Answer: The answer is NO.
Step-by-step explanation: The given statement is -
If the graph of two equations are coincident lines, then that system of equations will have no solution.
We are to check whether the above statement is correct or not.
Any two equations having graphs as coincident lines are of the form -
If we take d = 1, then both the equations will be same.
Now, subtracting the second equation from first, we have
Again, we will get the first equation, which is linear in two unknown variables. So, the system will have infinite number of solutions, which consists of the points lying on the line.
For example, see the attached figure, the graphs of following two equations is drawn and they are coincident. Also, the result is again the same straight line which has infinite number of points on it. These points makes the solution for the following system.
Thus, the given statement is not correct.
Answer:
n has to be at least 16577.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of 
, and a confidence level of 
, we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of 
.
The margin of error is:
Out of n randomly selected students she finds that that exactly half attend their home basketball games.
This means that 
99% confidence level
So 
, z is the value of Z that has a pvalue of 
, so 
.
About how large would n have to be to get a margin of error less than 0.01 for p
We have to find n for which M = 0.01. So
Rounding up
n has to be at least 16577.
Answer:
Andrew: 6.25 days
Bailey: 25 days
Step-by-step explanation:
Pretty sure Desmos will help you with this more than anything else, but here goes:
The maximum height reached is 66.016. The ball will hit the ground in 4 seconds. The best domain is -0.063≤x≤4. I'm not too sure about -0.063, it's either -0.063 or -1.
Hope this helps!
