Explanation:

1. An annuity is a number of equivalent payments made. For instance, the annuities include daily savings account deposits, monthly home loan payments, monthly insurance and pension payments. Annuity can be defined by the payment dates frequency.

Difference between an ordinary annuity and an annuity due:

In each period certain annuities shall pay the same amount, while varying annuities that differ in amounts. At the end of each time, payments in the standard annuity take place. In comparison, payments for an annuity due are made at the start of the contract.

2. The number of y-axis and discount rate on the x-axis is usually present in an annuity table. Place them on the table for your annuity and then place the cell in which they meet. Multiply the cell number by the amount of money each time is earned.

3. The annuity table contains the amount of contributions you expect to collect at a given interest rate plus a list of equivalent payments. You come to the current value of the payments when you subtract this element by one of the payments. As a quick guide the preceding annuity table includes only figures for discrete intervals and interest rates, which may be not quite the same as a real world scenario.

Answer:

b) The economy is actually harmed as there is a sharp decease in consumer spending.

Explanation:

As a result of the news of a recession people will react by planning for a future that may be bleek financially.

Savings will increase, the greater the fear of recession the more people will save to cushion the impact of recession. There is the possibility of job slow down in economic activities and resultant job losses so extra cash that would have normally been spent will be saved for the rainy day

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.

f the price of a slice of pizza rises from $2.50 to $3, and quantity demanded falls from 10,000 slices to 7,400 slices, calculat

Schach [20]

Answer:

arc price elasticity = -1.64

Explanation:

arc price elasticity = (change in quantity x average price) / (change in price x average quantity)

change in quantity = 7,400 - 10,000 = -2,600 units
average price = ($2.50 + $3) / 2 = $2.75
change in price = $3 - $2.50 = $0.50
average quantity = (10,000 + 7,400) / 2 = 8,700 units

arc price elasticity = (-2,600 x $2.75) / ($0.50 x 8,700) = -7,150 / 4,350 = -1.64

Explain the difference between the law of diminishing marginal returns and the law of dininishing marginal rate of techinal subs

leonid [27]

Answer:

The primary difference between those two concepts is focus that each term has. The first one focus on the relationship between the level of production and the level of return. While the second one focus on the relationship between the level of production and the amount of factors used for that production.

Explanation:

One the one hand, the law of diminishing marginal returns is a concept known in the microeconomics theory due to the fact that it establishes the relationship between the productivity and the income for every aspect of it. Meaning that, when the productivity increases because of the increase of only one factor of production then the income will start to slowly decrease, confirming that when only one factor is increased the production will start to be incomplete and the return will decrease for that.

On the other hand, the law of diminishing marginal rate of technical substitution indicates the relationship between the level of output and the different factor used to produce. Meaning that, it shows how to keep the level of output the same while making changes in the amount of factors used.
