A bag contains 2 red pens, 4 blue pens, 3 black pens, and 1 green pen. Once a pen is selected, it is replaced, and then another pen is selected. Determine P(blue and blue)

Answers

Given:

A bag contains 2 red pens, 4 blue pens, 3 black pens, and 1 green pen.

Once a pen is selected, it is replaced, and then another pen is selected.

To find:

The probability of getting blue pens in both draws, i.e., P(blue and blue).

Solution:

We have,

Number of red pens = 2

Number of blue pens = 4

Number of black pens = 3

Number of green pen = 1

Total number of pens = [tex]2+4+3+1[/tex]

                                    = [tex]10[/tex]

The probability of getting a blue pen is:

[tex]P(\text{Blue})=\dfrac{\text{Number of blue pens}}{\text{Total number of pens}}[/tex]

[tex]P(\text{Blue})=\dfrac{4}{10}[/tex]

[tex]P(\text{Blue})=0.4[/tex]

Once a pen is selected, it is replaced, and then another pen is selected. So, after replacement the probability of getting a blue is remains the same.

[tex]P(\text{Blue and Blue})=P(\text{Blue})\times P(\text{Blue})[/tex]

[tex]P(\text{Blue and Blue})=0.4\times 0.4[/tex]

[tex]P(\text{Blue and Blue})=0.16[/tex]

Therefore, the value of [tex]P(\text{Blue and Blue})[/tex] is 0.16.

Answers

Answer:

5 felt pads.

7 cards.

Step-by-step explanation:

Remark

The total number of items is 12 So let the felt sheets be xLet the cards = y

Equations and Solution

x + y = 12

Now the price is 7.75 that she has to pay for the 12 items. She wants to come back with 0 dollars.

0.5x + 0.75y = 7.75             Multiply this equation by 2

x + 1.5y = 15.50                    write the first equation underneath and subtract.

x +    y =   12

      .5y =  3                          Divide by 0.5

y = 3/0.5

y = 7

So she can get 7 cards.

x + y = 12

x + 7 = 12

x = 12 - 7

x = 5

So she can buy 5 felt pads.

can someone please help me find the answer to this they want me to find the surface area of it

Answers

Answer:

Step-by-step explanation:

You have three rectangular faces and two triangular faces. Each rectangular face has an area equal to xy. Each triangular face has an area equal to xy/2. So the total area will be

A=5(7)+3(7)+4(7)+4(3)/2+4(3)/2

A=35+21+28+6+6

A=96cm^2

Answer:

as below    

Step-by-step explanation:

add up the surface area of each side of this object

this object has 5 sides

2 of the sides are equal triangles so we could add those up to make one whole rectangle.  and if we do that then there are only 4 sides

the two triangle sides add up to one rectangle side of 4 *3 = 12

the bottom side facing downwards = 3 * 7 = 21

the back side facing away  = 4 * 7 = 28

the front side at an angle = 7 * 5 = 35

12 + 21 + 28 + 35 = 96 [tex]cm^{2}[/tex]
