Answer:
30240 number of ways are there to seat them
Step-by-step explanation:
Total number of ways of arranging 9 people on 9 chairs in circular manners = (9-1)! = 8! =
number of ways A sit always sit next to B = AB together makes a single and
therefore total number of arrangements for this = 7+(AB) = 8 that is 8 persons sitting in circular manner
number of ways = (8-1)! =7! = 5040
likewise number of arrangements for A and C will be = 5040
Total number of ways such that A cannot sit next to B or C = total ways of 9 persons - total number of A always sitting next to B - total number of ways always sitting next to C = 8! - 7!-7!
= 40320- 5040-5040
= 30240
=
Propably 4 and negative 2
Proportional us the correct answer
Answer:
- 0.167 < 0.5 ≤ 1.167
means 1/2 is -0.167 less
and 1/2 is equal to 1.167 when 2/3 is set to distance each way.
Step-by-step explanation:
we can evaluate what 2/3 equals by equating the number to decimal
0.33 = 1/3 so 0.667 = 2/3
We then just subtract and add to 1/2
0.5 + 0.667 = 1..167
0.5 - 0.667 = -0.167
Answer:
The new population is 5,500,000
Step-by-step explanation:
You would just add 10% to 5,000,000 to get the total population. Hope this helps! :)
