The mean absolute deviation of the data set is 2.5.  

It is defined as the measure to show the variation in data set in other words between the mean and every data value, the distance known as the MAD.

Given data:

10, 8, 10, 6, 6, 2, 10, 4

Using mean absolute deviation formula:

MAD = ∑ (xi - x)/n

So,

X = (10+8+10+6+6+2+10+4)/9

X = 56/8 = 7

Now, substituting the values in MAD formula

MAD = 20/8

MAD = 2.5

Hence, the mean absolute deviation of the data set is 2.5.

Step-by-step explanation:

The probability that a randomly selected carton has a puncture or a smashed corner is 0.05. This means that 5% of the cartons produced by the company will have either a puncture or a smashed corner.

To find the probability that a randomly selected carton has a puncture or a smashed corner, we can use the principle of inclusion-exclusion.

Let's denote the probability of a puncture as P(P), the probability of a smashed corner as P(S), and the probability of both a puncture and a smashed corner as P(P ∩ S).

Given:

P(P) = 10% = 0.10

P(S) = 8% = 0.08

P(P ∩ S) = 13% = 0.13

We can calculate the probability of a puncture or a smashed corner using the formula:

P(P ∪ S) = P(P) + P(S) - P(P ∩ S)

Substituting the values:

P(P ∪ S) = 0.10 + 0.08 - 0.13

Calculating:

P(P ∪ S) = 0.18 - 0.13

P(P ∪ S) = 0.05

Therefore, the probability that a randomly selected carton has a puncture or a smashed corner is 0.05.

The statement "the standard deviation is equal to the square of the variance" is False.

In statistics, both the standard deviation and the variance are measures of variability or dispersion within a dataset.

However, they are distinct measures and not equal to each other.

The variance (σ²) is the average of the squared deviations from the mean.

It is calculated by summing the squared differences between each data point and the mean, and then dividing by the total number of data points. The variance is expressed in squared units of the original data.

On the other hand, the standard deviation (σ) is the square root of the variance.

It represents the average amount of deviation or dispersion of data points from the mean.

By taking the square root of the variance, the standard deviation is expressed in the same units as the original data, making it more interpretable and easier to compare across different datasets.

In summary, the standard deviation is not equal to the square of the variance. Rather, it is the square root of the variance.

Answer:

a) Guadalupe pagó $ 86.8 por 15.5 metros de encaje blanco.

b) Guadalupe tendría que pagar $ 41.8 por 4.75 metros de cinta azul, entonces, no le alcanzaría el dinero para comprarle eso. Tendría un déficit de $ 1.8.

Step-by-step explanation:

a) Tras una lectura cuidadosa al enunciado, establecemos que el coste total pagado por Guadalupe es el producto de metraje comprado (\(n\)), medido en metros, y el coste unitario (\(c\)), medido en pesos por metro:

\(C = c\cdot n\) (Eq. 1)

Si conocemos que \(c = 5.60\,\frac{\$}{m}\) y \(n = 15.5\,m\), entonces tenemos que:

\(C = \left(5.60\,\frac{\$}{m}\right)\cdot (15.5\,m)\)

\(C = \$ \,86.8\)

Guadalupe pagó $ 86.8 por 15.5 metros de encaje blanco.

b) El coste total de la cinta azul es: (\(c = 8.80\,\frac{\$}{m}\), \(n = 4.75\,m\))

\(C = \left(8.80\,\frac{\$}{m} \right)\cdot (4.75\,m)\)

\(C = \$\,41.8\)

Guadalupe tendría que pagar $ 41.8 por 4.75 metros de cinta azul, entonces, no le alcanzaría el dinero para comprarle eso. Tendría un déficit de $ 1.8.

Answer:

Slope=1.000/2.000=0.500

b-i

q-i

b-(2*q+6)=0

Step-by-step explanation:

1.1     Solve   b-2q-6  = 0

Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).

"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.

In this formula :

y tells us how far up the line goes

x tells us how far along

m is the Slope or Gradient i.e. how steep the line is

b is the Y-intercept i.e. where the line crosses the Y axis

The X and Y intercepts and the Slope are called the line properties. We shall now graph the line  b-2q-6  = 0 and calculate its properties

Notice that when b = 0 the value of q is 3/-1 so this line "cuts" the q axis at q=-3.00000

 q-intercept = 6/-2 = 3/-1  = -3.00000

When q = 0 the value of b is 6/1 Our line therefore "cuts" the b axis at b= 6.00000

 b-intercept = 6/1  =  6.00000

Slope is defined as the change in q divided by the change in b. We note that for b=0, the value of q is -3.000 and for b=2.000, the value of q is -2.000. So, for a change of 2.000 in b (The change in b is sometimes referred to as "RUN") we get a change of -2.000 - (-3.000) = 1.000 in q. (The change in q is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)

   Slope     =  1.000/2.000 =  0.500

 Slope = 1.000/2.000 = 0.500

 b-intercept = 6/1 = 6.00000

 q-intercept = 6/-2 = 3/-1 = -3.00000

We cannot proceed with the calculation of the volume of the rectangular prism with a length of 5.6 units. To determine the volume accurately, we need additional information about the width and height of the prism.

Using the correct answer from part b, which states that the interval [0, 8] contains viable completion times of machine 1, we can calculate the volume of a rectangular prism with a length of 5.6 units.

To calculate the volume of a rectangular prism, we need to know its length, width, and height. However, the width and height of the prism are not provided in the question. Without these dimensions, it is not possible to determine the volume of the rectangular prism accurately.

The volume of a rectangular prism is calculated by multiplying its length, width, and height. In this case, we are only given the length of 5.6 units. To calculate the volume, we require the values of the width and height as well.

If the width and height are provided, we can multiply them by the length to obtain the volume of the rectangular prism. For example, if the width is 3 units and the height is 2 units, the volume would be calculated as follows:

Volume = Length x Width x Height

Volume = 5.6 units x 3 units x 2 units

Volume = 33.6 cubic units

However, without the dimensions of the width and height, we cannot proceed with the calculation of the volume of the rectangular prism with a length of 5.6 units. To determine the volume accurately, we need additional information about the width and height of the prism.

Using ratio-proportion method converted weight : 135 pounds = 61.4 kg.

Metric System Conversions Metric system is a system of measurement that uses the meter, liter, and gram as base units of length (distance), capacity (volume), and weight (mass) respectively.

These base units can be used in various combinations to derive larger or smaller units.

The following are the metric prefixes that you can use in conversions: Tera, giga, mega, kilo, hecto, deka, deci, centi, milli, micro, nano, pico.

The metric system conversions involves moving the decimal point to the left or right, and adding zeros where necessary.

You need to memorize the relation of one unit of measure to another.

For example, 1 kilometer = 1000 meters, 1 meter = 1000 millimeters, and 1 millimeter = 1000 picometers.

Fluids are usually measured in ounces, teaspoons, and tablespoons, as well as household measures, which are exceptions to using the metric system today. 1 fluid ounce is equal to 30 mL, and 1 quart is equal to 946 mL.

Weight is also an exception, with scales that often give weights in pounds. 1 kilogram is equal to 2.2 pounds.

Thus, to convert weight measurements, use ratio-proportion.In converting 135 pounds to kg, we use ratio-proportion as follows:

2.2 pounds = 1 kg

135 pounds = x kg

Cross-multiplying the ratio-proportion, we have:

2.2 × x = 135

Simplifying, we get:

x = 135 ÷ 2.2

x = 61.36 kg, which can be rounded to 61.4 kg.

Thus, 135 pounds is equal to 61.4 kg.

The provided questions cover various aspects of a 2-period production economy, including the household's problem, firm's problem, market clearing conditions, Social Planner's Problem, competitive equilibrium, and welfare theorems.

(a) The Household's problem is to maximize its utility over two periods subject to its budget constraint. The household's problem can be formulated as follows:

Max U(Co, C1) = log(Co) + ß log(C1)

subject to the budget constraint:

Co + (1+r)C1 ≤ (1+r)Ko + W0 + W1,

where Co and C1 are consumption in period 0 and 1 respectively, ß is the discount factor, r is the interest rate, Ko is the initial capital endowment, W0 and W1 are the wages in periods 0 and 1 respectively.

(b) The Firm's problem is to maximize its profit by choosing the optimal combination of capital and labor. The firm's problem can be formulated as follows:

Maximize F(K, L) - RK - WL,

where F(K, L) is the production function, K is capital, L is labor, R is the rental rate of capital, and W is the wage rate.

(c) The market clearing conditions are:

Capital market clearing: K1 = (1 - δ)K0 + S - C0, where δ is the depreciation rate, S is savings, and C0 is consumption in period 0.

Labor market clearing: L = L0 + L1, where L0 and L1 are labor supplies in periods 0 and 1 respectively.

(d) The Social Planner's Problem is to maximize social welfare, which is the sum of the household's utility and the firm's profit. The Social Planner's Problem can be formulated as follows:

Maximize U(C0, C1) + F(K, L) - RK - WL,

subject to the production function F(K, L) and the market clearing conditions.

(e) A Competitive Equilibrium is a situation where all markets clear and agents (household and firm) make optimal decisions based on prices and market conditions. It is characterized by the following conditions:

Household's problem is solved optimally.

Firm's problem is solved optimally.

Market clearing conditions hold.

(f) To solve the Social Planner's Problem, we need to set up the Lagrangian and solve for the optimal values of consumption, capital, and labor. The Lagrangian can be written as:

L = U(C0, C1) + F(K, L) - RK - WL + λ1[(1+r)K0 + W0 + W1 - Co - (1+r)C1] + λ2[K1 - (1 - δ)K0 + S - C0] + λ3[L - L0 - L1],

where λ1, λ2, and λ3 are the Lagrange multipliers.

(g) To solve the Competitive Equilibrium, we need to determine the prices of capital (R) and labor (W) that clear the markets. This can be done by equating the demand and supply of capital and labor, and solving the resulting equations.

(h) The First Welfare Theorem states that under certain conditions, a competitive equilibrium is Pareto efficient. It implies that a competitive equilibrium is a socially optimal allocation of resources. To verify the theorem, we need to demonstrate that the competitive equilibrium allocation is Pareto efficient.

(i) The Second Welfare Theorem states that any Pareto efficient allocation can be achieved as a competitive equilibrium with appropriate redistribution of initial endowments.

To verify the theorem, we need to show that given an initial Pareto efficient allocation, we can find prices and redistribution of endowments that lead to a competitive equilibrium that achieves the same allocation.

Answer: I not super sure, but I think you are supposed to put the equations on each side of the table. Your end result should be 2x to the second -5x-3.

Step-by-step explanation:

The equation 2x^2 - 9x^2y^2z^2 = 3 in cylindrical coordinates is 2r^2 * cos^2(θ) - 9r^4 * cos^2(θ) * sin^2(θ) * z^2 = 3 and the equation z = 7x^2 - 7y^2 in cylindrical coordinates is z = 7r^2 * cos^2(θ) - 7r^2 * sin^2(θ).

The cylindrical coordinate system uses three parameters: radius (r), azimuthal angle (θ), and height (z). To convert from Cartesian coordinates (x, y, z) to cylindrical coordinates (r, θ, z), we use the following relations:

x = r * cos(θ)
y = r * sin(θ)
z = z

(a) 2x^2 - 9x^2y^2z^2 = 3
Replace x and y with their cylindrical counterparts:

2(r * cos(θ))^2 - 9(r * cos(θ))^2(r * sin(θ))^2z^2 = 3

Simplify the equation:

2r^2 * cos^2(θ) - 9r^4 * cos^2(θ) * sin^2(θ) * z^2 = 3

This is the equation 2x^2 - 9x^2y^2z^2 = 3 in cylindrical coordinates.

(b) z = 7x^2 - 7y^2
Replace x and y with their cylindrical counterparts:

z = 7(r * cos(θ))^2 - 7(r * sin(θ))^2

Simplify the equation:

z = 7r^2 * cos^2(θ) - 7r^2 * sin^2(θ)

This is the equation z = 7x^2 - 7y^2 in cylindrical coordinates.

Queremos encontrar el valor de x (positivo), tal que esa expresión sea igual a cero, entonces tenemos que resolver:

9*x^2 - 80*x - 100 = 0.

Para ello podemos recordar la ecuación de Bhaskara, que para una ecuación de la forma:

Las soluciones son:

\(x = \frac{-b +-\sqrt{b^2 - 4*a*c} }{2a}\)

a = 9

b = -80

c = -100

Entoces, las soluciones van a ser:

\(x = \frac{-(-80) +- \sqrt{(-80)^2 - 4*9*(-100)} }{2*9} = \frac{80 +- 100}{18}\)

Entonces las dos soluciones son:

x = (80 - 100)/18 = -20/18 = -10/9
