Since there are 100 cents in a dollar, routing to the nearest cent would be rounding to the nearest hundredth. In order to do that you would solve to the thousandths place the use that number to round up or down to the nearest hundredth.
For example:
If a dozen roses cost $12.35, how much does each rose cost?
12.35 ÷ 12 = 1.029
The 9 is in the thousandths place. If it is 5 or higher we round the hundredths place up, so our answer is each rose costs 1 dollar and 3 cents ($1.03)
It would be 25% since the third quartile should be the number in the middle of the second half of a data set. which means it is 75% of the way through.
Numerators: 8 and 7 = 56
Denominaters; 7 and 4 =28
Final answer 56/28 or 2
Using <span>Descartes' rule of signs.
There are 4 changes of signs of coefficients:
+ to - (+x^6-x^5)
- to + (-x^4+4x^3)
+ to - (+4x^3-12x^2)
- to + (-12x^2+12)
Therefore, there are 4,2 or 0 positive roots </span><span><span>at most</span>. So it must be the third answer.
</span>
4x^2-16x+12 is the answer.
