Answer: 0.6
Step-by-step explanation:
The probability formula to find p(B/A) is :
P(B/A) = p(A n B) / p(B)
Which means that A is contain in B and p(A n B) is p(A)
p(A n B)= p(A)=0.6 × 0.05 = 0.03
p(B)=0.05
Therefore
P(B/A) = p(A n B) / p(B)=p(A) / p(B)
P(B/A)=0.03 / 0.05
P(B/A)=0.6
I think so:
Your working out is probably just the same as my working out!

it's true cuz im corrrect
The answer is choice D
-----------------------------------------
Explanation:
We can rule out choice B and choice C which are y = 2.4^x and y = 3.5^x respectively. Why can we eliminate these? Because they are growth functions (the bases are larger than 1). The graph shown is a decay function. It goes downhill as you read it from left to right.
The answer is either choice A or choice D
If we plug in x = -2 into the equations for A and D, we get
y = 0.65^x = 0.65^(-2) = 2.36686
y = 0.32^x = 0.32^(-2) = 9.765625
The result for choice D is much closer to what the graph is showing. The graph appears to have the point (-2,11) on the curve. So that's why choice D is the best answer.
Note: the graph is a bit small and its not entirely clear which points are on this graph other than (0,1). So this is a bit of educated guesswork.
1) an = a1 + d*(n-1) => a20 = -4 + (-9)*19 = -4 - 171 = - 175
1) ---> C)
2) a81 = 20 + 4*80 = 340;
2) ---> A)
3) a12 = ?
3) ---> B) or D).
