Find
R(V)
- p(x)×x
- x(-3/2x+112)
- -3/2x²+112x
Now
Find vertex x coordinate
Put in equation
- y=-3/2(-37.3)²+112(-37.3)
- y=-2086.9-84+4177.6
- y=$6264.6
- y=$62.64M
As a is negative parabola is facing downwards hence vertex is minimum .
So minimum value is $62M which is far more than given .
Answer:
The Emancipation Proclamation is the document that changed the purpose of the Civil war from one of states' rights to that of slavery.
Step-by-step explanation:
The Emancipation Proclamation is the document that changed the purpose of the Civil war from one of states' rights to that of slavery.

Step-by-step explanation:
To solve this problem we use the formula of combinations
Where n is the total number of students that can be chosen and you choose r from them.
So
Note that in this case the order in which the 4 students are chosen does not matter.
Then
Answer:
44
Step-by-step explanation:
-×-=+
11×4=44
so it's equal to =+44
Answer: 0.31 or 31%
Let A be the event that the disease is present in a particular person
Let B be the event that a person tests positive for the disease
The problem asks to find P(A|B), where
P(A|B) = P(B|A)*P(A) / P(B) = (P(B|A)*P(A)) / (P(B|A)*P(A) + P(B|~A)*P(~A))
In other words, the problem asks for the probability that a positive test result will be a true positive.
P(B|A) = 1-0.02 = 0.98 (person tests positive given that they have the disease)
P(A) = 0.009 (probability the disease is present in any particular person)
P(B|~A) = 0.02 (probability a person tests positive given they do not have the disease)
P(~A) = 1-0.009 = 0.991 (probability a particular person does not have the disease)
P(A|B) = (0.98*0.009) / (0.98*0.009 + 0.02*0.991)
= 0.00882 / 0.02864 = 0.30796
*round however you need to but i am leaving it at 0.31 or 31%*
