The time to assemble the first unit on a production line is 8 hours. The learning rate is 0.81. Approximately how long will it take for the seventh unit to be assembled?

4.428 hours

Step-by-step explanation:

If the learning rate is 0.81, the slope of the learning curve is:

The time it takes to produce the n-th unit is:

If T1 = 8 hours, the time required to produce the seventh unit will be:

It will take roughly 4.428 hours.

use an equation of ratios to determine the amount of gas needed to fill the tank.

    0.2             0.8

  =    

288.75             x

                                                              231 gal

so, 0.2x = (0.8)(288.75 gal), and x = = 1155 gal.

                                                                0.2

it would take 1155 gal. to fill the tank.

the cost would be

1155 gal         $3

* = $3465   (answer)

      1           1 gal

hope this you

1 + (6 / x - 1)
