The mean is when you add up all the numbers and divide by the amount of numbers there are.
143+312+41+28+308+619+321+352+465=2589
2589/9=287.666666667
round to the whole number you get
288
rational numbers can be written as a ratio of two integers a/b
1/2 is the ratio of 1 and 2 so its rational
√7/10 is not a ratio of two integers so its irrational
3π/4 is not a ratio of two integers so its irrational
5/9 is the ratio of 5 and 9 so its rational
18 is 18/1 and is the ratio of 18 and 1 so its rational
Answer:
Option 4
Step-by-step explanation:
Functions must pass the Vertical Line Test (VLT). Every input has to have exactly one output.
There are 10 seats in ferris wheel of love.
One couple can fit in to one seat. That means 1 couple per seat.
Given, in each minute a seat passes by the entrance or exit stage. That means one couple can use the seat for one minute. That means 1 seat per minute.
The wheel starts functioning at 8 p.m for half an hour. In 1 hour there are 60 minutes. So half an hour means
= 30 minutes.
So we have got 1 couple per seat and 1 seat per minute. If we multiply them we will get 1 couple per minute.
We have got in 1 minute there is 1 couple.
So in 30 minutes there are
couples = 30 couples.
We have got the required answer here.
There are 30 couples who took a ride in the ferris wheel of love.
