The science that studies trends and changes in human populations is called demography. Thus, option C is correct.

<h3>What is the population? </h3>

The population can be defined as the number of people present in a particular region. The region can be locality, city, country, or the world.

The quantitative study of human inhabitants is called demography. Demographers examine the range, migration, and composition of people using census data, surveys, and statistical models. It also includes the death and birth and mortality ratio. Therefore, option C is the correct option.

Consumer surplus is A. the difference between the highest price a consumer is willing to pay and the price the consumer actually

ss7ja [257]

Answer is A

Explanation: Consumer surplus actually happens when a customer is willing and ready to pay for a particular product than its current market price. It is a measure of the additional benefits a consumer gets after paying for a product even though they are willing to pay more.

For example: Let's assume you want to get a IPhone 8 plus and you value it at $800 dollars, which you are ready to pay, but realise it is sold at $700. When you buy it at $700, the customer surplus is $100, that is a difference between how much you were willing to pay and the price you eventually got it.

Consumer Surplus changes as the equilibrium price of a good rises or falls. If the price of a good rises, the consumer surplus decreases but when the price of the good falls, the consumer surplus increases.

You are interested in valuing a 2-year semi-annual corporate coupon bond using spot rates but there are no liquid strips availab

Scorpion4ik [409]

Answer:

Following are the solution to this question:

Explanation:

Assume that $r_1$ will be a 12-month for the spot rate:

$\to 1.25 \% \times \frac{100}{2} \times 0.99 + \frac{(1.25\% \times \frac{100}{2}+100)}{(1+\frac{r_1}{2})^2}=98\\\\\to \frac{1.25}{100} \times \frac{100}{2} \times 0.99 + \frac{(\frac{1.25}{100} \times \frac{100}{2}+100)}{(1+\frac{r_1}{2})^2}=98\\\\\to \frac{1.25}{2} \times 0.99 + \frac{(\frac{1.25}{2} +100)}{(1+\frac{r_1}{2})^2}=98\\\\\to 0.61875 + \frac{( 0.625 +100)}{(\frac{2+r_1}{2})^2}=98\\\\\to 0.61875 + \frac{( 100.625)}{(\frac{2+r_1}{2})^2}=98\\\\\to 0.61875 + \frac{402.5}{(2+r_1)^2}=98\\\\$

$\to 0.61875 + \frac{402.5}{(2+r_1)^2}=98\\\\\to 0.61875 -98 = \frac{402.5}{(2+r_1)^2}\\\\\to -97.38125= \frac{402.5}{(2+r_1)^2}\\\\\to (2+r_1)^2= \frac{402.5}{ -97.38125}\\\\\to (2+r_1)^2= -4.13\\\\ \to r_1=3.304\%$

Assume that $r_2$ will be a 18-month for the spot rate:

$\to 1.5\% \times \frac{100}{2} \times 0.99+1.5\% \times \frac{100}{2} \times \frac{1}{(1+ \frac{3.300\%}{2})^2}+\frac{(1.5\% \times \frac{100}{2}+100)}{(1+\frac{r_2}{2})^3}=97\\\\\to \frac{1.5}{100} \times \frac{100}{2} \times 0.99+\frac{1.5}{100} \times \frac{100}{2} \times \frac{1}{(1+ \frac{\frac{3.300}{100}}{2})^2}+\frac{(\frac{1.5}{100} \times \frac{100}{2}+100)}{(1+\frac{r_2}{2})^3}=97\\\\$

$\to \frac{1.5}{2} \times 0.99+\frac{1.5}{2}\times \frac{1}{(1+ \frac{\frac{3.300}{100}}{2})^2}+\frac{(\frac{1.5}{2} +100)}{(1+\frac{r_2}{2})^3}=97\\\\\to 0.7425+0.75 \times \frac{1}{(1+ \frac{\frac{3.300}{100}}{2})^2}+\frac{(0.75 +100)}{(1+\frac{r_2}{2})^3}=97\\\\\to 1.4925 \times \frac{1}{(1+0.0165)^2}+\frac{(100.75 )}{(1+\frac{r_2}{2})^3}=97\\\\\to 1.4925 \times \frac{1}{(1.033)}+\frac{(100.75 )}{(1+\frac{r_2}{2})^3}=97\\\\$

$\to 1.4925 \times 0.96+\frac{(100.75 )}{(1+\frac{r_2}{2})^3}=97\\\\\to 1.4328+\frac{(100.75 )}{(1+\frac{r_2}{2})^3}=97\\\\\to 1.4328-97= \frac{(100.75 )}{(1+\frac{r_2}{2})^3}\\\\\to -95.5672= \frac{(100.75 )}{(1+\frac{r_2}{2})^3}\\\\\to (1+\frac{r_2}{2})^3= -1.054\\\\\to r_2=3.577\%$

Assume that $r_3$ will be a 18-month for the spot rate:

$\to 1.25\% \times \frac{100}{2} \times 0.99+1.25\% \times \frac{100}{2} \times \frac{1}{(1+\frac{3.300\%}{2})^2}+1.25\%\times\frac{100}{2} \times \frac{1}{(1+\frac{3.577\%}{2})^3}+(1.25\% \times \frac{\frac{100}{2}+100}{(1+\frac{r_3}{2})^4})=96\\\\$

to solve this we get $r_3=3.335\%$

Because services are inseparable, they cannot be tried before they are purchased. To counteract this, a service firm might:

Marina CMI [18]

Answer:

A, Offer a guarantee for the customer's complete satisfaction.

Explanation:

SInce services are inseperable beacuse there cannot be trials unlike in some goods, the only way to keep a customer's mind at rest over the service he or she is getting to give a guarantee as to the quality of the service such that the customer is satisfied and can purchase the service.

For example, giving a customer a time frame for the durability of a service and also a consideration for re-service before the set or supposed time is a way of giving customer guarantee about a service he or she is purchasing

Cheers.

Rios Co. makes drones and uses the variable cost approach in setting product prices. Its costs for producing 30,000 units follow

AnnyKZ [126]

Answer:

1. Variable cost per unit = $150

2. Markup percentage = 34.89%

3. Selling price = $202.33

Explanation:

Variable cost per unit = 70+40+25+15= $150

Fixed cost = 670,000+ 305,000 +285,000= $1,260,000

Fixed cost per unit = 1,260,000/30,000= $42

Profit per unit = Targeted profit

Targeted production unit

= $310,000 =$10.33

30,000

Markup percenge = Fixed cost per unit + profit per unit

Variable cost per unit

=$42+ $10.33 = 52.33 * 100 = 34.89%

$150 $150 1

Selling Price = Variable cost per unit + markup

= $150+$42+$10.33

= $202.33

Variable cost-plus pricing is calculated by determining variable costs per unit and adding mark-up which will cover fixed costs per unit and generate a targeted profit margin.
