A bag contains 1 blue, 2 green, and 2 red marbles. You choose a marble with one hand and then a second marble with the other hand. What is the probability that you will first choose a red marble followed by a green marble?

Answers

Answer 1

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

Probabilities

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 = 52/5 x 2/4 = X0.4 x 0.5 = X0.2 =X0.2 x 100 = 20

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

Answer 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

Data;

blue = 1green = 2red = 2

Probability without replacement

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

The total number of marbles in the bag is

[tex]1 + 2 + 2 = 5[/tex]

The probability of choosing a red marble is

Number of read marbles = 2

probability of choosing a red marble is

[tex]P = \frac{2}{5}[/tex]

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

[tex]P = \frac{2}{4} =\frac{1}{2}[/tex]

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

Answers

Answer:

10.1119 m or √102.25 m

Step-by-step explanation:

Using our lovely Pythagorean theorem, a² + b² = c², we can find the value of x in this triangle.

Let's say that a = 4.8 and b = 8.9, then set c as x.

(4.8)² + (8.9)² = x²

23.04 + 79.21 = x²

x² = 102.25

x = √102.25

Answers

Answer:

Step-by-step explanation:

you can re-write 3 1/2 hours into minutes.

1 hr = 60 minutes,

Therefore:

3 1/2 hours = 3.5 times 60 = 210 minutes

So now we have the ratio:

3 1/2 hours : 36 minutes

210 minutes : 36 minutes

Both numbers can be divided by 6

210/6 = 35 and 36/6 = 6

So now we can re-write the ratio as :

What will be the final price of the better deal?

$524.99
$572.94

Answers

First let's calculate the final price at the electronic store.

499.99*(1+0.05)≈524.99

Now let's calculate the final price online

(549.99+22.95)*(1-0.1)≈515.65

If we compare the two we can see that the online price is cheaper at around 515.65 dollar therefore the second choice is correct.

A tree from a forest with a height of 30 feet is shown below the bottom branches are about 4 feet from the ground and are 10 feet long from left to right.the tree trunk is about 2 feet wide.
what are the appropriate shapes to model the trunk of the tree and the rest of the tree?what are the approximate surface areas of each of the two shapes?

Answers

Answer: cone Cylinder

Surface area is 402ft2 and 69ft2

Step-by-step explanation:

I got the answer right

The appropriate shape to model trunk is cylinder, rest of the tree is cone and surface area of trunk is 25.12 [tex]feet^{2}[/tex]and surface area of rest of the tree is 415.58 [tex]feet^{2}[/tex].

What is surface area?

It is the space occupied by a two dimensional surface. The area occupied by a three dimensional object by its outer surface area.

How to calculate surface area?

The upper part of the tree is similar to the cone and the trunk is of cylindrical shape. So the appropriate shape used to model the entire is cone above the cylinder.

We have been given the height of entire tree=30 feet,

Width of upper part=10 feet.

Height of trunk=4 feet

Width of tree means diameter of upper part or cone. Height of cone means height of cylinder, width of trunk means diameter of cone.

So, The radius of cone ie 5 feer,radius of cylinder is 1 feet, height of cone be 30-4=26 feet.

Surface area of cone is πrl where l is slant height of cone which is equal to [tex]\sqrt{r^{2} +h^{2} }[/tex]

l=[tex]\sqrt{5^{2} +26^{2} }[/tex]

=[tex]\sqrt{701}[/tex]

=26.47 feet.

Surface area of cone=π*5*26.47

=3.14*5.26*26.47

=415,28 [tex]feet^{2}[/tex]

Surface area of cylinder=2πrh

=2π*4*1

=2*3.14*4

=25.12 [tex]feet^{2}[/tex]

Hence cone and cylinder of surface area 415.28 [tex]feet^{2}[/tex] and 25.12 [tex]feet^{2}[/tex] can be used to model out tree.

Solve each system of equations 2a+b+c=0 2b+c+a=-4 2c+a+b+4

Answers

Answer:

  (a, b, c) = (0, -4, 4)

Step-by-step explanation:

Any of a variety of calculators, spreadsheets, or web sites can solve these equations for you. A calculator result is attached. It shows the solution to be ...

  (a, b, c) = (0, -4, 4)

__

If you'd like to solve the system by hand, here's one way:

Add the three equations together:

  (2a +b +c) +(2b +c +a) +(2c +a +b) = (0) +(-4) +(4)

  4a +4b +4c = 0 . . . . simplify

  a +b +c = 0 . . . . . divide by 4

Substitute this into each of the other equations:

  a +(a +b +c) = 0   ⇒   a +0 = 0   ⇒   a = 0

  b +(a +b +c) = -4   ⇒   b +0 = -4   ⇒   b = -4

  c +(a +b +c) = 4   ⇒   c +0 = 4   ⇒   c = 4

The answer is 24 bud it’s not that hard to find it lol

The daily expense for food and lodging will be 337.

What is the z-score?

The z-score is a statistical evaluation of a value's correlation to the mean of a collection of values, expressed in terms of standard deviation.

The z-score is given as

z = (x - μ) / σ

Where μ is the mean, σ is the standard deviation, and x is the sample.

A recent survey by the American Automobile Association showed that a family of two adults and two children on vacation in the United States will pay an average of $247 per day for food and lodging with a standard deviation of $60 per day.

Assuming the data are normally distributed if the family had a z-score of 1.5.

Then the daily expense for food and lodging will be

z = (x - μ) / σ

1.5 = (x - 247) / 60

90 = x - 247

x = 247 + 90

x = 337

The daily expense for food and lodging will be 337.
