A container has 5 green, 4 yelow and 2 whhite marbles. Carla chooses a marble without looking. Is it the probability that she will select a green marble closest to 0, 1/2 or 1? What is P (white)

Answers

Step-by-step explanation:

A container has 5 green, 4 yellow and 2 white marbles.

We need to find the probability of selecting a green marble.

The probability of getting an event is given by :

P(E) = favorable outcomes/no. of outcomes

The probability of getting green marble will be :

[tex]P(G) = \dfrac{5}{5+4+2}\\\\=\dfrac{5}{11}[/tex]

The probability of getting white marble will be :

[tex]P(W) = \dfrac{2}{5+4+2}\\\\=\dfrac{2}{11}[/tex]

Hence, this is the required solution.

Answer:

3 cm

Step-by-step explanation:

Answer:

2.5cm

Step-by-step explanation:

The shapes are similar and so have a scale-factor. We can find the scale-factor by dividing one of the lengths that we know on the bigger shape by the corresponding side on the smaller shape.

For example: PQ/LM = 6/3 = 2

Now that we know to get from the larger shape to the smaller shape, we have to multiply by 2. We can use this scale factor to find the length of the side MN.

QR = MN x 2

MN = QR/2 = 5/2 = 2.5cm

The hanger image below represents a balanced equation,

Find the value of d that makes the equation true.
MY
d=

Answers

Answer:

The value of d that balances the equation is d=15

Step-by-step explanation:

Equations

We are given an image with a hanger that represents a balanced equation.

If the equation is balanced, then the 'weights' of each side should be equal.

On the right side, there is 21 and on the left side, there are 6 and d.

Adding both, we have 6+d on the left side.

Equating both sides:

6 + d = 21

To find d, we subtract 6 on both sides:

d = 21 - 6

d = 15

The value of d that balances the equation is d=15

Answer:

d=15

Step-by-step explanation:

6+d=21

so that means d=15

6+15=21

What is the Pythagorean Theorem? Provide the equation and an explanation as to what it means.

Answers

Answer:

The Pythagorean Theorem is a squared + b squared = c squared. It is used to find out a side of a triangle if you already know the two others. C is always the H=hypotenuse, while the other two sides are a and b.

Answer: a^2+b^2 (factored) = c^2

Step-by-step explanation:

This only helps if you are solving for the hypotenuse.

Harold earns $10.50 per hour working at a doctor's office. On Monday he spent 1 5/12 hours filing paperwork, 1 3/4 sending emails and 2 1/3 hours making appointments. What were Harold's earnings? Round your answer to the nearest cent.

Answers

Answer:

the total earnings is $58

Step-by-step explanation:

The computation of earnings is shown below:

= Time spent in filling paperwork + time spent in sending emails + time spent in making appointments

= (1 5 ÷ 12 × $10.50)  + (1 3 ÷ 4 × $10.50)  + (2 1 ÷ 3 × $10.50)

= 14.875 + 18.375 + 24.50

= $57.75

Hence, the total earnings is $58

The same is to be considered
