To analyze the investment decision between Machine A and Machine B, various financial metrics are calculated. The payback period, accounting rate of return, net present value, and internal rate of return are determined. Based on these calculations, the suitable machine is chosen, considering the payback period, cost of capital, and other factors.

The payback period of both machines is calculated by determining the time required to recover the initial investment. It is expressed in years, months, and days. The machine with the shorter payback period indicates a faster return on investment.
Using the payback period as the sole criterion for decision-making, the machine with the shorter payback period should be chosen. However, it's important to note that the payback period does not consider the time value of money or the profitability beyond the payback period.
The accounting rate of return on average investment for Machine A is calculated by dividing the average annual profit by the average investment cost, expressed to two decimal places. This metric provides an indication of the profitability of the investment.
The net present value (NPV) of each machine is calculated by discounting the expected cash flows using the company's cost of capital (12%). NPV represents the present value of the expected cash inflows and outflows associated with the investment. The machine with the higher NPV indicates a higher value addition to the company.
The internal rate of return (IRR) of Machine B is determined using interpolation. IRR is the discount rate that equates the present value of expected cash flows to the initial investment. It indicates the profitability and return on investment of Machine B.
Considering all these factors and the company's cost of capital, a comprehensive evaluation can be made to determine the most suitable machine for investment.

A histogram is a univariate display of quantitative data that organizes data into bins and shows the frequency of observations within each bin.


A histogram is a graphical representation that displays the distribution of quantitative data. It consists of a series of contiguous bars, where each bar represents a specific range or bin of values, and the height of the bar corresponds to the frequency or count of observations falling within that range.

Histograms are commonly used to visualize the shape, central tendency, and spread of a dataset. By examining the heights of the bars, one can determine the frequency of values within each bin and identify patterns such as peaks or clusters. This makes histograms an effective tool for exploring the distribution and characteristics of a single variable in a dataset.

OMG yessss

Step-by-step explanation:

The estimated absolute error in approximating e^(-0.61) using the 4th-order Taylor polynomial of f(x) = e^x centered at 0 is approximately 1.29663 * 10^(-6).

To estimate the absolute error in approximating the quantity e^(-0.61) using the 4th-order Taylor polynomial of f(x) = e^x centered at 0, we can use the remainder term of the Taylor polynomial, also known as the Lagrange remainder or the Taylor remainder.

The remainder term for the nth-order Taylor polynomial of a function f(x) centered at a is given by:

R_n(x) = (f^(n+1)(c) / (n+1)!) * (x-a)^(n+1),

where f^(n+1)(c) is the (n+1)th derivative of f(x) evaluated at some value c between x and a.

In this case, we have f(x) = e^x, a = 0, x = -0.61, and n = 4. We need to find the (n+1)th derivative of f(x) and evaluate it at some value c between 0 and -0.61.

Let's calculate the derivatives of f(x) up to the 5th derivative:

f(x) = e^x

f'(x) = e^x

f''(x) = e^x

f'''(x) = e^x

f''''(x) = e^x

Since all derivatives of f(x) are equal to e^x, we can evaluate them at c = 0:

f^(n+1)(c) = f^(4+1)(0) = e^0 = 1.

Now we can plug these values into the remainder term formula:

R_4(-0.61) = (1 / (4+1)!) * (-0.61 - 0)^(4+1)

= (1 / 120) * (-0.61)^5

≈ 1.29663 * 10^(-6).

Therefore, the estimated absolute error in approximating e^(-0.61) using the 4th-order Taylor polynomial of f(x) = e^x centered at 0 is approximately 1.29663 * 10^(-6).

Answer:

90° and 90°.

Step-by-step explanation:

The only combination of 2 angles that sum to 180° with each not being less than 90° is 2 90° themselves! Technically, 90 is indeed not less than 90. It is not possible to find any other combinations because if one angle is made bigger, the other will be forced to become smaller, and if any angle becomes any smaller it will, of course, be less than 90° and thus not a solution to the problem.

Based on this analysis, it appears that option (d) is the correct answer as none of the other options account for the real solutions of the given quadratic equation.

To solve the equation 10820(x²- x) = 1, we can rearrange it to the quadratic form and solve for x:

10820(x² - x) = 1

Divide both sides by 10820 to isolate the quadratic term:

x² - x = 1/10820.

Multiply both sides by 10820 to clear the fraction:

10820x² - 10820x = 1.

Now we have a quadratic equation in the standard form: ax² + bx + c = 0, where a = 10820, b = -10820, and c = 1.

To solve this quadratic equation, we can use the quadratic formula:

x = (-b ± √(b² - 4ac)) / (2a).

Plugging in the values, we have:

x = (-(-10820) ± √((-10820)² - 4 * 10820 * 1)) / (2 * 10820)

x = (10820 ± √(116964400 - 43280)) / 21640

x = (10820 ± √116921120) / 21640.

Now, let's simplify the expression under the square root:

x = (10820 ± √(10820²)) / 21640

x = (10820 ± 10820) / 21640.

Simplifying further, we have:

x = 21640 / 21640 = 1 (for the plus sign)

x = 0 / 21640 = 0 (for the minus sign).

Therefore, the equation has two real solutions: x = 1 and x = 0

Answer:

In this system of equations, x is equal to one, and y is equal to three.

Step-by-step explanation:

We can solve this by rearranging either equation to define either x or y, and plugging that into the other.  As it happens, the first equation is conveniently arranged to define x, so let's use that:

3y + x = 10

3y + (2y - 5) = 10

5y - 5 = 10

y - 1 = 2

y = 3

Now that we know the value of y, we can plug it in to either of the original equations to find x:

x = 2y - 5

x = 2(3) - 5

x = 6 - 5

x = 1

Now we can check that our answer is correct by plugging that x value into either of the original equations:

3y + x = 10

3y + 1 = 10

3y = 9

y = 3

And because that gives us our original y value, we know that our answer is correct.

Using proportions, it is found that they spent a total of £5.6 for these cartons of apple juice.

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

In this problem, the daily fraction of a carton they drink is given by:

\(\frac{1}{3} + \frac{2}{5} = \frac{5 + 6}{15} = \frac{11}{15}\)

Hence, applying the proportion, over 10 days, the amount of cartons they drink is given by:

\(10 \times \frac{11}{15} = \frac{110}{15} = 7.33\)

Rounding up, they buy 8 cartons, each at £0.7. Hence the total amount spent is given by:

8 x £0.7 = £5.6.

The fraction over and multiply:

Simplify

X = (10x6)/5

X = 60/5

X = 12

The answer is x = 12

Answer:

\(\boxed {x = 12}\)

Step-by-step explanation:

Solve for the value of \(x\):

\(\frac{5}{6}x + 7 = 17\)

-Subtract both sides by \(7\):

\(\frac{5}{6}x + 7 - 7 = 17 - 7\)

\(\frac{5}{6}x = 10\)

-Multiply both sides by \(\frac{6}{5}\), which is the reciprocal of \(\frac{5}{6}\):

\(x = 10 \times (\frac{6}{5})\)

\(x = \frac{10 \times 6}{5}\)

\(x = \frac{60}{5}\)

-Divide \(60\) by \(5\):

\(x = \frac{60}{5}\)

\(\boxed {x = 12}\)

Therefore, the value of \(x\) is \(12\).
