Answer: elastic; inelastic
Explanation:
A good is considered (elastic) when producers can quickly supply more or less of it based on changing prices while a good is considered (inelastic) when producers can quickly change how much of it is supplied when prices change.
In an elastic good, a change in price brings about a significant shift in the demand of such good while on the other hand, in an inelastic good, a change in price brings about an insignificant shift in the demand of such good.
Answer:
n = 150.06
Explanation:
Since the confidence c = 95% = 0.95
α = 1 - 0.95 = 0.05

z score of 0.025 is the same as the z score of 0.5 - 0.025 = 0.475
From the probability table, 
Also E = 0.08
Therefore the sample size n is given by:

n = 150.06
The sample must be at least 150.06 to be 95% sure that a point estimate will be within a distance of 0.08 from p
Answer:
net income increase of 11.25%
Explanation:
If the price p is reduced a 11% means that new price will be p(1-0.11)
New price = 0.89p
The new quantities demandes will increase a 25%, this means that the new quantities will be Q*(1+.025) = 1.25Q
So, the net income under this new circunstances will be
1.25 Q * 0.89P = 1.1125 P*Q
This means a net income increase of 11.25%
Answer:
40 dolllar for interest income
Explanation:
The taxable income will be the interest for the annual coupon payment:
$1,000 face value x 4% = $40
The purchase price will be considered for taxation purpose under capital gain if the bond is sold which is not the case. Thus, we must only determinate taxes considering the interest income from the coupon payment.
Answer: Systematic
Explanation: It refers to a method of sampling in which the samples are selected from a population randomly but as per a set criteria and defined interval. The interval is computed by dividing the population with the sample size needed.
In the given case, the quality manager starts taking sample on the on a fixed interval, that is, every 19th car after the ninth car.
Hence from the above we can conclude that the correct option is B.
