Yes it does because in order to find out if a triangle is a right triangle, you can use the Pythagorean theorem.
sqrr 2 squared + sqrr 2 squared= 2 squared
simplify this:
2+2=4
because the equation is correct, this can make a right triangle
Step-by-step explanation:
Since this circle is partial we will divide the area of the whole circle by 2
the area of a circle is expressed by
so insert 14 for the radius.


divide the area by 2

Answer:
.0022
Step-by-step explanation:
Answer:
0.5
Step-by-step explanation:
Let D be the event of selecting a marble with dots.
Let P be the event of selecting a purple marble.
The probability of selecting a marble with dots, P(D)=0.2
The probability of selecting a marble that is both purple and has dots, 
We want to determine the probability of selecting a purple marble given that the marble has dots on it, P(P|D)
By the definition of conditional probability:

The probability of selecting a purple marble given that the marble has dots on it is 0.5.
