How do you find an experimental probability of a simple event

1 answer:

4 0

'Experimental' means that you actually set up the situation, you
ran it several times, and you kept a record of the results.

Example:
You flipped a coin 100 times. It came up Heads 46 times, and
Tails 54 times. The experimental probability of Heads was 46%.

Find f(x)+g(x), given f(x)=x^2-8 and g(x)=-2-x^2<br><br><br> Help please show your work please

swat32

Answer:

$\left(x^{2-8}\right)+\left(-2x^2\right)=\frac{1}{x^6}-2x^2$

Step-by-step explanation:

$\left(x^{2-8}\right)+\left(-2x^2\right)$

$=x^{2-8}-2x^2$

$=x^{-6}-2x^2$

$=\frac{1}{x^6}-2x^2$

|x+18|=1

zepelin [54]

The absolute value, or modulus, of a number is its distance from zero, or essentially its magnitude.

The absolute value produces a positive answer.

We have this definition for the absolute value, taking into account its different values for different signs:

$|x|= \left \{ {{x, \ \ \ x \ \geq \ 0} \atop {-x, \ \ \ x \ \ \textless \ \ 0}} \right.$

Thus, for $|x+18|=1$ , we split the absolute value as such:

$x+18=1$ and $x+18=-1$

We solve each case.

$x=-17$ and $x=-19$

We check these solutions.

$|-17+18|=1\\|1|=1\\1=1$
and
$|-19+18|=1\\|-1|=1\\1=1$
