Answer:
r=1
Step-by-step explanation:
First we need to know the length of each side of the triangle, so we use the formula of the vector modulus:
By doing so, we find:
With this we know that the triangle is not right, but, we assume the longest side as the hypotenuse of the problem.
As we have two equal sides, we know that the line between point |AB| and the center of the hypotenuse is perpendicular, therefore, we can calculate it using Pythagoras theorem:

Answer:
Step-by-step explanation:
Lets keep the variable terms in L.H.S. and the constant terms in R.H.S.
Lets divide 43 on both the sides.
The probability of drawing the Red 4 is 1 in 10. So, the chances of getting it would be 1/10.The probability is also the same for drawing the Blue 4, so it would be 1/10 also.
The probability assignment for this problem is the classical method which means that experimental outcomes are equally likely. So, just multiply the probability of the first event to the second event.
= 1/10 * 1/10 = 1/100
The probability of getting the blue and red four is 1/100 or 0.01.
