Answer:
The solution to the quadratic equation:
Step-by-step explanation:
Given the equation
6x - 0.2x · x = 0
Factor out common term -x
-x (0.2x - 6) = 0
Using the zero factor principle
if ab=0, then a=0 or b=0 (or both a=0 and b=0)
solving
Multiply both sides by 10
Refine
Add 60 to both sides
Simplify
Divide both sides by 2
Simplify
Thus, the solution to the quadratic equation:
144 cannot be a factor of 72 since it is bigger than 72
Answer:
(52/52)(48/51)(44/20)(40/59)(36/48)
Step-by-step explanation:
For the first card, what is the chance of getting a unique value? Well, you don't have any yet so it's 100% or 52/52.
Now for the second draw, what is the probability of not getting a repeat? Well, 52 cards total but there are four copies of every value, one for each suit. The deck now has 51 cards and 48 are not copies, so that's 48/51.
Similarly for the third draw there are now 50 cards total and 44 are not going to be repeats if the last two were not.
You can keep going like this and you get (52/52)(48/51)(44/20)(40/59)(36/48). Hopefully this made sense.
