Given that the table shows the total miles Uyen has run this week.
The image of the table is attached below.
The total distance from the table is 
The total distance this week is 1.5 times the distance that she ran last week.
We need to determine the number of miles that Uyen run last week.
<u>The number of miles Uyen run last week:</u>
Let x denote the number of miles that Uyen run last week.
Let us write the equation from the given data.
Thus, we have;
Dividing both sides by 1.5, we have;
Hence, the value of x is 14.8 miles.
Thus, Uyen ran 14.8 miles last week.
You didnt show the rest of the picture i can't help if i can't see.
Using the coefficient of variation, it is found that students were more variable in their marijuana consumption.
<h3>What is the coefficient of variation of a data-set?</h3>
The coefficient of variation of a data-set is given by the <u>division of the standard deviation of the data-set by the mean of the data-set</u>. The higher the coefficient, the more variable the data-set is.
In this problem, for marijuana consumption, the average was 3.74 and the standard deviation was 1.47, hence:
For depression levels, the average was 19.32 and the standard deviation was 3.18, hence:
Due to the higher coefficient, students were more variable in their marijuana consumption.

Answer:
Henry's baseball practice starts at 2:00, will last an hour and forty-five minutes, and will end at 3:45.
Step-by-step explanation:
2 + 1 = 3
3 + 45 minutes = 3 : 45
3.75 miles or 3 3/4 would be your answer
