Answer:
Step-by-step explanation:
From Bayes' theorem is stated mathematically as the following equation:[2]
{\displaystyle P(A\mid B)={\frac {P(B\mid A)\,P(A)}{P(B)}},}
where A and B are events and P(B) ≠ 0.
P(A) and P(B) are the probabilities of observing A and B without regard to each other.
P(A | B), a conditional probability, is the probability of observing event A given that B is true.
P(B | A) is the probability of observing event B given that A is true.
At this point, go through the attached file before you continue with part B.
Part B)
P(silver) = P(silver from SS)+P(silver from GS)
note P(SS)=P(GG)=P(GS) = 1/3
P(silver from SS) = 1
P(silver from GS) = 1/2
hence
P(Silver from SS) = 1/3
P(Silver from GS) = 1/3 *1/2
P(Silver) = 1/3*1+1/3*1/2
required probability = P(Silver from SS)/P(Silver) = 2/3
Answer:
(-(23/3), -(11/3))
Step-by-step explanation:
x=y-4
2x-5y=3
=====
2x-5y=3
2(y-4)-5y=3 [Substitute (y-4) for x in the 2nd equation]
2y - 8 -5y = 3
-3y = 11
y = -(11/3)
y = -3 2/3
Use this in the 1st equation to find x:
x=y-4
x=-(11/3)-4
x = -(11/3)-(12/3)
x = -(23/3)
x = -7 2/3
See graph attached.
Answer:
This does represent an exponential function , because his savings increase by a constant rate
Step-by-step explanation:
Let
x -----> the number of weeks
y ----> the amount saved
In this problem we have a exponential function of the form
where
a is the initial value
b is the base
r is the rate of change
where
---- because he doubles the amount each week
---->
substitute
therefore
This does represent an exponential function , because his savings increase by a constant rate
