Answer:
Step-by-step explanation:
Let 
represent students playing basketball, 
represent students playing baseball.
Then, 
, 
Let 
be the total number of students. So, 
.
Now,
3 students play neither of the sport. So, students playing either of the two sports is given as:
∴ 
From the probability addition theorem,
Where, 
is the probability that a student chosen randomly from the class plays both basketball and baseball.
Plug in all the values and solve for . This gives,
Therefore, the probability that a student chosen randomly from the class plays both basketball and baseball is

Step-by-step explanation: How do you find the 3rd angle of a triangle?
Image result for im not sure on how to do this If one angle of a triangle is 30° more than twice another angle, and the third angle is equal to the sum of the first two angles, find the measure of each angle.
The three angles of any triangle add up to 180 degrees. Since you know two angles (35 and 40), add them together, then subtract the total from 180 to determine the degree of the third angle.
Answer:
To find the scale factor, locate two corresponding sides, one on each figure. Write the ratio of one length to the other to find the scale factor from one figure to the other. In this example, the scale factor from the blue figure to the red figure is 1.6 : 3.2, or 1 : 2.
Step-by-step explanation:
let g(x) = x^2+2
let f(x) = 9/x
f(g(x)) is therefore equal to f(x^2 + 2) which is equal to 9/(x^2+2).
