Considering that outliers will be disconsidered, the correct statement is:
The coach can use the Interquartile Range to summarize the runners' times.
<h3>What is the Interquartile Range(IQR) of a data-set?</h3>
It is the values of a data-set that are between the 25th percentile and the 75th percentile, that is, the middle 50% of the values. It's advantage in certain situation is that it disconsiders outliers.
In this problem, the best way to summarize the times is disconsidering outliers, hence the Interquartile Range is used, as it indicates how close all runners' times were to each other.

Answer:
16 is the answer
Step-by-step explanation:
4 4/5 x 10/3
True because tan(20)=2.1 and cot(20)=is o.44
Answer:
d. 2
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
45a−25+7a=79
45a+−25+7a=79
(45a+7a)+(−25)=79(Combine Like Terms)
52a+−25=79
52a−25=79
Step 2: Add 25 to both sides.
52a−25+25=79+25
52a=104
Step 3: Divide both sides by 52.
52a
52
=
104
