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: the answer is Math and i took the test

Answer:D

Step-by-step explanation:

The slope of a line will be 1/6. Then the correct option is D.

The slope is the ratio of rising or falling and running. The difference between the ordinate is called rise or fall and the difference between the abscissa is called run.

Slope = (y₂ - y₁) / (x₂ - x₁)

The points are given below.

(-6,3) and (12,6)

(x₁, y₁) = (-6,3)

(x₂, y₂) = (12,6)

Then the slope of a line will be

Slope = (6 – 3) / (12 + 6)

Slope = 3 / 18

Slope = 1/6

Then the correct option is D.

Answer:

x = 19.9

Step-by-step explanation:

These kinds of problems have a specific formula.

Formula: outside (whole) = outside (whole)

We could substitute our variables into this.

For the first line, our outside segment is b and the whole thing is a + b

For the second line, our outside segment is x, and the whole thing is x.

[tex]b (a+b) = x(x)\\11 (25+11) = x^2\\11 (36) = x^2\\396 = x^2\\\\x=\sqrt{396}[/tex]

The [tex]\sqrt{396}[/tex] = 19.8997487421

Rounding to the nearest tenth, your answer is 19.9

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

                                                                            = 13

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.

Answer: 4 toys

Step-by-step explanation:

     We will multiply 3 by 30 for how many toys he can currently put into boxes.

3 * 30 = 90

     Now we will subtract this from the total number of toys for our answer.

94 - 90 = 4

          There are 4 toys left.

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

Answer:

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

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
