Quadrilateral ABCD has the following vertices:
GenaCL600 [577]

9514 1404 393

Answer:

  yes

Step-by-step explanation:

The figure can be shown to be a parallelogram by showing the sum of endpoints of the diagonals is the same.

  A +C = B +D

  (0, 6) +(0, -4) = (0, 2) = (3, 5) +(-3, -3) . . . . diagonals bisect each other

If the diagonals of a quadrilateral bisect each other, it is a parallelogram. A parallelogram with a right angle is a rectangle. So, ABCD is a rectangle.

_____

<em>Additional comment</em>

The midpoint of each diagonal is half the sum of the end point coordinates. That is, the midpoints are (0, 2)/2 = (0, 1). Since calculation of the midpoints requires both sums be divided by 2, we can tell the midpoints are the same if the sums are the same.

The closing price of Schnur Sporting Goods Inc. common stock is uniformly distributed between $16 and $30 per share.
serg [7]

Answer:

a) 0.3571 = 35.71% probability that the stock price will be more than $25.

b) 0.1429 = 14.29% probability that the stock price will be less than or equal to $18.

Step-by-step explanation:

Uniform probability distribution:

An uniform distribution has two bounds, a and b.

The probability of finding a value of at lower than x is:

P(X < x) = \frac{x - a}{b - a}

The probability of finding a value between c and d is:

P(c \leq X \leq d) = \frac{d - c}{b - a}

The probability of finding a value above x is:

P(X > x) = \frac{b - x}{b - a}

Uniformly distributed between $16 and $30 per share.

This means that a = 16, b = 30

a) More than $25?

P(X > x) = \frac{30 - 25}{30 - 16} = 0.3571

0.3571 = 35.71% probability that the stock price will be more than $25.

b) Less than or equal to $18?

P(X < 18) = \frac{18 - 16}{30 - 16} = 0.1429

0.1429 = 14.29% probability that the stock price will be less than or equal to $18.
