Answer: It will take of an hour to complete the test.
Step-by-step explanation:
We need to convert the mixed number to an improper fraction:
Now, we need to make the following add the fractions in order to calculate how many hours will it take to complete the test. Then, we get:
Therefore, it will take of an hour to complete the test.
It takes 8.35 hours for the size of the sample to double
Step-by-step explanation:
The form of the continuous exponential growth model is
, where
- A is the new value
- P is the initial value
- r is the rate of growth or decay in decimal
- t is the time
∵ The growth rate is 8.3%
∴ r = 8.3 ÷ 100 = 0.083
∵ The size of the sample will doubled in t hours
∴ A = 2 P
Use the formula of the contentious exponential growth above
∵
- Divide both sides by P
∴
- Insert ㏑ in both sides
∴
- Remember because ㏑(e) = 1
∴
- Divide both sides by 0.083
∴
∴ t = 8.35 hours to the nearest hundredth
It takes 8.35 hours for the size of the sample to double
