The probability of getting 2 the same color is 9/11.

What is probability?

  According to the probability formula, the probability of an event occurring, or P(E), is equal to the proportion of positive outcomes to all outcomes. P(E) is defined mathematically as favorable outcomes divided by total outcomes. Mathematical branch known as probability deals with determining the possibility of an event occurring. Here using probability we can also calculate combination .

Here the total number of marbles are,

=>Total marbles = Blue + Red + Green

=>Total marbles = 5 + 4 + 3

=>Total marbles = 12

Then, Probability of a green = 3/12

=> Probability of not green = 1 - 3/12 = 9/12=3/4

To get exactly one green in two draws, we either get a green, not green, or a not green, green

=>First Draw Green, Second Draw Not Green

=> 1st draw: Probability of a green = 3/12

In 2nd draw: Probability of not green = 9/11 <-- 11 since we did not replace the first marble

To get the probability of the event, since each draw is independent, we multiply both probabilities

=> Probability of the event is (5/12) * (9/11) = 45/132

First Draw Not Green, Second Draw Not Green

=>1st draw: Probability of not a green = 9/12

=>2nd draw: Probability of not green = 7/11 <-- 11 since we did not replace the first marble

To get the probability of the event, since each draw is independent, we multiply both probabilities

=>Probability of the event is (9/12) * (7/11) = 63/132

To get the probability of exactly one green, we add both of the events:

First Draw Green, Second Draw Not Green + First Draw Not Green, Second Draw Not Green

=> 45/132 + 63/132 = 108/132=9/11.

Hence the probability of getting 2 the same color is 9/11.

Answer:

9 m , 23 m , 23 m

Step-by-step explanation:

let the third side be represented by x , then the 2 equal sides are

3x - 4 and 3x - 4

the perimeter (P) is the sum of the 3 sides

P = x + 3x - 4 + 3x - 4 = 7x - 8

given P = 55 m , then equating

7x - 8 = 55 ( add 8 to both sides )

7x = 63 ( divide both sides by 7 )

x = 9

3x - 4 = 3(9) - 4 = 27 - 4 = 23

sides of triangle are 9 m , 23 m and 23 m

i think there is something missing.

does this mean the 6 students paint 1/4 of the wall ?

so, each student then paints 1/6 of the 1/4 wall.

that means

1/4 / 6 = 1/4 / 6/1

now, remember, to divide by a fraction is the same as multiplying with the upside-down fraction.

so,

1/4 / 6/1 = 1/4 × 1/6 = 1/(4×6) = 1/24

every student is therefore painting 1/24 of the wall.

Answer:

36cm² is the answer.....

An expression for the measure  β° is 180 - x

The correct answer is an option (d)

We know that the sum of four angles of the quadrilateral is always 360°

In the attached quadrilateral angle A and angle D measures 90 degrees respectively.

The measure of ∠ABC in the figure is x° and the measure of ∠BCD is β°

From above statement for quadrilateral ABCD we have,

⇒ ∠A + ∠B + ∠C + ∠D = 360°

⇒ 90° + x°+ β° + 90° = 360°

⇒ x° + β° = 360° - 180°

⇒ x° + β° = 180°

⇒ β = 180 - x

Therefore, the required expression is β = 180 - x

The correct answer is an option (d)

Answer:

A graph is a function if it passes the vertical line test, meaning that no vertical line intersects the graph at more than one point. If the graph does not pass this test, it is not a function.

The graph is a function if each input value (x-coordinate) corresponds to exactly one output value (y-coordinate). To determine if a graph is a function, we can apply the vertical line test. If a vertical line intersects the graph at more than one point, then the graph is not a function.

Let's consider an example. If we draw a vertical line that intersects the graph at multiple points, then it is not a function. However, if the vertical line intersects the graph at most one point for any given x-coordinate, then it is a function.

In a function, each x-coordinate has a unique y-coordinate. For instance, the point (1, 3) represents that when x=1, y=3. If there is another point on the graph that has the same x-coordinate but a different y-coordinate, then the graph is not a function.

In summary, a graph is a function if it passes the vertical line test, meaning that no vertical line intersects the graph at more than one point. If the graph does not pass this test, it is not a function.

A rational expression seems to be undefined when ever the denominator is zero.

Here given expression, 5/(x - 10)

The expression becomes undefined when denominator becomes 0.

So here, if x = 10 then the denominator becomes 0.

That is 5/10-10

= 5/0

which is undefined, when x = 10.

Given expression, 15/(y² + 4)

Step-by-step explanation:

250/9.99=25.0250... Round it to 25.03

The required converted value is $25.03, which is 250 pesos to U. S. dollars.

As we all know, unit conversion is the process of multiplying a provided quantity by a conversion factor that combines the two interconnected units.

To convert 250 pesos to U.S. dollars, we divide the amount of pesos by the exchange rate.

Here, the exchange rate is given as 9.99 pesos per U.S. dollar.

It is the process of assigning a quantity from one unit of measurement to another.

250 pesos / 9.99 pesos per U.S. dollar = 25.025 U.S. dollars

Rounding this to two decimal places, the conversion is approximately $25.03.

\(Perimeter = \frac{39t-4}{4}\)

Step-by-step explanation:

Given

\(Lengths: (2\frac{1}{4}t - 5), (4t + 3), (1/2t - 1), (3t + 2)\)

Required

Determine the perimeter

The perimeter is calculated as the sum of the lengths of the irregular shape.

i.e.

\(Perimeter = (2\frac{1}{4}t - 5) + (4t + 3) + (1/2t - 1) + (3t + 2)\)

Remove brackets

\(Perimeter = 2\frac{1}{4}t - 5 + 4t + 3 + 1/2t - 1 + 3t + 2\)

Collect Like Terms

\(Perimeter = 2\frac{1}{4}t +4t + 1/2t + 3t - 5 + 3 - 1 + 2\)

\(Perimeter = 2\frac{1}{4}t +4t + 1/2t + 3t -1\)

Convert mixed number to improper fraction.

\(Perimeter = \frac{9}{4}t +4t + 1/2t + 3t -1\)

Take LCM

\(Perimeter = \frac{9t + 16t + 2t + 12t}{4} -1\)

\(Perimeter = \frac{39t}{4} -1\)

Take LCM

\(Perimeter = \frac{39t-4}{4}\)  --- The perimeter of the shape

We want to find the perimeter of the irregular quadrilateral given that we know its lengths. By direct computation, we will get:

P(t) = (39/4)*t - 1

Remember that for any figure, the perimeter is defined as the sum of the lengths of each side.

Here we have that the lengths of the four sides of the quadrilateral are:

(2 1/4t - 5)

(4t + 3)

(1/2t - 1)

(3t + 2)

So we must sum that, we will get:

P = (2 1/4t - 5) + (4t + 3) + (1/2t - 1) + (3t + 2)

Notice that in the first part we have a mixed number, we can rewrite it as:

2 + 1/4 = 8/4 + 1/4 = 9/4

Then the sum is:

P = ((9/4)t - 5) + (4t + 3) + (1/2t - 1) + (3t + 2)

Now we simplify this sum:

P = (9/4 + 4 + 1/2 + 3)*t + (-5 + 3 - 1 + 2)

P = (39/4)*t - 1

So the perimeter, as a function of t, is:

P(t) = (39/4)*t - 1

The angle ∠2 is a vertically opposite angle to the angle 145°, so they are congruent:

∠2 = 145°

The angles 1 and 3 are supplementary angles to the angle 145°, so they are equal to:

180° - 145° = 35°

∠1 = 35°

∠3 = 35°

The angle 8 is a corresponding angle to the angle 145°, so they are congruent:

∠8 = 145°

The angle ∠6 is a vertically opposite angle to the angle ∠8 so they are congruent:

Step-by-step explanation:

1.y = x * (1-0.4)

2.y = x - 0.4x

3.x = y / (1-0.4)

4.x = y + 0.4y

The equation 1 and 2 correctly represent the situation. In the first equation, we are multiplying the initial amount of water (x) with (1-0.4) which is the percentage of the water that is remaining after drinking 40% of it. In the second equation, we are subtracting 0.4x from x, which is equivalent to multiplying x by (1-0.4).

The equation 3 and 4 are not correct, as they are trying to calculate the initial amount of water from the remaining amount, but it's not possible to know the initial amount once it has been consumed.

You have 0.6X amount water remaining.

The amount of water remaining in the water bottle is X minus 40%. This means that if you had X amount of water at start you now have 60% of X left.  That is, you have 0.6X amount of water remaining.

This is because the Pythagorean Theorem states that the square of the length of the hypotenuse of a right triangle is equal to the sum of the squares of the lengths of the other two sides.

Pythagorean Theorem is an essential mathematical principle that has been used for centuries. It states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the other two sides. This theorem is named after the ancient Greek mathematician Pythagoras. Using this theorem, one can calculate the length of any side of a right triangle if the lengths of the other two sides are known.

This relationship between the side lengths and the angle measures can be used to calculate the exact angle measures when all three side lengths are known.
