(x - 4)(x^2 + 3x + 2) =
x(x^2 + 3x + 2) - 4(x^2 + 3x + 2) =
x^3 + 3x^2 + 2x - 4x^2 - 12x - 8 =
x^3 -x^2 - 10x - 8
Answer:
JK = 20
Step-by-step explanation:
Angle Bisector Theorem: an angle bisector of a triangle divide the opposite side into two segments that are proportional to the other two sides of the triangle
LK / JK = LM / JM
(45 - JK) / JK = 75 / 60 = 5 / 4
5 JK = 4 (45 - JK)
5 JK = 180 - 4 JK
9 JK = 180
JK = 20
Answer:
22.20
Step-by-step explanation:
25 × .80 ×1.10=22.20
Answer:
a.) Expected value on earning points= 21
b.) Expected value on earnings for composites = -1
Step-by-step explanation:
Expected value = [(6*1 + 6*2 + 6*3 + 6*4 + 6*5 + 6*6 ) ]* (1/6) = 6*(7)/2 = 21
b.) how many composite numbers from 1 to 6
4 and 6
so...
Expected Value of earning = [(-6*1 - 6*2 - 6*3 + 6*4 - 6*5 + 6*6 ) ]* (1/6) =
-1 - 2 - 3 + 4 - 5 + 6 = -1
