Answer:
The number of different ways are 22! or 1,124,000,727,777,607,680,000.
Step-by-step explanation:
Consider the provided information.
We need to determine the number of different ways can a class of 22 second graders line up.
We need to select 22 second graders while taking 22 at a time.
So use the permutation formula: 
Substitute n=22 and simplify.
Hence, the number of different ways are 22! or 1,124,000,727,777,607,680,000.
Answer:
fourth option
Step-by-step explanation:
Common difference is given by difference of two consecutive term
d = nth term - (n-1)th term
______________________________________
for all the series lets take second term as nth term
and first term as (n-1)th term
_________________________________________
for first series
n th term = -3 1/2 = -3.5
(n-1)th term = -5
therefore
d= -3.5 -(-5) = -3.5 +5 = 1.5
______________________________________
for second series
n th term = 4 1/2 = 4.5
(n-1)th term = 2 1/2 = 2.5
therefore
d= 4.5 -(2.5) =2
_________________________
for third series
n th term = 3
(n-1)th term =1.5
therefore
d= 3 - 1.5 = 1.5
__________________________________
for fourth series
n th term = -1.5
(n-1)th term = -4
therefore
d= -1.5 -(-4) = -1.5 + 4 = 2.5 = 2 1/2

Thus, based on above solution option four has common difference of 2 1/2
4x10(6)=4,000,000 1x10(4)=3,990,000
Answer:
Step-by-step explanation:
The formula for this is:
6(6 + x) = 3(3 + 25) and
6(6 + x) = 3(28) and
36 + 6x = 84 and
6x = 48 so
x = 8
Answer:
your answer to this is 68/25
