Answer:

And now if we solve for X we have this:


So then we conclude that they should be charge $25.25 for the insurance in order to have a profit of $25.
Step-by-step explanation:
Previous concepts
In statistics and probability analysis, the expected value "is calculated by multiplying each of the possible outcomes by the likelihood each outcome will occur and then summing all of those values".
For this case we can use the definition of expected value given by:

Solution to the problem
For this case we know that the probabiity of maximum claim is 0.01, so then the probability of no maximum claim by the complement rule is 1-0.01=0.99
And we know that the plan with maximum claim gives an amount of $5000
Let X the charge for the premium insurance
We also know that the profit or the expected value would be 25 for the company
If we apply the concept of expected value we have this:

And now if we solve for X we have this:


So then we conclude that they should be charge $25.25 for the insurance in order to have a profit of $25.
Answer:
6) b(3a^4-5c³)
7) 3x³yz(2x+5y)
8) 4a²b²c³(2bc-3a)
9) 4xy(2y+7z-1)
10) 2mn(5n²+2m-3n)
Step-by-step explanation:
6) Factor out the b and you get b(3a^4-5c³)
7) Factor out the 3x³yz and you get 3x³yz(2x+5y)
8) Factor out the 4a²b³c³ and you get 4a²b²c³(2bc-3a)
9) Factor out the 4xy and you get 4xy(2y+7z-1)
10) Factor out the 2mn and you get 2mn(5n²+2m-3n)
One may note you never quite asked anything, now, assuming simplification,
X(x+2) = 48
x^2 + 2x = 48
x^2 + 2x - 48 = 0
*Use quadratic formulae*
x = 6
Numbers are 6 and 8
