Presumably, whatever is drawn from Urn I is independent of what is drawn from Urn II. This means

We have


so the probability of drawing red balls from both urns is 
Answer:
B. 
Step-by-step explanation:
The right triangle altitude theorem states that the altitude of a right angled triangles formed on the hypotenuse is equal to the geometric mean of the 2 line segments it creates.
This can be represented as:

Where,
h = the length of the altitude,
x and y are the lengths of the 2 segments formed.
Therefore, the length of the altitude = 



C and make sure next time make the pic look cleaer
5000 lbs. 1 Tons equals 2000 lbs. So you multiply 2000 by 2.5.
Answer
The missing length is 10
Step-by-step explanation:
Represent the missing length with x
The sides of the given shape are directly proportional.
Mathematically:
(15 + x) to (12 + 8) and x to 7
Represent as a ratio:
