Answer:

c. Increase by $0.1 trillion

Explanation:

Investment spending Multiplier is a concept in economics that measure how a given change in investment increases output. So if current output of $13.5 trillion must increase to $14 trillion, we employ the multiplier formula to derive what amount of investment spending is needed to get $o.5trillion increase in output.

(change in output)/ (change in investment) = 1/(1-mpc)

Note that mpc means marginal propensity to consume.

Let change in investment = X

change in output = 14 - 13.5 = $0.5trillion

mpc = 0.8

(0.5)/X = 1(1-0,8)

0.5/X = 1/0.2

cross multiply

X = 0.1

Thus the needed change in investment is an increase of $0.1 trillion. In other words, if investment increases by $0.1 trillion, current output will increase from $13.5 trillion to $14 trillion.

nexus9112 [7]

Answer:

A= $4,838.95 monthly

Explanation:

Giving the following information:

She is currently planning to retire in 30 years and wishes to withdraw $10,000/month for 20 years from her retirement account starting at that time.

First, we need to calculate the amount needed for retirement:

FV= 10,000*12*20= 2,400,000

Now, we can use the following formula:

FV= {A*[(1+i)^n-1]}/i

A= annual deposit

Isolating A:

A= (FV*i)/{[(1+i)^n]-1}

Effective rate= 0.02/12= 0.0017

n= 12*30= 360

A= (2,400,000*0.0017)/[(1.0017^360)-1]

A= $4,838.95 monthly

White raven [17]

Answer:

a) The correlation coeffcient is given by:

r = \frac{Cov(X,Y)}{S_x S_y}

And replacing we got:

r = \frac{-36.111}{4.638 *9.084}= -0.857

b) For this case we can conclude that we have a strong, negative linear association between the two stock prices.

Explanation:

Part a

For this case we have the following info:

s_x = 4.638 represent the sample deviation for the variable X

s_y = 9.084 represent the sample deviation for the variable Y

Cov(X,Y)= -36.111 represent the covariance between the variables X and Y

The correlation coeffcient is given by:

r = \frac{Cov(X,Y)}{S_x S_y}

And replacing we got:

r = \frac{-36.111}{4.638 *9.084}= -0.857

Part b

Describe the relationship between prices of these two stocks.

For this case we can conclude that we have a strong, negative linear association between the two stock prices.
