Mean 6.6
Median 6
Mode 3
Range 10
not positive on the 6.6 but the rest should be good
Answer:
A is the answer
Step-by-step explanation:
m¹⁶/4n¹²
Step-by-step explanation:
multiply the 1 1/2 by 2 to get 3.
find the closest number that is divisible by 3
3*7 is 21.
We now have to multiply 7 by 2 since we did that to our mixed number to get a whole number.
There is still a 1 1/2 left over. Simply add 1 to 14.

Answer: 40</h3>
=================================================
Explanation:
JQ is longer than QN. We can see this visually, but the rule for something like this is the segment from the vertex to the centroid is longer compared to the segment that spans from the centroid to the midpoint.
See the diagram below.
The ratio of these two lengths is 2:1, meaning that JQ is twice as long compared to QN. This is one property of the segments that form when we construct the centroid (recall that the centroid is the intersection of the medians)
We know that JN = 60
Let x = JQ and y = QN
The ratio of x to y is x/y and this is 2/1
x/y = 2/1
1*x = y*2
x = 2y
Now use the segment addition postulate
JQ + QN = JN
x + y = 60
2y + y = 60
3y = 60
y = 60/3
y = 20
QN = 20
JQ = 2*y = 2*QN = 2*20 = 40
--------------
We have
JQ = 40 and QN = 20
We see that JQ is twice as larger as QN and that JQ + QN is equal to 60.
