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).

if you add them all its 340 and the square number is 9
Step-by-step explanation:
Below is an attachment containing the solution.
Answer:
B
Step-by-step explanation:
Answer:
The correct option is A) The growth factor of the investment.
Step-by-step explanation:
Consider the provided exponential function.
Where V(t) is the total value after t years.
Here the function is in the form of Exponential Growth:
Where b value is the growth factor.
By comparing we get that the constant '1.125' represents the growth factor by which our value is increasing each year.
Constant '30,000' represents the initial value i.e. the investment made.
Hence, the correct option is A) The growth factor of the investment.
