In your top dresser drawer are 6 blue socks and 10 grey socks, unpaired and mixed up. One dark morning you pull two socks from t

pishuonlain [190]

Answer:

D) 0.500

Step-by-step explanation:

Blue Socks = 6

Grey socks = 10

Probabilities to find :

Since there are a total of 16 socks, the probability of both socks being blue is

Probability(blue) = $(\frac{6}{16} ) \frac{5}{15} =\frac{30}{240} =\frac{1}{8}$

The probability of both being grey is

Probability(grey) = $(\frac{10}{16} ) \frac{9}{15} =\frac{90}{240} =\frac{3}{8}$

(Note: After 1 sock is picked , next sock drawn would have a different probability as 1 sock is already picked so it would be 1 minus the total socks available of that color)

The probability two socks match:

Probability(blue) + Probability(grey) = $\frac{1}{8}$ + $\frac{3}{8}$ = $\frac{4}{8}$ = $\frac{1}{2}$ = 0.500

How to factor this expression: x^2-9?

Lena [83]

Answer:

(x+3)(x-3)

Step-by-step explanation:

rewrite "9" as 3^2

so it is x^2-3^2

You use the difference of squares: a^2-b^2=(a+b)(a-b)

apply it: (x+3)(x-3)
