8 0

Answer:

Option 1

Step-by-step explanation:

You can tell if a function is even if $f(-x)=f(x)$ :

$f(x)=x^2-x+8$

$f(-x)=(-x)^2-(-x)+8$

$f(-x)=x^2+x+8$

Since $f(-x)\neq f(x)$ , the function is not even. Therefore, option 1 is the best option.

If a 4 sided figure has 360°...for each side we add, we add 180°.

you have a 7 sided figure (360° + 3(180°) = 900°)

adding up your angles (781) and subtract it from 900 =

x = 119°

The z score is a score used to determine the number of standard deviations by which the raw score is above or below the mean, it is given by the equation:

$z=\frac{x-\mu}{\sigma} \\\\\mu=mean, \sigma=standard\ deviation,x=raw\ score\\\\for\ a\ sample\ n:\\\\z=\frac{x-\mu}{\sigma/\sqrt{n} }$
