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:
Elizabeth washes 99 windows each day.
Step-by-step explanation:
Given:
Total number of windows (N) = 2480
Marie washes windows = 4 times Elizabeth washes.
Elizabeth washes same number of windows for 5 days.
Let the number of windows washed by Elizabeth each day = 'x'.
Therefore, over the 5 days, the windows washed by Elizabeth = ![5x](https://tex.z-dn.net/?f=5x)
Now, as per question:
Marie washes windows = 4 times Elizabeth washes.
So, number of windows washed by Marie = ![4(5x)=20x](https://tex.z-dn.net/?f=4%285x%29%3D20x)
Now, total number of windows = Windows washed by Marie + Windows washed by Elizabeth
So,
![2480=20x+5x\\\\2480=25x\\\\x=\frac{2480}{25}\approx99](https://tex.z-dn.net/?f=2480%3D20x%2B5x%5C%5C%5C%5C2480%3D25x%5C%5C%5C%5Cx%3D%5Cfrac%7B2480%7D%7B25%7D%5Capprox99)
Therefore, Elizabeth washes 99 windows each day.
