Answer:
required probability is .3446
Step-by-step explanation:
It is given that most expected time of completion = 90 days
Variance = 25
We know that
Thus the standard normal deviate is given by
Applying values we get
Using the standard table for Z we have probability corresponding to Z = -0.4 equals 0.3446
Thus required probability is .3446
Answer:
1.63 Kilograms
Step-by-step explanation:
I started by finding out what the roast beef weighed. Then I added 740, 520, and 370 (what the roast beef weighs). I can work that way because they are all in grams. The total off all that equals 1630 grams. Then I converted that to kilograms. Which will end up giving you 1.63 kilograms.
