Which of the following is a Dashboard Scoreboard for alignment of the business where information is constantly flowing through the Tiers so immediate actions can be taken?
Answer:
What is a dashboard?
A dashboard is an information management tool used to track KPIs, metrics, and key data points that are relevant to your business, department, or a specific process. Dashboards aggregate and visualize data from multiple sources, such as databases, locally hosted files, and web services. Dashboards allow you to monitor your business performance by displaying historical trends, actionable data, and real-time information.
Dashboards actually take their name from automobile dashboards and they are used in much the same way. For the sake of an analogy, let’s look at a car. There may be hundreds of processes that impact the performance of your vehicle if you look under the hood. Your car’s dashboard summarizes this using visualizations so you can focus on what matters most: safely driving your vehicle.
For businesses, there are hundreds of processes that impact your performance if you look ‘under the hood’, so to speak. And with a wealth of data made available these days, managing and extracting value from it can be difficult. Simplifying data analysis and distribution through tools like dashboards is a way to help businesses rev their engines and make smarter, better, faster data-driven decisions.
And a well designed dashboard levels up your approach to information management. Everyone in the business, regardless of role, has questions about your company performance, whether it be campaign performance, new wins, or churn rate. Dashboards bring everyone (and your metrics) together in one place to answer these questions.

Assume that you have a wireless application you would like to design,build and sell as a commercial product.You have selected a target frequency in the UHF range.How would you decide what frequency to use and how would you get permission to use it ?
The frequency to use depends on the range and distance of signal transmission. There is government communication agency in charge of issuing license in order to get carrier frequency in which the application can work with.
UHF means Ultra - high frequencies which is mostly used in television broadcasting and mobile phone. Frequency range of the UHF is between 300MHz to 3GHz.
Assuming that you have a wireless application you would like to design, build and sell as a commercial product. And you have selected a target frequency in the UHF range.
Most wireless applications make use of radio wave and microwave depending on the range of distance in which the signal will travel.
The first thing to do is to determine the distance. Whether is short or long distance.Then get a license from the right government communication agency so that a carrier wave frequency will be allocated for you.

A. The EOQ before setup reduction.
B. The EOQ after setup reduction.
C. The total and unit cost before and after setup reduction.
Answer:
B the EOQ after setup reduction.
Through a program of setup reduction, thesetup cost is reduced to $20. Run costs are $2 per unit. CalculateThe EOQ after setup reduction. Hence, option B is correct.
What is meant by EOQ?The amount of an order known as a "economic order quantity" (EOQ) is one that lowers the overall cost of acquiring and maintaining inventories of goods or raw materials.
The supplier should be contacted to ascertain the optimal inventory size in order to lower the company's overall annual inventory cost. Economic order quantity, or EOQ, is the phrase. Supply, logistics, and operations management all use this measurement.
In its most basic form, EOQ is a technique for determining the quantity and frequency of orders required to satisfy a particular level of demand while reducing the cost per order.
Thus, option B is correct.

State Conditions necessary for static equilibrium of a particle of a rigid body
Answer:
Conditions for equilibrium require that the sum of all external forces acting on the body is zero (first condition of equilibrium), and the sum of all external torques from external forces is zero (second condition of equilibrium). These two conditions must be simultaneously satisfied in equilibrium.
Hi there!
For a particle to be in static equilibrium:
[tex]\huge\boxed{\Sigma \tau = 0}}[/tex]
The sum of torques acting on the particle must equal 0 Nm.
[tex]\huge\boxed{\Sigma F = 0}}[/tex]
The sum of forces acting on the particle must equal 0 N.
Both of these conditions MUST be met in order for a particle to be in STATIC equilibrium.

Clear my choice
Answer:
C
Explanation:
As horsepower is the rate at which that force torque is a twisting or turning force, horsepower is produced. Hence option C is correct.
What is horsepower?Horsepower is defined as a unit used to describe the pace at which labor is done or to quantify power, frequently in relation to the output of engines or motors. Standardization and types of horsepower vary widely. A car's engine power is measured in horsepower (hp); the greater the number, the more power is transferred to the wheels and, in theory, the faster it will travel.
To put it simply, horsepower is your overall speed and power, whereas torque allows you to feel the sensation of acceleration when you put your foot down. When you realize that horsepower is derived from torque, this makes sense. Torque is a unit of rotational or twisting force. The power an engine produces is referred to as horsepower.
Thus, as horsepower is the rate at which that force torque is a twisting or turning force, horsepower is produced. Hence option C is correct.
