Answer:
A
Step-by-step explanation:
Prism A Volume
The Column of Prism A = Base (Area) * Height.
I think you have to assume that the triangle is a right triangle.
Area of the triangle = 1/2 * 9 * 7
Area of the triangle = 1/2 63
Area of the triangle = 31.5
Volume of the Prism = area of the triangle * thickness
Volume of the prism = 31.5 * 4
Volume of the prism = 126 m^3
Prism B = L * w * h
Prism B = 8 * 8 * 2
Prism B = 128
Prism A has the least volume by just a little.
Answer:
-4
Step-by-step explanation:
18x - 9(x - 1) = 5(3x + 3)
Step 1: Distribute
18x - 9x - 9 = 15x + 15
Step 2: Combine like terms
9x - 9 = 15x + 15
Step 3: Solve by using opposites terms, try to get x on one side and the solution on the opposite side
9x - 9 = 15x + 15
-9x -9x
-9 = 6x + 15
-15 -15
-24 = 6x
/6 /6
-4 = x
Given that n = 18, then the degree of freedom is n - 1 = 17.
From the table of Chi Square
The value of
to the left for 95% confidence interval given a degree of freedom of 17 is 8.672
Answer:
Step-by-step explanation:
1 1/8 = 9/8
9 - 7 = 2
9/8 - 7/8 = 2/8
2/8 = 1/4
