The expanded binomial is 2x^3+3y^2=7
<u>Step-by-step explanation</u>:
- The binomial is not shown in correct expansion. It is written in the wrong format. There is a general format for the binomial expansion.
- The first term should have the highest power. So 2x power 3 will come first. The second term will have power lesser than the first term.
- So in the second term, 3y^2 will be placed. After that, the equal to = operator will be placed. Finally, the value of the expression will be placed.
- So the expanded correct form is 2x^3+3y^2=7
Answer:
6 is your median and the average is 11.7
Step-by-step explanation:
to find the median, you simply list the numbers in order from greatest to least and determine which is in the middle.
(3, 4, 5, 6, 16, 20, 28 - with 6 there is three numbers on the left and three numbers on the right)
to determine the average, you add all the numbers up and divide by how many numbers you have
3 + 4 + 5 + 6 + 16 + 20 + 28 = 82
82 divided by 7 is 11.71428571 (when simplified its 11.7)
