Answer:
6.67 Miles Per Hour
Step-by-step explanation:
Step 1
State the formula for the probability of an event
![Pr(event)=\frac{required\text{ number of events }}{Total\text{ number of events}}](https://tex.z-dn.net/?f=Pr%28event%29%3D%5Cfrac%7Brequired%5Ctext%7B%20number%20of%20events%20%7D%7D%7BTotal%5Ctext%7B%20number%20of%20events%7D%7D)
The required number of event= The students with 2 or more pets= 15+7+3+2+0 = 27
Total number of events=4+11+15+7+3+2+0=42
Step 2
Estimate the probability that a randomly selected student from this class has 2 or more pets.
![Pr(Students\text{ with }2\text{ pets or more})\frac{27}{42}\approx0.64](https://tex.z-dn.net/?f=Pr%28Students%5Ctext%7B%20with%20%7D2%5Ctext%7B%20pets%20or%20more%7D%29%5Cfrac%7B27%7D%7B42%7D%5Capprox0.64)
Answer; Option C 27/42 or approximately 0.64
X + y = 8
Replace y as y = y Insert x back into the original
x + x - 2 = 8 5 + y = 8
2x - 2 = 8 - 5 - 5
+ 2 + 2 y = 3
2x = 10 (5, 3)

x = 5
55 degrees. If you add the other three angles together you get 305. Considering that a circle is 360 degrees, you would subtract those two and get 55.
