If a package is damaged, the probability that it came from Manufacturer A is 62.5%.
Given that two manufacturers supply paper cups to a catering service, and manufacturer A supplied 100 packages and 5 were damaged, while Manufacturer B supplied 50 packages and 3 were damaged, to determine, if a package is damaged, the probability that it came from Manufacturer A, the following calculation must be performed:
- 5 + 3 = 100
- 5 = X
- 5 x 100/8 = X
- 62.5 = X
Therefore, if a package is damaged, the probability that it came from Manufacturer A is 62.5%.

Answer:
Points of intersection: (1.225,-1.58) and (1.225,1.58)
Step-by-step explanation:
Given
Required
The region area
Plot the graphs of and
Make y the subject in both equations
Square both sides
Rewrite
Take square roots
So, we have:
Take square roots
So, we have:
The point of intersection is:
Square both sides
Collect like terms
Divide by 2
Take square roots
So, the point of intersection is at: (1.225,-1.58) and (1.225,1.58)
<em>See attachment</em>
From the attached image, we can see that the curves do not enclose
Hence:
Answer:
<em>x = 14</em>
Step-by-step explanation:
-1/5 (x - 4) = -2
Multiply both sides by -5.
x - 4 = 10
Add 4 to both sides.
x = 14
