Answer:
y=5
Step-by-step explanation:
Perpendicular means what will make a 90 degree angle off of it. We know that the line is X=5, which is a vertical line. Y=5 is a horizontal line. So when you have a vertical line, then put a horizontal line through it, you will get a 90 degree angle, meaning it is perpendicular.
55÷5 which then could be solved to get the answer of eleven.
The draws are independent, so
![P(\text{red then blue})=P(\text{red})\cdot P(\text{blue})](https://tex.z-dn.net/?f=P%28%5Ctext%7Bred%20then%20blue%7D%29%3DP%28%5Ctext%7Bred%7D%29%5Ccdot%20P%28%5Ctext%7Bblue%7D%29)
There is a total of 11 marbles in the bag, so
![P(\text{red})=\dfrac3{11}](https://tex.z-dn.net/?f=P%28%5Ctext%7Bred%7D%29%3D%5Cdfrac3%7B11%7D)
and
![P(\text{blue})=\dfrac5{11}](https://tex.z-dn.net/?f=P%28%5Ctext%7Bblue%7D%29%3D%5Cdfrac5%7B11%7D)
So
![P(\text{red then blue})=\dfrac{15}{121}](https://tex.z-dn.net/?f=P%28%5Ctext%7Bred%20then%20blue%7D%29%3D%5Cdfrac%7B15%7D%7B121%7D)
1 3/4 hours of work equates to $18.375 so $18.38.
2 1/3 hours of work equates to $24.50.
1 5/12 hours of work equates to $14.875 so $14.88
Add all values $18.38+$24.50+$14.88 = $57.76
Doug has a total amount of earnings which = $57.76, good luck!
