The probability that Ned will choose 2 red shirts randomly from the box is 1/35.

It is a branch of mathematics that deals with the occurrence of a random event.

The probability of choosing 2 red shirts randomly from the box can be calculated using the formula for probability of independent events:

P(choosing 2 red shirts) = P(choosing 1st red shirt) × P(choosing 2nd red shirt after 1st red shirt has been removed)

The probability of choosing the first red shirt is 3/15 (since there are a total of 15 shirts in the box, of which 3 are red).

After one red shirt is removed, there will be 2 red shirts and 14 shirts remaining in the box.

Therefore, the probability of choosing the second red shirt is 2/14.

P(choosing 2 red shirts) = (3/15) * (2/14) = 1/35

Therefore, the probability that Ned will choose 2 red shirts randomly from the box is 1/35.

Answer:

See below :)

Step-by-step explanation:

If you want a missing angle or side in one pair, and you have at least one side and angle pair, use the sine rule.

If you want a remaining side, and you have the other two sides and the angle opposite the unknown side, use the cosine rule.

If you want an angle, and you have all three sides, use the cosine rule rearranged for angles.

Step-by-step explanation:

Surface area of rectangular prism:

Here, area of the top of the prism is not included.

l = 24 in ; b = 20 in ; h = 16 in

Surface area = lb + 2bh + 2lh

                    = 24 * 20 + 2*20*16 + 2*24 *16

                    = 480 + 640 + 768

                    = 1888 sqaure inches

Surface area of triangular prism:

length = 24 in ; a = b = 16 in  ;  base = 20 in and height = 13 in

[tex]\sf \text{Base area=$2*\dfrac{1}{2}*base *height = base *height$}[/tex]

                = 20 * 13

                  = 260 square inches

Surface area = length*(a +b) + base area

                     = 24*(16+16) + 260

                     = 24 * 32 + 260

                      = 768 + 260

                      = 1028 square inches

Surface area of composite figure = 1888 + 1028

                                                          = 2916 square inches

Answer:

-9/25, -0.bar 3, √24, 4.92

Answer:

[tex]-\frac{9}{25} < -0.3 < \sqrt{24} < 4.92[/tex]

Step-by-step explanation:

We first have to expand -0.3, -9/25, and sqrt(24). Then we determine which is least and which is greater.

-0.3 = -0.3333...
-9/25 = -0.36

[tex]\sqrt{24}[/tex] ≈ 4.8989799486

4.92

[tex]-\frac{9}{25} < -0.3 < \sqrt{24} < 4.92[/tex]

The line which is parallel to the line 2x + 5y =8 is  [tex]y= -\frac{2}{5} x+4[/tex]  .

The correct option is (B) [tex]y= -\frac{2}{5} x+4[/tex]

If the lines are parallel, there is no solution for the pair of linear equations. If there is no solution of the given pair of linear equations, the equations are called inconsistent.

As we know the condition for two parallel line given by the equation

[tex]a_1 x+b_1y+c_1=0\\a_2x+b_2y+c_2= 0[/tex]

is:

[tex]\frac{a_1}{a_2} \; = \; \frac{b_1}{b_2}[/tex]  ≠ [tex]\frac{c_1}{c_2}[/tex]

We have the given equation as 2x + 5y =8

the equation which is parallel to 2x + 5y= 8 be

B)  [tex]y= -\frac{2}{5} x+4[/tex]

5y = -2x +20

2x+5y=20

So, it satisfies the condition [tex]\frac{a_1}{a_2} \; = \; \frac{b_1}{b_2}[/tex]  ≠ [tex]\frac{c_1}{c_2}[/tex]

Rest of the equation aren't  satisfying  the condition   [tex]\frac{a_1}{a_2} \; = \; \frac{b_1}{b_2}[/tex]  ≠ [tex]\frac{c_1}{c_2}[/tex].

Hence the line parallel to 2x+ 5y =8 is  [tex]y= -\frac{2}{5} x+4[/tex].

Answer:

13

Step-by-step explanation:

2 + 4 + 6 + 8 + ...... + 26

n = 13

Sum of first 'n' even numbers = n( n +1)

                                                 = 13 * 14

                                                  = 182

1 + 3 + 5 + 7 + .....+25

n = 13

Sum of first 'n' odd numbers = n²

                                               = 13 * 13

                                               = 169

2 + 4 + 6 + 8 + ... + 26 - (1 + 3 + 5 + 7 + ......+25) = 182 - 169

Answer:

9   23   23

Step-by-step explanation:

Two sides are equal    and are  each   2x + 5    ( x = third side)

add the three sides to get 55 inches

2x + 5     +     2x+5     +  x   = 55

5x = 45

x = 9                so the sides are  9   and 23   and 23

Answer:

x = 5

Step-by-step explanation:

Well all you have to do is use this formula

75 + 36x -3 = 180

How did I figure that out?? Well I know that the angle next to 75 is the same as 36x-3 becuase that are alternate interior angles and 75 and 36x-3 would be a linear pair meaning that the product of the them would be 180, Thus making the formula

Now all you have to do is combine like terms:

75 -3 = 72

72 + 36x = 180

subtract 72 from both sides

72 -72 = 0

180- 72 = 108

36x = 108

divide both sides by 36

X= 5

How much overtime pay do you get for working 40 hours if you get the following pay scale:

8.25 for all hours up to 40

110 for all hours in excess of 40

Calculate Total Pay

Total Wages = Regular Rate x 40 Hours + Overtime Rate x (Hours - 40)

Total Wages = 8.25 x 40 Hours + 110 x (40 - 40) Hours

Total Wages = 8.25 x 40 Hours + 110 x (0) Hours

Total Wages = 330 + 0

Total Wages = 330.00
