It's B. 0.4
Step-by-step explanation:
the first probability is 0.6 and 0.6+x=1 so x is 0.4
Answer:
y^3 + 5y + 8
Step-by-step explanation:
Collect like terms
4y^3 - 3y^3 + 2y + 2y + y + 4 + 4
= 1y^3 + 5y + 8 OR y^3 + 5y + 8
If the smaller number is x, then the larger number has to be 20 - x in order for the arithmetic mean to be 10, as their sum must be 20.
If the geometric mean is 8 the product of the numbers has to be 64 and so the larger number is 64/x
Solving 64/x = 20 - x gives the quadratic x^2 -20x +64 = 0 so x = 4 or 16.
The two numbers are 4 and 16.
Answer:
$38.40
Step-by-step explanation:
to get your total you multiply
48 x 20% =9.60
