Answer:

  $98.11

Step-by-step explanation:

If your calculator doesn't work with mixed numbers, you must first convert 6 5/8% to a decimal fraction.

  6 5/8 = (6·8+5)/8 = 53/8 = 6.625

  6 5/8% = 0.01×6.625 = 0.06625

Then the desired amount is ...

  0.06625 × $1480.90 = $98.109625 ≈ $98.11

6 5/8% of $1,480.90 is $98.11.

The Operating income is $172,500.

To calculate the margin of safety, contribution margin ratio, and operating income, we need to use the given information.

a. Margin of Safety:

Margin of Safety = Actual Sales - Break-even Sales

Given that the break-even point is at $750,000 in sales revenue and actual sales are $1,100,000, we can calculate the margin of safety:

Margin of Safety = $1,100,000 - $750,000 = $350,000

Therefore, the margin of safety is $350,000.

b. Margin of Safety as a Percentage of Sales:

Margin of Safety Percentage = (Margin of Safety / Actual Sales) * 100

Using the values from the previous calculations:

Margin of Safety Percentage = ($350,000 / $1,100,000) * 100 = 31.82%

Therefore, the margin of safety expressed as a percentage of sales is approximately 31.82%.

c. Contribution Margin Ratio:

Contribution Margin Ratio = (Contribution Margin / Sales) * 100

To calculate the contribution margin, we need to subtract variable costs from sales:

Contribution Margin = Sales - Variable Costs = $1,100,000 - $645,000 = $455,000

Using the values, we can calculate the contribution margin ratio:

Contribution Margin Ratio = ($455,000 / $1,100,000) * 100 = 41.36%

Therefore, the contribution margin ratio is approximately 41.36%.

d. Operating Income:

Operating Income = Sales - Variable Costs - Fixed Costs

Using the values provided:

Operating Income = $1,100,000 - $645,000 - $282,500 = $172,500

Therefore, the operating income is $172,500.

The confidence interval's upper and lower limits, respectively, are \(0.330\) and \(0.206\).

Similar to the upper limit, the lower threshold is indeed the smallest value in the class interval. To get the real lower limit, take the smallest number and either deduct 0.5 from it if it's a whole number or 0.05 from it if it's a decimal.

The highest and smallest values which a number may have prior to being rounded are known as upper and lower limits. These are also known as accuracy limitations.

\(CI = p +- z\sqrt{(p(1-p)/n)}\)

where

\(p =\) sample proportion \(= 67/250 = 0.268\)

\(z = z-\)score for a \(90\)% confidence level \(= 1.645\) (from standard normal distribution table or calculator)

\(n =\) sample size \(= 250\)

Substituting these values, we get:

\(CI = 0.268 +- 1.645\sqrt{(0.268(1-0.268)} /250)\)

\(= 0.268 +- 0.062\)

Therefore, the \(90\)% confidence interval for the proportion of all X-ray machines that malfunction is \((0.206, 0.330)\).

The lower limit of the confidence interval is \(0.206\), and the upper limit is \(0.330\).

This situation represents [a.) exponential decay

The rate of growth or decay, r, is equal to  c.) 0.2

So the value of the computer each year is g.) 80% of the value in the previous year.

It will take [i.) 3 years for the value of the computer to reach $512.

Step-by-step explanation:

Since the value depreciates each year, it represents exponential decay.

The rate of growth or decay, r, is equal to

Depreciates 20%, so r = 0.2.

So the value of the computer each year is ... of the value in the previous year,

Depreciates 20%, so it is 100% - 20% = 80% of the value in the previous year.

It will take x years for the value of the computer to reach $512.

The value of the computer after x years is given by:

\(V(x) = V(0)(1-r)^x\)

In which V(0) is the initial value and r is the decay rate. So

\(V(x) = 1000(1-0.2)^x\)

\(V(x) = 1000(0.8)^x\)

We want to find x for which V(x) = 512. So

\(V(x) = 1000(0.8)^x\)

\(512 = 1000(0.8)^x\)

\((0.8)^x = \frac{512}{1000}\)

\((0.8)^x = (0.512)\)

Applying log to both sides:

\(\log{(0.8)^x} = \log{(0.512)}\)

\(x\log{0.8} = \log{(0.512)}\)

\(x = \frac{\log{0.512}}{\log{0.8}}\)

\(x = 3\)

So it will take 3 years.

Therefore , the solution of the given problem of standard deviation comes out to be the group standard deviation in order to use (b) z.

Statistics uses variance as a way to quantify difference. The image of the result is used to compute the average deviation between the collected data and the mean. Contrary to many other valid measures of variability, it includes those pieces of data on their own by comparing each number to the mean. Variations may be caused by willful mistakes, irrational expectations, or shifting economic or business conditions.

Here,

We use the z-distribution if the total standard deviation is known; otherwise, we use the t-distribution.

Additionally, for small sample sizes, the t-distribution is used, whereas for big sample sizes, the z-distribution is used.

The fact that z requires that you know the population standard deviation, and that this is frequently not known in practice, is one reason to use a distribution rather than the traditional .

The x-intercepts are at (1, 0) and (1/3, 0), so we plot these Points on the x-axis. The turning point is at (2/3, -5/9), so we plot this point on the graph as well.

The given function is 7(x) = 3x^2 - 4x + 1.To find the y-intercept of the given function, we must put x = 0 in the given function. Therefore,7(0) = 3(0)^2 - 4(0) + 1 ⇒ y = 1

So, the y-intercept is (0, 1).To find the x-intercepts of the given function, we must put y = 0 in the given function. Therefore,7(x) = 3x^2 - 4x + 1 ⇒ 3x^2 - 4x + 1 = 0

Using the quadratic formula, we get:$$x = \frac{4 \pm \sqrt{{(-4)}^2 - 4 \times 3 \times 1}}{2 \times 3} = \frac{4 \pm \sqrt{16 - 12}}{6} = \frac{4 \pm 2}{6}$$x = 1 or x = 1/3.So, the x-intercepts are (1, 0) and (1/3, 0).

Now, we can calculate the turning point by using the formula :$$x = \frac{-b}{2a}$$where a and b are the coefficients of the x^2 and x terms, respectively. Here, a = 3 and b = -4.

Therefore,$$x = \frac{-(-4)}{2 \times 3} = \frac{2}{3}$$Now, to find the corresponding y-coordinate of the turning point, we can substitute x = 2/3 in the given function, so:7(x) = 3x^2 - 4x + 1⇒ 7(2/3) = 3(2/3)^2 - 4(2/3) + 1⇒ y = -5/9So, the turning point is at (2/3, -5/9).

Now, we can sketch the graph using the information we have found:

The y-intercept is at (0, 1), so we plot this point on the y-axis. The x-intercepts are at (1, 0) and (1/3, 0), so we plot these points on the x-axis. The turning point is at (2/3, -5/9), so we plot this point on the graph as well.
