Do you remember when you were learning about
Least Common Multiple (LCM) ? And you were
wondering what on Earth you would ever need it for ?
THIS IS IT !
The amount of time after 8 PM when the lights will flash
together again is the LCM of 20 seconds and 30 seconds.
Do you remember how to find it ?
... When 20 is prime-factored, you have 2 · 2 · 5 .
... When 30 is prime-factored, you have 2 · 3 · 5 .
... So the Least Common Multiple of 20 and 30 is 2 · 2 · 3 · 5 = 60 .
The lighthouses will flash together again in 60 seconds after 8 PM.
That'll be 8:01 PM.
Given:
Let's evaluate and find the quotient.
We have:
SInce it is not a repeating decimal, we are asked to leave to answer as it is.
A repeating decimal is a decimal with digits or group of digits that repeats endlessly.
The decimal 5.937
ANSWER:
5.9375
Answer:
11.6 (6 is repeating)
Step-by-step explanation:
1.75 divided by 15% of 75
Answer:
YES
Step-by-step explanation:
Yes, the probability can be found through the binomial probability formula.
Binomial probability is used when there are two possible outcomes. The success (p) and failure (q) must be clear. Here, in the question if we need to find out the probability if live entertainment had increased the amount of money spent, then the percentage increase will be considered as success.
While if we want the probability that there is no change in the percentage of money spent, then it will be considered as failure.
