x is the independent variable.

y is the dependent variable.

-3 is the rate of change (slope).

-7 is the initial value.

Step-by-step explanation:

The form of the linear relation is y = m x + b, where

  • m is the rate of change (slope)
  • b is the initial value(value of y at x = 0)
  • x is the independent variable
  • y is the dependent variable

∵ The equation of the line is y = -3 x - 7

- Compare it with the form above

∴ m = -3

∵ m is the rate of change

∴ The rate of change is -3

∴ b = -7

∵ b is the initial value

∴ The initial value is -7

∵ y depends on x

∴ x is the independent variable

∴ y is the dependent variable

x is the independent variable.

y is the dependent variable.

-3 is the rate of change (slope)

-7 is the initial value.

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.

Mama L [17]
Okay well the way I do it is like this. When ever the next hour hits 10 minutes that is one hour then add the minutes left. So from 7:10a.m. to 6:10p.m. is 11 hours. Now the rest of the minutes. 6:35 -6:10=:25. So she has been away from the house for 11 hours and 25 minutes
