To find median . . . list the number in order from least to greatest

10 , 11, 12, 12 13, 15

Then cross of a number from each side until you get to the middle number or middle 2 numbers.
IF there are 2 numbers add them together and divide by 2

12 + 12 = 24
24 / 2 = 12

Your median is 12

To find mean (this is the same as average) add all the numbers to get a total.

10 + 11 + 12 + 12 + 13 + 15 = 73

Then count the number of items added . . .6

Take the total and divide by the items counted

73 / 6 = 12.1666

Your directions say to round to the nearest tenth place.   

12.166 = 12.2

Divide x^3-3x^2-10x+24 by x-1
lesya [120]

Answer:

x^2 - 2x - 12 with remainder 12

Step-by-step explanation:

Synthetic division is the fastest way in which to carry out this division.

The divisor (x - 1) from long division corresponds to the divisor 1 in synthetic division.  Setting up synthetic division, we get:

1     /      1     -3     -10     24

                     1      -2     -12

      --------------------------------

             1      -2     -12      12

The first three digits {1, -2, -12} are the coefficients of the quotient, and 12 represents the remainder:

The quotient is 1x^2 - 2x - 12 and the remainder is 12.

How do I graph the inequality of this equation.<br><br> y &gt; x + 2
ZanzabumX [31]
-- For just a minute, make it an Equality . . . y = x + 2 .

-- Graph the Equality.  That graph is a straight line.

-- The INequality says that 'y' is LESS than x+2,
and THAT's everything UNDER the line.
(But not the points on the line itself.)
