     "Not independent" means that the situation is dependent. It is not relying on something else, or something else will not change the outcome. Independent means the situation is isolated, it is independent.

A jar contains green marbles and orange marbles. A green marble is selected followed by an orange marble, at random, without replacement.

Not independent

-> Since the marbles are not being replaced, this isn't independent

Picture 2: Law of Sines

Answer:

4

Step-by-step explanation:

okay, so she rode 3 miles. Keep that aside

Then she had 2 walk the remaining 2 miles

She had to walk all the way home. So say for example instead of riding she walked 3 miles, then she walked that additional 2 miles. So, 5 miles. Then add the two miles she had to walk to his house. so, she walked 7 miles and rode 3 miles. 7-3= 4 miles. I attached a picture that should hopefully explain it better.

Answer:

x = 19; y = 19√3

Step-by-step explanation:

sin 30° = opp/hyp

sin 30° = x/38

x = 38 × sin 30°

x = 19

cos 30° = adj/hyp

cos 30° = y/38

y = 38 × cos 30°

y = 38 × √3/2

y = 19√3

Answer:

about a 9.5 percent chance of both being a milky way

Step-by-step explanation:

Probability that both candy bars were milky way is [tex]\frac{2}{21}[/tex]

Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur

Given,

Number of snickers bars = 5

Number of Milky way bars =9

Number of crunch bars = 2

Number of Twix bars = 12

Total number of Candy bars = 5+9+2+12 =28

If Jack randomly selects a candy bar, eats it, then randomly selects another

Probability = Number of favorable outcome / Number of total outcome

Probability of taking Milky way bar in first pick = [tex]\frac{9}{28}[/tex]

So Total number of candy bars and number of Milky way bar are decreased by 1.

Probability of taking Milky way bar in second pick = [tex]\frac{8}{27}[/tex]

Probability that both candy bars were milky way = [tex](\frac{9}{28}).(\frac{8}{27})=\frac{2}{21}[/tex]

Hence, Probability that both candy bars were milky way is [tex]\frac{2}{21}[/tex]

A triangle has an area of 66 in². If the base is 11 inches, what is the height?

The height of the triangle is 12 inches.

As per the provided information in the given problem, we know that the area of a triangle is given by 66 inches². The base of the triangle is given by 11 inches. In this problem, we are tasked to find the height of the triangle.

To do this, we will use the formula below:

[tex]\Large\begin{aligned}\rm\qquad\dashrightarrow{Area_{(Triangle)} = \dfrac{1}{2}bh}\end{aligned}[/tex]

Where:

Substitute the given values into the formula given earlier and solve for h:

[tex]\Large\begin{aligned}\rm\dashrightarrow{Area_{(Triangle)}}& = \rm{\dfrac{1}{2}bh}\\\rm\dashrightarrow{66\: in^2}& = \rm{0.5(11\: in)(h)} \\\rm\dashrightarrow{66\: in^2}& = \rm{(5.5\: in)(h)} \\\rm\dashrightarrow{\dfrac{66\: in^{\cancel{2}}}{5.5\: \cancel{in}}}& = \rm{\dfrac{(\cancel{5.5\: in})(h)}{\cancel{5.5\: in}}} \\\rm\dashrightarrow{12\: in}& = \rm{h}\end{aligned}[/tex]

Hence, the height of the triangle is 12 inches.

Answer: First find the volume of the rectangle prism. Do this by multiplying all three dimensions. 412 x 412 x 6 = 1,018,464.

Subtract 1,018,464 from 143.

You should get 1,018,321 mm^3

(Remember that the units are cubed because you multipled 412 mm x 412 mm x 6 mm which is multiplying not only the numbers, but the mm three times as well.)

Answer:

r = t + q - s

Step-by-step explanation:

t = r - q + s

goal is to isolate the variable

add q to both sides (this cancels the q out on the right side)

t + q = r - q + q + s

t + q = r + s

subtract s from both sides

t + q - s = r + s - s

t + q - s = r

In other words:

r = t + q - s

It still counts

Answer:

5 inches and 4 inches

Step-by-step explanation:

The perimeter is equal to 2(2x + 1) + 2(x + 2) since there are two sides of the rectangle equal to the expressions given.

Since we also know that the perimeter is 18 inches, we can set that equal to 18.

2(2x + 1) + 2(x + 2) = 18

4x + 2 + 2x + 4 = 18

6x + 6 = 18

6x = 12

x = 2

After plugging 2 back into 2x + 1 and x + 2, you get 5 and 4. Hope this helped!
