Greeley [361]
Answer is 1.1% chance:
standard deck of cards has 52 cards
jack, queen, and king are face cards, and there are four suits, so in total there are  7 face cards in the deck. There are 4 seven cards in the deck. The probability that the first card is a seven is 0.076923077--> 7.7%, then there are 7 face cards so 7/51 chance 0.137254902--> 13.7% (but that is after 7.7% of 100% has already happened, so we are looking at 13.7% chance of 7.7% chance of 100% cards. Multiply both numbers and you get 0.010558069--> 1.1% chance

Find the missing factor x^2-11x+18=(x-2)( )
tia_tia [17]
I'd use synthetic div. here, with 2 as my divisor:

      ________________
2   /   1    -11    18
                  2   -18
     ----------------------------
         1     -9      0

Note that the coefficients of the missing factor are given here and are 1 and -9.  Thus, (x-9) is the missing factor.

likoan [24]
We can split it up into a net
actually, here is a hack

notice that indented side?
we can take the plane and push it so it makes 4 sides, neat

ok, so we now just have 4 normal sides and 2 L shapes

L shape can be cut into 2 rectangles
5 by 5 and 5 by 10 so total of 75 is the L
2 L's so
2*75=150

the sides
4 of them
they all are 10 by 3
10*3*4=120

toatl is 150+120=270

answer is A
