Answer:
1st: 22, 2nd: 27, 3rd: 88
Step-by-step explanation:
Make an equation
If she recieved x calls the 1st evening, then the 2nd evening she recieved x+5, and the 3rd evening she recieved 4x.
x+x+5+4x=137
Combine like terms
6x+5=137
Subtract 5 from both sides
6x=132
Divide by 6 on both sides
x=22
First:
22 calls
Second:
x+5
22+5
27 calls
Third:
4x
4*22
88 calls
Hope this helps!
I think the answer is A. That's a weird version of a growth factor formula.
I HAVE THE FOLLOWING APPROACH
WE KNOW THAT THE MEAN IS 17,
WE ADD ALL THE NUMBERS AND GET 142+A+B= 17*10
142+A+B=170
A+B=28
NOW MEDIAN IS 18,
WE HAVE 10 NUMBERS, THAT MEANS THE MEDIAN WILL BE (17+B)/2=18
B=19
A=9
THESE ARE YOUR NUMBERS

Answer:
(a) 10!
(b) 9!
(c) 2!9!
Step-by-step explanation:
(a)
Total number of members = 10
We need to line up the ten people.
Total number of ways to arrange n terms is n!. Similarly, total number of ways to line up the ten people is

Therefore the total number of ways to line up the ten people is 10!.
(b)
Let groom is immediate left of the bride it means both will sit together. So we need to arrange peoples for total 9 places (8 of others and 1 of bride and groom).

Therefore the number of ways to line up the ten people if the groom must be to the immediate left of the bride in the photo is 9!.
(c)
Let groom is immediate left of the bride it means both will sit together. So we need to arrange peoples for total 9 places (8 of others and 1 of bride and groom).
Bride and groom can interchange there sits.
Total number of ways to arrange bride and groom = 2!

Therefore the number of ways to line up the ten people if the groom must be next to the bride (either on her left to right side) is 9!2!.
