Answer:
A possible measure of Line segment TS is 4.0 ft
Step-by-step explanation:
<u><em>The options of the question are</em></u>
1.6 ft 3.0 ft 3.2 ft 4.0 ft
we know that
In any triangle:
The shortest side is always opposite the smallest interior angle.
The longest side is always opposite the largest interior angle
In this problem
That means
Rewrite the expression
so
therefore
A possible measure of Line segment TS is 4.0 ft
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.
