Answer:
-$500
Step-by-step explanation:
The expected value of a payment from the policy is ...
$500,000 × 0.002 = $1000
Since the business pays $1500 for the policy, the expected value to the business is ...
$1000 - 1500 = -$500 . . . per year
_____
Of course, the expected value to the insurance company is $500 per year.
_____
We have computed on the basis of 1 claim per year. If we consider the possibility of multiple independent claims, then the expected payment from the insurance goes up by a factor of 1/(1 -0.002) ≈ 1.002004008016.... This has the effect of increasing the expected value by $2.00 per year to -$498.
Answer:
D
Step-by-step explanation:
the answer is d because it's the 3 and 5/8ths per pie this it is multiplied by x.
X²+15x+36<0
at first solve quadratic equation
D=b²-4ac= 225-4*1*36= 81
x=(-b+/-√D)/2a
x=(-15+/-√81)/2= (-15+/-9)/2
x1=(-15-9)/2=-12
x2=(-15+9)/2=-3
we can write x²+15x+36<0 as (x+12)(x+3)<0
(x+12)(x+3)<0 can be 2 cases, because for product to be negative one factor should be negative , and second factor should be positive
1 case) x+12<0, and x+3>0,
x<-12, and x>-3
(-∞, -12) and(-3,∞) gives empty set
or second case) x+12>0 and x+3<0
x>-12 and x<-3
(-12,∞) and (-∞,-3) they are crossing , so (-12, -3) is a solution of this inequality
.40 or 40%. The fraction 4/10 is equal to 40/100.
