Answer:
And we can find this probability with the complement rule and with the normal standard table and we got:
Step-by-step explanation:
Let X the random variable that represent the patient recovery time of a population, and for this case we know the distribution for X is given by:
Where
and
We are interested on this probability
And we can solve this problem using the z score formula given by:
And using this formula we got:
And we can find this probability with the complement rule and with the normal standard table and we got:
Answer:
5
Step-by-step explanation:
The midpoint of segment AB is (1, 1).
Substituting these coordinates into the equation of the line,
![2(1)+3(1)-k=0 \\ \\ 5-k=0 \\ \\ k=5](https://tex.z-dn.net/?f=2%281%29%2B3%281%29-k%3D0%20%5C%5C%20%5C%5C%205-k%3D0%20%5C%5C%20%5C%5C%20k%3D5)
A because mean is average.
Answer:
E
Step-by-step explanation:
There are both red and green marbles in the jar. The answer cannot be A or D because that would mean that there's 1.14% or 1.04% green marbles. But we know that there's less than that in the and bag. And there are also red marbles. B and F do not work because there can't be a negative amount of marbles in the bag.
