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:
The answer is
<h2>a = 11, b = 7</h2>
Step-by-step explanation:

Multiply the terms on the left side of the equation
That's

Since the bases are the same we can equate the exponents
That's

a = 11
And

b = 11
Therefore
a = 11 and b = 7

Answer:
Jenna will complete remaining distance in 6 hours.
Step-by-step explanation:
Since we know that
. Let us find the rate at which Jenna traveled 100 miles.
