23. According to one of Tolkien's essays, there were 144 elves originally created by the gods in Middle-Earth. If their numbers tripled every century after that, how many elves were there 1000 years after the creation of Middle-Earth?
A) 432,000 elves
B) 59,049,000 elves
C) 432 elves
D) 8,503,056 elves
Answers
Answer:
D
Step-by-step explanation:
elves in 1000 years = elves now x (rate of increase)^time
elves increase every century. there are ten years in a century. thus time = 1000/100 = 10 years
144 x (3)^10 = 8,503,056 elves

A virus jumps from monkeys to humans. The number of people P(t) who have been infected with the virus t weeks after the jump grows logistically. Suppose that initially 10 people are infected with the virus and that the continuous growth rate is 1.78. It is estimated that in the long run approximately 5000 people will have been infected with the virus. The virus is spreading the fastest approximately:________
a. 3.5 weeks after the jump.
b. 4.0 weeks after the jump.
c. 4.5 weeks after the jump.
d. 5.0 weeks after the jump.
e. None of the above is correct.
Answers
Answer:
e. None of the above is correct.
Step-by-step explanation:
The general formula for exponential growth is;
P= a(1 + r)^t
Where;
P = total number infected after a given time interval
a = initial number of infected people
r = growth rate of infection
x= time taken in weeks
Hence;
5000= 10(1 + 1.78)^t
5000/10 = (1 + 1.78)^t
500 = (1 + 1.78)^t
log 500 = tlog(1 + 1.78)
t = log 500/log(1 + 1.78)
t = 2.699/0.444
t = 6 weeks
The virus is spreading the fastest approximately 5.0 weeks after the jump.
What is exponential?An exponential equation is an algebraic expression that has an equality and at least one unknown in one of its exponents. To be considered an equation, an expression must have at least one unknown, which is an unknown number represented by a letter, and an equality relationship.
The general formula for exponential growth is;
P= a(1 + r)^t
Where;
P = total number infected after a given time interval = 5000a = initial number of infected people = 10r = growth rate of infection = 1.78x= time taken in weeksHence;
[tex]5000= 10(1 + 1.78)^t\\5000/10 = (1 + 1.78)^t\\500 = (1 + 1.78)^t\\log 500 = tlog(1 + 1.78)\\t = log 500/log(1 + 1.78)\\t = 2.699/0.444\\t = 6 weeks[/tex]
[tex]t=6-1=5 weeks[/tex]

A chemist examines 25 geological samples for bromide concentration. The mean bromide concentration for the sample data is 0.502 cc/cubic meter with a standard deviation of 0.0313. Determine the 98% confidence interval for the population mean bromide concentration. Assume the population is approximately normal. Step 1 of 2 : Find the critical value that should be used in constructing the confidence interval. Round your answer to three decimal places.
Answers
Answer:
The critical value that should be used is T = 2.492.
The 98% confidence interval for the population mean bromide concentration is between 0.486 cc/m³ and 0.518 cc/m³
Step-by-step explanation:
We have the standard deviation for the mean, which means that the t-distribution is used to solve this question.
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 25 - 1 = 24
98% confidence interval
Now, we have to find a value of T, which is found looking at the t table, with 24 degrees of freedom(y-axis) and a confidence level of [tex]1 - \frac{1 - 0.98}{2} = 0.99[/tex]. So we have T = 2.492, which is the critical value that should be used.
The margin of error is:
[tex]M = T\frac{s}{\sqrt{n}} = 2.492\frac{0.0313}{\sqrt{25}} = 0.016[/tex]
In which s is the standard deviation of the sample and n is the size of the sample.
The lower end of the interval is the sample mean subtracted by M. So it is 0.502 - 0.016 = 0.486 cc/m³
The upper end of the interval is the sample mean added to M. So it is 0.502 + 0.016 = 0.518 cc/m³
The 98% confidence interval for the population mean bromide concentration is between 0.486 cc/m³ and 0.518 cc/m³
