The number of wolves in a wildlife preserve is estimated to have increased continually by 3% per year. If the population is now estimated at 5,400 wolves, how many were present 10 years ago?
Answers
Since this is an exponential function, it'll be: f(t)=54,000*1.03^t
But we want to know how many wolves there were 10 years ago.
For that, we simply "turn time around", as in: f(t)=54,00*1.03^-t
This displays a decreasing number of wolves, as you turn back time.
Now we simply calculate 54,000*1.03^-10
which is approximately 40,200?

Final answer:
Tyrese has used 7 out of his 35 initial tickets. This translates to a 20% decrease in the number of tickets he has.
Explanation:
Tyrese started with 35 tickets and now has 28 tickets. To find the percent of decrease in the number of tickets, first, we need to find how many tickets he has used. He has used 35 - 28 = 7 tickets.
Next, we find the percentage decrease using the formula:
Percent Decrease = (Decrease/Original amount) x 100%
So in this case, the decrease is 7 tickets, and the original amount is 35 tickets.
Percent Decrease = (7/35) x 100% = 20%.
Therefore, the percent of decrease in the number of tickets that Tyrese has is 20%.

The calculated value of the area of the parallelogram is 99 square cm
Calculating the area of the parallelogram
From the question, we have the following parameters that can be used in our computation:
The parallelogram
Where we have
Height = 11 cm
Base = 5 cm + 4 cm = 9 cm
The area of the parallelogram is calculated as
Area = Base * Height
Substitute the known values in the above equation, so, we have the following representation
Area = 11 * 9
Evaluate the product of 11 and 9
So, we have the following representation
Area = 99
Hence, the area of the parallelogram is 99 square cm

Answer:
To figure out the variance, divide the sum, 82.5, by N-1, which is the sample size (in this case 10) minus 1. The result is a variance of 82.5/9 = 9.17. Standard deviation is the square root of the variance so that the standard deviation would be about 3.03.
