HELP (BRAINLIEST ANSWER IF RIGHT)...In a certain Algebra 2 class of 30 students, 7 of them play basketball and 11 of them play baseball. There are 5 students who play both sports. What is the probability that a student chosen randomly from the class plays basketball or baseball?

13 / 30

Step-by-step explanation:

The probability an be represented by the number of desirable outcomes over the total outcomes. We know the total is 30 since there are 30 students to be chose from. Now, we need to find the number of students who play basketball and baseball. We can add the two values we are given:

7 + 11 = 18 students

BUT we are over-counting the students who play both. We need to subtract those 5 students, since the are counted twice, and that way, they will only be counted once:

18 - 5 = 13 students

Using the formula for probability at the top, we get:

13 / 30

for the friend request.

when a figure, such as triangle (xyz) is reflected over the line y = x to create x'y'z' the x-coordinates and y-coordinates of the original image (pre-image) will be reversed for the image. (e.g., (x, y) > (y, x)) this means that the pre-image position of the x- and y-coordinates switch places which in turn provides a mirror like image of the original xyz.  

i notice that when i draw a line segment from x to x', that the points are parallel from each other -- they are exactly across from each other and do not intersect with any other points.  

yes, think i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line because of the essence of reflections. because it is a mirror image, each point was effected the same way which leads me to conclude that they same would apply to y and y'.
