Given the table:
x f(x)
2 6
7 3
9 5
To determine the coordinate given in the table, we have the following:
f(2) = 6
f(7) = 3
f(9) = 5
From the answer choices, the only coordinate given is:
f(5) = 9
ANSWER:
f(9) = 5
Answer:
Average speed = 4 mph
Step-by-step explanation:
Given as
Total distance to travel = 6 mile
now, for first 2 mile the avg speed = 6 mph
for next 2 mile the avg speed = 4 mph
and for rest 2 mile the avg speed = 3 mph
so, the average speed of the Richard = 
Total Avg speed = 
Or, = 
×12
= 4
So the total Average speed = 4 mph (Answer)
Answer:
- C. The IQR is the best measure of variability because the distribution has an outlier.
Step-by-step explanation:
We see 75% of data lies in the interval 0 - 48, and the 120 is the outlier.
We wouldn't use the range as it won't be a representation of variability.
<u>The best measure would be IQR:</u>
- <em>The interquartile range is the best measure of variability for such a distribution. </em>
- <em>Because it's based on values that come from the middle half of the distribution, and not influenced by outliers</em>
Correct choice is C.
