Answer:
x equals plus or minus square root of 5 minus 1
Step-by-step explanation:
we have
Divide by 2 the coefficient of the x-term
squared the number
Adds both sides
Rewrite as perfect squares
take the square root both sides
therefore
x equals plus or minus square root of 5 minus 1
Equation Form:
w x 2 19
Divide both sides by 2:
w 9.5
So, w must be equal to or greater than 9.5 for this equation to work.
There are ways of drawing a 4-card hand, where
is the so-called binomial coefficient.
There are 13 different card values, of which we want the hand to represent 4 values, so there are ways of meeting this requirement.
For each card value, there are 4 choices of suit, of which we only pick 1, so there are ways of picking a card of any given value. We draw 4 cards from the deck, so there are
possible hands in which each card has a different value.
Then there are total hands in which all 4 cards have distinct values, and the probability of drawing such a hand is
