Answer:
Sequence .
Step-by-step explanation:
Given : sequence 3/4, 6/5, 9/6, 12/7, 15/8 .
To find : The general term for the sequence.
Solution : We have given that 3/4, 6/5, 9/6, 12/7, 15/8 .
Here numerators are 3 , 6, 9 , 12, 15
Denominators are 4 ,5 , 6, 7, 8.
We can see in numerators all are multiple of 3
As, 3 × 1 , 3 × 2, 3 × 3 ...... etc
We can write it as : 3n
Denominator are 3 +1 , 3 +2 , 3 +3 ..........etc
We can write it as 3 +n
So , sequence become
Therefore, sequence .
payout probability distribution:
Answer:
The expected value is $3.95
Step-by-step explanation:
Here, we want to get the expected value
Mathematically, what we have to do here is to multiply each of the probabilities by the pay out value, before we proceed to add up
We have this as;
0(0.5) + 0.2(5) + 0.15(8) + 10(0.1) + 15(0.05)
= 0 + 1 + 1.2 + 1 + 0.75 = 3.95
Answer:
3.00
Step-by-step explanation:
Given that :
Payout(X) : ___ 0 ___ 4 ___ 6 ____ 8 _____ 10
Probability (p(x) 0.5 _ 0.2 __0.15 __0.1 ___ 0.05
Expected value :E(X) = ΣX* p(x)
E(X) = (0*0.5) + (4*0.2) + (6*0.15) + (8*0.1) + (10*0.05)
E(X) = 3
Expected value = 3.00
