A conjecture and the flowchart proof used to prove the conjecture are shown.Drag an expression or phrase to each box to complete
Mice21 [21]

Solution: The solution is shown is below figure.

Explanation:

From the given information JKLM is a parallelogram and \underset{LN}{\rightarrow} bisects \angle KLP. So Blank 1 is filled by Given and blank 2 is filled by \underset{LN}{\rightarrow} bisects \angle KLP.

Parallelogram is a quadrilateral  whose opposite sides are equal or parallel. Since it is given that JKLM is a parallelogram, therefore the side JM is parallel to the side KL. So blank 3 filled by Definition of parallelogram.

If a line bisects an angle it is means it divides the angle in two equal parts. Since \underset{LN}{\rightarrow} bisects \angle KLP, therefore \angle 2\cong \angle 3. Hence the blank 4 is filled by Definition of bisect.

The transitive property of congruence states that if \angle 1\cong \angle 2 and \angle 2\cong \angle 3, then \angle 1\cong \angle 3. Thus, the blank 5 is filled by Transitive Property of Congruence.

Sally has two coins. The first coin is a fair coin and the second coin is biased. The biased coin comes up heads with probabilit
coldgirl [10]

Answer:

50%

Step-by-step explanation:

''What is the probability that she selected the biased coin?”

When we have n possible outcomes of an event and all of them have the same probability of appearance, then in theory each possibility has a probability 1/n of being the result of the event.

In this case the event is choosing randomly a coin out of 2, so no matter what the biased coin is or the results we get when we toss it, the probability of choosing the biased coin is ½ = 0.5 or 50%.
