Consider a large number of countries around the world. There is a positive correlation between the number of cell phones per per

son, x, and the average life expectancy, y. Does this mean that we could increase the life expectancy in Rwanda by shipping cell phones to that country
A. No: if the correlation were negative we could accept that conclusion, but this correlation is positive.
B. No: the positive correlation just shows that richer countries have both more cell phones and higher life expectancies. We don't know if there is causation.

D. Yes: the correlation says that as cell phones go up, it causes life expectancy to go up.

agasfer [191]

Answer:

e. none of the choices.

Explanation:

Based on the scenario being described within the question it can be said that  none of the choices are correct because this method focuses on obtaining an order quantity by fixing the quantity for a certain period of time, and calculating the total quantity of Net Requirements within the period.

Suppose the economy is operating at a point where output is less than the natural level of output. Which of the following statem
laiz [17]

Answer: a) the price level is less than the expected price level.

Explanation:

When the actual output in an economy is lower then the natural output it is called a Contractionary Gap and the price level will be lower.

This is because the Short Run Aggregate Supply Curve and the Demand curve will intersect at a lesser quantity which will equate to a lower price as well because the economy is producing less and the people are demanding less as well so the point at which they meet will be a lesser price.

John Smith works 40 hours for ABC Corp. for $15 per hour. Required payroll deductions are: Social Security $37.20, Medicare $8.7
finlep [7]

Answer:

salary and wages increase by $600

Explanation:

given data

work = 40 hours

per hour cost = $15

Social Security = $37.20

Medicare $8.70

federal income tax = $58

state income tax = $10

solution

as we know that

Federal Unemployment are $4.80  and Social Security is  $37.20

Medicare =  $8.70  and state Unemployment  $24.6

so total  payable in form of salaries and wages increase $675.3 than actual pay $600

and when salary is paid by company it is for expenditure

and salary and wage payable account is debited

so cash account and state and federal tax payable is credit

so that entry record increase the expenditure

so salary and wages increase by $600
