Answer:
a) 0.01111
b) 0.4679
c) 0.33747
Step-by-step explanation:
We are given the following in the question:
The number of accidents per week can be treated as a Poisson distribution.
Mean number of accidents per week = 4.5
Formula:
a) No accidents occur in one week.
b) 5 or more accidents occur in a week.
c) One accident occurs today.
The mean number of accidents per day is given by
Subtract the thickness of the covers from the total thickness of the 500-pages book. Since each cover is 0.125 inches thick, double this value and subtract from 2.25 inches. This results to 2 inches. To determine the thickness of each of the pages, divide 2 inches by 500 pages. Therefore, the thickness of a single page is 4x10^-3 inch.
The 1st side is 13 yards, the 2nd is 18 yards, and the 3rd is 11 yards
Okay. All we have to do is look at this graph and see what points out of those answer choices show up. (-2, 4) is on the line (actually where the line intersects) but what about the others? (4, -2) and (4, 3) are not connected with any of the lines, so C and D are eliminated. (3, 4) is on the line, but that's not where both lines intersect. Intersecting lines at a point shows that the point is the solution, in this case (-2, 4) is the solution to this system of equation. The answer is A: (-2, 4).
