Answer:
a. 1/10 or 10%
b. 1/2 or 50%
Step-by-step explanation:
Since the combination of machines 1, 2 and 3 produce 100% of the total output when added together, then the probability of choosing a bolt at random that is defective is: 5 + 2 + 3 = 10% out of 100% or 10/100, which is 1/10 or 10%.
If the bolt that is choosen at random is defective, than the probability that it came from machine 1 is 5/10 or 1/2 which is also 50%.

Answer:
9y +9x - 10a-10c -10b = 105
Step-by-step explanation:
Given
a+b+c = -6 and x+y = 5
We have to find 9y +9x - 10a-10c -10b
Rearranging the terms
9x+9y-10a-10b-10c
Simplifying will give us:
= 9 (x+y) - 10(a+b+c)
Putting the values of x+y and a+b+c
= 9(5) -10(-6)
=45+60
=105
Therefore,
9y +9x - 10a-10c -10b = 105 ..
