At Venn diagram there are 4 parts (20 pieces):
1. Colored only in blue - quadrilaterals with four equal side lengths (3 pieces);
2. Colored only in orange - quadrilaterals with four right angles (6 pieces);
3. Colored in both blue and orange - quadrilaterals with four right angles and with four equal side lengths (2 pieces);
4. Colored in white - quadrilaterals withoutprevious two properties (9 pieces).
Consider events:
A - a randomly chosen quadrilateral has four right angles;
B - a randomly chosen quadrilateral has four equal side lengths;
Use formula
to find the probability that a randomly selected quadrilateral with 4 right angles also has four equal side lengths:

Answer: Pr=0.25
The typical form of the slope intercept equation would be:
Y = mX + B
Where b is the y intercept, thus in thus case the y intercept would be 65 = (0,65).
There’s a 50 cents difference woahhhh
A straight angle is 180 degrees. if you bisect it (cut it in half), you'll end up with two 90 degree angles, which are called right angles.
180a^3+900a^3+4a-5
