x + y= 9 and x - y= 3
rearrange the second equation:
x - y= 3
x = 3 + y
x -3 = y
substitute y with "x-3" in the first equation and solve
x + y= 9
x + (x-3)= 9
2x -3 = 9
2x = 12
x = 6
you could also start with the first equation and substitute y in the second.
graphically speaking, it's the intersection point of to lines, at least the six-part of the point.
Y + 5 = -2 Mathematical equation that represents this problem.
y = -7 Subtract 5 from each side.
Answer: y = -7
The completion of the tabs are:
- The value of
is the sample proportion. - The value of
is found by evaluating 
- The value of n is the sample size.
- The value of E is the margin of error.
- The value of p is the population proportion.
- α = 0.05.
<h3>What is
the margin of error.?</h3>
You may calculate how many percentage points your findings will deviate from the actual population figure by using something called a margin of error.
In conclusion
- The worth of p^ is the fraction of the sample.
- The worth of p^ is discovered by assessing
- The sample size is given by the number n.
- The margin of error is expressed as E's value.
- The population percentage is represented by the value of p.
In conclusion,
