Answer:
A. (0, 6) and (−2, 0)
Step-by-step explanation:
The given equations are:
and
We equate the two equations to find their point of intersection;
We equate everything to zero to get;
When x=0, y=3(0)+6=6
One solution is;
(0,6)
When x=-2,
y=3(-2)+6=0
Another solution is;
(-2,0)

Answer:
We need a sample of at least 82 female white-tailed deer
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 margin of error M as such
In which is the standard deviation of the population and n is the size of the sample.
What sample size would you need to in order to estimate the mean weight of all female white-tailed deer, with a 99% confidence level, to within 6 pounds of the actual weight?
We need a sample of size at least n.
n is found when . So
Rounding up
We need a sample of at least 82 female white-tailed deer
