Step-by-step explanation:
So, you have to get angle under 130° angle:
180°-130°= 50°
And you get X
x=180°-(113°+50°)
x=180°- 163°
x=17°
I'm not sure how to give you solid proof, like an equation or something, but you can see that out of the four coordinates, two of them have the y-value of 4 and two of them have the y-value of 2. Also, there is 1.5 in between each x-value that is paired with the same y-value... if that makes sense. So for (0.5, 2) and (3, 2), there is 1.5 in between 0.5 and 3. I hope this helps! Sorry it's a bit of a weird answer

<u>The correct answer is B).</u>
Answer:
B. 0.4
Step-by-step explanation:
Use the definition of the probability
![Pr=\dfrac{\text{Number of all favorable outcomes}}{\text{Number of all possible outcomes}}](https://tex.z-dn.net/?f=Pr%3D%5Cdfrac%7B%5Ctext%7BNumber%20of%20all%20favorable%20outcomes%7D%7D%7B%5Ctext%7BNumber%20of%20all%20possible%20outcomes%7D%7D)
You have to find the probability that a randomly selected reference book is hard cover. Hence, from the table
- Number of all possible outcomes = Number of Reference books = 25
- Number of all favorable outcomes = Number of Hardcover Reference books = 10
So, the probability is
![Pr=\dfrac{10}{25}=\dfrac{40}{100}=0.4](https://tex.z-dn.net/?f=Pr%3D%5Cdfrac%7B10%7D%7B25%7D%3D%5Cdfrac%7B40%7D%7B100%7D%3D0.4)
