Answer:

$\textbf{$a + bi = 2 + i$}\\$

Step-by-step explanation:

$\textup{Given:}\\$$\frac{4 + \sqrt{16 - (4)(5)}}{2}$$\\\textup{This can simplified as:}\\\vspace{6mm}\\$

$\frac{4 + \sqrt(-4)}{2}$\vspace{6mm}\\$\implies \frac{4 + 2i}{2}$\vspace{5mm}\\$\implies 2 \left( \frac{2 + i}{2} \right)$\vspace{5mm}\\$$\therefore a + bi = 2 + i$$

Answer:

Step-by-step explanation:

Corresponding angles are angles that you can follow down the transversal and they will land in the same spot on the other parallel line. Look at angle 8. It is the bottom left angle in the group of 4 angles around it. If you slide it to the left it would land right on top of angle 4 which is also in the bottom left of its group of 4 angles.

You can do the same thing taking angle 8 down to angle 12.

Answer:

The correct null hypothesis in words is:

D. The long-run proportion of private colleges in the US, that have tenure-track faculty is 0.5.

$H_0: \pi = 0.5$

Step-by-step explanation:

He wants to test the claim that the proportion of private schools that have avenues for professors to apply for tenure is significantly higher than 0.5, as happen with the public schools.

Then, the alternative hypothesis is:

$H_a: \pi >0.5$

The null hypothesis represents the opposite claim, where the proportion is not significantly higher than 0.5. Then, the null hypothesis is expressed as:

$H_0: \pi = 0.5$

The correct null hypothesis in words is:

D. The long-run proportion of private colleges in the US, that have tenure-track faculty is 0.5.

Serga [27]

<span>ax + by + c = 0
by = - ax - c
y = -a/b (x) - c/b

so slope = </span>-a/b

What’s the answer to this?<br> I have no idea how to do it

Nimfa-mama [501]

Answer:

Step-by-step explanation:

f(x) = y

To find f(2), it means to find the value of y when x = 2.

From the graph, when x = 2, the corresponding y-coordinate = 0.

Therefore,

f(2) = 0
