Answer:
The answer is the one at the bottom because the others don't make sense
Step-by-step explanation:
The answer 19 because, 19+8=27, then 27 divided by 9 is equal to 3. If you need to know how I got 19 just let me know!
Take out the GCF of 5.
5(5c - 1)
Begin by computing the number of all the possibilities:
It is given by the following formula:
Computing the number of favorable cases:
Exactly one pair of socks with the same color means either one magenta pair,
or one cyan pair, or one black pair or one white pair:
Number of possibilities with one magenta pair means"a magenta pair plus two socks with different colors from three possibilities" means 3 possibilities.
Same computation for the other colors.
Adding we get:
By definition, the probability of an event is the number of favorable cases over the number of possible cases:
The probability is
Answer:
a = 3
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
a² + 8² = ( )²
a² + 64 = 73 ( subtract 64 from both sides )
a² = 9 ( take the square root of both sides )
a = = 3
