Answer:

h = 4/3

1/2 of 4/3 is 2/3

4/3 + 2/3= 6/3, or 2

Answer:

D.

Step-by-step explanation:

I would have to say D is the best answer since then it's truly based on luck and it's almost as if it's being flipped once

Hillary and her friends could flip a coin twice to fairly decide which activity they will do. If the coin lands on heads one time and tails one time, they will go bowling. If it doesn't, they will go to a movie.

Probability is the ratio that shows the likelihood of an event occurring out of all the other possible events.

Hillary and her friends need to use a fair method to determine which activity to do. For this, the probability should be 1/2. We should observe the given options and find which is the fairer method.

Therefore, Hillary and her friends could flip a coin twice to fairly decide which activity they will do. If the coin lands on heads one time and tails one time, they will go bowling. If it doesn't, they will go to a movie. The correct answer is Option B.

Answer:

Step-by-step explanation:

The slope of a line can be determined by any two points on the line and is defined as

m=(y2-y1)/(x2-x1),

We are given points (-14,3) and (2,-5) so

m=(-5-3)/(2-(-14))

m=(-8)/(16)

m= -1/2. (Answer F)

13.9

Step-by-step explanation:

Use the distance formula:

[tex]d = \sqrt{(x_2 - x_1)^2 + (y_2-y_1)^2}\\\\d = \sqrt{(7 - (-5))^2 + (-4-3)^2}\\d = \sqrt{(12)^2 + (-7)^2}\\d = \sqrt{144 + 49}\\d = \sqrt{193}\\[/tex]

The square root of 193 rounded to the nearest tenth is 13.9.

Hi there!

[tex]\large\boxed{(5,8) \text{ and } (1.2, -2.78)}}[/tex]

We are given the equation:

x² - 2y = 7

To verify if each ordered pair is apart of the function, we can plug in their respective x and y values:

1. (5)² - 2(8) = 7

25 - 16 = 9 ≠ 7. This is NOT correct.

2. (-1)² - 2(-3) = 7

1 + 6 = 7. This is correct.

3. (-4)² - 2(-11.5) = 7

16 + 23 = 39 ≠ 7. This is NOT correct.

4. (1.2)² - 2(-2.78) = 7

1.44 +5.56 = 7. This is correct.

Thus, only 1 and 4 are the correct answers.

No yes no yes

Answer/Step-by-step explanation:

a. First, find the value of a.

Sum of the interior angles of a triangle = 180° (triangle sum theorem)

Therefore:

3a + 2a + a = 180°

Add like terms

6a = 180°

6a/6 = 180/6

a = 30

Thus:

a = 30°

2a = 2(30) = 60°

3a = 3(30) = 90°

b. The triangle is an isosceles triangle because it has two sides that are indicated to be equal. This also implies that the angels opposite each of the equal sides are also congruent to each other.

Therefore, sum of the isosceles triangle would be:

2(2x) + 5x = 180°

4x + 5x = 180

9x = 180

9x/9 = 180/9

x = 20

Thus:

2x = 2(20) = 40

5x = 5(20) = 100

Answer:
