Step-by-step explanation:
to find mean
add all numbers, then divide by how many set they given
to find median
you need to arrange them ascending order
then what is the number in the middle
to find mode
find what most repeated number
Answer:
<em>The rock is 52.2 feet high</em>
Step-by-step explanation:
<u>Similar Triangles
</u>
The triangle formed by the rock, mirror and the ground is similar to the triangle formed by Carlos, the mirror and the ground (see image below). This means its sides are proportional, and
We want to calculate the height of the rock, thus we solve for H
This could get complicated. Please try to follow my steps carefully:
Begin by writing the equation to be solved: <u>12E - 4 = 0</u>
Add 4 to each side of the equation: 12E = 4
Divide each side by 12: E = 4/12 = 1/3 .
A2/4
Step-by-step explana
If the equation y = 3x + 2 is changed to y = -3x + 2, how will the graph of the line change?
A) It will shift down 3 units.
B) It will shift left

units.
C) It will slope in the opposite direction.
D) The new line will be parallel to the original line.
Answer:
Step-by-step explanation:
All you need to do is isolate the x.
First, add 64 to both sides:
Then, take the square root of both sides:
Actually, that is:
Here's the reason for that. An example would be:
Here, you'd take the square root of both sides to solve for x.
Right? But X could also be a -2, because a negative times a negative is a positive.
Therefore, or
