Step-by-step explanation:

Chance of getting yellow first time: [tex]\frac{2}{13}[/tex]

Chance of getting green without replacement from yellow: [tex]\frac{5}{12}[/tex]

Chance of getting red without any replacement: [tex]\frac{6}{11}[/tex]

Answer:

5

Step-by-step explanation:

Raman have 72.75 M long string and he cut the string in pieces of equal length of 14.55 M long .

To find how many pieces he cut, we simply divide the length of the original piece of string by the length of the cut piece of string.

That is:

72.75 / 14.55 = 5

He can cut 5 pieces of string.

Answer:

b

Step-by-step explanation:

Answer:

The y-intercept is represented by the variable b in this equation.

Answer:

x intercept = -0.25

y intercept = 4

Step-by-step explanation:

  1.- remove parenthesis

y-3 = 1/2x +1

  2.- adjust to equal y

y = 1/2x +1 +3

y = 1/2x +4

  3.- guess values for x to try in the simplified equation.

x = -0.25 | y = 0

x = 0       | y = 4

x = 2       | y = 5

x = -2      | y = 3

x = 4       | y = 6

x = -4      | y = 2

  4.- graph all coordinates (x,y). Draw a line connecting each dotted coordinate.

Answer: 60 cm²

Step-by-step explanation:

This is pretty simple, we know AB is 12 cm and DE is 4 cm. We know ABC has a total of 180 square centimeters. So...

12 ÷ 3 = 4

180 ÷ 3 = 60

The answer is 60 cm²

Answer:

9.4 miles

Step-by-step explanation:

We can assume that if these joggers run 8 miles north, consecutively 5 miles west, these lengths form legs of a right angle triangle, from which we have to determine the hypotenuse of the triangle provided it would lead to the shortest route possible;

Knowing this is a right angle triangle, let us apply Pythagorean Theorem to solve for the length of this hypotenuse, which we can assign as x;

8^2 + 5^2 = x^2 ⇒ square 8 and 5,

64 + 25 = x^2 ⇒ Combine like terms,

x^2 = 89 ⇒ Take square root on either side

Solution; Shortest Distance ⇒ length of 9.4 miles

Answer: $5.5

Step-by-step explanation:

Here is the complete question:

L.B. Johnson Middle School held a track and field event during the school year. The chess club sold various drink and snack items for the participants and the audience. Altogether, they sold 486 items that totaled $2,673 a. If the chess club sold each item for the same price, calculate the price of each item. b. Explain the value of each digit in your answer to a using place value terms

Item sold = 486

Total amount = $2673

Price of each item = Total amount/items sold

= 2673/486

= $5.5

Each item costs $5.5.

5.5 = 5 units and 5 tenths.

The first number after the decimal point by the right is the tenths.

Answer:

A.

Step-by-step explanation:

Given that point P partitions a directed line segment from A to B into the ratio 3:4, we are to determine how close P is to either A or B.

To do this, we take an example.

Let the length of line segment AB be 14 Units.

Since P divides AB in the ratio 3:4

Therefore, from the above, we can conclude that P will be closer to A as its distance from A is shorter than its distance from B.

The correct option is A.

Answer:

Point P partitions the directed line segment from A to B into the ratio 3:4. Will P be closer to A or B? Why?

A number line goes from point A to point B. A line is drawn from point A to point B.

Right Answer  A.)   P will be closer to A because it will be Three-sevenths the distance from A to B.  

Wrong Answer  B.)   P will be closer to A because it will be Four-sevenths the distance from A to B.

Wrong Answer C.)    P will be closer to B because it will be Three-sevenths the distance from B to A.

Wrong Answer D.)   P will be closer to B because it will be Four-sevenths the distance from B to A.

Step-by-step explanation:

The expression for the radius of the cylinder is r = 2x units

A cylinder is a three-dimensional shape consisting of two parallel circular bases, joined by a curved surface. The center of the circular bases overlaps each other to form a right cylinder. The volume of a cylinder is

Volume of Cylinder = πr²h

Surface area of cylinder = 2πr ( r + h )

where r is the radius of the cylinder

h is the height of the cylinder

Given data ,

Let the volume of the cylinder be represented as V

Now , the value of V is

V = 4πx³ units

where the height of the cylinder is h = x units

So , the Volume of Cylinder = πr²h

On simplifying , we get

4πx³ = πr²h

Substituting for h , we get

4πx³ = πr² ( x )

Divide by πx on both sides , we get

r² = 4x²

Taking square roots on both sides , we get

r = 2x units

Therefore , the value of r is 2x units

Hence , the radius of the cylinder is 2x units

Statistical

Step-by-step explanation:

You need to collect data to determine the answer of that.

Answer:

Yes

Step-by-step explanation:

"How many apps do my classmates have on their phones?" This is a statistical question because a statistical question has to be a question that can be used to collect data. If the question was something like "How many apps does Melissa have on her phone?" it would NOT be a statistical question because it is only asking about one specific person and you wouldn't be collecting data.

I wasn't really sure how to explain it but I hope it makes sense! :)

Answer:

3017.5 cm³

Step-by-step explanation:

The volume of a rectangular prism is V = l × w × h

Here the length is 14.2, the width is 12.5, and the height is 1

Plugging these into our formula we get V = (14.2)(12.5)(1) = 177.5 cm³

Since there are 17 CD cases stacked on top of each other, we will multiply our number by 17 which gives us (177.5)(17) = 3017.5 cm³

I'm going to assume that you are trying to find the volume of a rectangular prism.

Volume formula: V = lhw

V = 10*9*7

V = 90*7

V = 630

Therefore, the volume is 630mi³

The pattern of numbers can be re-written in the form below:

[tex]\left\begin{array}{ccccccccccccc}&&&&&&1&&&\\&&&&&1& &1&&&\\&&&&1& &2 &&1\\&&&1 &&3 &&3 &&1\\ &&1 &&4 &&6&& 4&& 1\\ &1 &&5&&10&&10&&5&&1\\ 1 &&6 &&x &&20&& x &&6 &&1\end{array}\right \\[/tex]

The triangular array which involves summing adjacent elements in preceding rows is referred to as the Paschal's Triangle.

Taking the 6th and seventh row, the adjacent elements in the 6th row are summed on the Left Hand sides and the result from the seventh row is given on the right hand sides of the equations below.

We can then see that:

Step-by-step explanation:

Answer:

See explanation below

Step-by-step explanation:

In picture attached I manage to find one graph. Just follow the explanation of this, if your graph data is different than this.

According to the attached graph we can see that the line of the graph is beggining at 12. So we this, we can assume and say that the initial height of the swimmer is 12 ft.

The max height would be the maximum point in the graph where it reach the maximum height. In other words, the highest point of the line. since the beggining of the jump. As you can see in the graph, this is reached between 22 and 24 ft. So we can assume is around 23 ft. So the maximum height would be 23 ft

Finally the x-intercept, would be the point of the line where it reach the x-axis. In this case, it would be a point really close to 8. You can say it's about 7.8, or even the number 8 if you wish. In this case, let's say it's 7.8 the x-intercept

Answer:

67

Step-by-step explanation:

Multi-Inscribed Quadrilateral: 15

Bananas: 4

Clock: 3

Therefore, we can substitute for the last equation the values, so it would become:

3 + 4 + 4 x 15 = ?

First, we solve the multiplication according to PEMDAS.

4 x 15 = 60

Then, we can add from left to right.

3 + 4 + 60 = ?

3 + 4  = 7

7 + 60 = 67

Therefore, our answer would be 67.

Answer:

[tex]15 + 15 + 15 = 45 \\ 4 + 4 + 15 \: \: \: \: = 23 \\ 4 + 3 + 3 = 10 \\ 3 + 4 + 4 \times 11 = 51[/tex](according to BODMAS)

Step-by-step explanation:

First divide 45 by three

[tex]45 \div 3 = 15[/tex]

then subtract 15 from 23 and divide that answer by 2

[tex]23 - 15 = 8 \\ 8 \div 2 = 4[/tex]

Now subtract 4 from 10 and then divide that answer by 2

[tex]10 - 4 = 6 \\ 6 \div 2 = 3[/tex]

Now add 3+4+4*11 you will get the answer for ?

[tex]3 + 4 + 4 \times 11[/tex]

3 + 4 + 44

7 + 44

= 51
