Remember if two lines are perpendicular, the product of their slopes are -1
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%.

Hey there
2/5 + 1/10 is a fraction
You multiply 2/5 by 2
2/5 = 4/10
<span>4/10 + 1/10 = 5/10
</span>
Now you reduce 5/10
<span>5/10 = 1/2 </span>
<span>1/2</span>
