I might be wrong but I solved it on paper and I got
B=82
H=40
It should be 69.08 that’s what I got
A<span> system of linear equations</span><span> means two or more linear equations.
</span>A system of two linear equations has an infinite number of solutions is the rarest case and it only happens when both the lines are same.
For example,
y = 3x+1 and 4y = 12x +8
These lines will have infinite number of solutions.
Hence,
The best answer is :
<span>B) The two equations are the same line.</span>
Answer:
1. $29.4 million
2. 145.24
3. 145.24
4. 12.05
5. D. No, because the sample is not representative of the whole population.
Step-by-step explanation:
1. The computation of range of the sample data is shown below:-
Range of the sample data = Maximum value - Minimum value
= 42 - 12.6
= $29.4 million
2. For the computation of variance of the sample data first, we need to find out the mean which is shown below:-
Mean = 
= 24.83
The Variance of the sample data
= 
= 
= 145.24
3. The computation of the standard deviation of the sample data is shown below:-
The Standard deviation of the sample
= 
= $12.05155592
or
$12.05
4. No, as the sample does not represent the whole population.
Area : height x width
perimeter : 2(length + width)
