Answer:
110,323.7505 or 110,324
Step-by-step explanation:
We need to take the integral of b(t) - d(t) over the interval of [0, 10]. This will tell us the average population over a 10 year period.
We are counting all the birth (additions to the population) and counting the deaths (subtractions to the population), so overall population is calculated by:
Population = birth rate - death rate
We take the anti derivatives of b(t) and d(t), see all work on the attached photo
1.34 inches is 3.35%
2.54 inches is 6.35%.
Take the numbers and divide by 40!
247 / 13 = 323 / x....247 to 13 hrs = 323 to x hrs
cross multiply
(247)(x) = (323)(13)
247x = 4199
x = 4199 / 247
x = 17 hrs <===
Taking the cubic root of a number is the same as raising that number to the power of 1/3.
Moreover, we have
So, we have
The median is 50.
The first quartile is 20, the third is 65, the difference is 45.
