Answer:

<em>I</em>'[−3, −2], <em>Q</em>'[2, 0], <em>?</em>'[0, 1], <em>E</em>'[−3, −1]

Step-by-step explanation:

The line of reflection is at <em>y = −</em><em>2</em>,<em> </em>so looking at the line and where the coordinates of the shape are, you will have this:

<em>I</em>[−3, −2] → <em>I</em>'[−3, −2] (on the line, so it remains the same)

<em>Q</em>[2, −4] → <em>Q</em>'[2, 0]

<em>?</em>[0, −5] →<em> </em><em>?</em>'[0, 1]

<em>E</em>[−3, −3] → <em>E</em>'[−3, −1]

I am joyous to assist you anytime.

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

Regular hexagon ABCDEF rotates 240° counterclockwise about its center to produce hexagon A'B'C'D'E'F'. Which points will A' and
Ipatiy [6.2K]
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:

166\frac{2}{3}\ m

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.

so

\frac{100\ km^3}{600\ km^2}=\frac{1}{6}\ km

Convert to meters

Remember that

1\ km=1,000\ m

so

\frac{1}{6}\ km=\frac{1}{6}(1,000)=\frac{1,000}{6}=\frac{500}{3}\ m

Convert to mixed number

\frac{500}{3}\ m=\frac{498}{3}+\frac{2}{3}=166\frac{2}{3}\ m
