Answer:
Noah did not make any error
Step-by-step explanation:
The median of a list of strictly increasing numbers is simply the middle number. If there's an even number of numbers in the list, then the median is the average of the middle two terms.
Here, the numbers are 115, 109, 117, 136, 127, 131. When ordered from least to greatest, we get: 109, 115, 117, 127, 131, and 136, which is what Noah got.
Since there are 6 numbers (6 is even), the median will be the average of the middle two numbers, which are 117 and 127: (117 + 127)/2 = 244/2 = 122
So, Noah was correct.
Answer:
19) (
)^2 = 
20) -
= -81
21)

Step-by-step explanation:
The only wrong ones are
19) (
)^2 = 
20) -
= -81 ... negative is not inside a parenthesis that's why it is still negative
21) you can add another way is
= 16
Everything else looks good. Great job!
I'm assuming you mean which one is written properly? It would be either 3 x 10^4 or 6 x 10^4.
Hope it helps!
