What is the expected value for the insurance company?

E(x) = 0.9986*161 + 0.0014*(-99839) = $21.00

Step-by-step explanation: Ur welcome

There is a 0.9986 probability that a randomly selected 30 year old male lives through the year. A life insurance company charges $161 for insuring that the male lives through the year. If the male does not survive the year, the policy pays out $100,000 as a death benefit.

Determine the equation of the circle graphed below.

sergij07 [2.7K]

Answer:

Equation = (x - 6 )² + ( y + 3 )² = 9

Step-by-step explanation:

The circle passes through ( 6, 0) and ( 6 , -6)

They are the coordinates of the diameter.

Using this we can find the centre of the circle.

<u>Find the centre of the circle.</u>

Centre of the circle is the mid- point of (6, 0) and ( 6, -6)

$Centre = (\frac{x_1+x_2}{2} , \frac{y_1 + y_2}{2})$

$=(\frac{6 + 6}{2}, \frac{0 + (-6)}{2})\\\\=(6, -3)$

<u>Find the radius of the circle.</u>

$Radius = \frac{Diameter }{2}$

Diameter is the distance between the points (6 , 0) and ( 6, - 6)

$Diameter = \sqrt{(x_2 - x_1)^2+ (y_2 - y_1)^2\\}$

$=\sqrt{(6-6)^2 + (-6 -0)^2}\\\\=\sqrt{0 + 36} \\\\= 6$

Therefore,

$Radius ,r = \frac{6}{2} = 3$

<u>Standard equation of a circle:</u>

<u></u> $(x - a)^2 + (y - b)^2 = r^2 \ where \ (a , b) \ is \ the\ centre \ coordinates.$ <u></u>

Therefore , equation of the circle ;

$(x - 6)^2 + (y + 3)^2 = 3^2\\\\(x -6)^2 + (y + 3)^2 = 9$

5 ports Use absolute value to express the distance between -12 and -15 on the number line. |-12 - (-15) = -27

zloy xaker [14]

Answer:

$Distance = 3$

Step-by-step explanation:

Given

-12 and -15

Required

Solve the difference

The question you posted included the solution. However, the solution is incorrect;

The absolute difference is represented as:

$Difference = \vert a - b \vert$

In this case:

$a = -12$

$b = -15$

So, the distance is calculated as:

$Distance = |-12 - (-15)|$

Open bracket

$Distance = |-12 +15|$

$Distance = |3|$

$Distance = 3$
