The gross pay for the given service is $343.2.

Gross pay is what employees earn before taxes, benefits and other payroll deductions are withheld from their wages.

Given that, the regular salary of some service is $7.80 per hour, we need to calculate the gross payment with over time hour, which is 4 hours and regular hour of work is 40 hours.

Therefore,

To find, gross payment, we will multiply by 7.80 by 4 and 40, and add both to get the regular salary,

Gross payment = 7.80 × 4 + 7.80 × 40  

= 7.80(4+40)

= 7.80 × 44

= 343.2

Answer:12x³ - 36x² + x^5 = (6x²)(2x - 4) + x^5.

Step-by-step explanation:To divide the polynomial 12x³ - 36x² + x^5 by 6x², we can use polynomial long division. Here's the process:

Divide the first term of the dividend (12x³) by the first term of the divisor (6x²). The result is 2x.

Multiply the divisor (6x²) by the quotient (2x) to get 12x³.

Subtract the product from the dividend (12x³ - 36x² + x^5). The result is -24x² + x^5.

Repeat the process for the next term of the dividend, which is -24x². Divide it by the divisor (6x²) and get -4 as the quotient.

Multiply the divisor (6x²) by the quotient (-4) to get -24x².

Subtract the product from the remaining dividend (-24x² + x^5). The result is x^5.

The remainder is x^5, which means that 6x² is a factor of 12x³ - 36x² + x^5, but x^5 is not a factor of 6x².

Therefore, the final answer is:

12x³ - 36x² + x^5 = (6x²)(2x - 4) + x^5.

The minimal value of n for which there is at least a 0.90 probability of the system functioning is 4, which is the smallest conceivable value.

The likelihood of a 3 out of 5 system working was calculated to be 0.9914.

Think about the 3 out of 4 system.

A minimum probability of 0.90 must exist for 3 out of 4 systems to function.

Calculate the likelihood that a 3 out of 4 system will function as follows:

[tex]P (X ≥ 3) = 1 - P (X < 3) = 1 - P (X = 0) - P (X = 1) - P (X = 2)[/tex]

A three out of four system having a good chance of working is 0.9477.

Take a look at a 3 out of 3 system.

See if the likelihood of a 3 out of 3 system operating is at least 0.90.

Calculate the likelihood that a 3 out of 3 system will function as follows:

[tex]P (X ≥ 3) = 1 - P (X < 3) = 1 - P (X = 0) - P (X = 1) - P (X = 2)[/tex]

A three-out-of-three system's likelihood of success is 0.7290.

Since the likelihood of the system functioning is at least 0.90 for a number of n as little as 4, that value is the smallest feasible.

Answer:

The distance around the edge of a circular pool is equal to its circumference. If the circumference is 24 meters, then we can use the formula for circumference of a circle, C = 2πr, to find the radius, r.

C = 2πr

24 = 2πr

12 = πr

r = 12/π

The distance from the edge of the pool to the center is equal to the radius of the pool. So, the distance from the edge of the pool to the center is:

r = 12/π = 12/3.14 = 3.83 meters (rounded to 1 decimal place)

$20,000 due in 50 years would be worth approximately $6,307.51 today, if the discount rate were 7.5%.

The present value of $20,000 due in 50 years, discounted at 7.5%, can be calculated using the formula:

PV = FV / (1 + r)^t

Where:

PV = present value

FV = future value ($20,000)

r = discount rate (7.5%)

t = number of years (50)

Plugging in the numbers, we get:

PV = $20,000 / (1 + 0.075)^50

PV = $20,000 / (1.075)^50

The entries in the matrix correspond to whether or not the two elements in the set are related or not related according to the complement of the original relation.

To find the matrix for the complement of a relation, r, given the matrix representing r on a finite set a, you first need to determine the size of the matrix, which is equal to the number of elements in the set. The matrix for the complement of r is simply the matrix for r with all of its entries negated. In other words, you switch all of the 1's to 0's and all of the 0's to 1's.

For example, if the matrix for r is:

[tex]\left[\begin{array}{ccc}1&0&1\\0&1&0\\1&0&1\end{array}\right][/tex]

The matrix for the complement of r would be:

[tex]\left[\begin{array}{ccc}0&1&0\\1&0&1\\0&1&0\end{array}\right][/tex]

The solution is, the Bank of Peace will pay Marco more in interest over the 3-year period, Marco should choose the Bank of Peace to get the most interest, the total amount of interest that Marco will earn from the Bank of Trust over the 3-year period is, = £870.

Interest is the price you pay to borrow money or the cost you charge to lend money. Interest is most often reflected as an annual percentage of the amount of a loan. This percentage is known as the interest rate on the loan.

here, we have,

To determine which bank will give Marco the most interest over the 3-year period, we need to calculate the total amount of interest that each bank will pay Marco over the 3 years.

First, let's consider the Bank of Peace.

Since the interest rate is 2.5% per year and is compounded annually, Marco will earn 2.5/100 * £15000 = £375 in interest in the first year. In the second year, the interest will be calculated on the original £15000 plus the £375 of interest earned in the first year, for a total of £15000 + £375 = £15375.

So Marco will earn 2.5/100 * £15375 = £383.44 in interest in the second year. In the third year, the interest will be calculated on the original £15000 plus the £375 of interest earned in the first year and the £383.44 of interest earned in the second year, for a total of

£15000 + £375 + £383.44 = £15728.44.

So Marco will earn 2.5/100 * £15728.44 = £391.71 in interest in the third year.

Therefore, the total amount of interest that Marco will earn from the Bank of Peace over the 3-year period is £375 + £383.44 + £391.71 = £1150.15.

Now let's consider the Bank of Trust. In the first year, Marco will earn 3.8/100 * £15000 = £570 in interest.

In the second year, the interest rate is 1%, so Marco will earn 1/100 * £15000 = £150 in interest. In the third year, Marco will also earn £150 in interest.

Therefore, the total amount of interest that Marco will earn from the Bank of Trust over the 3-year period is £570 + £150 + £150 = £870.

Since <1 and <2 are vertical angles, they are equal, so m<2 = 8x - 15 = 8(6) - 15 = 39°  , Since <2 is supplementary to <3,  m<3 = 180° - 39° m<3 = 141°

Vertical angles are angles that are opposite each other when two lines cross. They always have the same measure and are supplementary angles (add up to 180°). Vertical angles are also known as opposite angles or vertically opposite angles. When two lines intersect, four angles are formed. The two pairs of angles opposite each other are known as vertical angles. This is because the lines that they share are vertical to each other, which is why they are also known as vertically opposite angles. Vertical angles can be found in a variety of shapes and figures, including parallelograms, triangles, and quadrilaterals. They can be used to solve many mathematical problems and are an important concept to learn in geometry.

4x + 9 = 8x - 15

4x - 8x = -15 - 9

-4x = -24

x = 6

Therefore, m<2 = 8x - 15 = 8(6) - 15 = 39°

Since <2 is supplementary to <3,

m<3 = 180° - 39°

Step-by-step explanation:

A correlation coefficient of -0.9 means that there is a strong negative linear relationship between two variables, while a correlation coefficient of 0 means that there is no linear relationship between the two variables.

When two variables have a strong negative linear connection, the values of one variable grow while the values of the other variable fall, and vice versa. When there is no linear relationship, the values of the two variables are more densely packed around the line of best fit, resulting in a smaller standard deviation.

When there is no linear relationship between two variables, the values of the variables are randomly distributed, and there is no consistent link between them. The standard deviation is bigger in this case because the values of the two variables are more spaced apart.
