There are two Geometry classes at a high school. Two students are being picked to attend a special math competition, one student from each class. If there are 20 students in one class and 26 students in the other, find the probability of being picked to attend the competition.

1/23

Step-by-step explanation:

First you find the individual probabilities!

20 Class = 1/20 probability

26 Class =1/26 probability

Since you are trying to find the probability for both probabilities together, you add your probabilties together.

1/20 + 1/26 = 2/46

Next, we need to reduce this fraction.

To do this, lets divide this by 2.

2 ÷ 2 = 1 and 46 ÷ 2 = 23

This gives us the answer of 1/23

3,750 deer

step-by-step explanation:

1,500 is 15 times larger than 100

lets make 250 15 times larger.

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
