The function that describes the profit earned from the sales of the bikes over a period of x years is: [tex]P(x) = 100x^3 + 6x^2 + 9x[/tex]. The Option A is correct.

The profit earned from the sales of the bikes can be calculated by subtracting the cost of manufacturing from the revenue earned. Therefore, the function that describes the profit earned can be represented as:

[tex]P(x) = S(x) - C(x)[/tex]

Substituting the given functions for S(x) and C(x), we get:

[tex]P(x) = (100x^3 + 6x^2 + 97x + 215) - (88x + 215)[/tex]

Simplifying this expression, we get:

[tex]P(x) = 100x^3 + 6x^2 + 9x.[/tex]

Answer:30

Step-by-step explanation:

a) The expected payout for the insurance company is $182.

b) If the insurance company wants to charge 15% over the expected payout, the insurance company should charge the insured $27.30.

In a game of chance, the expected payout is the expected value of the game minus the cost.

For the insurance company, the expected payout is the probability-weighted value of the insurance undertaking.

The expected payout is the product of the amount to be paid to the insured family and the probability or chance of the insured dying.

The amount the insured family will receive = $130,000

The chance of the insured dying = 0.0014

The expected payout = $182 ($130,000 x 0.0014)

Charge over the expected payout = 15%

The amount the insurance company should charge the person = $27.30 ($182 x 15%)

The result of the given polynomial division (2x^(3)+4x^(2)+7x+5 divided by x+1) using long division method is 2x^(2) + 2x + 5.

To find the result of the given polynomial division using long division method, we need to follow the steps below:

Step 1: Write the dividend and the divisor in long division form.

        ______________________
x + 1  |  2x^(3) + 4x^(2) + 7x + 5

Step 2: Divide the first term of the dividend by the first term of the divisor. In this case, 2x^(3)/x = 2x^(2). Write the result above the dividend.

        2x^(2)  _______________
x + 1  |  2x^(3) + 4x^(2) + 7x + 5

Step 3: Multiply the result by the divisor and write the product under the dividend.

        2x^(2)  _______________
x + 1  |  2x^(3) + 4x^(2) + 7x + 5
        - (2x^(3) + 2x^(2))
        ---------------------

Step 4: Subtract the product from the dividend and bring down the next term.

        2x^(2)  _______________
x + 1  |  2x^(3) + 4x^(2) + 7x + 5
        - (2x^(3) + 2x^(2))
        ---------------------
                2x^(2) + 7x + 5

Step 5: Repeat the process until the degree of the remainder is less than the degree of the divisor.

        2x^(2) + 2x + 5  _______________
x + 1  |  2x^(3) + 4x^(2) + 7x + 5
        - (2x^(3) + 2x^(2))
        ---------------------
                2x^(2) + 7x + 5
        - (2x^(2) + 2x)
        ---------------------
                   5x + 5
        - (5x + 5)
        ---------------------

The events in terms of whether they are complimentary or not are:

The probability that it will not rain tomorrow is 2 / 3.

In probability theory, complementary events are two events that together cover all possible outcomes, meaning that if one event occurs, the other cannot occur. For example, in part (a) of the question, the events of getting an even number and getting an odd number when rolling a die are mutually exclusive, meaning that they cannot happen at the same time.

In part (b), the events of getting a prime number and getting an even number when rolling a die are not complementary events because the number 2 is both prime and even.

In parts (c) through (g), the events listed are complementary events. For example, in part (c), the events of all students attending class and no students attending class cover all possible outcomes, and only one of them can happen at a time.

If the probability of rain tomorrow is 1/3, the probability of no rain tomorrow is:

The length of the dog run is 18.5 feet and the width is 14 feet. Micah can use his 65 feet of fencing to make a dog run with these dimensions.

To find the length of the dog run, we need to solve the equation for L. Here are the steps:

1. Start with the given equation: 2L + 2(L - 4.5) = 65
2. Distribute the 2 on the right side of the equation: 2L + 2L - 9 = 65
3. Combine like terms: 4L - 9 = 65
4. Add 9 to both sides of the equation: 4L = 74
5. Divide both sides of the equation by 4: L = 18.5

So, the length of the dog run is 18.5 feet. Since the length is 4.5 feet more than the width, we can find the width by subtracting 4.5 from the length:

W = L - 4.5
W = 18.5 - 4.5
W = 14

Therefore, the width of the dog run is 14 feet.

In conclusion, the length of the dog run is 18.5 feet and the width is 14 feet. Micah can use his 65 feet of fencing to make a dog run with these dimensions.

| -3 0 -6 |   | x |   | 11 |
|  5 -2  3 | * | y | = | 17 |
|  2 -1 -7 |   | z |   | -3 |
```

Where A is the coefficient matrix, x is the column matrix of variables, and b is the column matrix of constants.

To find the inverse of matrix A, we perform row operations on the augmented matrix [A|I]:

```
| -3 0 -6 | 1 0 0 |
|  5 -2  3 | 0 1 0 |
|  2 -1 -7 | 0 0 1 |

First, we divide the first row by -3:

```
| 1 0 2 | -1/3 0 0 |
| 5 -2 3 |  0   1 0 |
| 2 -1 7 |  0   0 1 |
```

Then, we subtract 5 times the first row from the second row, and 2 times the first row from the third row:

```
| 1 0  2  | -1/3  0  0 |
| 0 -2 -7 |  5/3  1  0 |
| 0 -1 -3 |  2/3  0  1 |

| 0 1 7/2 | -5/6 -1/2 0 |
| 0 -1 -3 |  2/3  0   1 |

And then we add the second row to the third row:

```
| 1 0  2  | -1/3  0   0 |
| 0 1 7/2 | -5/6 -1/2 0 |
| 0 0  1/2|  1/6 -1/2 1 |
```

Finally, we divide the third row by 1/2, and subtract 2 times the third row from the first row, and 7/2 times the third row from the second row:

```
| 1 0 0 |  0   1  -2 |
| 0 1 0 | -4/3 2  -7/2|

```

So, the inverse of matrix A is:

```
|  0   1  -2 |

Now, we can perform matrix multiplication A^-1b to get the values of the variables:

Next, we can compute the mean and standard deviation of the binomial distribution for a sample size of 210 and probability of success of 0.24:

Mean = np = 210 * 0.24 = 50.4

Standard Deviation = √(np(1-p)) = √(50.4 * (1-0.24)) = √(38.304) = 6.19

To set up the equation and solve for the 2 consecutive odd integers whose product is 195, we can follow these steps:

1. Let x be the first odd integer. 2.The next consecutive odd integer will be x+2. 3.The product of these two integers is 195, so we can set up the equation: x(x+2) = 195 4.Expand the equation: x^2 + 2x = 195

5.Rearrange the equation to get a quadratic equation: x^2 + 2x - 195 = 0 6. Use the quadratic formula to solve for x: x = (-2 ± √(2^2 - 4(1)(-195)))/(2(1)) 7. Simplify the equation: x = (-2 ± √784)/2 8. Solve for the two possible values of x: x = (-2 + 28)/2 or x = (-2 - 28)/2 9. Simplify the equations: x = 13 or x = -15 10. Since x is an odd integer, we can reject the solution x = -15. 11. The first odd integer is x = 13, and the next consecutive odd integer is x+2 = 15.

12. Therefore, the two consecutive odd integers whose product is 195 are 13 and 15.

The final answer is 13 and 15.

The factored form of the given polynomial is [tex]10a^{(2)}(6ab)^{(2)}+1-5a^{(2)}b^{(2))}[/tex]

To factor the given polynomial completely, we need to find the greatest common factor (GCF) of all the terms. The GCF of 60a^(3)b^(2), 10a^(2), and -50a^(4)b^(2) is 10a^(2).

So, we can factor out 10a^(2) from each term to get:

[tex]10a^{(2)}(6ab)^{(2)}+1-5a^{(2)}b^{(2))}[/tex]

Now, we can check our answer by multiplying the factors back together:

[tex]10a^{(2)}(6ab^{(2)}+1-5a^{(2)}b^{(2))}=60a^{(3)}b^{(2)}+10a^{(2)}-50a^{(4)}b^{(2)}[/tex]

Therefore, the factored form of the given polynomial is [tex]10a^{(2)}(6ab)^{(2)}+1-5a^{(2)}b^{(2))}.[/tex]
