The correct answer is option 4. The segment of the supply curve that is supplied least elastic is ab.

The supply curve is the graph of the relationship between the price of a good and the quantity supplied. The degree of elasticity of supply is determined by how much the quantity supplied changes in response to a change in price. If the supply curve is more elastic, it means that the quantity supplied changes more in response to a change in price, while if it is less elastic, it means that the quantity supplied changes less in response to a change in price.

The segment along which the supply is least elastic is indicated by the flatter portion of the curve, where a change in price results in a smaller change in quantity supplied. In this case, segment ab has the least elastic supply.

When constructing a confidence interval for a population proportion, it is important to consider the sample size in relation to the population size. This is because the accuracy of the estimate depends on the sample size.

The rule of thumb is that the sample size should be large enough so that the sample proportion is at least 10% and the sample size is not greater than 10% of the population size. .

For example, if the population size is 100,000, then the sample size should be at least 100 (10% of 100,000) and not greater than 10,000 (10% of 100,000). This is because a sample proportion of 10% provides enough information to make a reasonable estimate of the population proportion, and a sample size of 10,000 ensures that the sample is not so large that it becomes representative of the population.

If the sample size is too small, the confidence interval will be wider and less accurate, and if the sample size is too large, it becomes more difficult to make inferences about the population from the sample. Therefore, it is important to strike a balance between sample size and accuracy.

The value of the secθ for the unit circle in the first quadrant is 21/8.

The terminal sides coincide at the same angle whether the angles are rotated clockwise or anticlockwise. A ray's rotation around its starting point is quantified by an angle. The starting side of that angle refers to the original beam, and the terminal side denotes the ray's final position following its rotation.

Given The terminal side of the angle, θ intersects the unit circle in the first quadrant at x=8/21

which means cosθ  = 8/21

and we know secθ is the inverse of cosθ

so secθ  = 1/cosθ

1. The price elasticity of demand for pen is 0.5

2. The cross price elasticity of demand for the commodity is 0.667

3. The cross price elasticity of demand is 0.8

The degree to which demand reacts to a change in an economic component is known as elasticity of demand. The most prevalent economic component considered when calculating elasticity is price. Income level and the accessibility of substitutes are further considerations. Elasticity gauges how demand changes in response to shifting economic conditions.

Given:

1. The demand for pen decreased from 100 to 70.

So, the percentage change in quantity

= (100 -70) / 100 = 0.3 = 30%

percentage change in the price

= (5 - 2) / 5

= 3/5

= 60 %

So, Cross price elasticity = 30% / 60% = 0.5

2. The quantity demanded of a commodity decreased from 50kg to 30kg.

So, the percentage change in quantity

= (50- 30)/50

= 40%

and, percentage change in price

= (8- 5)/5

= 60%

Then, cross price elasticity

= 40% / 60%

= 0.6667

Now, If the price of the commodity rather decreased from Gh¢5.00 to Gh¢2.50

So, the percentage change in price

= (5 - 2.5)/5

= 50%

Then, cross price elasticity

= 40% / 50%

d = 2d/3 = 4d/3, which implies that the distance between obstacle three and obstacle four is the same as the distance between obstacle seven and obstacle nine.

In mathematics, distance refers to a metric of the separation between two points or objects. It is often thought of as a measure of the length of the shortest path between two points. Distance can be represented in various forms such as Euclidean distance, Manhattan distance, and others. In Euclidean distance, the distance between two points is calculated using the Pythagorean theorem, while Manhattan distance is calculated as the sum of the absolute differences of their coordinates. Distance is widely used in various fields such as physics, geography, computer science, and engineering.

Let's call the distance between obstacle three and obstacle four as "d". Similarly, we can call the distance between obstacle seven and obstacle nine as "d".

The distance between obstacle three and obstacle seven is also "d".

So, the total distance between obstacle three and obstacle nine is 2d + d = 3d.

And the total distance between obstacle four and obstacle seven is d + d = 2d.

Since the distance between obstacle three and obstacle seven is the same as the distance between obstacle four and obstacle nine, we have 3d = 2d.

Therefore, d = 2d/3.

Dividing both sides of the equation by d, we get 3 = 2(2/3) = 4/3.

So, d = 2d/3 = 4d/3, which implies that the distance between obstacle three and obstacle four is the same as the distance between obstacle seven and obstacle nine.

The marginal cost of producing x units is equal to 300 multiplied by the sum of 6 and 4x dollars per unit.

The marginal cost for producing x units is calculated by taking the derivative of the cost equation with respect to x. The cost equation is C = 300(6 + 4x). Differentiating with respect to x, the marginal cost is found to be the derivative of the cost equation, which is equal to 300 multiplied by the derivative of the equation, 6 + 4x. The derivative of 6 + 4x is 4, so the marginal cost is 300 multiplied by 4, or 1200 dollars per unit. Therefore, the marginal cost for producing x units is 1200 dollars per unit.
