Answer:
A sample size of 35 is needed.
Step-by-step explanation:
We have that to find our 
level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of 
.
So it is z with a pvalue of 
, so 
Now, find the width W as such
In which 
is the standard deviation of the population and n is the size of the sample.
How large must the sample size be if the width of the 95% interval for mu is to be 1.0:
We need to find n for which W = 1.
We have that 
, then 
. So
Rounding up
A sample size of 35 is needed.
Answer:
n > 4
Step-by-step explanation:
Add 1 to both sides
n > 4
3 hundreds is 300, 17 tens is 170, and 2 ones is 2. You add them all and then you get 472.
Considering the asymptotes of the function, the equation that represents the graph is:
<h3>What are the asymptotes of a function f(x)?</h3>
- The vertical asymptotes are the values of x which are outside the domain, which in a fraction are the zeroes of the denominator.
- The horizontal asymptote is the value of f(x) as x goes to infinity, as long as this value is different of infinity.
This function, from the graph, has a vertical asymptote at x = -2, hence the denominator is given by:
x + 2, as x + 2 = 0 -> x = -2.
The horizontal asymptote is of y = 3, hence:
Which means that the function is described by the following rule:

90 x 135% = 90 x 1.35 = 121.5 (notice that instead of finding 35% and adding it on, I included the 90 by mutliplying by 1.xx) - in this case xx - 35 since it was a 35% increase.
