1/4 divided by 2. Hopefully this helped!!
Answer:
Hence, the average rate of change is:
Step-by-step explanation:
We are asked to calculate the average value of the function:
in 2 ≤ x ≤ 6
The average rate of change of the function f(x) in the interval 2 ≤ x ≤ 6 is given as:
Now,
Hence, the average rate of change is:
Hence, the average rate of change is:
Answer:
It´s obtuse
Let me know if it´s wrong
Answer:
The number of surveys needed to be collected is 152.
Step-by-step explanation:
The (1 - <em>α</em>)% confidence interval for population proportion <em>p</em> is:
The margin of error for this interval is:
The information provided is:
Compute the critical value of <em>z</em> for 89.9% confidence level as follows:
*Use a <em>z</em>-table.
Compute the sample size value as follows:
Thus, the number of surveys needed to be collected is 152.
