I the equation 3x^2+6x=12, the value of c is?

ozzi

Answer:

c = -12

Step-by-step explanation:

Quadratic Standard Form: ax² + bx + c

Step 1: Write equation

3x² + 6x = 12

Step 2: Subtract 12 on both sides

3x² + 6x - 12 = 0

Here, we have the standard form of the quadratic. We see that our c = -12

What is the standard deviation of the following data set rounded to the nearest tenth?

tamaranim1 [39]

$Formula\ for\ standard\ deviation\ :\\\\
x=\sqrt{y^2}\\
y-variance\\\\
y^2=\frac{(a_1-a)^2+(a_2-a)^2...+(a_n-a)^2}{n}\\
n-amount\ of\ numbers\\
a-mean\\\
a=\frac{11+5+12+8+5+12+10}{7} =\frac{63}{7}=9\\\\
y^2=\frac{(11-9)^2+(5-9)^2+(12-9)^2+(8-9)^2+(5-9)^2(12-9)^2+(10-9)^2}{7}
\\y^2=\frac{(2)^2+(-4)^2+(3)^2+(-1)^2+(-4)^2+(3)^2+1^2}{7}=\\ \frac{4+16+9+1+16+9+1}{7}=\frac{56}{7}=8\\\\
x=\sqrt8=2\sqrt2
