Answer: 3:1

Step-by-step explanation:

The expected value of X is 7, and the standard deviation of X is 2.42 respectively.

The average of X's potential values is the expected value of X. We must first determine the sum of all potential x values multiplied by each value's associated probability before we can determine the expected value.

Calculate the expected value of X

Expected value = (2×(1/36)) + (3×(2/36)) + (4×(3/36)) + (5×(4/36)) + (6×(5/36)) + (7×(6/36)) + (8×(5/36)) + (9×(4/36)) + (10×(3/36)) + (11×(2/36)) + (12×(1/36))

Expected value = 7

Calculate the variance of X

Variance = (2-7)2×(1/36) + (3-7)2×(2/36) + (4-7)2×(3/36) + (5-7)2×(4/36) + (6-7)2×(5/36) + (7-7)2×(6/36) + (8-7)2×(5/36) + (9-7)2×(4/36) + (10-7)2×(3/36) + (11-7)2×(2/36) + (12-7)2×(1/36)

Variance = 5.83

Calculate the standard deviation of X

Standard deviation = √(variance)

Standard deviation = 2.42

The correct answer is (d) No, it is not continuous because lim x→3 f(x) ≠ lim x→3 f(x).

To determine if the function f(x) = (x+3)/(x²-9) is continuous at x=3, we need to check if the limit of the function exists as x approaches 3 from both the left and the right, and whether this limit is equal to the value of the function at x=3.

First, we can check the limit as x approaches 3 from the left:

lim x→3- f(x) = lim x→3- (x+3)/(x²-9) = (-3)/(0-) = ∞

Next, we can check the limit as x approaches 3 from the right:

lim x→3+ f(x) = lim x→3+ (x+3)/(x²-9) = (6)/(0+) = ∞

Since both one-sided limits are infinite, the limit as x approaches 3 does not exist.

Therefore, the function f(x) = (x+3)/(x²-9) is not continuous at x=3.

The correct answer is (d) No, it is not continuous because lim x→3 f(x) ≠ lim x→3 f(x).

For given triangle,  Length of XY and YZ is equal to 7√2.

What is a triangle's definition?

A triangle has three straight sides and three angles. It is one of the basic shapes in geometry and has many properties and applications in mathematics and everyday life. The sum of the interior angles of a triangle is always 180 degrees, and there are different types of triangles depending on their side lengths and angle measures and it includes 6 types of triangles.

Now,

If one of the angles of a right triangle is 90 degrees and another angle is 45 degrees, then the third angle must also be 45 degrees. This means that the triangle is a 45-45-90 triangle, which has a special property that the two legs are congruent and the hypotenuse is the square root of 2 times the square length of each leg.

In this case, the hypotenuse is given as 14, so we can set up the following equation:

14 = √2x²

where x is the length of each leg of the triangle. To solve for x, we can square both sides of the equation:

14² = 2x²

196 = 2x²

x² = 98

x = 7√2

So, each leg of the triangle has a length of 7√2, and the hypotenuse has a length of 14.

Hence,

             Length of XY and YZ is equal to 7√2.

Zip line B's total length requires 301 feet of cable using the distance between trees and change in height.

To determine the length of cable needed, we need to calculate the horizontal and vertical distances between the trees, and then apply the constraints.

Let's start by labeling the trees and their distances:

Tree 1: 120 ft from Tree 2, 150 ft from Tree 3

Tree 2: 140 ft from Tree 3

Zip line B is the longest, so calculate the length of cable needed for that option.

Horizontal distance: Tree 2 to Tree 3 is 140 ft.

Vertical distance: The starting platform needs to be 16 ft above the ground, and the harness hangs down 4 ft below the cable, plus an additional 3 ft for the rider's legs. So the total height difference is 16 + 4 + 3 = 23 ft.

Using the slope constraint, we want a vertical change of 6 to 8 feet for every 100 feet of horizontal change. For a horizontal distance of 140 ft, we want a vertical change of:

(6/100) x 140 = 8.4 ft

(8/100) x 140 = 11.2 ft

So the zip line needs to have a vertical drop of between 8.4 and 11.2 ft.

Using the slack constraint, we need to add 5% slack to the length of the cable:

140 ft x 1.05 = 147 ft

Adding 7 ft of extra cable at each end, the total length of cable needed is:

140 ft + 147 ft + 7 ft + 7 ft = 301 ft

Therefore, the total length of cable needed for Zip line B is 301 ft.

To express 1/4 as an equivalent fraction with a different denominator, we need to find a common multiple of 4 and the desired denominator.

Let's say we want to express 1/4 as an equivalent fraction with a denominator of 12. To do this, we can multiply both the numerator and denominator of 1/4 by 3, which gives us:

1/4 x 3/3 = 3/12

So 1/4 is equivalent to 3/12 when the denominator is 12.

In general, to express a fraction a/b as an equivalent fraction with a different denominator c, we can multiply both the numerator and denominator by the same value that makes b equal to c.

This is because when we multiply both the numerator and denominator by the same value, we are essentially multiplying the fraction by 1, which does not change its value.

For example, to express 2/5 as an equivalent fraction with a denominator of 15, we can multiply both the numerator and denominator by 3, which gives us:

2/5 x 3/3 = 6/15

Therefore, 2/5 is equivalent to 6/15 when the denominator is 15.

Answer:

So, the possible width of the banner would be 9 feet or less, since we have assumed a maximum total trim of 50 feet. If the width exceeds 9 feet, the total trim required would exceed the available trim of 50 feet. Therefore, the possible widths of the banner are 9 feet or less.

Step-by-step explanation:

Given:

Length of the banner (L) = 16 feet

Total trim available (T) = 50 feet

The perimeter of a rectangle is given by the formula:

Perimeter = 2 * (Length + Width)

In this case, the perimeter of the banner would be equal to the total trim available, since the trim goes all the way around the banner.

So, we can set up the equation as follows:

2 * (L + w) = T

Plugging in the given values:

2 * (16 + w) = 50

Simplifying the equation:

32 + 2w = 50

2w = 50 - 32

2w = 18

w = 18 / 2

w = 9

The equation of the parabola in vertex form is y = (1/4)x² - 6.

To write the equation of the parabola in vertex form, we use the formula:

y = a(x-h)² + k

Where (h,k) is the vertex and "a" is a constant that determines the shape of the parabola.

Given that;

The vertex is (0,-6)

Hence:

h = 0 and k = -6.

We can substitute these values into the formula to get:

y = a(x-h)² + k

y = a(x - 0)² - 6

y = ax² - 6

Now we need to find the value of "a". We are also given that the parabola passes through the point (-6,3).

x = -6 and y = 3

We can substitute this point into the equation to get:

y = a(x - h)² + k

3 = a( - 6)² - 6

3 = 36a - 6

9 = 36a

a = 1/4

Now we know the value of "a", we can substitute it back into the equation we derived earlier:

y = ax² - 6

y = (1/4)x² - 6

Therefore, the equation in vertex form is y = y = (1/4)x² - 6.

1. Chicken became the key product that drove the creation of the Interstate Highway System, which led to the dominance of American trucks in the US truck market.

2. A party may want to impose a tariff to protect domestic industries from foreign competition or to generate revenue for the government.

3. A party is usually trying to protect domestic industries, but a tariff on automobiles would hurt both domestic consumers who would pay higher prices and foreign producers who would face reduced demand.

4. Competition encourages innovation by providing incentives for companies to improve their products and services to stay ahead of their rivals; American trucks stayed the same because they faced little competition due to protectionist policies.

5. Foreign companies tried to get around American-imposed tariffs on automobiles by establishing factories in the US, forming joint ventures with American companies, or exporting through third countries.

6. The methods used to get around tariffs can be efficient in the short term, but they may not be sustainable or desirable in the long term as they can lead to trade imbalances and undermine the competitiveness of domestic industries.

7. Tariffs can be used as a bargaining chip to negotiate better trade deals, but they should be imposed judiciously and only as a last resort to avoid damaging the economy and harming consumers.

1. In the podcast, chicken is cited as the reason why American trucks dominate the truck market in the United States.

This is because in the 1960s, the government imposed regulations on the trucking industry that limited the amount of weight a truck could carry.

To get around these regulations, the industry started using smaller trucks to transport goods, which were often not strong enough to handle the weight.

However, they found that if they put chicken on the back of the trucks, the weight of the cargo would distribute more evenly and the smaller trucks could handle the load.

This led to the development of the modern pickup truck, which is now a staple of the American automobile market.

2. Parties may want to impose tariffs for various reasons, such as to protect domestic industries and jobs from foreign competition, to raise revenue for the government, or to level the playing field in international trade.

Two specific reasons for imposing tariffs could be to protect national security interests or to address unfair trade practices by other countries.

3. Tariffs are usually imposed to protect domestic industries and jobs, and the parties that are being protected are typically the producers of the goods or services in question.

However, tariffs can also harm consumers who may have to pay higher prices for imported goods or may have fewer choices in the marketplace. For example, if a tariff is imposed on automobiles, domestic car manufacturers may benefit, but consumers may have to pay more for cars, and foreign automakers may lose market share.

4. Competition encourages innovation by creating incentives for companies to improve their products or services to gain a competitive advantage.

In the case of American trucks, the lack of competition may have contributed to their lack of innovation over the years. Since they dominated the market, there was little pressure to improve or innovate, and as a result, they have largely stayed the same.

However, the rise of foreign competition in recent years has led American truck manufacturers to invest more in innovation to stay competitive.

5. Foreign companies have tried to get around American-imposed tariffs on automobiles in various ways, such as by moving production to countries not subject to the tariffs, by exporting parts and assembling them in the United States, or by lobbying the government for exemptions or tariff reductions.

6. The methods used by foreign companies to get around tariffs may not be efficient for the economy as a whole because they can lead to higher costs and inefficiencies in the supply chain.

However, they may be necessary for individual companies to remain competitive in the short term.

Ultimately, a more efficient solution would be to address the root causes of the trade imbalances that lead to tariffs in the first place.

7. A tariff can be used as a bargaining chip by threatening to impose tariffs on imports from a country unless they make concessions in trade negotiations.

While this can be an effective strategy in certain situations, it can also lead to a trade war and harm both economies.

In general, tariffs should be used sparingly and as a last resort, and efforts should be made to address underlying trade issues through diplomacy and negotiation.

1.35% is the percentage change in the population of the city that grew from the years 2010 to 2020.

The population of the city = 89,000

Percentage in the growth of people from 2010 to 2015 = 6.8%

Percentage in the decline of people from  2015 to 2020 = 4.9%

The formula to calculate the percentage change is:

percentage change = (new value - old value) / old value x 100%

To calculate the population of the city after the growth of 6.8%

Population in 2015 = 89,000 x (1 + 6.8/100)

Population in 2015 = 95,012

To calculate the population of the city after the decline of 4.9%

Population in 2020 = 95,012 x (1 - 4.9/100)

Population in 2020 = 90,199.88

Population in 2020 = 90,200

The total change in the percentage of growth of population in the city is:

percentage change = (new population - old population) / old value * 100%

percentage change = (90,200 - 89,000) / 89,000 x 100%

percentage change = 1,200 / 89,000 x 100%

y - 2 = 2(x + 3)

The width of the path is 24 meters.

Let's call the width of the path "x".

The dimensions of the inner rectangle (the lawn without the path) are 46m by 34m. The dimensions of the outer rectangle (the lawn with the path) are (46+2x) by (34+2x).

Area of path = Area of outer rectangle - Area of inner rectangle

425m² = (46+2x)(34+2x) - (46)(34)

Simplifying and solving for x:

425m² = (2x+46)(2x+34)

425m² = 4x² + 80x + 1564

4x² + 80x - 1161 = 0

We only want the positive value for x, so:

x = (-80 + 272) / 8

x = 24m
