Answer:

$f(x) = x^2 -10x +22$

And we want to find the domain. And that represent the possible values for x. Since we have a quadratic function we have that the domain would be all the reals, and we can write:

$D= [x \in R]$

Where D represent the domain and R the set of the real numbers.

Step-by-step explanation:

For this case we have the following function:

$f(x) = x^2 -10x +22$

And we want to find the domain. And that represent the possible values for x. Since we have a quadratic function we have that the domain would be all the reals, and we can write:

$D= [x \in R]$

Where D represent the domain and R the set of the real numbers.

Use the diagram to answer the following questions.125°Lx2X+10NmZNPMdegreesmZLPMdegrees

lutik1710 [3]

For the angle MPN we know that is oposite to the angle QPL so the will be equal so:

$\angle MPN=125º$

Now with the value of MPN we can made an equation for x so:

$125=2x+10$

and we solve for x

$\begin{gathered} 125-10=2x \\ \frac{115}{2}=x \\ 57.5=x \end{gathered}$

and the angle LPM will be the complementari angle of 125 so:

$\begin{gathered} \angle LPM=180-125 \\ \angle LPM=55º \end{gathered}$

An insurance company sells one-fourth as many preferred policies as standard policies and one-fourth as many ultra-preferred pol

Arisa [49]

Answer:

4.7619%

Step-by-step explanation:

Let's suppose the insurance company sells 16 standard policies.

For every 16 standard policies sold, the company sells 1/4 x 16, or 4, preferred policies.

For every 4 preferred policies sold, the company sells 1/4 x 4, or 1, ultra-preferred policy.

Therefore, for every ultra-preferred policy sold, the company sells:

16+4+1=21 total policies

So the probability of any 1 random policy selected being ultra-preferred is 1/21, or 4.7619% ....................
