Suppose that y varies directly with x and y=10 when x=-20. What is y when x =15?
USPshnik [31]

Answer:

15/2

Step-by-step explanation:

You want to first find the connection between the first statement, y=10 and x=20. The connection is that Y is X divided by 2. Then you want to just do the same equation to the y and keep it a fraction. (Hint. a fraction is the same as what you do to divide, its just the equation before you find your answer.) so your answer is 15/2.

Hope its right, and i hope this helped.

In a group of 28 students, 12 study both Art and Biology.
MAVERICK [17]

Answer:

100%

Step-by-step explanation:

Use conditional probability:

P(B | A) = P(B and A) / P(A)

P(B | A) = (12/28) / P(A)

We need to find the probability that a student studies art.

P(A or B) = P(A) + P(B) − P(A and B)

24/28 = P(A) + (12+12)/28 − 12/28

P(A) = 12/28

P(B | A) = (12/28) / (12/28)

P(B | A) = 1

What this means is that all of the students who study art also study biology.

MArishka [77]

Answer:

6√2

Step-by-step explanation:

So the diagonal of a square is equal to √2 times the length of the side of the square. Working backwards that would mean: 12/√2 = side of square

this means that the side of the square is 6√2

The side of the square is also the diameter of the circle.

I'm not sure this was the type of formula you're looking for but I hope it helped!
