The probability that all three of the selected vials have hairline cracks = 0.096
Total number of vials in the shipment = 62
Number of vials with hairline cracks = 14
Number of vials without hairline cracks = 48
Three from 62 vials are selected.
So total outcomes = 62C3
Number of possible outcomes for all 3 of selected vials have hairline cracks = 14C3, which is the number of favorable outcomes
Probability that all three of the selected vials have hairline cracks = Number of favorable outcomes/Total outcomes = 14C3/62C3 = 0.096

A) 94.2 is the closest to the circumference of the base of the shipping drum
Here's the first equation:
w = l - 7
Knowing this:
l*w = 98
Input w:
l*(l - 7) = 98
l^2 - 7l - 98 = 0
Factor:
(l-14)(l+7) = 0
Length can't be a negative number, -7 is rejected
The length is 14, the width is 7
Answer:
Write the equation as x minus 89 = 7 and add 89 to both sides. The answer is 96.
Step-by-step explanation:
Difference means subtraction. So, x-89=7. To solve it, we are going to add 89 to both sides of the equation, which gives us x=7+89, which is x=96. So, the answer is the second one: Write the equation as x minus 89 = 7 and add 89 to both sides. The answer is 96.
