A rectangle has a length that is equal to 4 less than twice the width. The function for the perimeter depending on the width can
be expressed with the function f(w) = 6w – 8, where w is the width of the rectangle in centimeters. Which statement describes how the reasonable domain compares to the mathematical domain?
Both the mathematical and reasonable domains include only positive real numbers.
Both the mathematical and reasonable domains include only positive whole numbers.
The mathematical domain includes all real numbers, while the reasonable domain includes only real numbers greater than 2.
The mathematical domain includes all real numbers, while the reasonable domain includes only whole numbers greater than 2.
The mathematical domain includes all real numbers, while the reasonable domain includes only real numbers greater than 2
Step-by-step explanation:
In the real world, length and width only make sense when they are positive. For that to be the case, the width must be greater than 2. There is nothing in the description that restricts the values to integers.
The card you draw is just as likely to be the ace of spades as that can be selected from any other from 51 cards.So the chance of it being the ace of spades is 1/52
