Answer:

a-\sqrt{b}

Step-by-step explanation:

It's important to know that where roots of a polynomial involves radical roots, it does as conjugates. That is, the roots have the same terms but with a opposite middle sign between.

So, in this case, we have one root a+\sqrt{b}, which involves a root and a positive sign. To complete the conjugate behaviour, the other roots has to have the same terms but with different sign between, that is a-\sqrt{b}

Therefore, the answer that completes the given statement is

a-\sqrt{b}

Which graph represents the solution to the given system ? Y=- 6X - 2Y +2=- 6X
Nonamiya [84]

Answer: The graph is attached.

Step-by-step explanation:

The equation of the line in Slope-Intercept form is:

y=mx+b

Where "m" is the slope and "b" is the y-intercept.

Given the first equation:

y=- 6x - 2

You can identify that:

m=-6\\b=-2

 By definition, the line intersects the x-axis when y=0. Then, subsituting this value into the equation and solving for "x", you get that the x-intercept is:

0=- 6x - 2\\\\2=-6x\\\\x=-\frac{1}{3}\\\\x=-0.333

Now you can graph it.

Solve for "y" from the second equation:

y +2=- 6x\\\\y=-6x-2

 You can identify that:

m=-6\\b=-2

Notice that the slopes and the y-intercepts of the first line and the second line are equal; this means that they are exactly the same line and the System of equations  has<u> Infinitely many solutions.</u>

See the graph attached.

Dario buys applesauce for a family reunion. He needs 23 cups, and he buys them in packs of 6. How many packs does Dario need?
hodyreva [135]
He has to buy 4 packs. If you divide 23 by 6, you get 3.833 but you can’t buy a fraction of a pack so you have to round up and buy 4 packs. Hope this made sense; I can explain further if needed!

A researcher wants to know how professional athletes in her city feel about safety measures. She obtains a list of 952 professio
mojhsa [17]

Answer:

For this case the population represent all the professional athletes in the researcher city and we can assume that the sample size for tis population is N =982 and represent all the individuals of interest for the study and the parameter of interest is the proportion of athletes who believe that the enforcement of safety measures needs to be completely overhauled p.

In order to estimate te parameters of the population the researcher select a sample of 400 professional athletes and just 86 of them returns the questionnaire sent. So then the real sample is the n =86 people who return the info, because the other people are part of the non response rate, and from this sample she found that the proportion of athletes who believe that the enforcement of safety measures needs to be completely overhauled is \hat p=0.76.
