You would round it UP - to 20.
5x1 = 5 5x2 = 10 5x3 = 15 5x4 = 20

To round 19.826 to the nearest whole number, we look at the digit in the tenths place, which is 8. Since 8 is greater than or equal to 5, we round up the whole number to 20. Therefore, 19.826 rounded to the nearest whole number is 20.

x2+9x+18 find factors of 18 that add up to 9, in this case 6&3 (x+6)(x+3)
You can do this by finding two numbers whose sum is -9, and whose multiple is 20. Because their product is positive and their sum is negative, you know they'll both be negative numbers. So first find all of the factors of 20: 2 * 10 = 20 5 * 4 = 20 Now find which of those adds up to 9: 2 + 10 = 12 5 + 4 = 9 So we know five and four are the numbers we want. Remember though that they'll both be negative. So our end result is: x2 - 9x + 20 = (x - 4)(x - 5)
z = (80 - 100)/20 = -20/20 = -1 Look up a table of z-scores: Probability = 15.87%
Since your decimal is higher than .500 you round up to the next whole number, in this case it is 20.
I had the whole project set up before gluing it together when I knocked the table and it collapsed; when I reconstruct it, I will glue it as I assemble it.
X^2 - 9X + 14 = 0 what two factors of 14 add up to - 9 ? (X - 2)(X - 7) so, X = 2 X = 7
To simplify x3-9x, you factor out the x, leaving you with x(x2-9). You can then take the square root of both numbers and end up with x(x+3)(x-3).
