The coordinates of B would be (2, -4)
In order to find this, we need to know that the value of M's points will always be the average of A and B's points. This is because it is the midpoint. Therefore we can use the following formula.
Value of x
(A + B)/2 = M
(-8 + B)/2 = -3
-8 + B = -6
B = 2
Then we can do the same for the y values
Value of y
(A + B)/2 = M
(-2 + B)/2 = -3
-2 + B = -6
B = 4

Answer:
Step-by-step explanation:
The formula for volume of a cylinder is
V = πr²h where r is the radius and h is the height.
We are given r = 5 and h = 2.5, plug those values in and simplify...
V = π(5²)(2.5)
V = π(25)(2.5)
V = 62.5π
Answer:
c. confidence/probability
Step-by-step explanation:
The margin of error of a confidence interval is:
M = T*s.
In which T is related to the confidence level and s is the standard deviation of the sample.
In which
z is the zscore that has a pvalue of
.
Before the sample is chosen
We choose our confidence level, which will determine the value of T. So the first answer is confidence.
After the sample is chosen
We are 95% sure that the true mean is in the sample. So the second answer is probability.
So the correct answer is:
c. confidence/probability
Answer:
No.
Step-by-step explanation:
Substitute in the coordinate (0, 0) and the resultant expression is:
0 > 2(0) + 3
0 > 3
We know that this is false, so it is not a solution to that inequality.
