Roller staking is more popular because it has a higher amount of results.

The percentage of 8th graders that want to go to the water is 70%

<h3>What is a relative frequency?</h3>

The relative frequency of an event is the proportion of the total no. of a result under which a defined event occurred with respect to the whole actual event.

So, from the given table:

Roller staking is more popular because it has a higher amount of results.

$\mathbf{\implies \dfrac{x}{100}\times 0.20 = 0.14}$

$\mathbf{\implies0.20x = 14}$

$\mathbf{\implies x = 70\%}$

The percentage of 8th graders that want to go to the water is 70%

There is an association between the grade level and the field trip, this is because as the grade level increases, the field trip decreases.

If the trend continues, the 9th graders will prefer the water slides to the roller skating, this is because the proportion of the water slides is more than the roller skating down the trend.

The relationship of the given angles are:

1. A. Adjacent

2. B. vertical

3. B. vertical

4. E. linear pair

5. C. complementary

6. D. supplementary

7. C. complementary

8. A. adjacent

9. A. adjacent

10. D. supplementary

11. A. adjacent

12. C. complementary.

<h3>How to Determine the Relationship Between Angles?</h3>

Different pairs of angles are related to each other in several ways. The explanation below shows the relationship between the given angles.

1. Angles 2 and 3 share a common vertex and a common side, therefore:

<2 and <3 are: A> Adjacent

2. <3 and <4 are non-adjacent angles that share a common vertex and are opposite each other. Thus:

<3 and <4 are: B. vertical

3. <1 and <3 are: B. vertical

4. <1 and <2 lie on a straight line and are adjacent to each other. Therefore, they are a: linear pair

5. 78 + 12 = 90 degrees. Therefore, their relationship is that they are: C. complementary

6. 123 + 57 = 180. Therefore, they are: D. supplementary

7. Angles a and b form a right angle. Therefore, they are: C. complementary

8. <1 and <2 are: adjacent

9. <3 and <4 are: A. adjacent

10. 90 + 90 = 180, therefore, the angles are: D. supplementary

11. Both angles are: A. adjacent

12. 40 + 50 = 90 degrees. Therefore, the angles are: C. complementary.

A square is shown below. Which expression can be used to find the area, in square units, of the shaded triangle in the square?

AlexFokin [52]

The area of a square would me multiplying the width times the length and then multiplying by one half would be like splitting the square in half so your answer would be that last one right there. 6*6= area then multiply by 1/2 = half of area Hope this helps! :D

Urgent! Will award brainliest...<br> Factor the following polynomial:<br> <img src="https://tex.z-dn.net/?f=3a%5E%7B2%7D-21a%2B3

umka2103 [35]

Answer:

$3 (a-2) (a-5)$

Step-by-step explanation:

The first step is to find the GCF. Here, it's 3.

$3(a^2-7a+10)$

Then, you factor the polynomial in the parenthesis.

To find the factors, you will need to find 2 numbers that add to -7, and multiply to 10. -2 and -5 add to -7 and multiply to 10. Now, replace -7a with the factors.

$a^2-2a-5a+10$
