Why must you repeat steps three and four in the scientific method?

1 answer:

6 0

<span>We repeat steps three and four in the scientific method such as to form a hypothesis and conduct an experiment in order to arrive at the perfect answer to the question and provide a right direction to further scientific investigation and most importantly in order to verify the results. Since different science disciplines have different criteria for determining what good results are. “Practice make perfect” is apparently true for the experimentation in order to develop skills which is necessary to extend established methods and develop new experiments. Lastly, The experiment must also be reproducible so that it can be tested for errors.</span>

Feliz [49]

Answer:

If Verizon charges an optimal two-part price thenconsumer surplus will be zero.

Explanation:

Given a competitive market the consumer surplus will be the area of the demand curve above the market price

This is, between the intersection point with Y axis and a parallel at market price. Ofter represent as a triangle

If a monopolistic company maximize profit It will decrease this consumer surplus as much as it can to gain it from itself.

First it will set price equal to his marginal revenue.

Then, if possible it will charge two tariff a fixed component and a variable component per usage This will extrac all consumer surplus in favor of the firm leaving a consumer surplus of zero.

If Verizon charges an optimal two-part price thenconsumer surplus will be zero.

A shift in a PPC/PPF to the right (or outward) illustrates Growth which may be generated by __________________ (better utilizing

Elina [12.6K]

Answer:

The correct answer is economic growth.

Explanation:

A production possibility curve or frontier shows the different combinations or bundles of two goods that can be produced using limited resources. The curve is concave because of increasing opportunity cost.

An outward shift in the production possibility curve shows an increase in the level of production. This can happen because of two reasons ,

Increase in the quantity of resources available , and
Improvement in technology

Both of these factors will help in increasing the level of production. In other words, we can say that the outward shift in the production possibility curve shows economic growth.

A publicist's compensation package includes the total cost of a $180-per-

natima [27]

Answer:

D. $44,580

Explanation:

Here we want to find the yearly value of the compensation package.

To order to do so, we have to add the various terms. We have:

$t_1=\$42,000$ salary per year

Then we have the total cost of a $180-per- month health insurance plan; since there are 12 months in a year, it is

$t_2=12\cdot \$180 =\$2160$ per year

Then we have the total cost of a $35-per-month life insurance, so the yearly cost is

$t_3=12\cdot \$35 =\$420$

Therefore, the total compensation package is

$T=t_1+t_2+t_3=42000+2160+420=\$44,580$

So, option D.

A workgroup of 5 workers produced 500 units of output in a certain month working 22 days (8 hours per day).

Sedbober [7]

Answer:

The question continues ; b) Suppose that in the next month, the same work group produced 600 units but there were only 20 workdays in the month. Using the same productivity measures as before, determine the productivity index using the prior month as a base.

Explanation:

given 5 workers produced 500units working 8hrs/day for 22days

We calculate the output unit for each per worker for a month, a day and an hr;

Monthly output unit = 500/5 = 100 = LPR = Productivity ratios

daily output unit = 500/ 5x22 = 4.545 = LPR

hourly output unit = 500/ 22x8x5 = 0.568 = LPR

similarly for 600units produced by the same number but in 20days

Monthly output unit = 600/5 = 120 = LPR = Productivity ratios

daily output unit = 600/ 5x20 = 6.0 = LPR

hourly output unit = 600/ 20x8x5 = 0.75 = LPR

To calculate their productivity index ;

LPI = 120/100 = 1.2 = Monthly output unit

LPI = 6.0/4.545 = 1.32 = daily output unit

LPI = 0.75/0.568 = 1.32 = hourly output unit
