You put the x=6
6³-4(6)²-12(6)+15=15
Answer:
Mean = 35
Variance = 291.7
Step-by-step explanation:
Data provided in the question:
X : 1, 2, 3, 4, 5, 6
All the data are independent
Thus,
The mean for this case will be given as:
Mean, E[X] = 
or
E[X] = 
or
E[X] = 3.5
For 10 days, Mean = 3.5 × 10 = 35
And,
variance = E[X²] - ( E[X] )²
Now, for this case of independent value,
E[X²] = 
or
E[X²] = 
or
E[X²] = 
or
E[X²] = 15.167
Therefore,
variance = E[X²] - ( E[X] )²
or
variance = 15.167 - 3.5²
or
Variance = 2.917
For 10 days = Variance × Days²
= 2.917 × 10²
= 291.7
Answer:- A line is the undefined geometric term can be described as a one-dimensional set of points that has no beginning or end.
Explanation :-
In geometry, there are three undefined terms : 1) point 2) line 3) plane
- A point has zero dimensions . It has two dimensions in plane and three dimensions in space.
- A line is said to be a one dimensional set of points that has no beginning or end.It has only length.
- A plane has two dimensions.
- Distance is not a geometic term.
<span>Parallel lines are two lines that are always the same distance apart and never touch. In order for two lines to be parallel, they must be drawn in the same plane, a perfectly flat surface like a wall or sheet of paper. Any line that has the same slope as the original will never intersect with it.
