Answer:
Mean=9.75
Median = 9.5
Mode = 8,9,10,12
Range = 6
Step-by-step explanation:
Arrange number in ascending order;
6,7,8,8,9,9,10,10,11,12,12,15
Mean = sum of terms/number of terms
=(6+7+8+8+9+9+10+10+11+12+12+15)/12
=117/12
=9.75
Median = middle number in a list; since we have two numbers we add them together and divide by 2
= (9+10)/2
= 19/2
=9.5
Mode = 8,9,10,12 (multimodal) this is when there are more than one mode
Range = highest number - lowest number
=15-9
=6
There are 360° around our hexagon.
Every 60° turn will turn one vertex to the next. (1/6 of the way around)
240° turns our point 4 times.
A' would go to C and B' would go to D. (note the counter-clockwise)
Draw yourself a diagram if it helps.
*note: You have to assume that the points are named clockwise around the hexagon

Answer:

Step-by-step explanation:
Let
x ----> the average depth of the resulting layers of ash and rock
we know that
To find out the average depth, divide the cubic kilometers of molten rock by the area where all the ejected material fell.

Convert to meters
Remember that
