Answer:
The probability that the sample will contain exactly 0 nonconforming units is P=0.25.
The probability that the sample will contain exactly 1 nonconforming units is P=0.51.
.
Step-by-step explanation:
We have a sample of size n=4, taken out of a lot of N=12 units, where K=3 are non-conforming units.
We can write the probability mass function as:
where k is the number of non-conforming units on the sample of n=4.
We can calculate the probability of getting no non-conforming units (k=0) as:
We can calculate the probability of getting one non-conforming units (k=1) as:
It’s a becuz when the the yes no u
Answer:
(Slope intercept form)
(Slope point form)
Step-by-step explanation:
The slope of the line can be calculated as following:
The the equation of the line in slope point form is:
Where (
,
) is a point of the line.
Then you must susbtitute the point given and the slope and you obtain:
The intercept form is:
Where b is the y-intercept.
Solve for y from the equation of the line in slope point form obtained above, then:
Answer:
The relationship is positive.
The model predicts a score of 60.
Not sure what part b is.
Step-by-step explanation:
Since while the money spent on advertising increases while the items sold increases, we have a positive relation between both variables.
By looking at where 30 is on the graph, we can see it lines up with 60,the middle between $40 and $80 on the y axis and so we know this is the cost associated with this value.
