Answer:

Expected profit policy 1 = $40

Expected profit policy 2 = $20

Expected profit policy 3 = $10

Step-by-step explanation:

X values | Probability P(x)

0 | 0.80

1,000 | 0.08

5,000 | 0.10

10,000 | 0.02

A particular company offers three different policies:

Policy 1: $200 deductible with a $780 premium

Policy 2: $500 deductible with a $700 premium

Policy 3: $1000 deductible with a $590 premium

The company pays X - Y in damages if X > Y and 0 otherwise.

So the expected profit is given by

Expected profit = Premium amount - Expected payout

Expected profit = Premium amount - [ (X - deductible) × P(x) ]

Expected profit Policy 1:

E(x) = $780 - [ 0×0.80 + (1,000 - 200)×0.08 + (5,000 - 200)×0.10 + (10,000 - 200)×0.02 ]

E(x) = $780 - [ 0 + 64 + 480 + 196 ]

E(x) = $780 - $740

E(x) = $40

Expected profit Policy 2:

E(x) = $700 - [ 0×0.80 + (1,000 - 500)×0.08 + (5,000 - 500)×0.10 + (10,000 - 500)×0.02 ]

E(x) = $700 - [ 0 + 40 + 450 + 190 ]

E(x) = $700 - $680

E(x) = $20

Expected profit Policy 3:

E(x) = $590 - [ 0×0.80 + (1,000 - 1,000)×0.08 + (5,000 - 1,000)×0.10 + (10,000 - 1,000)×0.02 ]

E(x) = $590 - [ 0 + 0 + 400 + 180 ]

E(x) = $590 - $580

E(x) = $10

Therefore, the expected profits for the three policies are:

Expected profit policy 1 = $40

Expected profit policy 2 = $20

Expected profit policy 3 = $10

How do i figure out the degrees?

liraira [26]

Answer:

41°

Step-by-step explanation:

This problem involving the Law of Cosines has been mostly worked for you. The value of the cosine is the solution to the remaining one-step linear equation. The inverse cosine function (cos⁻¹ or arccos) is used to find the angle from the value of the cosine.

-1125 = -1500·cos(A)

cos(A) = -1125/-1500 = 3/4 . . . . . divide by -1500 (this is the one step)

A = arccos(3/4) ≈ 41.4096°

The angle formed by the lines to the lampposts is about 41°.

Additional comment

If you find the angle using the ACOS( ) function of a spreadsheet, you will always get the result in radians. Most calculators offer the choice of units for angles, so be sure you set the mode appropriately.

In the calculator screenshot, there is a decimal point in the fraction to force the angle result to be displayed as a numerical value. Otherwise, this calculator shows cos⁻¹(3/4), which isn't terribly helpful.

Below you will find the question is broken down into two parts. The first is asking you to solve equations and show your work. T

Schach [20]

Step-by-step explanation:

Equation (1) is :

x+2=5

Subtract 2 from both sides,

x+2-2=5-2

x=3

Equation (2) is :

2n+5=n

Taking like terms together,

2n-n=-5

n=-5

Equation (3) is :

5(x+2)-7=3x+5

⇒5x+10-7=3x+5

taking like terms together,

5x-3x=5-10+7

⇒2x=2

x=1

Hence, x =3, n = -5 and x = 1 is the required answer.

DNS ~ ARH What is the value of x?

ZanzabumX [31]

Corresponding angles are congruent (same measure)So in the figure above, the angle P=P', Q=Q', and R=R'.Corresponding sides are all in the same proportionAbove, PQ is twice the length of P'Q'. Therefore, the other pairs of sides are also in that proportion. PR is twice P'R' and RQ is twice R'Q'.
so the value of x :
x / 110 = 21.6 / 72
solve for x
x = 33
