Answer: $0.79

Given:

C=Cost of the land: $1,981,300

S=Salvage value of the land: $267,000

N=Total number of ores mined= 2,170,000 tons

To get the depletion expense per ton of ore:

(C-S)/N

=($1,981,300-$267,000)/2,170,000

=1,714,300/2,170,000

=$0.79

Explain how a Target price for farm crops is an example of a price floor.​
12345 [234]

Answer: A target price for farm crops is an example of price floor because it’s fixed ahead of harvests with the interest of farmers in mind.

Explanation: A quick definition of both concepts would be of help. A price floor is usually fixed by government legislation and it ensures that the price of a commodity or service does not fall below a certain minimum. In the case of farm crops, a floor price makes sure that the farmers are guaranteed a level of profit in case there is poor harvest for any reason whatsoever. The price floor must be fixed above the equilibrium price for this to be effective.

A target price is an expectation of the future price of commodities or services, and hence prices are fixed ahead of the harvest in the case of farm crops. This is so because as explained earlier, future conditions might change and become unfavorable, therefore making the current market price unprofitable for farmers. If for example, a sack of potatoes currently sells for $30, the government may fix the price floor ahead of the harvest season at $45 per sack. This implies that after harvesting farmers can still sell at $30. However if the harvest turns out to be bad perhaps due to natural disasters, pests or fungal attacks, etc, then the farmers can go ahead and sell at $45 and possibly higher. No farmer is allowed to sell below $45 (since that is the ‘floor’). That way, farmers would still have some profit guaranteed and would be encouraged to remain in the farming business.

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.
