Question:
Members of a dancing club are asked which of four Latin dances they performed most recently. Their responses are summarized in the incomplete two-way relative frequency table below.
What percent of the members are ages 31 to 50 and most recently danced the samba?

Table Provided
MerengueBachataSambaPasilloTotal
Ages 18 to 303%18%11%
Ages 31 to 507%4%1%
Ages 51 to 7510%5%7%34%
Total32%17%100%


---------------------------------------------------------
---------------------------------------------------------

I'll write A,B,C,D,E,F,G in the 7 blanks as shown below.
MerengueBachataSambaPasilloTotal
Ages 18 to 303%18%11%AB
Ages 31 to 507%4%C1%D
Ages 51 to 75E10%5%7%34%
TotalF32%G17%100%


It should be fairly clear that A or E is the best choice to start with.
I'll go with E.

Along the third row, the percentages must add to 34%
E+10+5+7 = 34
E+22 = 34
E = 34-22
E = 12
We'll replace E with 12%
MerengueBachataSambaPasilloTotal
Ages 18 to 303%18%11%AB
Ages 31 to 507%4%C1%D
Ages 51 to 7512%10%5%7%34%
TotalF32%G17%100%


Then add up the items in the first column
3+7+12 = 22
Therefore we replace F with 22%

Ages 18 to 303%18%11%AB
Ages 31 to 507%4%C1%D
Ages 51 to 7512%10%5%7%34%

I'll let the student take over from here.

             M     B    S    P  Tot.
Ages 18-30 | 3% | 18%| 11%|  A%|  B%|    
Ages 31-50 | 7% |  4%|  C%|  1%|  D%|    
Ages 51-75 | E% | 10%|  5%|  7%| 34%|
-----------|----|----|----|----|----|    
Total      | F% | 32%|  G%| 17%|100%| 

Use the P column to find A, and the Ages 51-75 row to find E
Fill those in.
Use the Ages 18-30 row to find B and the M column to find F
Fill those in.
Use the Tot. column to find D, and the Total row to find G
Fill those in.
Use the Ages 31-50 row to find C and as a check on C use column S.

Now you can answer the question.

But one of the other tutors will probably have done it all for you
so you won't have to do a thing but copy it and turn it in.  No
learning required.

Later: I was right. Copy it, turn it in, and learn nothing!
Still later. I was wrong! Two other tutors did it for you, not just one.
Happy copying, turning in, and nothing-learning! J

88-C84919-4126-48-DC-90-BB-9-C73110864-A9
