A- the answer is 2, because it has the most amount of crosses or is the highest bar, showing that it is the most popular (mode)
mean is adding all the numbers divided by how many numbers there are, so 20/10=2
median is the number in the middle of an (ordered) row. but since the numbers are already ordered, it is in between 33 and 35, so the median is 34
C and D since they both show the most and least popular result, rather than estimating percentages.
D because each sample adds up to 200.

Answer:
Step-by-step explanation:
Why?
Let y + z = t. Then
Use
Come back to substitution:
Use (*) and the distributive property: <em>a(b + c) = ab + ac</em>
You wanna get the y by itself. So you will subtract 11.9 then move it to the other side. so that is 10.5y = -11.9x +178.5. Then divide everything by 10.5. Then you get y = -11.9x/10.5+17. 11.9x/10.5 is because you cant put 10.5 into 11.9 evenly so you leave it as a division problem.
