If a 60 year old buys a $1000 life insurance policy at a cost of $50 and has a probability of 0.954 of living to age 61 find the
ANTONII [103]

Answer:

The expectation of the policy until the person reaches 61 is of -$4.

Step-by-step explanation:

We have these following probabilities:

0.954 probability of a loss of $50.

1 - 0.954 = 0.046 probability of "earning" 1000 - 50 = $950.

Find the expectation of the policy until the person reaches 61.

Each outcome multiplied by it's probability, so:

E = -0.954*50 + 0.046*950 = -4

The expectation of the policy until the person reaches 61 is of -$4.

Carmen simplifies the expression (4 y 8 x 6) 25 (4 x 6 y 7). The coefficient of the variable y in her simplified answer is 4. 6.
Sever21 [200]

Carmen simplifies the expression and gets the coefficient of y is 10. Thus, the correct option is C.

<h3>What is simplification?</h3>

Simplification is to make something easier to do or understand and to make something less complicated.

Given

Carmen simplifies the expression \rm (4 y + 8 x + 6) + 25 + (4 x  +6 y +7).

We can add x term with x, y term with y, and constant with constant.

On simplifying, we have

\rm (4 y + 8 x + 6) + 25 + (4 x  +6 y +7)\\\\12x + 10y + 38

Thus, the coefficeint of y is 10.

More about the simplification link is given below.

Find the multiplicative inverse of 3 − 2i. Verify that your solution is corect by confirming that the product of
leonid [27]

Answer:

\frac{3}{13} + \frac{2i}{13}

Step-by-step explanation:

The multiplicative inverse of a complex number y  is the complex number z such that (y)(z) = 1

So for this problem we need to find a number z such that

(3 - 2i) ( z ) = 1

If we take z = \frac{1}{3-2i}

We have that

(3- 2i)\frac{1}{3-2i} = 1 would be the multiplicative inverse of 3 - 2i

But remember that 2i = √-2 so we can rationalize the denominator of this complex number

\frac{1}{3-2i } (\frac{3+2i}{3+2i } )=\frac{3+2i}{9-(4i^{2} )} =\frac{3+2i}{9-4(-1)} =\frac{3+2i}{13}

Thus, the multiplicative inverse would be \frac{3}{13} + \frac{2i}{13}

The problem asks us to verify this by multiplying both numbers to see that the answer is 1:

Let's multiplicate this number by 3 - 2i to confirm:

(3-2i)(\frac{3+2i}{13}) = \frac{9-4i^{2} }{13}  =\frac{9-4(-1)}{13}= \frac{9+4}{13} = \frac{13}{13}= 1

Thus, the number we found is indeed the multiplicative inverse of  3 - 2i
