For the experimental probability you must record the data that you collect by flipping your own coin, then you must find the probability of landing on either side. For example, the theoretical probability for the coin toss it will be 50% chance for either side. For the experimental it depends on your own results.

A life insurance company sells a $100,000 one year term life insurance policy to a 30-year old male for $475. The probability th
laila [671]

Answer:

The expected value for the insurance company is $392.20.

Step-by-step explanation:

The expected value of a random variable, <em>X</em> is:

E(X)=x\cdot P(X)

It is provided that a life insurance company sells a $100,000 one year term life insurance policy to a 30-year old male for $475.

The probability that the male survives the year is, P(S) = 0.999172.

Then the probability that the male does not survives the year is:

P (S') = 1 - P (S)

        = 1 - 0.999172

P (S') = 0.000828

The amount the company owes the male if he survives is, S = $475.

The amount the company owes the male if he does not survives is,

S' = $475 - $100,000 = -$99525.

Compute the expected value for the insurance company as follows:

E(\text{Insurance Company})=S\cdot P(S)+S'\cdot P(S')

                                     =(475\times 0.999172)+(-99525\times 0.000828)\\=474.6067-82.4067\\=392.20

Thus, the expected value for the insurance company is $392.20.

One fifth of a number plus five times that number is equal to seven times the number less 18. find the number.
Schach [20]
OK.  First we have to figure out names for all the numbers you mentioned.

The mysterious number . . . . . call it Q
One fifth of the number . . . . . 0.2 Q
Five times the number . . . . . . 5 Q
Seven times the number . . . . 7 Q

(One fifth plus five times the number) . . . 5.2 Q
(Seven times the number less 18) . . . . . . 7 Q - 18

You said that these last two things are equal, 

so I can write . . . . . . . . . . . . . . . . . .  7 Q - 18  =  5.2 Q

Now, subtract  7Q  from each side . . .  -18 = -1.8 Q

Divide each side by  -1.8 . . . . . . . . . .  10 = Q

dezoksy [38]
First, you need no find out how much is 45% of 15,00. ( it is $6,750)
so then you need to multiply that number by 2 
them you get $13,500
so his parents saved up $13,500
