Distance Covered, D=1000 feet
Time taken, T=3 seconds
Therefore, Speed in feet per second is,
Now, to calculate the speed in miles per hour all that we have to do is to know the relationship between seconds and hour and feet and mile.
mile
We also know that there are 3600 seconds in 1 hour. Thus,
if in 1 second fireworks go 0.0631306818 mile
then in 3600 seconds (or 1 hour) they go miles
Therefore, the speed of the fireworks in miles per hour is:
222.27 miles per hour.
Conditional probablility P(A/B) = P(A and B) / P(B). Here, A is sum of two dice being greater than or equal to 9 and B is at least one of the dice showing 6. Number of ways two dice faces can sum up to 9 = (3, 6), (4, 5), (4, 6), (5, 4), (5, 5), (5, 6), (6, 3), (6, 4), (6, 5), (6, 6) = 10 ways. Number of ways that at least one of the dice must show 6 = (1, 6), (2, 6), (3, 6), (4, 6), (5, 6), (6, 6), (6, 5), (6, 4), (6, 3), (6, 2), (6, 1) = 11 ways. Number of ways of rolling a number greater than or equal to 9 and at least one of the dice showing 6 = (3, 6), (4, 6), (5, 6), (6, 3), (6, 4), (6, 5), (6, 6) = 7 ways. Probability of rolling a number greater than or equal to 9 given that at least one of the dice must show a 6 = 7 / 11
I believe x would equal 88 degrees, hope this helps!
Answer:
the numbers are 18 and 38
Step-by-step explanation:
x =smaller integer and y =larger integer
