Calculate 16% of 850.
The way I do this is by breaking it up into smaller pieces.
First I would find 10% of 850. To do this I need to divide 850 by 10, as 100%/10 gives us 10%, which is what we need.
So 10% = 85
Then we need 5%, which is half of 10%, therefore half of 85,
So 5% = 42.5
Then we need 1% which is 10%/10, so 85/10.
So 1% = 8.5
Then we add all these together to get 16%.
So 16% = 136
They predict that 102 people will come back, which is less than the 16% that should come back to stay again, so their prediction is too low.
Answer:
as x approaches negative infinity, h(x) approaches positive infinity
Step-by-step explanation:

Answer:
The value of a = 3
Step-by-step explanation:
Given the function
From the attached graph, it is clear that
at x = 0,
∵ 
Thus
When x = 0, the y-intercept will be:
From the attached figure, it is clear that
at x = 0, the value of y = 3
so
putting y = 3 in the equation
3 = a ∵ 
Therefore, the value of a = 3
<span>A medical researcher wants to investigate the amount of time it takes for patients' headache pain to be relieved after taking a new prescription painkiller. She plans to use statistical methods to estimate the mean of the population of relief times. She believes that the population is normally distributed with a standard deviation of 18 minutes. How large a sample should she take to estimate the mean time to within 4 minutes with 97% confidence?
