1. Optimal strategy for solving this problem would be to feel for the socks, and grab two socks of the same color at random, as they have a 50% chance of being a match.

2. The total number of different ways they could be combined in pairs, assuming all 20 socks are different colors, is calculated by using the formula (nCr) = n! / (r! * (n-r)!)

So, the total number of different ways they could be combined in pairs would be (20*19)/2 = 190.

3. The total number of different ways they could be combined in pairs would be 10, as there are 10 black and 10 white socks, and they can only be paired with one another.

Answer:

First let 'A' stand for area.

So, there's 3 areas so we write it like this:

A1: 14 ft × 3ft = 42 ft

A2: (14 ft - 2 ft) × 2 ft = 24 ft

A3: 8 ft × 3 ft = 24 ft

So when you add all of them = 90 ft

The measure of the numbered angles of the quadrilaterals in the question are presented as follows;

14. m∠1 = 54°, m∠2 = 36°, m∠3 = 54° m∠4 = 108°, m∠5 = 72°

15. m∠1 = 90°, m∠2 = 45°, m∠3 = 45°, m∠4 = 45°, m∠5 = 45°

16. m∠1 = 64°, m∠2 = 64°, m∠3 = 26°, m∠4 = 90°, m∠5 = 64°

A quadrilateral is a four sided polygon.

14. The figure is a rectangle

The two diagonals of a rectangle are the same length and the diagonals of a rectangle bisect each other, therefore;

The triangles formed by the diagonals of the rectangle are isosceles triangles.

The angle at the vertex of the isosceles triangle that has 36° as the base angle of the triangle is therefore; (180° - 2 × 36°) = 108°

The angle ∠4, is a vertical angle to the angle calculated above, therefore;

m∠4 = 108°

m∠5 = (360° - 2 × 108°) = 72°

m∠5 = 72°

The similar triangles formed by the diagonals indicates that we get;

m∠2 = 36°

m∠1 = (180° - m∠5)/2

Therefore; m∠1 = (180° - 72°)/2 = 54°

m∠1 = 54°

∠1 ≅ ∠3

Therefore; m∠3 = m∠1 = 54°

m∠3 = 54°

15. The quadrilateral is a square, therefore;

The diagonals bisect each other and are perpendicular.

m∠1 = 90° (Definition of perpendicular angles)

m∠5 = (180° - 90°)/2 = 45°

m∠5 = 45°

∠3 ≅ ∠5, therefore;

m∠3 = m∠5 = 45°

m∠3 = 45°

m∠3 + m∠2 = 90° (The vertex angles of a square are 90°)

m∠2 = 90° - m∠3

m∠2 = 90° - 45° = 45° (Substitution property)

m∠2 = 45°

16. The quadrilateral is a rhombus, therefore;

The diagonals of a rhombus perpendicular

Adjacent angles are supplementary

The opposite angles of a rhombus are congruent

The opposite sides of a rhombus are parallel

Diagonals of a rhombus bisect the interior angles

The above properties indicates that we get;

90° + m∠1 + 26° = 180°

m∠1 = 180° - 26° - 90° = 64°

m∠1 = 64°

m∠4 = 90°

The angle ∠3 and the 26° angle are alternate interior angles. Alternate interior angles between parallel lines are congruent, therefore;

m∠3 = 26°

m∠1 = m∠2 (definition of bisected angle), therefore;

m∠2 = m∠1 = 64°

m∠2 = 64°

∠2 and ∠5 are alternate interior angles, therefore;

∠2 ≅ ∠5

m∠5 = m∠2 = 64°

m∠5 = 64°

Answer:

460

Step-by-step explanation:

Let b = base speed and w = wind power.

Here's what we know:

b + w = 490

b - w = 430

From here, we can use the elimination method. If we treat each variable and constant as columns, we do the following:

b + b = 2b

w - w = 0

490 + 430 = 920

Leaving us with:

2b = 920

Divide by 2:

2b / 2 = b

920 / 2 = 460

So b = 460 mph

The total distance that rob ran and walked for 60 minutes is; 8820 meters

The parameter for the constant speed is that Rob runs at a speed of 3.4 meters per second for one half hour.​ Thus;

V1 = 3.4 m/s

t1 = 1.5 hours =

30 * 60 = 1,800 seconds.

The distance he runs at that speed and time is;

S1 = V1 * t1

He walks at V2 = 1.5 m/s for t2 = 1,800 seconds.

The distance he walks;

S2 = V2 * t2

Answer: You want to ship 80 items, and each case holds 7 items. To find the number of cases needed to ship the 80 items, you can use the formula:

Number of cases = (Number of items) / (Items per case)

So in this case, the number of cases needed to ship 80 items is:

Number of cases = 80 / 7

Which simplifies to 11.428571428571429, so you will need 12 cases to ship 80 items.

The value of `near twentyfive` is approximately equal to 25.3 and is calculated by taking the square root of the product of `e` raised to the power of[tex]$2\pi$[/tex], and 30[tex]$\pi$[/tex].

The designation "e" for the natural logarithm's base, which is around 2.71, is provided by the math module. We must take the square root of the product of "e" raised to the power of $2 pi and of "30 pi" in order to determine the value of "near twentyfive." The mathematical notation for this is sqrt(e(2)pi, pi). 'near twentyfive' has a value that is roughly equivalent to 25.3. This is due to the fact that $e2pi$ is roughly equivalent to 19.7, and $30pi$ is roughly equivalent to 94.2. 1867.4 is the result of adding these two integers together, while 43.4 is the result of taking 1867.4 as its square root. Finally, when 43.4 is divided by 2, the result is 25.3

A negative correlation coefficient indicates that as one variable increases, the other variable decreases. This means that the points on the scatterplot are spread in a downward direction, which suggests a negative correlation between the two variables.

A scatterplot is a graph that shows the relationship between two variables by plotting points that represent the values of the two variables. When reviewing a scatterplot, one can look for the correlation coefficient, which is a statistical measure that describes the strength of the relationship between the two variables. A negative correlation coefficient indicates that as one variable increases, the other variable decreases. This means that the points on the scatterplot are spread in a downward direction, which suggests a negative correlation between the two variables. A scatterplot with several negative coefficients indicates that the correlation between the two variables is negative, meaning that when one variable increases, the other one decreases. The strength of the correlation is determined by how close the points on the scatterplot are to the line of best fit. A strong negative correlation means that the points are close to the line of best fit and are spread in a downward direction, while a weak negative correlation means that the points are further away from the line of best fit and are spread in a more random pattern.

As per the interpolation method, the proportion of orders that are processed in less than 240 seconds is 0.17

The interpolation method is defined as a method of deriving a simple function from the given discrete data set such that the function passes through the provided data points.

Here we have given that at a small coffee shop, the distribution of the number of seconds it takes for a cashier to process an order is approximately normal with mean 276 seconds and standard deviation 38 seconds.

And the proportion of orders that are processed in less than 240 seconds is calculated as,

Here we know that 1 standard deviation below mean = 16% = M - d

Then we apply the value on it, then we get,

=> 276 s - 38 s = 238 s

Here we know that the mean of distribution is,

=> 50% which is equal to 276 s

And the proportion less than 240 s is consider that x%, then by using the interpolation method it can be calculated as,

=> (240 - 238) / (276 - 238) = (x - 16) / (50 - 16)

When we simplify this one then we get,

=> 1/19 = x - 16 / 34

Which can be rewritten as,

=> 19(x - 16)  = 34

=> 19x - 304 = 34

=> 19x = 338

=> x = 17.78%.

Therefore the closest to the proportion of orders that are processed in less than 240 seconds is 17% that is equal to the value of 0.17.

h(x) = g(x) + 200, which means the average  new income tax is the sum of the original income tax and an additional flat fee of 200 dollars per taxpayer.

h(x) = g(x) + 200

h(x) is the new income tax for a single person with taxable income x dollars.

g(x) is the 2010 federal income tax for a single person with taxable income x dollars.

Therefore, h(x) = g(x) + 200, which means the new income tax is the sum of the original income tax and an additional flat fee of 200 dollars per taxpayer.

The new income tax plan consists of the 2010 income tax plus an additional 200 dollars per taxpayer. To represent this mathematically, we let g(x) be the function such that g(x) is the 2010 federal income tax for a single person with taxable income x dollars, and let h(x) be the corresponding function for the new income tax plan. By examining the new income tax plan, we can see that the new income tax is the sum of the original income tax plus an additional flat fee of 200 dollars per taxpayer. Thus, h(x) = g(x) + 200, which is a concise formula that captures the essence of the new income tax plan. This formula shows that the new income tax is simply the original income tax increased by a fixed amount of 200 dollars.
