Answer:

1: This is a 8-sided polygon, so it is a octagon.

2: No, this is not a regular polygon.

Step-by-step explanation:

1: Since the polygon has 8 sides, it is an octagon.

This is not a regular polygon.

Regular polygons MUST be equilateral and equiangular.

This polygon is neither, so it is not a regular polygon.

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.

Let p = true percentage of the population that suffers from extreme shyness.

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

Alternate Hypothesis, $H_A$ : P > 4.1%

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

On the other hand, alternate hypothesis states that 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.

Write the word sentence as an inequality. Then solve the inequality.

Agata [3.3K]

The solution is x>18.

The problem tells us that 3 less than a number: x-3
is more than 15. >15
So the inequality is x-3>15. When we isolate x to simply the inequality, we add 3 to both sides, to get x>18.

Describe what happens when two intersecting lines form a linear pair of congruent angles. Explain how you can get eight congruen

Charra [1.4K]

The angles diagonally opposite each other are congruent while those adjacent to each other add up to 180 degrees. You can get eight congruent angles with a transversal if the two lines are parallel, because each angle would be 90.

HELP ASAP!!!!! SOMEONE HELP ME?!?!

Kitty [74]

Answer:

The first step when factoring any polynomial is to factor out the GCF. The GCF is the greatest common factor for all the terms of the polynomial. By factoring out the GCF first, the coefficients and constant term of the polynomial will be reduced.
