Assuming compount interest format
for compounded per 1 year
A=future amount
P=present amount
r=rate in decimal
t=time in years
given
P=270
r=5%=0.05
the equaton is
or
for any year, 2009, is year 0, so if you wanted to input the year then
would be for t=what year it was
A.
b. 2009 to 2020
2020-2009=11 years
t=11
f(11)=461.792
about 462 cranes
A.
B. about 462
Answer: C 2x(x - 2) - x = 0
and <u>B</u> 2x² – 5x=0
Step-by-step explanation:
You get 2x(x - 2) - x = 0 by subtracting x from both sides of the original equation.
Then take 2x(x - 2) - x = 0 and distribute to get 2x² - 4x -x = 0
combine the x terma and you end up with 2x² – 5x=0
Answer:
The probability that between 79% and 81%of the 500 sampled wildlife watchers actively observed mammals in 2011 is P=0.412.
Step-by-step explanation:
We know the population proportion π=0.8, according to the 2011 National Survey of Fishing, Hunting, and Wildlife-Associated Recreation.
If we take a sample from this population, and assuming the proportion is correct, it is expected that the sample's proportion to be equal to the population's proportion.
The standard deviation of the sample is equal to:
With the mean and the standard deviaion of the sample, we can calculate the z-value for 0.79 and 0.81:
Then, the probability that between 79% and 81%of the 500 sampled wildlife watchers actively observed mammals in 2011 is:
