Let x be per capita income in thousands of dollars. Let y be the number of medical doctors per 10,000 residents. Six small citie

MAVERICK [17]

Answer:

The percentage of variation esplained by the model is given by the determination coefficient, on this case:

$R^2 = 0.934^2 =0.872$

And we have 87.2% of the variation explained by the linear model given.

$\hat y = 5.756(8.5) -36.895=12.031$

And we have 12.031 doctors per 10000 residents.

Explanation:

Assuming the following dataset:

x y

8.6 9.6

9.3 18.5

10.1 20.9

8.0 10.2

8.3 11.4

8.7 13.1

Assuming this question: "The data has a correlation coefficient of r = 0.934. Calculate the regression line for this data. What percentage ofvariation is explained by the regression line? Predict the number of doctors per 10,000 residents in a town with a per capita income of $8500."

We want a linear model like this:

$y = mx +b$

Where m represent the slope and b the intercept for the linear model. And we cna find the slope and b with the following formulas:

$m = \frac{n \sum xy - \sum x \sum y}{n \sum x^2 -(\sum x)^2}$

$b = \frac{\sum y}{n} -m \frac{\sum x}{n}$

And from the dataset we have the following values:

$n= 6, \sum x =53, \sum y = 83.7 , \sum xy = 755.89, \sum x^2 = 471.04$

And replacing into the equation for m we got:

$m =\frac{6(755.89) - (53)(83.7)}{6(471.04) -(53)^2}=5.756$

And the intercept:

$b = \frac{83.7}{6}-36.895 5.756 \frac{53}{6}=-36.895$

And then the linear model is given by:

$\hat y = 5.756 x -36.895$

We can find the estimation replacing x = 8.5 into the linear model and we got:

$\hat y = 5.756(8.5) -36.895=12.031$

And we have 12.031 doctors per 10000 residents.

The percentage of variation esplained by the model is given by the determination coefficient, on this case:

$R^2 = 0.934^2 =0.872$

And we have 87.2% of the variation explained by the linear model given.

Kearney, Inc., makes kitchen tools. Company management believes that a new model of coffee grinder would sell well at a price of

IRINA_888 [86]

Answer:

$0.15 hours per unit

Explanation:

Given that

Direct material cost = $16

Assume Direct labor cost = X

Manufacturing overheads = $18

Profit margin = 20%

Direct labor per hour cost = $28

The computation of direct labor-hour input is shown below:-

Total manufacturing cost = X + $34

Total cost of goods sold = (X + $34) × 1.7 = $66

Direct labor cost per unit

= (X + $34) = $38.82

= $38.82 - $34

= $4.32

Direct labor hours per unit = Direct labor cost per unit ÷ Direct labor per hour cost

= $4.32 ÷ $28

= $0.15 hours per unit

Answer:

Vanishing Games Corporation (VGC)

1. Analysis of the effect of transactions on the accounting equation:

Assets = Liabilities + Equity

Assets (Cash) increases +$52,500 and Assets (Accounts Receivable) decreases -$52,500 = Liabilities + Equity.

b. Assets (Cash) increases +$235,000 = Liabilities + Equity (Retained Earnings) increase + $235,000.

c. Assets (Equipment) increases +41,900; Cash decreases -$12,000 = Liabilities (Notes Payable) increase +$29,900 + Equity.

d. Assets (Cash) decreases -$15,600 = Liabilities + Equity (Retained Earnings) decrease - $15,600.

e. Assets (Cash) increases + $50,500 and (Accounts Receivable) increases + $50,500 = Liabilities + Equity (Retained Earnings) increase + $101,000.

f. Assets = Liabilities (Accounts Payable) increase +$5,900 + Equity (Retained Earnings) decrease -$5,900.

g. Assets (Cash) decreases - $310,000 = Liabilities + Equity (Retained Earnings) decreases - $310,000.

h. Assets (Supplies) increase + $5,100 = Liabilities (Accounts Payable) increase +$5,100 + Equity.

i. Assets (Cash) decreases - $5,100 = Liabilities (Accounts Payable) decrease - $5,100 + Equity.

Steven lives in a big city where there is a shortage of parking. He has a parking spot in his driveway where he parks his car. W

DENIUS [597]

Answer:

The correct answer is option C.

Explanation:

The opportunity cost of any economic decision is the cost of giving up its alternative. We are aware that we have limited resources with alternative uses and we have to use these resources to satisfy alternative needs and wants. In order to increase spending resources on one thing, we need to decrease spending on its alternative.

Here, the parking spot on the driveway can be used for personal use or can be used for renting. The opportunity cost of using the spot for personal parking is the money that could have been earned by renting it to others.
