To figure out two separate dimensions for finding a Volume of 100 cubic cm, you will look at the factors of 100 that will result in an answer of 100.
You will need the area of the triangular base and the height of the pyramid.
I will use 3 as the height for both triangle because in the formula, you will multiply by 1/3. This means you will need to get an area of 100 for each triangle.
Because you will divide by 2, you need to find 2 different sets of factors that will give you 200. I chose 20 and 5 and 25 and 4.
Please see the attached work for the calculations.
Triangle #1: Triangle #2:
b = 40 cm b = 50 cm
h(of the base triangle) = 5 cm h(of the base triangle) = 4 cm
H(of the pyramid) = 3 cm H(of the pyramid) = 3 cm

<h3>Answer: Choice A</h3><h3>y = (-2/3)x + 12</h3>
================================================
Work Shown:
We will only focus on the two points that are on the regression line.
Those two points are (3,10) and (12,4)
Let (x1,y1) = (3,10) and (x2,y2) = (12,4)
Find the slope of the line through (x1,y1) = (3,10) and (x2,y2) = (12,4)
m = (y2 - y1)/(x2 - x1)
m = (4 - 10)/(12 - 3)
m = -6/9
m = -2/3
Plug m = -2/3 and (x1,y1) = (3,10) into the point slope formula
Solve for y.
y - y1 = m(x - x1)
y - 10 = (-2/3)(x - 3)
y - 10 = (-2/3)x + (-2/3)(-3) ... distribute
y - 10 = (-2/3)x + 2
y - 10 + 10 = (-2/3)x + 2 + 10 .... add 10 to both sides
y = (-2/3)x + 12
This matches up with what the graph shows because the regression line intersects 12 on the y axis, so the y intercept is 12.
y = (-2/3)x + 12 is in the form y = mx+b with m = -2/3 as the slope and b = 12 as the y intercept.
Answer:
D
Step-by-step explanation:
You basically just add the numbers where x is. I tried it with 5 and both equalled 28. Using 5 as x makes the equation equal which is what we are looking for. So the answer is x=5.
