Answer:

(x ,y) =(-1,-1)

Step-by-step explanation:

$\left \{ {{y=6-7} \atop {x=6-7}} \right.$

$\left \{ {{y=-1} \atop {x=-1}} \right.$

(x,y) =(-1,-1)

Answer:

<h2>The domain would be -1</h2>

Step-by-step explanation:

The given function is

$y=x=6-7$

This expression expresses that both expressions are equal, that is

$y=6-7=-1\\x=6-7=-1$

So, basically the function can be expressed as $(-1,-1)$ . In other words, the function is only a point.

Therefore, the domain would be -1 and the range -1. Because the only element for <em>x </em> is -1 and the only element for y is -1.

FAST!! Evaluate tan60/cos45<br> √6<br> √3/2<br> √2/3<br> 1√6

evablogger [386]

Answer:

$\frac{\tan 60\degree}{\cos45 \degree}= \sqrt{6}$

Step-by-step explanation:

We want to evaluate

$\frac{\tan 60\degree}{\cos45 \degree}$

We use special angles or the unit circle to obtain;

$\frac{\tan 60\degree}{\cos45 \degree}=\frac{\sqrt{3}}{\frac{\sqrt{2}}{2}}$

This implies that;

$\frac{\tan 60\degree}{\cos45 \degree}=\sqrt{3}\div \frac{\sqrt{2}}{2}$

$\frac{\tan 60\degree}{\cos45 \degree}=\sqrt{3}\times \sqrt{2}$

$\frac{\tan 60\degree}{\cos45 \degree}= \sqrt{6}$

Use the confidence interval to find the estimated margin of error. Then find the sample mean. A biologist reports a confidence i

Pavlova-9 [17]

Answer:

$\bar X = \frac{Lower +Upper}{2}$

$\bar X= \frac{1.9+3.3}{2}= 2.6$

And the margin of error with this one:

$\bar X = \frac{Upper-Lower}{2}$

$ME = \frac{3.3-1.9}{2}= 0.7$

Step-by-step explanation:

Assuming that the parameter of interest is the sample mean $\mu$ . And we can estimate this parameter with a confidence interval given by this formula:

$\bar X \pm t_{\alpha/2}\frac{s}{\sqrt{n}}$ (1)

For this case the confidence interval is given by (1.9, 3.3)

Since the confidence interval is symmetrical we can estimate the sample mean with this formula:

$\bar X = \frac{Lower +Upper}{2}$

$\bar X= \frac{1.9+3.3}{2}= 2.6$

And the margin of error with this one:

$\bar X = \frac{Upper-Lower}{2}$

$ME = \frac{3.3-1.9}{2}= 0.7$
