We are given the coordinates of a polygon that are (0,0), (a,0), (a,a), (0,a). we can project these coordinates in a plot and see that there are four sides of the polygon. The sides of the polygon re equal and perpendicular to each other. Hence the polygon is a square

Answer:

c) Events A and B are independent events.

The outcomes of events A and B are dependent on each other.

P(A and B)=P(A)•P(B)

Step-by-step explanation:

Given:

Total number, n = 52

Each suit contains 13 cards: 2 to 10, a jack, a queen, a king, and an ace.

Since there are 4 suits, it means the number of each card is four.

P(A) = event of picking a king

P(B) = event of picking a 3

Therefore the probability of picking a king = P(A) = \frac{4}{52}

Probability of picking a 3 = P(B) = \frac{4}{52}

Since only a card is picked, the probability a king is picked after picking a 3 is 0.

i.e P(A|B) = 0 ≠ P(A) = \frac{4}{52}

option A is wrong

The probability a 3 is picked after picking a king is 0.

i.e P(B | A) = 0 ≠ P(B) = \frac{4}{52}

option B is wrong

Events A and B are independent events.

The outcomes of events A and B are dependent on each other.

P(A and B)=P(A)•P(B)

Option C is correct.

Among all the rectangles whose perimeters are 100 feet, find the dimensions of the one with the maximum area. explain step by st
kompoz [17]
<span>We let x be the length and y be the width of the rectangle. Then,
 
Perimeter = 2x + 2y
100 = 2x + 2y
50 = x + y
y = 50 - x
 
Area = xy
A = x(50 - x)
A = 50x - x^2
 
We then take the derivative; set it equal to zero:
 
A ' = 50 - 2x
0 = 50 - 2x
2x = 50
x = 25
y = 50 - x
y = 50 - 25
y = 25
 
Therefore, the dimensions are 25 and 25.</span>
