Answer:
The end points of line segment are:
![(x_1,y_1) = (5,4)\\(x_2,y_2) = (-4,-3)](https://tex.z-dn.net/?f=%28x_1%2Cy_1%29%20%3D%20%285%2C4%29%5C%5C%28x_2%2Cy_2%29%20%20%3D%20%28-4%2C-3%29)
Using distance formula,
Distance =
= ![\sqrt{(-4-5)^{2}+(-3-4)^{2}} = \sqrt{(-9)^{2}+(-7)^{2}} = \sqrt{81+49}=\sqrt{130} units](https://tex.z-dn.net/?f=%5Csqrt%7B%28-4-5%29%5E%7B2%7D%2B%28-3-4%29%5E%7B2%7D%7D%20%3D%20%5Csqrt%7B%28-9%29%5E%7B2%7D%2B%28-7%29%5E%7B2%7D%7D%20%3D%20%5Csqrt%7B81%2B49%7D%3D%5Csqrt%7B130%7D%20units)
You would travel 73.333334ft per second because 50 miles/hour would make 73.333333repete foot/second.
Step-by-step explanation:
Total marbles = 9 + 4 + 3 + 2 = 18
Probability of both red marbles = 3 / 18 = 1/6
