19: He multiplied instead of dividing which will make a totally incorrect answer
Answer:
12 total possible outcomes
Step-by-step explanation:
Because these are independent events, or events that don't rely on each other, the key is to find the possibilites then multiply them all. There are four equal size sections, and three other equal sized sections, so we do 3 * 4 = 12.
Answer:
100
Step-by-step explanation:
discriminant = b^2 - 4ac
here
b = 6, a= 4, c = -4
6^2 -4 •4•-4 = 36 +64 = 100
The two requirements for a proportional relationship are: The ratio of the two variables maintain the same ratio.
Modelling can be done by Graph Data Modelling
Step-by-step explanation:
1.Graph data modeling is the process in which a user describes an arbitrary domain as a connected graph of nodes and relationships with properties and labels.
2.The following tasks are performed in an iterative manner:
Identify entity types.
Identify attributes.
Apply naming conventions.
Identify relationships.
Apply data model patterns.
Assign keys.
Normalize to reduce data redundancy.
Denormalize to improve performance.
3.One such approach is the property graph model, where data is organized as nodes, relationships, and properties (data stored on the nodes or relationships). ... Nodes are the entities in the graph. They can hold any number of attributes (key-value pairs) called properties
