Long-distance calling plan A offers flat-rate service at 10 cents per minute. Calling plan B charges 99 cents for every call under 20 minutes; for calls over 20 minutes, the charge is 99 cents for the first 20 minutes plus 10 cents for every additional minute. (Note that these plans measure your call duration exactly, without rounding to the next minute or even second. ) If your long-distance calls have exponential distribution with expected value 15 minutes, which plan offers a lower expected cost per call

Answers

Answer 1

Comparing the expected costs, we find that plan A offers a lower expected cost per call at $1.50, while plan B (for calls under 20 minutes) is $0.99.

To determine which plan offers a lower expected cost per call, we need to calculate the expected cost for each plan based on the given information.

Let's start with plan A, which offers a flat rate of 10 cents per minute. Since the expected call duration is 15 minutes, the expected cost per call under plan A would be:

Expected Cost Plan A = (Expected Call Duration) * (Cost per minute) = 15 minutes * $0.10 = $1.50.

Now let's move on to plan B, which has a different pricing structure. For calls under 20 minutes, the charge is a flat rate of 99 cents. Since the expected call duration is 15 minutes, the expected cost per call for calls under 20 minutes under plan B would be:

Expected Cost Plan B (calls under 20 minutes) = $0.99.

For calls over 20 minutes, the charge is 99 cents for the first 20 minutes plus 10 cents for every additional minute. The expected cost per call for calls over 20 minutes under plan B would be:

Expected Cost Plan B (calls over 20 minutes) = $0.99 + [(Expected Call Duration - 20) * $0.10].

Since the expected call duration is 15 minutes and falls under the 20-minute threshold, the expected cost per call for calls over 20 minutes is not applicable.

In conclusion, based on the given expected call duration and the cost structure of the two plans, plan A offers a lower expected cost per call.

A room with columns. Every pair of columns extends up to create an arch in the ceiling. What type of construction is this an example of? Why might this type of construction be chosen?.

Answers

This is an example of the architectural construction known as "arcuated" or "arched" construction.

The construction described, with pairs of columns extending up to create arches in the ceiling, is known as arcuated or arched construction.

This type of construction relies on the use of arches and vaults to distribute the weight and support the structure.

Arcuated construction offers several advantages. Firstly, arches are known for their strength and ability to bear heavy loads. The curved shape of the arches helps distribute the weight more evenly, allowing for greater stability and durability of the structure. This construction technique also allows for larger open spaces and higher ceilings, as the arches provide support without the need for additional columns or walls.

Architects and builders may choose this type of construction for its aesthetic appeal. The use of arches and columns can create a sense of grandeur, elegance, and architectural beauty. It has been employed in various architectural styles throughout history, such as Roman, Gothic, and Renaissance, to evoke a sense of awe and create visually stunning spaces.

Furthermore, arched construction allows for the creation of unique interior designs and decorative elements. The arches can be embellished with intricate carvings, ornamental details, or stained glass, enhancing the overall aesthetic value of the space.

Overall, arcuated construction offers both structural benefits and aesthetic appeal. It provides strength, stability, and the ability to create visually striking spaces, making it a popular choice in architectural design.
