In your shoes I would look up "mean," "median" and "mode" to be certain of what they mean. That knowledge (or lack of it) will certainly affect your course grade.
Rearrange the nine given numbers in ascending order: 135, 135, 142, 150, 168, 173, 178, 184, 193.
The mode is the number that shows up most often. That'd be 135. No other number shows up twice.
The median is the middle number of the rearranged seet. That'd be 168.
The mean is the arithmetic average of the 9 numbers. To find that, add up the numbers and divide your sum by 9:
135+135+142+150+168+173+178+184+193
mean: ---------------------------------------------------------------- = 162

Using the pythagorean identity, we can find the value of sin(A)
cos^2(A) + sin^2(A) = 1
(12/13)^2 + sin^2(A) = 1
144/169 + sin^2(A) = 1
sin^2(A) = 1 - 144/169
sin^2(A) = 169/169 - 144/169
sin^2(A) = (169 - 144)/169
sin^2(A) = 25/169
sin(A) = sqrt(25/169)
sin(A) = 5/13
Which is then used to find tan(A)
tan(A) = sin(A)/cos(A)
tan(A) = (5/13) divided by (12/13)
tan(A) = (5/13)*(13/12)
tan(A) = (5*13)/(13*12)
tan(A) = 5/12
The final answer is 5/12
The event will have 27 tables, with 2 adults and 3 children in each table.
Step-by-step explanation:
The greatest number of tables the planner can set up is determined by finding the greatest common factor in 54 and 81. This is given by;
54 81----------------divided by 3
3 18 27---------------divided by 3
3 6 9---------------divided by 3
3 2 3---------------no common divisor
The greatest number of table will be given by : 3×3×3=27
The number of adults in each table will be 2
The number of children in each table will be 3
