Answer:
a) 40320 ways
b) 384 ways
Step-by-step explanation:
a) if there are no seating restrictions, the number of ways the 4 couples can be seated is the permutation of 8 persons in 8 seats then
number of ways= permutation of 8 persons in 8 seats = 8! = 40320
b) if each couple will sit together then the number of ways is:
number of ways= number of permutation of 4 integrants of each couple in 4 pairs of seats * number of permutation for a couple in a pair of seats^ number of pair of seats = 4! * 2^4 = 384
> less than should be the answer
4-3.42=0.58 What i did was subtract four from three dollars and forty- two cents, And i got 0.58.
Answer:
4374
Step-by-step explanation:
Since, we are given table for x and y values
and table for average rate of changes
we can see the pattern of average rate of change
average rate of change for 5 to 6 is three times average rate of change for 4 to 5
but we have to find
average rate of change for 7 to 8
so, using same pattern
average rate of change for 6 to 7 is three times average rate of change for 5 to 6
average rate of change for 7 to 8 is 3*3( average rate of change for 5 to 6)
so, we can plug value
average rate of change for 7 to 8 is 3*3*486
average rate of change for 7 to 8 is 4374
