5 7/8 is 47/8
Because,
You multiply 5 and 8 and then add 7, then you keep the denominator.
Answer:
10% probability that the part has at least one flaw
Step-by-step explanation:
We have these following probabilities:
90% probability of the part being flawless.
8% probability of the part having a minor flaw
2% probability of the part having major flaws.
What is the probability that the part has at least one flaw
Minor or major flaws. So 8% + 2% = 10%
10% probability that the part has at least one flaw
With questions like this (to see if theyre parallel), all you have to do is see if lines have a congruent slope. if yes (ex: 2 and 2), then they are parallel. if the slopes are opposites (ex: 4 and -1/4), then they are perpendicular. If they have no such relation (ex: -3 and 1/7), then they are neither.
with this problem, find the slope by separating the same variable in each equations, like this:
2x + 7y = 6
-2x -2x
7y = -2x + 6
(the second equation is already separated) so now we have
7y = -2x + 6 and 7y = 2x + 6
since -2 does NOT equal 2, these two graphs/lines are NOT parallel.
Hope this helped!
