We know that the least square regression line is given by the equation:

y = a+b x

Here is the Y-intercept of the line and is the slope of the line that is, angle made with the horizontal axis or corresponding change in Y when X increases by one unit. This implies that the least square regression lines are completely determined by the slope and the intercept as given in the above equation.

Now if this line is found to be horizontal as shown in the figure below then it can be easily observed from the figure that the horizontal least square regression line makes no angle with the horizontal axis of the independent variable and thus is parallel to it.

Give your best everyday, be intentional, don't be afraid of correction and simply be there. Even when you don't feel like it work hard. Work ethic is one of the most important if not the most important thing bosses look at. Be intentional, know what you are doing and do it on purpose. If you don't pay attention to what you are doing then you will make mistakes and its hard to keep a long term job when all your boss remembers is getting on to you for countless careless mistakes. Don't be afraid of correction be thankful that someone took the time to help you get better. finally be there I had a friend who recently got a major promotion simply because he showed up and did what he was asked. it's strange how easy it is too do all these things and so many still don't. 
Hope this helps :).

If fixed costs do not​ change, then marginal cost A. equals the change in average variable cost divided by the change in output.
babunello [35]

Answer:

B. Equals the change in variable cost divided by the change in output

Explanation:

All those business expenses which are independent on the level of goods or services that the company produces are included in the fixed costs. These include lease and rent payments, insurance, salaries, interest payments etc.

The change in total cost which arises due to the increment in the cost of produced good by one unit is termed as marginal cost.

When fixed cost is not changing, the marginal cost is calculated by dividing the difference in total cost by difference in output.

quester [9]

Answer:

Option (B) is correct.

Explanation:

Given that,

Issued preferred stock outstanding that pays dividend per year = $7.75

Current selling price = $68.19 per share

Required return = (Annual dividend ÷ Current price)  × 100

                            = ($7.75 ÷ $68.19) × 100

                            = 11.37% (Approx)

Therefore, the required return is 11.37% if this issue currently sells for $68.19 per share.
