 = 30
Therefore, you can obtain 30 1/4 gram doses from a 7 1/2 gram vial of medication.
