Answer:
If you did it three times it would be 4 1/2. If you wanted to make it at least 4 3/4 then you would need to do 1 1/2 4 times.
Step-by-step explanation:
Answer:
330(D)
Step-by-step explanation:
So lets go over what we know:
#1: 44 out of 80 people think they have a average fitness level.
#2: 80 out of the 600 people in the school were surveyed.
Using what we know, lets try and find the answer.
So lets divide the total amount of people, by the amount of people that took the survey:
600/80
=
7.5
Ok, so now we know that we need to take 7.5 surveys to find out what all the students think of their fitness level.
Now lets take teh amount of people in a single survey, with average fitness(44), and multpliy it by how many surveys are needed for the whole school(7.5):
44*7.5
=
330
This is the amount of people in the whole school who think they have an average fitness level.
I hope this helps! :)

Answer:
Step-by-step explanation:
Given that:
X(t) = be the number of customers that have arrived up to time t.
... = the successive arrival times of the customers.
(a)
Then; we can Determine the conditional mean E[W1|X(t)=2] as follows;
Now 
(b) We can Determine the conditional mean E[W3|X(t)=5] as follows;
Now; 
(c) Determine the conditional probability density function for W2, given that X(t)=5.
So ; the conditional probability density function of 
given that X(t)=5 is:
The statement which best describes the association between the variables X and Y is the <em>moderate positive association</em>. It is observable that the values of X and Y are increasing, however, not in a perfect manner as there are some minor deviations. But nonetheless, the direction is clear and the values are close to each other so they have a moderate positive association.
