Answer:
a) The initial quantity is 2.9.
b) The initial quantity is 2.9.
c) The multiplier is 1.05 > 1, and thus, the quantity is growing.
Step-by-step explanation:
Exponential equations:
Have the following format:
In which A(0) is the initial amount and k is the multiplier.
If k > 0, the quantity is growing.
If k < 0, the quintity is decaying.
In this question:
a, b. The initial quantity is
P(0). So
The initial quantity is 2.9.
c. Is the quantity growing or decaying?
The multiplier is 1.05 > 1, and thus, the quantity is growing.
Answer:
416025 grade-point averages must be obtained so that the sample mean is within 0.006 of the population mean. But this size too big and is not practical.
Step-by-step explanation:
Minimum required grade-point averages can be found using the formula
N≥ where
- N is the sample size
- z is the corresponding z-score in 99% confidence level (2.58)
- s is the standard deviation (1.5)
- ME is the margin of error (0.006)
Putting these numbers in the formula we get
N≥ =416025
