Answer:
We conclude that the 76% is of the learning in this process.
Step-by-step explanation:
We know that the company Z is just starting to make a brand new product it has never made before. It has completed two units so far. The first unit took 29 hours to complete and the next unit took 22 hours. We calculate the estimate of the learning percentage in this process:
22/29 = 0.76 = 76%
We conclude that the 76% is of the learning in this process.
Answer:
Option D (r(t) = 3.50t +25
; r(8) = 53)
Step-by-step explanation:
The fixed cost to rent the kayak $25. This is the cost which remains fixed irrespective of the usage of the kayak. The variable cost of using the kayak is the cost which depends on the usage of the kayak. It is mentioned that the kayak is used for 4 hours and the company charges $3.5 for every half hour. The cost function is given by:
r(t) = 25 + 3.5t ; there r is the total cost of using the kayak and t is the number of half-hours the kayak is used.
4 hours means that there are 8 half-hours. Therefore, t=8. Put t=8 in r(t).
r(8) = 25 + 3.5*(8) = 25 + 28 = 53.
Therefore, Option D is the correct answer!!!
To find decimal and percent, we have to simplify the denominator to 100. To do this, we divide both sides by 2:
3/200 = 1.5/100
The decimal would be 0.015, and the percent would be 1.5%
200,000 because you round it up.
