To find the value of tan(-284°24'), we can use the fact that the tangent function has period π, which means that:

tan(x) = tan(x + nπ)

where n is any integer. We can use this fact to convert the angle -284°24' to an equivalent angle between 0° and 360°:

-284°24' = -360° + 75°36' = 75°36'

Now, we need to find the reference angle, which is the acute angle between the terminal side of the angle and the x-axis. Since 75°36' is in the second quadrant (where the tangent function is positive), the reference angle is:

75°36' - 180° = -104°24'

Finally, we can use the identity:

tan(-θ) = -tan(θ)

to find the value of tan(-104°24'):

tan(-104°24') = -tan(104°24')

We can use a calculator to find that:

tan(104°24') ≈ 2.3835

Therefore:

tan(-284°24') ≈ -2.3835 (rounded to the nearest ten-thousandth)

So, the value of tan(-284°24') to the nearest ten-thousandth is -2.3835.

The future value of Ted's investment after 30 years would be approximately $13,711.86.

What is statistics?

Statistics is a branch of mathematics that deals with the collection, analysis, interpretation, presentation, and organization of numerical data.

Ted can use the formula for the future value of an annuity to calculate the future value of his investment:

FV = Pmt x (([tex](1 + r)^{n}[/tex]) - 1) / r

Where:

FV = Future Value

Pmt = Payment per period (monthly in this case)

r = Interest rate per period (monthly in this case)

n = Number of periods (in this case, 30 x 12 = 360 months)

Substituting the given values, we get:

FV = $250 x (([tex](1 + 0.062/12)^{360}[/tex] - 1) / (0.062/12)

FV = $250 x (283.8576) / 0.0051667

FV = $13,711.86

Therefore, the future value of Ted's investment after 30 years would be approximately $13,711.86.

The probability of there being no defects in the entire shipment is 0.2075.

What is probability?

Probability can be used to calculate an event's probability. It can only be used to assess the possibility that an event will occur. A scale from 0 to 1, where 0 is impossible and 1 is a particular occurrence.

We are given that out of the 400 components, 68 are defective and 332 are non-defective computer components.

A random sample of 25 is taken.

So,

⇒ Probability (Defects in the shipment) =  [tex]\frac{68}{400}[/tex]

⇒ Probability (Defects in the shipment) = 0.17

Thus,

⇒ Probability (No Defects in the shipment) =25 * (1 - 0.17)

⇒ Probability ( No Defects in the shipment) = 25 * (0.83)

⇒ Probability ( No Defects in the shipment) = 0.2075

Hence, the probability of there being no defects in the entire shipment is 0.2075.

Given triangle is not a right angle triangle.

What is Pythagoras theorem?

For any right angle triangle,

Hypotenuse ²= Base²+Height ²

To determine whether the any triangle is a right triangle, we can use the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.

Let's denote the sides of the triangle as follows,

a = 14

b = 10

c = 4√19

Then we can check whether the Pythagorean theorem holds for these values:

c² = (4√19)² = 16×19 = 304

a²+ b² = 14²+ 10² = 196 + 100 = 296

Since c² is not equal to a² + b², the triangle is not a right triangle. Therefore, the answer is no, the given triangle is not a right angle triangle.

So

10+(6x2)=22

The 999th digit to the right of the decimal point is 9.

Decimal expansion is the representation of a number in decimal form. In decimal expansion, a number is represented using the base-ten positional notation system, where each digit represents a multiple of a power of ten.

For example, the decimal expansion of the number 1234.5678 is:

which simplifies to:

1000 + 200 + 30 + 4 + 0.5 + 0.06 + 0.007 + 0.0008 = 1234.5678

The decimal expansion of a number can be finite or infinite, and it may or may not be a repeating decimal. A repeating decimal is a decimal that has a repeating pattern of digits after the decimal point. For example, the decimal expansion of 1/3 is 0.3333..., with the digit 3 repeating infinitely.

To find the 999th digit to the right of the decimal point, we need to determine the repeating block of digits in the decimal expansion of 9/23.

The remainder when 9 is divided by 23 is 9, so we can start the long division as follows:

         0.3913043478260869565217...

         --------------------------------

23 |    9.00000000000000000000

           - 6

          --------

                30

               -23

               -----

                   7

                    ...

We can see that the decimal expansion of 9/23 repeats after 22 digits, since the remainder becomes 7, which is the same as the remainder we obtained after dividing 9 by 23.

Therefore, the 999th digit to the right of the decimal point is the same as the (999 mod 22)th digit, which is the 9th digit in the repeating block of digits:

0.3913043478260869565217...

9

So the 999th digit to the right of the decimal point is 9.

Therefore, the height of Figure 1 is 4.

Using the area formula, the length of the sides of the two squares are 22 cm and 25 cm respectively.

A square is a regular quadrilateral in Euclidean geometry, which means that it has four equal sides and four equal angles.

It can alternatively be explained as a rectangle with two neighboring sides that are of equal length.

The square's four sides are equal to one another or congruent.

The square's opposing sides run parallel to one another.

The square's diagonals form a 90° angle with one another.

The square's two diagonals are equal to one another.

Area: s²

s² + (s+3)² = 1017

s² + s² + 9 = 1017

2s² = 1017 - 9

2s² = 1,008

s² = 1008/2

s² = 504

s = ²504

s = 22.44

Round off: 22 cm

Then, (s+3) = 22 + 3 = 25 cm

150 men and 252 women

Step-by-step explanation:

            Men : Women = 5 : 9

Number of men = 5x

Number of women = 9x

42 women left the museum.

Number of remaining women = 9x - 42

              New ratio = 2 : 3

                      [tex]\dfrac{5x}{9x -42}=\dfrac{2}{3}\\\\\\\bf Cross \ multiply,[/tex]

                          3*5x  = 2*(9x - 42)

                          15x     = 2*9x - 2*42

                              15x = 18x - 84

                  18x - 84 = 15x

Add 84 to both the sides,

                         18x = 15x + 84

Subtract 15x from both sides,

                18x - 15x = 84

                         3x = 84

Divide both sides by 3,

                            x = 84 ÷ 3

                            x =  28

Number of men = 5 * 28 = 140

Number of women = 9*28 = 252

The value of y for the inverse variation when x = -12 is derived to be equal to 1.

Inverse variation is a mathematical relationship between two variables, in which an increase in one variable leads to a proportional decrease in the other variable. Mathematically, inverse variation can be expressed as y = k/x, where y and x are the two variables, k is a constant of proportionality, and the product of y and x is always equal to k.

when x = 6 and y = -2, then k is derived as:

-2 = k/6

k = -12 {cross multiplication}

Step-by-step explanation:

We can express the cost (y) as a linear function of heater quantity (x) by writing the equation in the slope-intercept form (y = mx + b), where m is the slope (in this case change in cost / change in heater quantity) and b is the y-intercept (when x = 0).

To find the slope (m), we can use the slope formula, which is

[tex]m=\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex], where x1 and y1 are one point and x2 and y2 are the other point.

If we allow (30, 7500) to represent x1 and y1 and (40, 9000) to represent x2 and y2, our slope is:

[tex]m=\frac{9000-7500}{40-30}\\ \\m=\frac{1500}{10}\\ \\m=150[/tex]

Now, we can find the y-intercept by plugging in the slope and one of the points and solving for b:
