C is the answer.
We multiply the top and bottom of this by the conjugate (switch the sign of the square root):
(2-sqrt8)(4-sqrt12)/(4+sqrt12)(4-sqrt12)
Multiying the top we have
8-2sqrt12-4sqrt8+sqrt(8×12)
Multiplying the bottom we have:
16-4sqrt12+4sqrt12-12
On top, we simplify the radicals and get
8-4sqrt3-8sqrt2+4sqrt6
On bottom, we have
16-12=4
Now we divide everything on top by 4 and get
2-sqrt3-2sqrt2+sqrt6
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%
Answer:
the length is 84 ft
Step-by-step explanation:
65*2= 130
298-130=168
168/2=84
84+84+65+65=298 ft
Denise rode 3 kilometres .
Clark rode 5000 metres which is 5 kilometres .
So , Clark rode 2 kilometres more than Denise .
