Answer:896.9
Step-by-step explanation:
Let x denotes excess premium over claims
, There are two possibilities
(i)Only husband survives
This can be possible with a possibility of 0.01
Claims=10,000
Premium collected
Thus x=1000-10,000=-9000
(ii)Both husband and wife survives
This can occur with a probability of 0.96
Here claims will be 0 as both survives
Premium taken=1000
thus x=1000
The probability that the husband survives is the sum of above cases
=0.96+0.01=0.97
Hence the desired conditional Expectation 
You can use the formula 2(a+b

This will get you 161.5 ft

Answer:

Step-by-step explanation:
We have to assume that the question is referring to the doubly-shaded length, the one that is 10 bright blue units long.
You can read the overall length of the shaded area as 5/4, from the markings.
For the next part, you need to count the number of units that are shaded bright blue (10) and the number that are shaded blue overall (15). As a fraction of those shaded blue overall, the ones shaded bright blue are 10/15 = 2/3.
So, the length shaded bright blue is 2/3 of the overall length of 5/4. It is represented by the product ...

Answer: length = 28 feet
Width = 16 feet
Step-by-step explanation:
Let L represent the length of the rectangular garden.
Let W represent the width of the rectangular garden.
The formula for determining the perimeter of a rectangle is expressed as
Perimeter = 2(L + W)
The perimeter of a garden is 88 feet. This means that
2(L + W) = 88
Dividing through by 2, it becomes
L + W = 44 - - - - - - - - - - - -1
The length is 12 feet greater than the width. This means that
L = W + 12
Substituting L = W + 12 into equation 1, it becomes
W + 12 + W = 44
2W + 12 = 44
2W = 44 - 12
2W = 32
W = 32/2
W = 16
L = W + 12 = 16 + 12
L = 28
