Slope = change in y / change in x
Use the two pints shown on the graph.
Slope = ( 0- -2) / ( -6 -2)
Slope = 2/-8
Slope = -1/4
answer: slope = -1/4
Answer:
y < (x - 4)(x + 2)
so the critical points are -2 and 4
(-2,-1) will be in the solution
( 0,-2) will not
(4,0) will not.
the answer is ((-2,-1)
Answer:
The equation of the line segment between points A and X is
![sA + (1-s)X, s\in[0,1]](https://tex.z-dn.net/?f=sA%20%2B%20%281-s%29X%2C%20s%5Cin%5B0%2C1%5D)
Then we need that the point C satisfy:
.
This implies that

We replace the value of s in the equation we get from the second component

Then the point
lies on the line through A and X.
Answer:


And the best option would be:
4. Minimum: 869.69; maximum: 961.17
Step-by-step explanation:
We can assume that the variable of interst X is distributed with a binomial distribution and we can use the normal approximation.
For this case the mean would be given by:

And the standard deviation would be:

And if we find the limits we got:


And the best option would be:
4. Minimum: 869.69; maximum: 961.17
