Answer: the distance is 8
Step-by-step explanation:
Answer:
Since there are 2 possibilities for each bat (hit or out), the amount of total possibilities is 2 * 2 * 2 = 8. There is only one possibility out of those eight that gives us three hits, therefore the probability is 1 / 8 or 0.125.
Formula:
V = 1/3 * b^2 * h
Plug in what we know:
V = 1/3 * 7^2 * 16
Simplify the exponent:
V = 1/3 * 49 * 16
Multiply all 3 numbers together:
V = 261.3cm^3

Answer:
80 and 90 mph
Step-by-step explanation:
Given that A and B have a distance of 1029 miles between them. Two trains each start from A and B and move towards each other.
Let the speed of I train be s
Then speed of second train = s+10 (since 10 greater than speed of I train)
Relative speed = s+s+10 = 2s+10
In 5 hours they travelled together a distance of 1020-170 =850 miles
Distance travelled = 850 miles
Relative speed = 2s+10
Time taken = 5 hours
Since distance = time x speed
we have
5(2s+10) =850
2s+10 =170
s = 80
Speed of the trains are 80mph and 90 mph
