I'm using PEDMAS.
Multiplication first.
2 • 4 = 8
Subtraction.
20 - 4 = 16
16 + 8 = 24
Please let me know if you spot any errors (especially the fraction operation)
If the outliers are not included, what is the mean of the data? 76,79,80,82,50,78,83,79,81,82.

50 is the only outlier so take 50 out of the set then add the other 9 data points and divide by 9.<span>
76 + 79 + 80 + 82 + 78 + 83 + 79 + 81 + 82 = 720 / 9 = 80</span>
I think is A but not to sure
Answer:
3^-5
Step-by-step explanation:
Whenever you multiply exponents, you add the values. Negative two plus negative three results in an answer of negative five. This will be the power. You will end up with 3^-5 as your answer.
Substitute z with 3.
3(4)^3
Cube 4 with 3
3(64)
Multiply 3 and 64
