Answer:
[ -0.13, -0.15 ] ( D )
Explanation:
Given data :
sample size ( n ) = 50
Independent variable ( p ) = 1
<u>determine the confidence interval for the slope </u>
Df ( degree of freedom ) = n - p - 1 = ( 50 - 1 - 1 ) = 48
b ( estimated slope ) = -0.23
Standard error of slope = 0.04
confidence interval = 95%
For confidence interval of 95% and Df of 48 ; critical value ( t ) = 2.011
∴ Confidence interval
= -0.23 ± ( 2.011 * 0.04)
= -0.23 ± 0.08044
= [ -0.13, -0.15 ]
Answer:
$2,800
Explanation:
An interest only loan represents a type of loan offer where a borrower is only expected to pay the interest either for some of the term of the loan as agreed or for all of the terms of the loan. However, the principal amount that is collected remains constant all through the agreed interest -only period.
Since the loan obtained by John's Auto Repair is Interest Only, it means that the principal of $35,000 remains constant.
Hence, in the 8th year, John is expected to pay only the interest for the period =
0.08 x $35,000
= $2,800

3) laissez-faire
Explanation:
Laissez-faire is a French expression that means to let us do, or applied to economics, let the economy self regulate itself. It was not a doctrine developed by Adam Smith, but rather by French economists who supported the idea of no government intervention in the economy.
President Coolidge believed that the government should not interfere with businesses and that businesses themselves were able to create prosperity for the nation.
Answer:
PV= $620,921.32
Explanation:
Giving the following information:
Cash flow (Cf)= $100,000
Interest rate (i)= 7.25%
<u>First, we need to calculate the value of the investment at the moment of the first payment (five years from now). </u>To calculate the present value we need to use the following formula:
PV= Cf / i
PV= 100,000 / 0.1
PV= $1,000,000
<u>Now, the value today:</u>
PV= FV / (1 + i)^n
PV= 1,000,000 / (1.1^5)
PV= $620,921.32
This change is an example of the <u>"Ergonomic"</u> approach to job design.
"Job design" alludes to the way that an arrangement of assignments, or a whole job, is composed. Job design decides:
What tasks are finished.
How the tasks are finished.
What number of tasks are finished.
In what arrange the tasks are finished.
A well designed job will energize an assortment of 'good' body positions, have sensible quality necessities, require a sensible measure of mental movement, and help cultivate sentiments of accomplishment and confidence.
Ergonomics is the art of coordinating the job to the laborer and the item to the client.
