Answer:
The approximate solution of the system of equations is the point (-2.7,2.1)
Step-by-step explanation:
we have
-----> equation A
-----> equation B
Solve the system by graphing
Remember that the solution is the intersection point both graphs
using a graphing tool
The solution is the point (-2.714,2.143)
see the attached figure
therefore
The approximate solution of the system of equations is the point (-2.7,2.1)
Answer:
Therefore, equation of the line that passes through (2,2) and is parellel to the line
is 
Step-by-step explanation:
Given:
a line 
To Find:
Equation of line passing through ( 2, 2) and is parellel to the line y=7x
Solution:
...........Given
Comparing with,

Where m =slope
We get

We know that parallel lines have Equal slopes.
Therefore the slope of the required line passing through (2 , 2) will also have the slope = m = 7.
Now the equation of line in slope point form given by

Substituting the points and so we will get the required equation of the line,

Therefore, equation of the line that passes through (2,2) and is parellel to the line
is 
Answer:
its 0.5
Step-by-step explanation:
247 divided by 10^2 is 2.47 and 247 times 10^2 is 24,700
Answer:
(a)
-- Population Mean
(b)
--- Population standard deviation
(c) See Explanation
Step-by-step explanation:
Given:
Cigarette tax for 20 regions
Solving (a): The population mean
This is calculated as:




So, we have:


Solving (b): The population standard deviation
This is calculated as:



So:



Solving (c):
Population mean tells the average amount while the standard deviation represents the spread from the calculated mean
Option (4) is correct
