Answer:
For A: 2.208
For B: 2.9024
Step-by-step explanation:
To solve we will do the following:
For A:
no insured(x) claims(y) xy Var=total/(y-1)
2 1 2 0.08
2 1 2 0.08
1 0 0 0.64
Weighted average 0.8 0.16
a var - X -0.64
k mean/a -1.25
Z (credibility) 1/(1+k) 0.444
no of claims for next year (y=4)
= 0.44*4 + 0.56*0.8
= 2.208
For B:
no insured(x) claims(y) xy Var=total/(y-1)
0 0 0 0
3 6 12 12
2 3 6 2
Weighted average 2.4 3.5
a var - X 1.1
k mean/a 2.18
Z (credibility) 1/(1+k) 0.314
no of claims for next year (y=4)
0.314*4 + 0.686*2.4
= 2.9024
1+ r belongs inside the parenthesis
so (0.95) = 1+r
r = 0.95-1 =
r = -0.05
since r is a negative number this would be a decrease in subscribers
Answer:
I. y = |x + 4|
Step-by-step explanation:
Step-by-step explanation:
we know about vertical angels that are equal
so <2=<4
(in fact they are congruent angles)
we found those only from the definition of vertical angles.
