Answer: True
Explanation:
The definition of minimum spanning tree(MST) says that the graph must be connected and undirected to be considered for MST. It has (V-1) edges where V is the number of vertices. The minimum spanning tree is implemented using Kruskal's algorithm whereby it starts by considering the minimum weighted edge and covers all the edges upto (V-1) edges. So for MST it has to be connected
Answer: B. PDF
Explanation:
Portable Document Format (PDF) is such an important document that it is considered the international standard for information and document exchange. It is used for letters, resumes and even electronic contracts.
PDF was developed by Adobe to make it independent of the device or application it is being viewed on and combines layers of information into one layer thereby making it a flat document.
The answer is 4 because all computers use variables to process something
Answer:
accounting system
Explanation:
The most common response variable modeled for cropping systems is yield, whether of grain, tuber, or forage biomass yield. This yield is harvested at a single point in time for determinate annual crops, while indeterminate crops and grasslands may be harvested multiple times. Although statistical models may be useful for predicting these biological yields in response to some combination of weather conditions, nutrient levels, irrigation amounts, etc. (e.g., Schlenker and Lobell, 2010, Lobell et al., 2011), they do not predict responses to nonlinearities and threshold effects outside the range of conditions in data used to develop them.
In contrast, dynamic cropping and grassland system models may simulate these biological yields and other responses important to analysts, such as crop water use, nitrogen uptake, nitrate leaching, soil erosion, soil carbon, greenhouse gas emissions, and residual soil nutrients. Dynamic models can also be used to estimate responses in places and for time periods and conditions for which there are no prior experiments. They can be used to simulate experiments and estimate responses that allow users to evaluate economic and environmental tradeoffs among alternative systems. Simulation experiments can predict responses to various climate and soil conditions, genetics, and management factors that are represented in the model. “Hybrid” agricultural system models that combine dynamic crop simulations with appropriate economic models can simulate policy-relevant “treatment effects” in an experimental design of climate impact and adaptation (Antle and Stockle, 2015).
