The probability that exactly 2 people are left handed if 11% people are left handed and 5 are selected at random is 100.

Probability is a method with the help of which we chose a particular object on random from many given objects.

P(E) = no of favorable outcomes/total number of outcomes

Let there are 100 people

11% are left handed = 11% of 100 = 11

5 are selected randomly.

No of favorable outcomes = 5

Total no of outcomes = 11

Hence, the probability that people selected are left handed is 5/11

Answer:

y = 2/3x + 2

Step-by-step explanation:

Slope is m = 2/3

x-intercept has coordinate (-3,0)

Slope-intercept: y = mx + b

0 = 2/3(-3) + b

0 = -2 + b

b = 2

then y = 2/3x + 2

Using linear equations, Sarah needs to utilize 79.745 pounds of the premium beans.

Let X= the weight of premium beans (lbs)

Let Y=weight of less expensive beans (lbs)

Sarah wants to create 170lbs of coffee in total to sell, thus the weight of the more expensive beans and the less expensive beans must add up to the same total.

X + Y = 170 [1]

The cost of a pound of mixed coffee will be determined by multiplying the cost of the premium beans by the weight of those beans added to the mixture, as well as the cost of the less expensive beans by the weight of those beans added to the combination. This must equal $170 pounds multiplied by $3.79 per pound:

5.25*X + 2.50 *Y = 644.3 [2]

Solve the system of linear equations after that.

Divide equation (1) by 2.5 dollars:

2.50X + 2.50Y = 425 [3]

Eq. [3] minus equation [2] equals:

5.25X - 2.50X +2.50Y - 2.50Y = 644.3- 425

2.75X= 219.3

X= 79.745 lbs

Answer:

70: 1, 2, 5, 7, 10, 14, 35, 70

Step-by-step explanation:

Answer: A line has one dimension because it is made up of a figure with no thiknes that extends infinitely in both directions.

Step-by-step explanation:

A line is a one-dimensional figure, it has no thickness.

For reference,  point is zero dimesional, a plane is twodimensional.

Then the correct answer would be:

A line has one dimension because it is made up of a figure with no thiknes that extends infinitely in both directions.

Part A:The given line has a slope of -1/4. Therefore, the slope of the line perpendicular to it would be the negative reciprocal of -1/4, which is 4.We know that the line passes through the point (2,-1). We can use the point-slope form of the equation to find the equation of the line:y - (-1) = 4(x - 2)

y + 1 = 4x - 8

y = 4x - 9So the equation of the line that is perpendicular to y=-1/4x+5 and passing through the point (2,-1) is y = 4x - 9 in point-slope form.Part B:To determine if the point (3,3) lies on the line, we can substitute x = 3 and y = 3 into the equation we found in Part A:y = 4x - 9

3 = 4(3) - 9

3 = 3Since the equation is true, the point (3,3) lies on the line y = 4x - 9.

Answer:

Part A:

To find the equation of a line that is perpendicular to another line, we need to know that the slopes of the two lines are negative reciprocals of each other. The given line has a slope of -1/4, so the slope of the perpendicular line will be 4.

Using the point-slope form of a line, we can write the equation of the line as:

y - (-1) = 4(x - 2)

Simplifying this equation, we get:

y + 1 = 4x - 8

y = 4x - 9

Therefore, the equation of the line that is perpendicular to the line y=-1/4x+5 and passing through the point (2,-1) is y=4x-9, written in point-slope form.

Part B:

To check if the point (3,3) lies on the line y=4x-9, we can substitute x=3 and y=3 into the equation and see if it is a true statement:

y = 4x - 9

3 = 4(3) - 9

3 = 3

This is not a true statement, since 3 does not equal 0. Therefore, the point (3,3) does not lie on the line y=4x-9.

The width of the flooring room is 50m.

The cost of flooring the room is Rs. 56,000.

The rate of flooring in the room is Rs. 14 per sqm.

The Dodd-Frank Act has been criticized for a variety of reasons, and the most common ones are as follows

The Dodd-Frank Act was signed into law in 2010 by President Barack Obama. It was implemented as a reaction to the financial meltdown of 2008-2009. It consists of 2,300 pages of rules and regulations aimed at regulating and restricting the activities of financial organizations. The Dodd-Frank Act has been criticized for a variety of reasons, and the most common ones are as follows:

1.The burdensome and expensive certification documentationThe Dodd-Frank Act has created extensive certification procedures and requirements that must be met by banking and financial firms. This adds a significant financial burden to these organizations, and it's claimed that this cost is passed on to the customers, ultimately affecting their welfare.

2. The threat of government overreachThe Dodd-Frank Act empowered the government with extensive regulatory and enforcement authority over the financial sector. This is seen as a threat by many, as it can result in the government exerting undue influence over financial firms, ultimately leading to a less efficient and less competitive market.

3. Lack of real legal ability to influence financial marketsCritics of the Dodd-Frank Act claim that it has not had a real impact on the financial market. They claim that the rules and regulations are either ignored by financial firms or not enforced by regulators, ultimately rendering the Dodd-Frank Act ineffective.

4. Continuing presence of redlining in urban and minority areasThe Dodd-Frank Act was enacted to prevent the occurrence of financial discrimination, particularly in urban and minority areas. Critics of the Act claim that it has not been successful in eradicating this issue, and redlining continues to persist.

Therefore, the correct options that answer the question are: 1, 2, 3, and 4. It is important to note that while the Dodd-Frank Act has been subject to criticism, it is still considered a landmark piece of legislation that has improved the safety and stability of the financial sector.

Answer:

x = 3/5

Step-by-step explanation:

This equation can be solved with algebraic techniques. We will simplify the equation by combining like terms and then use algebraic techniques in order to solve for x.

2(x - 4) + 2x = -6x - 2 Use the distributive property.

2x - 8 + 2x = -6x - 2 Combine like terms (variable terms first).

4x - 8 = -6x - 2 Add 6x to both sides of the equation.

There are three suit jackets and three shirts. To find the probability of randomly selecting a suit jacket and a shirt that are the same color, we need to count the number of pairs that have the same color and divide it by the total number of possible pairs.

There are three possible colors to choose from, so we can consider each color separately:

Black: There is one black suit jacket and one black shirt. The probability of selecting a black suit jacket and a black shirt is (1/3) x (1/3) = 1/9.

Green: There is one green suit jacket and no green shirts. It is impossible to select a green suit jacket and a green shirt, so the probability is 0.

White: There is one white suit jacket and one white shirt. The probability of selecting a white suit jacket and a white shirt is (1/3) x (1/3) = 1/9.

Blue: There are no blue suit jackets and one blue shirt. It is impossible to select a blue suit jacket and a blue shirt, so the probability is 0.

Adding up the probabilities from each color, we get:

1/9 + 0 + 1/9 + 0 = 2/9

So the probability of Ricardo randomly selecting a suit jacket and a shirt that are the same color is 2/9.

The height and radius of the cone with maximal volume V and surface area S = 8 are h = (4/(3π^2))^(1/4) and r = (1/(3π^2))^(1/4),

respectively.Explanation: To find the height and radius of the cone with maximal volume and surface area of 8, we need to use the formulas for the surface area and volume of a right-circular cone in terms of r and h. We can then use the method of Lagrange multipliers to find the values of r and h that maximize the volume subject to the constraint that the surface area is equal to 8.Using the formulas for the surface area and volume of a cone, we get:S = πr √(r²+h²)V = 1/3πr²hWe can then set up the Lagrangian function L(r,h,λ) = 1/3πr²h + λ(πr √(r²+h²) - 8), where λ is the Lagrange multiplier.Taking the partial derivatives of L with respect to r, h, and λ and setting them equal to zero, we get:∂L/∂r = 2/3πrh + λ(π√(r²+h²) + r²/√(r²+h²)) = 0∂L/∂h = 1/3πr² + λ(πh/√(r²+h²)) = 0∂L/∂λ = πr √(r²+h²) - 8 = 0Solving these equations, we get:h = (4/(3π^2))^(1/4)r = (1/(3π^2))^(1/4)Therefore, the height and radius of the cone with maximal volume and surface area of 8 are h = (4/(3π^2))^(1/4) and r = (1/(3π^2))^(1/4), respectively.(b) The ratio of height to radius for the cone with minimal surface area S and volume V = 5 is h/r = √2.Explanation: Using the formulas for the surface area and volume of a cone in terms of r and h, we can set up the following optimization problem:Minimize S = πr √(r²+h²)Subject to V = 1/3πr²h = 5Using the method of Lagrange multipliers, we can set up the Lagrangian function L(r,h,λ) = πr √(r²+h²) + λ(1/3πr²h - 5), where λ is the Lagrange multiplier.Taking the partial derivatives of L with respect to r, h, and λ and setting them equal to zero, we get:∂L/∂r = π√(r²+h²) + 2λr/3πh = 0∂L/∂h = πr²h/√(r²+h²) - 5λ/3π = 0∂L/∂λ = 1/3πr²h - 5 = 0Solving these equations, we get:h/r = √2Therefore, the ratio of height to radius for the cone with minimal surface area S and volume V = 5 is h/r = √2.(c) No, a cone with given volume V and maximal surface area does not exist.Explanation: Using the formulas for the surface area and volume of a cone in terms of r and h, we can set up the following optimization problem:Maximize S = πr √(r²+h²)Subject to V = 1/3πr²hUsing the method of Lagrange multipliers, we can set up the Lagrangian function L(r,h,λ) = πr √(r²+h²) + λ(1/3πr²h - V), where λ is the Lagrange multiplier.Taking the partial derivatives of L with respect to r, h, and λ and setting them equal to zero, we get:∂L/∂r = π√(r²+h²) + 2λr/3πh = 0∂L/∂h = πr²h/√(r²+h²) - λ/3πr² = 0∂L/∂λ = 1/3πr²h - V = 0Solving these equations, we get:h = rr³ = 3V/πSubstituting h = r into the surface area formula, we get:S = 2

Answer:

If n is even, then n^2 + 8n + 20 is even.

Let n = 2k (k = 0, 1, 2,...). Then:

(2k)^2 + 8(2k) + 20 = 4k^2 + 16k + 20

= 4(k^2 + 4k + 5)

This expression is even for all k, so if n is even, this expression is even.

So if n^2 + 8n + 20 is odd, then n is odd.

Natural numbers n must be odd for n^2 + 8n + 20 to be odd.

To prove that if n^2 + 8n + 20 is odd, then n is odd for natural numbers n, we can use proof by contradiction.

Assume that n is even for some natural number n. Then we can write n as 2k for some natural number k.

Substituting 2k for n, we get:

n^2 + 8n + 20 = (2k)^2 + 8(2k) + 20
= 4k^2 + 16k + 20
= 4(k^2 + 4k + 5)

Since k^2 + 4k + 5 is an integer, we can write the expression as 4 times an integer. Therefore, n^2 + 8n + 20 is divisible by 4 and hence it is even.

But we are given that n^2 + 8n + 20 is odd. This contradicts our assumption that n is even.

Therefore, our assumption is false and we can conclude that n must be odd for n^2 + 8n + 20 to be odd.

In detail, we have shown that if n is even, then n^2 + 8n + 20 is even. This is a contradiction to the premise that n^2 + 8n + 20 is odd. Therefore, n must be odd for n^2 + 8n + 20 to be odd.
