How many points need to be removed from this graph so
Softa [21]
2 points. You answer this with the vertical line test. There are two pairs of points with the same x-axis, so they make two vertical lines. For it to be a function, it must pass the vertical line test, so no two points have the same x-axis. I hope this helps :)

A consumer group selected 100 different airplanes at random from each of two large airlines. The mean seat width for the 100 air
Novay_Z [31]

Answer:

Decreasing the sample size decreases the width of the confidence interval.

Step-by-step explanation:

-Let s be the sample standard deviation and \bar X be the sample mean.

#We calculate the 95% confidence interval for the sample size 100 as below:

\bar X\pm z_{0.05/2}\frac{s}{\sqrt{n}}\\\\\\=\bar X\pm 1.960\times\frac{s}{\sqrt{50}}\\\\\\=\bar X\pm 0.1960s

#we then calculate the confidence interval of sample size =50 and of similar mean and standard deviation:

\bar X\pm z\frac{s}{\sqrt{n}}\\\\\\=\bar X\pm z_{0.05/2}\times\frac{s}{\sqrt{n}}\\\\\\=\bar X\pm1.960\times \frac{s}{\sqrt{50}}\\\\\\\\=\bar X\pm0.2772s

#Notice that the smaller sample(n=50) has a narrower confidence interval.

Hence, decreasing the sample size decreases the width of the confidence interval.

Solve the system -10=-2y+x 6y=3x+11
belka [17]

Answer: No Solutions exist

Step-by-step explanation:

We have the following system of equations

-10=-2y+x

6y=3x+11

Rewriting the second equation we have:

-11=-6y+3x

Now we multiply the first equation by -3 and add it to the second equation

30=6y-3x

-11=-6y+3x

---------------------------------

19=0

Equality is not satisfied. Then the system has no solution
