Answer:
- 2% growth per year
- 25,000 to start
- 12 years
- 31,706 currently
Step-by-step explanation:
The base of the exponent is (1 +0.02). The value 0.02 = 2% is the growth rate. It is positive, signifying a 2% rate of growth per year. (Negative values would mean decay.)
The number 25000 that multiplies the exponential term is the value of the expression when the exponent is zero. It represents the starting population.
The exponent is said to be in years, so the time is 12 years.
The current population is the value of the expression:
25,000(1.02^12) ≈ 31,706 . . . . current population

Answer with explanation:</h2>
Let p be the proportion of of all adults in the town that have been exposed to this strain of the flue .
As per given , we have
∵ is two-tailed , so the test is a two-tailed test.
Test statistic :
, where p= population proportion
= sample proportion
n= sample size
Put n= 6 and and p=0.08
P-value for two-tailed test : 2P(Z>|z|)
=2P(Z>|-0.415|)
=2P(Z>0.415)
=2[1-P(Z≤0.415)] [∵ P(Z>z)=1-P(Z≤z)]
=2(1-0.6609) [ by z-table]
=0.6782
Decision : Since the p-value(0.6782) is > significance level(0.01) , so we fail to reject the null hypothesis.
We conclude that that we do not have sufficient evidence to support the claim that the proportion of all adults in the town that have been exposed to this strain of the flue differs from the nationwide percentage of 8%.
Answer:
C.
Step-by-step explanation:
15 x 16=240 x 2= 480
57 x 20= 1140
1140 + 480 = 1620
Answer:
1. Solution = (4,3) and they intersect.
2. Solution = Infinite, this means that the lines overlap each other constantly.
3. Equations = x + y=73 and 2.35x + 1.34y = 141.25
