The given data suggests an association between fuel efficiency and engine displacement. The regression model defined is: Mpg = 36.25 – 3.867 Engine size. Residuals are determined by the difference between actual and predicted values. Residual = y - ŷ, where y signifies the actual value and ŷ denotes the predicted value. A positive residual indicates the vehicle's true mileage surpasses what was anticipated.

stepan [3001]

Response:

The yearly average return stands at 9.6 %

Clarification:

Calculating the average return

Assuming the price per share is 100

                                                       Initial    Growth             Final

                                                         Value            %                   Value

Company A  50 % at 100                5,000              8 %                 5,400

Company B 30 % at 100                 3,000              12 %                3,360    

Company C 20 % at 100                  2,000             10 %                2,200

Total amounts                             10,000                                     10,960

To find the average return, take the increase in value over the base, divided by the base

10,960 -  10,000  =  960/ 10000  = 9.6 % average return

Mariulka [3175]

Klingon Widgets, Inc., purchased new cloaking machinery three years ago for $6 million. The machinery can be sold to the Romulan
arsen [2965]
a. The current total asset value for Klingon is calculated as follows: total assets equal net fixed assets plus current assets. Here, net fixed assets are $3,400,000, and current assets total $1,130,000, which is derived from net working capital plus current liabilities ($235,000 + $895,000). Hence, total assets amount to $3,400,000 + $1,130,000, leading to a total of $4,530,000. b. The market value of net working capital stands at $1,150,000, and the market value of fixed assets is $5,100,000. Therefore, when these figures are combined, the total fair market value amounts to $1,150,000 + $5,100,000, which equals $6,250,000.
