Describe the location of the point having the following coordinates.
2 answers:
Answer: The point will be located on the negative Y-axis.
Step-by-step explanation: We are given to describe the location of the point with zero abscissa, negative ordinate.
ABSCISSA : It is the x-coordinate of a point.
ORDINATE : It is the y-coordinate of a point.
Since the given point has zero abscissa, so its x-coordinate is 0.
That means, the point lies on the Y-axis.
Also, since the point has negative ordinate, so its y-coordinate is negative.
That is, the point lies on the negative Y-axis.
The point is of the form (0, y) = (0, -b), where b > 0.
Thus, the point lies on the negative Y-axis.
Let, b = 3, then the point is (0, y) = (0, -3).
The location of the point is shown in the attached figure. It lies on the negative Y-axis at a distance of 3 units from the origin.

Answer:
The error is at step (3) .
The correct step (3) will be,
= [by using the laws of indices]
All other steps are correct.
Step-by-step explanation:
The error is at the step (3) , because the student has tried to prove the quotient rule of logarithms by using the property i.e., 'The quotient rule of logarithm' itself , i.e. ,by assuming the property does hold before proving it. So, the proof is fallacious.
The correct step (3) will be,
= [by using the laws of indices]
All other steps are correct.
Answer:
lower 95% Cl is 0.292
Step-by-step explanation:
p^ = 0.4783
n = 23
for 95% Cl,
z = 1.9600
Inputting all the available data into P as attached below
LCL = 0.292
UCL = 0.670
therefore, lower 95% Cl = 0.292
