Answer:

  $142.32, profit on sale of the policy

Step-by-step explanation:

You want to know the expected value of a $280,000 life insurance policy sold for $270, if the probability the insured will live for the year is 0.999544.

The insurance company expects to have to pay the $280,000 death benefit for 0.000456 of the policies issued. That means their expected payout on any one policy is ...

  0.000456 × $280,000 = $127.68

The company gets a premium of $270 for the policy, so the expected value of the policy to the company is ...

  $270 -127.68 = $142.32

The expected value of the policy to the company is $142.32.

This represents its profit from sale of the policy.

__

Additional comment

Of course, the company has expenses related to the policy, perhaps including a commission to the agent selling it, and expenses related to handling claims. That is to say that not all of the difference between the premium and the average death benefit is actually profit. It is what might be called "contribution margin."

The sum is given by -  f(y) = 4(y -1).

We have the following expression -

(y + 5) + (3y - 9)

We have to evaluate the above sum.

Now -

f(x) + g(x) = 3x + 9 - (6 - x)  

f(x) + g(x) = 3x + 10 - 6 + x

f(x) + g(x) =  4x + 4

f(x) + g(x) = 4(x + 1)

According to the question, we have -

(y + 5) + (3y - 9)

Assume that the sum is represented by the function f(y).

Solving, we get -

f(y) = y + 5 + 3y - 9

f(y) = y + 3y + 5 - 9

f(y) = 4y - 4

f(y) = 4(y - 1)

Hence, the sum is given by -  f(y) = 4(y -1).

Answer:

Since f(-1) = 0 and f(-2) = 0, we can set up two equations:

(-1)³ + p(-1)² - q(-1) - 4 = 0

(-2)³ + p(-2)² - q(-2) - 4 = 0

Simplifying each equation, we get:

-1 + p - q - 4 = 0

-8 + 4p - 2q - 4 = 0

Simplifying further, we get:

p - q = 5

2p - q = 6

Solving for p and q, we can add the two equations together to eliminate q:

p - q + 2p - q = 5 + 6

3p - 2q = 11

Then, we can substitute the value of q from the first equation into this equation to solve for p:

3p - 2(q + 5) = 11

3p - 2q - 10 = 11

3p - 2q = 21

3p - 2(5 + p) = 21

p - 10 = 7

p = 17

Substituting this value of p into either equation for q, we get:

q = p - 5 = 12

Therefore, the coefficients are p = 17 and q = 12. To factor the expression, we can use synthetic division or long division. Using synthetic division, we get:

-1 | 1 17 -12 -4

|__ -1 -16 28

1 1 12

This gives us the factorization:

f(x) = (x + 1)(x² + x + 12)

To find the solutions, we can use the quadratic formula on the quadratic factor:

x = (-1 ± sqrt(1 - 4(1)(12))) / 2(1)

x = (-1 ± sqrt(1 - 48)) / 2

x = (-1 ± sqrt(-47)) / 2

x1 = (-1 + i(sqrt(47))) / 2

x2 = (-1 - i(sqrt(47))) / 2

Therefore, the solutions are x1 = (-1 + i(sqrt(47))) / 2, x2 = (-1 - i(sqrt(47))) / 2, and x3 = -1.

Answer:

Step-by-step explanation:

(A)

(i) The optimal price you should post for each of LP and LH is in two combinations:

COMBINATION 1:

$600 for LP and $300 for LH

This combination fetches you $900 (which is the maximum you can earn in this scenario, because each buyer will only buy 1 type of link)

COMBINATION 2:

$500 for LP and $400 for LH

This combination also fetches you $900 revenue.

Why these price combinations? Because you have two constraints:

1. Each buyer is only interested in 1 unit of 1 link type

2. You as a producer or seller, wish to maximize revenue

These are the constraint functions!

(ii) At Price Combination 1,

Mr. A will purchase 1 unit of LP while Mr. B will purchase 1 unit of LH

At Price Combination 2,

Mr. A will purchase 1 unit of LH while Mr. B will purchase 1 unit of LP

(B)

(i) If you could identify each buyer and make targeted offers (offers targeted at each buyer's WTP) you would offer their maximum WTP price to them for each commodity.

That's the 'economic agent' way of thinking; to bargain favourably or in your own case, to maximize revenue.

So, you'll charge Mr. A $600 for LP and $400 for LH

Charge Mr. B $500 for LP and $300 for LH

(ii) Although you thought economically, this particular set of potential customers are price-driven instead of taste-driven so instead of them to purchase LP which is generally more expensive (or of a higher quality), each of them would buy LH!

Your revenue here will now be $400 + $300 = $700

The probability that the proportion of teenagers in the sample who play video games on their phone is less than 0.497 is 0.6049

We can use the normal approximation to the binomial distribution to solve this problem, since

The mean of the sample proportion is equal to the population proportion, which is 0.48.

The standard deviation of the sample proportion is given by:

σ = √[(p * (1 - p)) / n]

σ = √[(0.48 * 0.52) / 60]

σ ≈ 0.064

To find the probability that the proportion of teenagers in the sample who play video games on their phone is less than 0.497, we can standardize this value using the z-score:

z = (0.497 - 0.48) /0.064

z = 0.266

Using a standard normal distribution calculator, we can find that the probability of getting z-score < 0.266

We have

P = 0.6049

Therefore, the probability of the proportion is approximately 0.6049

\(\large \sf \underline{Problem:}\)

The person is lifting a heavy box using a lever what is the purpose of the lever in the situation?

====================================

\(\large \sf \underline{Answer:}\)

to reduce the force needed to lift the box and change the direction of the force.

====================================

\(\large \sf \underline{Explanation:}\)

1. "A lever consists of a rigid bar that is able to pivot at one point. This point of rotation is known as the fulcrum. A force is applied at some point away from the fulcrum (typically called the effort)."

By this definition, we know that force is needed to lift an object using a lever.

2. "When the input and output forces are on opposite sides of the fulcrum, the lever changes the direction of the applied force. This occurs only with first-class levers. When both the input and output forces are on the same side of the fulcrum, the direction of the applied force does not change"

For example, on a sew saw, if a force is applied on one end, you on the other side/end would go up, meaning a change in direction.

3. Lastly, we know a lever is typically used to reduce work, in other words, the force needed to move something.

Basically, if we were to put a lever into an equation:

reduced force + change in direction = lever

(the expection) unless load and force are on the same side, there will be no change in direction.

For example, if you and your friend sit on the same side of a sew saw, the sew saw would not go up or down, meaning no change in direction.

So if not stated otherwise you can assume the load and force are on opposite sides. The purpose of a lever in that situation would be to reduce the force needed to lift the box and change the direction of the force.

*While reading my explanation, it may be helpful to look up a diagram containing a lever, with a load, fulcrum, and applied force.

Answer:

X=11 trust me on my mom

Step-by-step explanation:

First get x on its own:

Subtract 3 from each side

y - 3 = 2x

Divide through by 2

y/2 - 3/2 = x

or x = y/2 - 3/2

Now simply switch labels: x↔y

y = x/2 - 3/2

Answer:

\(y=\frac{x}{2}+\frac{3}{2}\)

Step-by-step explanation:

To find inverse of an equation, replace the variables x with y and y with x:

x = 2y - 3

Now we get it in slope-intercept form:

x = 2y - 3

Add 3 to both sides.

x + 3 = 2y

Divide both sides by 2.

\(\frac{x}{2}+\frac{3}{2}=y\)

Swap left and right sides.

\(y=\frac{x}{2}+\frac{3}{2}\)

And this is the inverse of the equation y = 2x - 3.

We can iterate through a list using two nested loops to check for pairs that add up to the target.

The formula for finding pairs that add up to the target is as follows:

For each element (x) in the list, loop through the rest of the list (y) and check if x + y = target

Let's say we have a list of numbers [1,2,3,4] and the target is 5.

We will start by checking if 1 + 4 = 5. Since it does, we have found our first pair.

Then, we will move on to 2 + 3 = 5. This is also true, which gives us our second pair.

We have now looped through the entire list and found all pairs that add up .

Let's denote the amount Jolene invested at 3 percent interest as 'x' dollars. Since she put twice as much in the lower-yielding account, the amount she invested at 9 percent interest would be '2x' dollars.

To calculate the interest earned from each account, we'll use the formula: Interest = Principal × Rate × Time.

For the 3 percent interest account:

Interest_3_percent = x × 0.03

For the 9 percent interest account:

Interest_9_percent = 2x × 0.09

We know that the total annual interest is $3120, so we can set up the equation:

Interest_3_percent + Interest_9_percent = 3120

Substituting the above equations, we have:

x × 0.03 + 2x × 0.09 = 3120

Simplifying the equation:

0.03x + 0.18x = 3120

0.21x = 3120

Dividing both sides of the equation by 0.21:

x = 3120 / 0.21

x = 14857.14

Therefore, Jolene invested approximately $14,857.14 at 3 percent interest and twice that amount, $29,714.29, at 9 percent interest.

Answer:

Step-by-step explanation:

X is the amount invested at 6%

Y is the amount invested at 9%

0.06X + 0.09Y = 4998

X = 2Y

0.06(2Y) + 0.09Y  = 4998

.12Y + 0.09Y = 4998

0.21Y = 4998

21Y = 499800

Y = 499800/21 = 23800

So X = 2*23800 = 47600

$47,600 is invested at 6% and $23800 is invested at 9%
