Step-by-step explanation:
I don't know if the first set of numbers is all in one set, but I'll do my best to give you an answer.
Really all you need to do is use PEMDAS for the first question.
(Parentheses, exponents, multiply, divide, add, subtract. In that order)

Then to simplify that fraction next to it, notice that 0.018 is 3x 0.06.
that's a 3:1 ratio, so it ends up simplifying to this:

Lastly, to solve the division of that fraction. If you divide by a fraction, you multiply whatever it's dividing by its inverse.
So...

Answer:
Mean- 5
Median- 6
Mode- 6
Step-by-step explanation:
1. Place the numbers in order from smallest to biggest.
0,2,3,4,5,6,6,6,7,8,8
Finding the mean (average)- add all the numbers in thd data set together. Which would be 55. Then, you would divide that number by the number of the numbers in the data set. (11 numbers.) 55/11. 55 divided by 11 is 5, so that is your answer.
Finding the median- This is why we put the numbers in order. We are finding the number that is directly in the middle of the numbers. Mark one on each side until you get to the number in the middle. In this case, the median number will be 6.
Finding the mode- This one is easy. It's simply the number that repeats itself the most. In this case it would be 6 because it repeats itself 3 times.
First, it says to simplify the expression, so you should try that first.
Simplified Expressions:
8y^15 and 36y^7
Then compare on which simplified expression has the greater exponent
8y^15 and 36y^7
8y^15 has the greater exponent
8y^15 = (y^9)(2y^2)^3 (Or the first expression)
The exponents of expression #1 are greater than the exponents of expression #2
