The probability that you will first choose a red marble followed by a green marble is 20%.

<h3><u>Probabilities</u> </h3>

Given that a bag contains 1 blue, 2 green, and 2 red marbles, and you choose a marble with one hand and then a second marble with the other hand, to determine what is the probability that you will first choose a red marble followed by to green marble the following calculation must be made:

  • 1 + 2 + 2 = 5
  • 2/5 x 2/4 = X
  • 0.4 x 0.5 = X
  • 0.2 =X
  • 0.2 x 100 = 20

Therefore, the probability that you will first choose a red marble followed by a green marble is 20%.

The probability of choosing a red marble is 2/5 while the probability of choosing a green marble after a red marble is 1/2

Data;

  • blue = 1
  • green = 2
  • red = 2

<h3>Probability without replacement</h3>

To solve this problem, we have to do probability without replacement.

The total number of marbles in the bag is

1 + 2 + 2 = 5

The probability of choosing a red marble is

Number of read marbles = 2

probability of choosing a red marble is

P = \frac{2}{5}

The probability of choosing a green marble after a red marble is

P = \frac{2}{4} =\frac{1}{2}

The probability of choosing a red marble is 2/5 while the probability of choosing a green marble after a red marble is 1/2

Answer:

The answer to the question is 50.28 feet²

Step-by-step explanation:

Here, is why the answer to the problem is 13.72!

The area of the shaded region is:-

Area of total region - Area of the circular region

Area of total region is 8² so it is 64 feet²

Area of Circular region formula is πr²

Substitute the values, for the formula and it is π4² = 22/7 × 16

                                                                         → 352/7

                                                                        ⇒ 13.72 Feet²

Therefore, the area of the shaded region is 13.72 Feet²

(Now, we subtract the two values)

64 - 13.72

⇒ 50.28 Feet²

I hope this answer helps!

Answer:

This should be parallel.

Step-by-step explanation:

Two lines are said to be parallel only if their slope matches. They are said to be perpendicular only if the slopes are negative reciprocals.

Here, you should put both equations in slope intercept form which is y=mx+b. The letter "M" represents the slope of both equations.

2y-6=3x+4 turns into 2y=3x+10 after adding 6 and into y=3/2x+5 after dividing the equation by 2. The slope for this equation is 3/2.

8y=12x+8 must be divided by 8 to be in slope intercept form. This equation becomes y=3/2x+1. Here the slope is also 3/2.

The slopes for each equation match making these lines parallel.

For an angle Θ with the point (12, −5) on its terminating side, what is the value of cosine?
Katyanochek1 [597]
Well, in order to answer this problem we need to use the <span>the Pythagorean Theorem and the  it will be like this:
cos = x / hypotenuse
cos= 12/13 
I think with this you can figure the rest out. Hope this helps</span>
