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.
The option fourth "There is a strong negative relationship between x and y" is correct.
<h3>What is correlation?</h3>It is defined as the relation between two variables which is a quantitative type and gives an idea about the direction of these two variables.
The options are:
- There is no relationship between x and y.
- There is a weak negative relationship between x and y.
- There is a strong positive relationship between x and y.
- There is a strong negative relationship between x and y.
We have data:
x 7 8 9 10 11 12 13
y 13 10 7 6 5 3 0
The value of correlation r = -0.9847
As we know the value of r between -1 to +1
If r = 1 (perfect and positive correlation)
if r = -1 (perfect and negative correlation)
We have r = -0.9847
The value is near to -1 which means there is a strong negative relationship between x and y.
Thus, the option fourth "There is a strong negative relationship between x and y" is correct.
