The correct answer would be D, the median 86.5.
In this set of data most of the values are in the 80's or 90's. There is only 1 number that is outside of this range, that is the value 0. It is an outlier.
When we have an outlier, the median generally gives us the better measure of central tendency.
Let's translate the expression step by step:
"Five less than..." 
we will have to subtract five from something
"two times a number" 
.
So, we have
"Five less than two times a number" 
.
This "is sixty-nine", where "is" means "is equal to". So, the equation is
which is option B
The rule is to subtract 6
Answer:
B
Step-by-step explanation:
When you look at the triangle look at the 3 vertices. Now look at you answers given and choose one that combines all 3 vertices. You don't want your answer to contain a letter/number that represents the length of a side.
So in this case you don't want M or Y in you answer.
Your answer has to be made up of A X andT.
The only answer that uses AXT is answer B.
120 cm=120 cm*(10 mm/1cm)=1200 mm,
Ratio: 1200 mm / 80 mm=15/1
Answer:
C. 15 to 1
