Hip Breadths and Aircraft Seats
Engineers want to design seats in commercial aircraft so that they are wide enough to fit 98% of all males. (Accommodating 100% of males would be too expensive.) Men have hip breadths that are normally distributed with a mean of 14.4 in. and a standard deviation of 1.0 in. Find P 98. That is, find the hip breadth for men that separates the smallest 98% from the largest 2%.
Answer:
11 cups of dough
Step-by-step explanation:
1 cup x 11 dumplings = 11 cups of dough needed
Inversely variation means xy = c, where c is a constant
Since when y = 12 x = 5, then c = 12*5 = 60
So xy = 60
Now when x = 3, y = 60/3 = 20
3^3-2(5)^2-3(3)^3+-3(4)
27-50-81+-12
-116
15 and 16
Root of 234 is roughly 15.3
