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:
m = 68 - c
Step-by-step explanation:
It is given that Tegan needs to make 68 more snow blocks to finish building an igloo.
Let m be the number of blocks Tegan still needs to make and c be the number of completed blocks.
If total number of required block is 68 and c blocks are completed then the remaining blocks is the difference between 68 and c.
Number of blocks Tegan still needs to make = 68 - c
We know that c represent the number of blocks Tegan still needs to make.
m = 68 - c
Therefore, the required equation is m = 68 - c.
Answer:
It's (7x+2)(3x−2)
Step-by-step explanation:
Answer:
$801
Step-by-step explanation:
The cost is computed as ...
total cost = yearly fee + time-based charge
= $129 + ($16/h)·(42 h)
= $129 + 672
total cost = $801
