Answer:
1.0.008
2. 0.0307
3. 12
Step-by-step explanation:
Probability p=0.2
Given that x + k = 3 and k = 3 hence x=0 where k is sales and x is successful visits
1
Required probability =P(x=0)
Using negative binomial distribution
=
=
2 ) Here , Given that , x + k = 5 and k = 3 hence x=5-3=2
Required probability =P(X=2)
Using negative binomial distribution
=
3 ) Given : k = 3 p = 0.2 q = 1 - p = 1 - 0.2 = 0.8
Answer:
A.)
In 2 months, Rex is 6 pounds and in 8 months he's 9lbs (from 2 to 8 is 6 months). So I inferred that to get to 9lbs from 6lbs is to go 0.5 pounds more each month.
B.)
2 = 6
3 = 6.5
4 = 7
5 = 7.5
6 = 8
7 = 8.5
8 = 9
C.) I don't think I can create a linear model here. So I don't think its nessesary.
D.)
If Rex were to grow over the expected 6 months, it would be 45.
So, we have the points. Here are the graphs:
So, the answer is d
(f+g)(x)=f(x)+g(x)
=-3x-5+4x-2
=x-7.Ans,,
