grandymaker [24]

the way you have laid this question out is strange but im assuming you want me to find the mean, range, medium and mode of the numbers provided?

<h2>Answer:</h2>

median=order them and find the middle= <u><em>6</em></u>

mean=add them all up and divide by the amount of numbers=(6+13+7+9+5+3+2+5+4+10+12)/11=<em><u>6.9</u></em>

range= the difference between the smallest and largest number=13-2=<u><em>11</em></u>

mode= the one that appears the most= <em><u>5</u></em>

Please someone help me, I will give you brainliest <br><br> Factor the expression: y^2 + y + 1/4
Firdavs [7]

Answer:

y² + y + \frac{1}{4} = (y + \frac{1}{2})²

Step-by-step explanation:

In most cases, we can factor a polynomial, or quadratic, by looking at the factors of the last term.  In this case, the last term is \frac{1}{4}.  When we factor a polynomial, we are looking for two expressions that when multiplied together using FOIL (forward-outside-inside-last) will give us the polynomial.  For example: (a + b)(a + b) or (a+ b)².

In order to get y² + y + \frac{1}{4}, we are looking for a 'c' value that will add up to '1' which is our 'b' value (ay² + by + c).

Since \frac{1}{2}*\frac{1}{2}=\frac{1}{4}and\frac{1}{2}+\frac{1}{2}=1

Then, we can use \frac{1}{2} as our factor for both expressions.  Putting this together we get:  (y + \frac{1}{2})(y + \frac{1}{2}) or (y + \frac{1}{2})²
