If you follow a similar approach by drawing a line through point C that is perpendicular to and using the associated defects for
∠A or ∠B instead of ∠C, what are the resulting equations? (Do not go through the complete derivation again, just think about the result you came up with in question 9 and what similar formulas for ∠A or ∠B would look like.)

Answer:
Step-by-step explanation:
Vertices of the given quadrilateral are A(-4, 3), B(2, -1), C(2, -5) and D(-4, -1)
Since, slope of a line passing through two points and
is given by,
Slope =
Slope of AB =
=
Slope of AD =
= Not defined (Parallel to y-axis)
Slope of DC =
=
Slope of BC =
= Not defined (Parallel to y-axis)
Slope of AB = slope of DC =
Slope of BC = slope of AD = Not defined (parallel to y-axis)
As per property of a parallelogram,
"Opposite sides of a parallelogram are parallel and equal in measure"
Therefore, ABCD is a parallelogram.
Answer: Our required probability is 0.278.
Step-by-step explanation:
Since we have given that
Probability that a player has a batting average = 0.260
Probability of success = 0.260
Probability of failure = 1-0.260 = 0.74
Number of times at bat = 4
Probability that the player will get two or more hits in his next four times at bat is given by
Hence, our required probability is 0.278.
