Answer:
Step-by-step explanation:
What we're given:
The vector is then
There is a 50/50 chance she does or doesnt take a red marble out the back so its most likely 40 times because of how there are other 2 colors and she is putting back the marbles in the bag
The range is a statistical property that consists of the difference between the biggest and the smallest given number.
In our case, the biggest is 17.3 million and the smallest is 3.3 million:
17.3 - 3.3 = 14.0
The range is 14.0 million acres (option D, 4th option).

Happy homework/ study/ exam!
We know that the basic equation of exponential equation equation is;
y=ab^x
Where a is the y-intercept/starting point and b is the value that x exponentially grows or decays.
From the given equation, the two graphs with other intercepts (not 4) can be removed.
Since b is between 0 and one, this function should be decaying.
Next calculate the value of x when y=1.
1=4(0.5)^x
1/4=(1/2)^x
log₀₋₅(1/4)=x
2=x
Check which of the graphs have y=1, x=2. This would be the second graph, which would represent the equation y=4(0.5)^x
Hope I helped :)
