Answer:

A(6,0)

Step-by-step explanation:

x=y−6 ;y=−3x+6

Step: Solve x=y−6 for x:

x=y−6

Step: Substitute y− 6 for x in y=−3x+6:

y=−3x+6

y=−3(y−6)+6

y=−3y+24(Simplify both sides of the equation)

y+3y=−3y+24+3y(Add 3y to both sides)

4y=24

4y

4

=

24

4

(Divide both sides by 4)

y=6

Step: Substitute 6 for y in x=y−6:

x=y−6

x=6−6

x=0(Simplify both sides of the equation)  

Answer:

x=0

and  

y=6

2/3

Step-by-step explanation:

\frac{3}{4} n =  \frac{1}{2}  \\  \\ multiply \: both \: sides \: by \:  \frac{4}{3}  \\  \\ \frac{ \cancel4}{\cancel3}   \times  \frac{\cancel3}{\cancel4} n = \frac{\cancel4 \:  \:  \red{ \bold2}}{3}   \times  \frac{1}{ \cancel2}  \\  \\n =  \frac{2 \times 1}{3 \times 1}  \\  \\ n =  \frac{2}{3}

A poll conducted in 2013 found that 55% of U.S. adult Twitter users get at least some news on Twitter (Pew, 2013). The standard
alina1380 [7]

Answer:

The 99% confidence interval for the fraction of U.S. adult Twitter users who get some news on Twitter is between 49.34% and 60.66%, which means that we are 99% sure that the true percentage of US adult Twitter users who get some news is in this interval.

Step-by-step explanation:

Confidence interval:

A confidence interval has the following format:

M \pm zs

In which M is the sample mean, z is related to the confidence level and s is the standard error.

55% of U.S. adult Twitter users get at least some news on Twitter (Pew, 2013). The standard error for this estimate was 2.2%.

This means that M = 55, s = 2.2

99% confidence level

So \alpha = 0.01, z is the value of Z that has a pvalue of 1 - \frac{0.01}{2} = 0.995, so Z = 2.575.

Lower bound of the interval:

M - zs = 55 - 2.575*2.2 = 49.34

Upper bound:

M + zs = 55 + 2.575*2.2 = 60.66

The 99% confidence interval for the fraction of U.S. adult Twitter users who get some news on Twitter is between 49.34% and 60.66%, which means that we are 99% sure that the true percentage of US adult Twitter users who get some news is in this interval.
