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:
i need to guess that it be inverse and probably a.
Step-by-step explanation:
<u>Answer:</u>
<u>20,000 packages.</u>
<u>Step-by-step explanation:</u>
The rest of the question is as following:
If x represents the number of packages of dog treats, how many packages do they have to sell to break even? Round your answer to the nearest whole number, and do not include units.
=========================================
The function of fixed and variable costs ⇒ C(x) = 1.4x + 2000
The function of revenue ⇒ R(x) = 1.5x
The even situation will happen when costs = revenue
∴ C(x) = R(x)
∴ 1.4 x + 2000 = 1.5x
Solve for x:
∴ 1.5x - 1.4x = 2000
∴ 0.1 x = 2000
∴ x = 2000/0.1 = 20,000
The even will happen when they sell <u>20,000</u> packages
So, To break even, they have to sell more than 20,000 packages .
