Answer:
7/8
Step-by-step explanation:
Odds against are the ratio between losses and wins.
odds against = L / W
Probability of winning is the ratio between wins and all games.
probability = W / games
probability = W / (W + L)
The odds against are 1 to 7.
1/7 = L / W
W = 7 L
The probability is therefore:
P = (7 L) / (7 L + L)
P = 7/8
Because M is a midpoint of AB, |MB| = 4,
N is a midpoint of BC, |BN|=3.
From the picture we see that MB and BN are the legs of the triangle MBN, where MN is a hypotenuse.
Using Pythagorean theorem
MN²=MB²+BN²
MN² = 4² + 3² = 25
|MN| = 5
Answer is |MN| = 5
Step-by-step explanation:
The speed of sound has nothing to do with "sea level" and sound pressure and without the medium air there is no speed of sound. In SI units with dry air at 20°C (68°F), the speed of sound c is 343 meters per second (m/s). This also equates to 1235 km/h, 767 mph, 1125 feet per second (ft/s), or 666 knots.
