Answer:
Probability that first sock is blue is 0.33 and Probability that second sock is red is 0.16
Step-by-step explanation:
Number of red socks = 2
Number of white socks = 6
Number of blue socks = 4
Total socks in drawer = 2+6+4 = 12
The formula used to calculate probability is: ![Probability=\frac{Number \ of \ favourable \ outcomes}{Total \ number \ of \ outcomes}](https://tex.z-dn.net/?f=Probability%3D%5Cfrac%7BNumber%20%5C%20of%20%5C%20favourable%20%5C%20outcomes%7D%7BTotal%20%5C%20number%20%5C%20of%20%20%5C%20outcomes%7D)
We are given you draw out a sock, return it, and draw out a second sock.
We need to find the probability that the first sock is blue and the second sock is red?
Using formula:
Probability that first sock is blue = 4/12 = 1/3 = 0.33
Probability that second sock is red = 2/12 = 1/6 = 0.16
So, Probability that first sock is blue is 0.33 and Probability that second sock is red is 0.16
Answer:
n < 3
Step-by-step explanation:
6n + 10 < 4n + 16
( Minus 4n from both sides to isolate + 16 )
2n + 10 < 16
( Minus 10 from both sides to isolate 2n )
2n < 6
( Divide both sides by 2 to isolate n )
n < 3
Plane #1 speed: x mph
Plane #2 speed: (x+30) mph
time = time becomes
170 mi 185 mi
---------- = --------------
x x+30
Solving for x, the speed of the slower plane, we get
170x + 5100 = 185 x
5100
Then 15x = 5100, and x = ---------- (mi/hr) = 340 mph
15
The slower plane flies at 340 mph, and the faster one at 370 mph.
We have that
Profit margin is calculated by finding the net profit as a percentage of the revenue
Profit margin = [Net profit / Revenue]
Net profit= [Revenue-Cost]
we know that
Revenue = $16.25 million
Cost = $13.5 million + $2.7 million
Net profit = [16.25 million - (13.5 million + 2.7 million)]
Net profit = $0.05 million
Profit margin = 0.05 / 16.25
Profit margin = 0.003077 or 0.3077%
