Foil method:
FOIL stands for
first-multiply the first term in each set of parenthesis
outer-multiply the outer term in each of the perenthesis
inner- multiply the inner term in each of the parenthesis
last- multiply the last term in each of the parenthesis
(3x+8)(x+1)
(3x*x)=3x^2
(3x*1)=3x
8*x=8x
8*1=8
thus we shall have:
3x^2+3x+8x+8
=3x^2+11x+8
Distributive property:
(3x+8)(x+1)
3x(x+1)+8(x+1)
3x^2+3x+8x+8
=3x^2+11x+8
Both methods are efficient, it all depends with the users preference
C. The lower quartile (of a box-and-whisker plot) is the median of the lower half of the data.

Answer:
0.2
Step-by-step explanation:
Conditional probability:
P(A | B) = P(A & B) / P(B)
P(striped | red) = P(striped & red) / P(red)
P(striped | red) = 0.05 / 0.25
P(striped | red) = 0.2
80 degrees since the corrisponding angle, A, is also 80 degrees
