Answer:
$321562.50
Step-by-step explanation:
Exponential growth can be modeled by the formula , with y representing the final value, a being the starting value, r being the growth rate, and x being the number of time intervals passed.
To figure out the rate, we must use the values given from the months we have data of. Our starting value is 60,000 , ending value is 105,000 , and given that monthly sales are given, we can assume that sales grew exponentially each month. There were 4 years, or 48 months, that the store had to grow. Our formula is thus
To solve for r, we can first divide both sides by 60,000 , then put each side to the power of 1/48, resulting in
Since we know our rate, and there are 8 years/96 months between January 2005 and January 2013, we can make our starting value 105,000 , plug (1.75)^(1/48) for r and 96 for x in , and go from there.
Our final value is then
. We were able to turn 1.75^(1/48)^(96) into 1.75² using the exponent rule stating that x^y^z = x^(y*z)
Answer:
Only the question 2 is a statistical question.
Step-by-step explanation:
<u>Questions</u>
2. How much time do the students in my school spend on the Internet each night?
3. What is the height of the tallest waterslide at Wild Rides Water Park?
4. What are the cabin rental prices for each of the state parks in Kentucky?
The question 2 is a statistical question.
Is the only question that can be answered with a parameter of a population (mean number of hours spent on the internet by the students).
The other two ask for individual values: the height of the tallest waterslide at Wild Rides Water Park, and the cabin rental prices for each of the state parks in Kentucky. This need specific values that are not statistical, but deterministic.
Answer:
Step-by-step explanation:
So first, we know that:
And:
This means that instead of 1, if we put two in like so:
Then we can substitute the f(2):
Therefore, g(2)=1.
Geoff charges $1.25 more than Anne (27/3=9)-(31/4=7.75)
Take to total number of people attending and subtract the number of adults. The remainder are the children
2,451 - 745 = 1,706
