13. Express the null hypothesis and the alternative hypothesis in symbolic form. Use the correct symbol (u, P, o) for the indica

liraira [26]

Answer:

Null Hypothesis, $H_0$ : P = 4.1%

Alternate Hypothesis, $H_A$ : P > 4.1%

Step-by-step explanation:

We are given that a psychologist claims that more than 4.1% of the population suffers from professional problems due to extreme shyness.

<u><em>Let p = true percentage of the population that suffers from extreme shyness.</em></u>

So, Null Hypothesis, $H_0$ : P = 4.1%

Alternate Hypothesis, $H_A$ : P > 4.1%

Here, <em><u>null hypothesis states that</u></em> % of the population who suffers from professional problems due to extreme shyness is equal to 4.1%.

On the other hand, <u><em>alternate hypothesis states that</em></u> more than 4.1% of the population suffers from professional problems due to extreme shyness.

So, the above hypothesis would be appropriate for conducting the test.

The lengths of the sides of a triangle are 3, 4, 5. Can the triangle be a right triangle?

Contact [7]

Answer:

Yes it can

Step-by-step explanation:

To check wether it's a right angle triangle we need to apply the Pythagoras theorem

h^2= a^2 +b^2

Hypotenuse is always the longest side so

5^2 = 3^2 + 4^2

This is correct, so the triangle is a right angle triangle

What is (14x^2– 27x+9) / (7x-3)?<br><br> A. 7x-3<br> B. 2x-3<br> C. -211x+9<br> D. 2x-33

Yakvenalex [24]

Answer:

B. 2x - 3

Step-by-step explanation:

$\rm \frac{ {14x}^{2} - 27x + 9}{7x - 3}$

$\rm = \frac{ \cancel{(7x - 3)}(2x - 3)}{ \cancel{7x - 3}}$

$\boxed{ \rm \bold{= 2x - 3}}$
