The probability that a student participates in both sports and music is 108/1376
<u>Explanation:</u>
Let x be the number of students participating in both sports and music
According to the question:
P(A or B) = P(A) + P(B) - P(A and B)
P(sports or music) = P(sports) + P(music) - P(sports and music)
![\frac{974}{1376} = \frac{649}{1376} + \frac{433}{1376} - \frac{x}{1376} \\\\974 = 1082 - x\\\\x = 108](https://tex.z-dn.net/?f=%5Cfrac%7B974%7D%7B1376%7D%20%3D%20%5Cfrac%7B649%7D%7B1376%7D%20%2B%20%5Cfrac%7B433%7D%7B1376%7D%20-%20%5Cfrac%7Bx%7D%7B1376%7D%20%5C%5C%5C%5C974%20%3D%201082%20-%20x%5C%5C%5C%5Cx%20%3D%20108)
P(sports and music) = ![\frac{108}{1376}](https://tex.z-dn.net/?f=%5Cfrac%7B108%7D%7B1376%7D)
Therefore, the probability that a student participates in both sports and music is 108/1376
Answer:
The diagonal is 421.
Step-by-step explanation:
This is a difficult question. To find the diagonal, you need to find the base and the height of the square. After that, you need to make it a triangle, by using this equation;
(A being area, B being base, and H being height) then find the length of the hypotenuse of the triangle, which I will do for you.
The B and H = 416. Plug it into the equation now;
Now that you have done that, we know that the area of our new triangle is 86,528.
The diagonal is: ![421](https://tex.z-dn.net/?f=421)
