A 30
The circumference of a circle is ![2\pi r](https://tex.z-dn.net/?f=2%5Cpi%20r)
Circumference = ![2\pi (3) = 6\pi](https://tex.z-dn.net/?f=2%5Cpi%20%283%29%20%3D%206%5Cpi)
It says to leave in terms of pi which means that we won't solve ![6\pi](https://tex.z-dn.net/?f=6%5Cpi)
Thus the answer is
.
Hope that helped!
Answer:
Order Data (least to greatest): 35,40,42,46,47,52
Mean: 43.66
MAD:4.66
Could not figure out Mean of Differences sorry!
Step-by-step explanation:
To find the mean you add all of the numbers and divide by the amount.
To find MAD find the sum of the data values, and divide the sum by the number of data values.
Let Julio's normal hour rate is $x .
So we have
![31x + (41-31)*1.2 x = 550.40 \\ 31x +10*1.2x = 550.40 \\ 31x+12x = 550.40 \\ 43x= 550.40 \\ x = \frac{550.40}{43}=$12.80](https://tex.z-dn.net/?f=%2031x%20%2B%20%2841-31%29%2A1.2%20x%20%3D%20550.40%0A%5C%5C%0A31x%20%2B10%2A1.2x%20%3D%20550.40%0A%5C%5C%0A31x%2B12x%20%3D%20550.40%0A%5C%5C%0A43x%3D%20550.40%0A%5C%5C%0Ax%20%3D%20%5Cfrac%7B550.40%7D%7B43%7D%3D%2412.80%20)
So Julio's hourly rate is $12.80.
And this is reasonable , since working 41 hours at a rate of $ 13 per hour is
![=41(10+3)=410+123=533](https://tex.z-dn.net/?f=%20%3D41%2810%2B3%29%3D410%2B123%3D533%20)
is close to 550.40 .
