Short answer No.
Explanation
Suppose you have a sample of coins that have the date of production on them. They go from 1990 to 2000 inclusive. There are 100 coins in each year. That means there are 1100 coins because there are 11 years. Now you pick out 10 coins without replacement. Let's say all of them are from 1999. Then the mean is 1999.
If you start again and pick out 10 and get 3 years
4 from 2000
2 from 1995
4 from 1992
Whatever the mean is, it is not 1999. The mean of the second batch is 1995.8!
The product of the two is 0, so one of them have to equal 0 as any number multiplied by 0 is 0.
First solution: x - 4 = 0
If x - 4 = 0, then x = 4. So the first solution for <em>x </em>is 4.
Second Solution: -5x + 1 = 0
Solving...
-5x + 1 = 0
-5x = -1
x = -1/-5
x = 1/5 or 0.2
So x = 0.2 and 4
{ y ≥ 2x + 1; y > -2x - 3 } Unbound

Alrighty, so, you know how young children often believe that a taller container will have a greater volume than a shorter container? Even after seeing that both containers hold the same amount, some children will still think the taller container holds more. It may take measuring the water a few times before they get it.
<em>If it overflows, the first container is bigger, or is able to hold more water. If all of the water from the first container can be poured into the second container without completely filling it, then the second container holds more water.</em>
The tallest container holds the most liquid. Identical containers can have a different capacity.
