Answer:
Step-by-step explanation:
Given that a manufacturer makes three types of screws
Type A B C Total
Pack 1000 500 800
P for flaw 0.001 0.03 0.005
Pack*p 1 15 4 20
a) Expected total number of defective screws = 20
b) For one pack each no of defective screws =20
Hence for 5 expected number number of packs form each should be 1/3
There are NO SOLUTIONS.
Substitute the first equation for y in the second equation. You can see it does not work. 6 does not equal 8. Therefore there are no solutions.
Answer:
y = 4
Step-by-step explanation:
Note that A and B have the same x-coordinate: 1. This means that AB is a vertical line through x = 1. The perpendicular bisector of AB must be a horizontal line situated halfway between y = 3 and y = 5. Thus, it's just y = 4.
Review: y = 4 bisects AB and represents a horizontal line.
