Answer:
The length and width of the rectangle are 20 inches and 17 inches .
Step-by-step explanation:
Formula
Area of a rectangle = Length × Breadth
As given
The width of a rectangle is 3 inches less than its length. The area of the rectangle is 340 square inches.
Let us assume that the length is denoted by l.
Thus
Breadth = l - 3
Put in the above formula
340 = l × (l - 3)
340 = l² - 3l
l² - 3l - 340 = 0
l² - 20l + 17l - 340 = 0
l(l-20) + 17 (l-20) = 0
(l - 20) ( l+ 17) = 0
l = 20
l = -17 (This valueof length is neglected because length cannot be negative.)
As l = 20 inches
Breadth = 20 - 3
= 17 inches
Therefore the length and width of the rectangle are 20 inches and 17 inches .
Step-by-step explanation:
Replacement means the probability of each trial is the same (the trials are independent).
For example, let's say you have a standard deck of 52 cards, and you want to find the probability of drawing a queen card twice.
There are 4 queens, so the probability on the first draw is 4/52.
You then replace the queen, so there are still 4 queens in the deck. So the probability on the second draw is still 4/52.
The total probability is the product: 4/52 × 4/52 = 1/169
If you didn't replace the queen after the first draw, there would have been 3 queens in the deck, and the probability on the second draw would have been 3/52.
