Step-by-step explanation:
Slope/Gradient = 
P = (-8 , 3) (x1, y1)
Q = (-6 , 2) (x2, y2)
Slope =

Answer:
Step-by-step explanation:
Expected value of the bet =
<h3>
P(you make the correct draw) * 40 + P(you do not make the correct draw) * (-10) = </h3>
(4/52)(4/51)(4/50) * 40 + (1 - (4/52)(4/51)(4/50)) * (-10) =
(64/132600) * 40 + (1 - 64/132600) *(-10) =
64/3315 + (132536/132600) * (-10) =
64/3315 - (132536/13260) =
64/3315 - 33134/3315 =
-33070/3315 =
-9.97586726998 =
-$9.98, rounded to the nearest cent
(i.e., the expected value of the bet is a loss of $9.98)
Answer:
c) Either A or B or both occur.
Step-by-step explanation:
Suppose that we have two events
Event A
Event B
We have that:
In which a a happens and b does not and 
is the probability that aboth events happen
By the same logic, we have that:
The union of events A and B is:
Which includes either one of them or both.
So the correct answer is:
c) Either A or B or both occur.
Answer:
The type of association between x and y are inversely proportional
Step-by-step explanation:
Solution:
Here the x value increase, the y value decrease which implies that x is inversely proportional to y
