Answer:
y = 0
Step-by-step explanation:
-4y - 19 = -19
add 19 to both sides:
-4y = 0
divide both sides by -4:
y = 0
Answer:
84.78%
Step-by-step explanation:
Data provided in the question:
P( Infection occurred ) = 4% = 0.04
P( Repair fails ) = 12% = 0.12
P( Both infection and failure occur ) = 0.78% = 0.0078
Now,
P( operations succeed and are free from infection )
= 1 - P( Failure ∪ Infection )
also,
P( Failure ∪ Infection )
= P( Infection occurred ) + P( Repair fails ) - P( Both infection and failure occur )
or
P( Failure ∪ Infection ) = 0.04 + 0.12 - 0.0078 = 0.1522
Therefore,
P( operations succeed and are free from infection )
= 1 - P( Failure ∪ Infection )
or
= 1 - 0.1522
= 0.8478
or
⇒ 0.8478 × 100% = 84.78%
100 - 83.5 = 16.5 [three significant figure]
2.45 + 18.3 = 20.75 [four significant figures]
Option b is correct.
As soon as I read the first line and saw the words "in this table", I knew in my
guts that when I opened the question and saw the whole thing, there would be
no table. So I opened it and, sure enough, my guts were correct again.
Nobody ... including you ... can answer this question without seeing the table.
Maybe that's been your whole problem, and the reason you're having trouble
with it. Sit down, relax, and spend some time with the table.
