The method of pay that would result in the most earnings for one month on sales of $60,000 would be: d. Graduated commission of 5% on the first $40,000 in sales and 9% on anything over that.

The earnings can be calculated as follows:

a. Earnings =   6% of 60000  

Earnings = $3,600

b. Earnings = 1500 + .03(60000)

Earnings = 1500 + 1800

Earnings = $3,300

c. For the first $50,000: $50,000 * 4% = $2,000

For the remaining $10,000: $10,000 * 10% = $1,000

Total earnings: $2,000 + $1,000 = $3,000

d.  For the first  5 % ×40,000 = 2000

For the remaining (60,000-40,000) = .09 x 20000 = 1800

Total earnings :2000 + 1800 = $3,800

Therefore the correct option is D.

If the highest value is increased by 10 and the lowest is decreased by 10 the mean doesn't change

Let us assume the data set with 10 observations:

{5, 6, 4, 3, 2, 6, 4, 9, 4, 4}.

Arranging data set in ascending order

{2, 3, 4, 4, 4, 4, 5, 6, 6, 9}

Mean of this data = Sum of all observations/Total number of observations

Mean = (2 + 3 + 4 + 4 + 4 + 4 + 5 + 6 + 6 + 9)/10

Mean = 47/10 = 4.7

Now, Increasing the highest value by 10 and decreasing the lowest value by 10

So, the new data set is {-8, 3, 4, 4, 4, 4, 5, 6, 6, 19}

Mean of this data = -8 + 3 + 4 + 4 + 4 + 4 + 5 + 6 + 6 + 19/10

Mean = 47/10 = 4.7

Hence, the mean doesn't change.

The difficulty of range as a measure of variability that is overcome by interquartile range is option b that is The range is influenced too much by extreme values.

The variance is the mean squared difference between each data point and the mean-centered distribution. A statistical assessment of the dispersion of values in a data collection is referred to as variance. Variance explicitly assesses how distant each number in the set is from the mean (average), and consequently from every other number in the set. Variance is a measure of how data points differ from the mean, whereas standard deviation is a measure of statistical data distribution. The primary distinction between the two is that standard deviation is expressed in the same units as the mean of the data, whereas variance is expressed in squared units.

The measurement of the side g in the Δ EFG is 218.38

The law of sine or the sine law states that the ratio of the side length of a triangle to the sine of the opposite angle, which is the same for all three sides.

Given that, In Δ EFG, f = 400 inches, m ∠ F = 94° and m ∠ G = 33°, we need to find, the length of g (refer to figure attached)

Using the sine rule of the triangle,

f / Sin F = g / Sin G = e / Sin E

400 / Sin 94° = g / Sin 33°

g = 400 / Sin 94° × Sin 33°

There are many more people awaiting such a transplant than there are available organs, leading to a large backlog of patients who are not able to receive an organ transplant.

In 2008, the United States Department of Health and Human Services reported that there were approximately 113,000 patients in the United States awaiting organ transplants. Of those, only 28,535 received an organ transplant that year. This is a ratio of approximately 1 in 4. This can be expressed mathematically as 28,535/113,000 = 0.25, or one fourth. This means that for every 4 people awaiting an organ transplant in the United States in 2008, only 1 actually received one.

Answer:

The fifth salary = $49,000

Step-by-step explanation:

Let x be the fifth salary

Total salary = $36,000, +  $45,000 + $28,000 + $32,000 + x

= $141,000 + x

The average of 5 salaries is $38,000

Total = Average x number of elements

= 38000 x 5 = 190,000

Equating the two totals

141,000 + x = 190,000

Subtract 141, 000 from both sides

x = 190,000 - 141, 000

x = $49,000

So the fifth salary = $49,000

If each of the plant's cans was filled to 12 ounces, the standard deviation of the sample of 10 cans would give us an idea of how much the weights of the cans deviate from the average weight of 12 ounces.

The calculation of the standard deviation requires knowledge of the mean and variance of the sample. To find the variance, we would need to subtract the mean from each of the observed weights, square the differences, and find the average of the squared differences. Finally, to find the standard deviation, we would take the square root of the variance.

It's worth noting that in practice, finding the standard deviation of a sample can be a complex and time-consuming process, especially when dealing with large sample sizes. However, it is a valuable metric that provides important information about the distribution and spread of the data.

P(J|W)

Let's assume that we have some knowledge of such two numbers. I believe

In addition, we recognize how likely it is that she will receive either one or both letters: P(J|S)=0.8 P(J|W)=0.1

Note that P(S)+P(W)=1 since there are only two possibilities: P(S)=0.7 and P(W)=0.3.

This is a representation of two distinct directions that could be taken. In one, we receive a compelling letter and ponder if she'll be hired in light of that compelling letter. As a result of the weak letter from the other, we are unsure if she will be hired.

When describing bell-shaped distributions statistically, the standard deviation is utilised along with the mean.

What does the mean actually measure?

While the standard deviation gauges the distribution's spread, the mean gauges the distribution's centre.

What is the purpose of standard deviation?

For the aim of quantifying dispersion, or the variation that takes place in the values of a data set that is taken into consideration, the standard deviation is used. The data points are said to be close to the mean when the standard deviation number is reduced. The opposite will occur when it is higher. In this way, it gauges how widely apart data points are from the mean.

Anything's predicted value is sometimes referred to as a mean. It is the object that serves as the focal point for all data points. The standard deviation determines how widely apart all the data points are from the mean, whereas the mean is the centre of the distribution.

What is the name of standard deviation?

Because it is the square root of the means of the squared errors from the arithmetic average, standard deviation is often referred to as root-mean square deviation. Standard deviation is a word used in economics to indicate how risky an investment is.
