They all have three sides, im really smart
Answer:
1.83%
Step-by-step explanation:
For the expected value of 4 cases per 1000 children. We can use a formula for Poisson distribution to calculate the probability that none of the 1000 students would contract the flu:
So the probability of this to happens is 1.83%
(3n-2) x (4n+1) =0
All you need to do is to find what value of n makes each factor equal 0.
First Term:
3n-2 = 0
3n = 2
n = 2/3
Second Term:
4n+1 = 0
4n = -1
n = -1/4
n ={2/3, -1/4}
Here is the answer on how to graph the equation
Answer: 5
Step-by-step explanation: The median is the middle number in the data set when the data set is written from least to greatest.
Notice that our data set is already written from least to greatest.
1, 2, 2, 8, 9, 14
Notice that in this data set, there is no middle number directly because 2 and 8 fall directly in the middle. In this situation, we take the average of these two middle numbers and divide their sum by 2.
Since 2 and 8 are the numbers that appear in the middle, we add them.
2 + 8 gives us 10.
Now we divide 10 by 2 to get 5.
So the median of this data set is 5.
