Answer: A
a quadrilateral with all four angles right
Step-by-step explanation:
A quadrilateral is a rectangle if a quadrilateral has all four angles right,
a parallelogram with congruent sides
a quadrilateral with diagonals that are congruent and bisect each other
a quadrilateral with all congruent angles. Because a rectangle possesses 2 pairs of parallel sides, 4 right angles at 90°. It has opposite sides which
are parallel and congruent. And all its angles are congruent.
But a quadrilateral with all four angles right is a description that does NOT guarantee that a quadrilateral is a rectangle. Because this description is also applicable to a square.

Answer:
Not independent
Step-by-step explanation:
This problem involves independence criteria for conditional probabilities.
The two events will be independent if P(A/B)=P(A) or P(B/A)=P(B)
Let us assumes that event A is for student attending private college and B is for student graduating in four years.
So we are given the following probabilities
P(A)=0.20
P(B)=0.55
P(B/A)=0.79
As we can see that P(B/A)≠P(B) so the events A and B are not independent.
So based on the above results we can say that "attending a private college or university" is not independent of "graduating in four years". Thus the two events "attending a private college or university" and "graduating in four years" are dependent.

Use the slope formula and equal it to -3. Solve for x.
