Answer:
the average probability of all possible outcomes of a future event occurring, weighted by each possible outcome individually
Step-by-step explanation:
An experiment can be defined as an investigation which typically involves the process of manipulating an independent variable (the cause) in order to be able to determine or measure the dependent variable (the effect).
This ultimately implies that, an experiment can be used by scientists to show or demonstrate how a condition causes or gives rise to another i.e cause and effect, influence, behavior, etc in a sample.
In Statistics, an expected value can be defined as the average probability of all possible outcomes of a future event occurring in an experiment, weighted by each possible outcome individually. Thus, an expected value in theory refers to the outcome an individual expect to obtain from an experiment in the long-run.
Mathematically, an expected value can be calculated by summing the products of each distinct outcome and their probability respectively.
Answer:
400
Step-by-step explanation:
Because 365 is closer to 400 than it is to 300, 365 rounded to the nearest hundred is 400.
C , the little 5 at the top represents how many times 7 is multiplied.
Answer:
6k-5
Step-by-step explanation:
8k-(5+2k) write the equation out
8k-5-2k distribute the (-) to everything inside the parenthesis
6k-5 combine like terms
