158
2(5•3)=2(15)=30
2(8•3)=2(24)=48
2(8•5)=2(40)=80
30+48+80=158
For this case we have the following data:
31, 32, 32, 33, 34, 35, 35, 35, 35
The median is given by the central datum:
Median = 34
Mode is given by the most repeated data:
Mode = 35
Answer:
Median = 34
Mode = 35
The correct simplification of x^12z^11/x^2z^4 is ![x^{10}z^{7](https://tex.z-dn.net/?f=x%5E%7B10%7Dz%5E%7B7)
<h3>How to simplify the expression?</h3>
The expression is given as:
x^12z^11/x^2z^4
Rewrite properly as
![\frac{x^{12}z^{11}}{x^2z^4}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%5E%7B12%7Dz%5E%7B11%7D%7D%7Bx%5E2z%5E4%7D)
Apply the quotient law of indices
![x^{12-2}z^{11-4}](https://tex.z-dn.net/?f=x%5E%7B12-2%7Dz%5E%7B11-4%7D)
Evaluate the difference
![x^{10}z^{7](https://tex.z-dn.net/?f=x%5E%7B10%7Dz%5E%7B7)
Hence, the correct simplification of x^12z^11/x^2z^4 is ![x^{10}z^{7](https://tex.z-dn.net/?f=x%5E%7B10%7Dz%5E%7B7)

Answer:
78.5 in
Step-by-step explanation:
Circumference = 2
r
Circumference = 2(3.14) x 12.5
Circumference = 25 x 3.14
Circumference = 78.5
