Suppose f(x) = ab^x is an exponential GROWTH function. Which function, then, represents exponential DECAY?
Answers
Answer:
,
and
, where
.
Step-by-step explanation:
An exponential growth function that represents exponential decay has ,
and
, where
.
It is the same function. In the case of growth, b represents a number greater than zero, but in decay, it represents a number between 0 and 1.

(p + 5) * 7 = 7 * p + 7 * 5 = 7 * p + 35
The correct result would be 7 * p + 35.
This can also be expressed as 35 + 7p or 7p + 35.

Answer: she is incorrect
Step-by-step explanation:
If Emily had a coupon for 20 percent off her purchase, this means that whatever she bought, the total amount would be reduced by 20%. She will be paying 80%
She finds a backpack she likes on the discount rack. It's original price is $60, but everything on the rack comes with a 30 percent discount.
This means that ordinarily,the amount she is meant to pay on the total goods she is buying is 30% lesser than $60. She will be paying
60 - (30/100 ×60)
60 - 0.3×60 = 60-18 = $42
Since she has a 20% coupon on total cost of goods bought, she would be paying
42 - (20/100 ×42)
42 - 0.2×42
= 42 - 8.4 = $33.6
Therefore,
If Emily says, "thirty percent and twenty percent make fifty percent so that her cost will be $30. She is incorrect. Her cost is $33.6

Answer:
The sample should be as large as 480
Step-by-step explanation:
Probability of having a flu, p = 43/334
p = 0.129
Margin Error, E = 0.03
Confidence Interval, CI= 95%
At a CI of 95%,
The sample size can be given by the relation:
Final answer:
To determine the sample size needed to estimate the population proportion with a desired margin of error, we can use the formula n = (z^2 * p * (1-p)) / (E^2), where n is the required sample size, z is the z-score corresponding to the desired level of confidence, p is the estimated proportion of the population with the characteristic, and E is the desired margin of error. Plugging in the given values, the epidemiologist should take a sample size of approximately 3245 in order to achieve her desired margin of error.
Explanation:
To determine the sample size needed to estimate the population proportion with a desired margin of error, we can use the formula:
n = (z^2 * p * (1-p)) / (E^2)
Where:
- n is the required sample size
- z is the z-score corresponding to the desired level of confidence (in this case, 95% confidence)
- p is the estimated proportion of the population with the characteristic (in this case, the proportion of people with the flu in East Vancouver)
- E is the desired margin of error (in this case, 0.03)
Plugging in the given values:
n = (z^2 * p * (1-p)) / (E^2) = (1.96^2 * 0.129 * 0.871) / (0.03^2) ≈ 3244.42
So, the epidemiologist should take a sample size of approximately 3245 in order to achieve her desired margin of error.
