The graphs that are density curves for a continuous random variable are: Graph A, C, D and E.
<h3>How to determine the density curves?</h3>
In Geometry, the area of the density curves for a continuous random variable must always be equal to one (1). Thus, we would test this rule in each of the curves:
Area A = (1 × 5 + 1 × 3 + 1 × 2) × 0.1
Area A = 10 × 0.1
Area A = 1 sq. units (True).
For curve B, we have:
Area B = (3 × 3) × 0.1
Area B = 9 × 0.1
Area B = 0.9 sq. units (False).
For curve C, we have:
Area C = (3 × 4 - 2 × 1) × 0.1
Area C = 10 × 0.1
Area C = 1 sq. units (False).
For curve D, we have:
Area D = (1 × 4 + 1 × 3 + 1 × 2 + 1 × 1) × 0.1
Area D = 10 × 0.1
Area D = 1 sq. units (True).
For curve E, we have:
Area E = (1/2 × 4 × 5) × 0.1
Area E = 10 × 0.1
Area E = 1 sq. units (True).

Answer:
30%
Step-by-step explanation:
The answer is off by 30%, as the scale is off by 3 pounds. 3/10=30
Answer:
10 1/12
Step-by-step explanation:
In order to subtract fractions, you have to give them a common denominator.
18 1/2 can be rewritten as 18 6/12, as they are the same thing and 6/12 simplifies to 1/2. We make it 6/12 because we have to subtract it by 8 5/12, and the denominators are both 12.
So now we have 18 6/12 - 8 5/12, which gives us 10 1/12.

Answer:
1017.9 ft^3
Step-by-step explanation:
We know the inside dimension at floor level will be 18 feet across, so that may not be the answer that is being asked for. We also know it will be 12 ft high inside, so that may not be the answer, either. We're not quite sure what "how big" is supposed to mean.

Perhaps the question is trying to ask for the volume of the teepee. That will be given by the formula ...
V = (1/3)πr^2·h
V = (1/3)π(9 ft)^2·(12 ft) = 324π ft^3
V ≈ 1017.9 ft^3
The interior volume will be about 1017.9 cubic feet.
