B. what is the probability that carol, the 44-year-old you're considering for a 20-year policy,
lives to be 64 years old? note that this is a conditional probability. another way of saying this is,
"what is the probability that carol turns 64 years old given that she turns 44 years old? " carol is
a non-hispanic black female, so look in table 18.

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".

2x^2+5x+17

your welcome. : )
