Answer:

The answer is "0.1040"

Step-by-step explanation:

Margin of error=Z_{\frac{\alpha}{2}} \sqrt{\frac{\hat{p}(1-\hat{p})}{n}}\\\\

                          =Z_{\frac{0.10}{2}} \sqrt{\frac{\frac{36}{60}(1-\frac{36}{60})}{60}}\\\\=1.645 \times 0.0632\\\\=0.1040\\\\

The midpoint of the line segment from upper p 1p1 to upper p 2p2 is left parenthesis negative 1 comma 5 right parenthesis(−1,5).
aliya0001 [1]
The coordinates of the second point are (2, 4).

The midpoint formula is:
m=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})

Substituting our information, we have:

(-1, 5)=(\frac{-4+x_2}{2},\frac{6+y_2}{2})

This means that
-1=\frac{-4+x_2}{2} \text{ and } 5=\frac{6+y_2}{2}

Multiply both sides of both equations by 2 to cancel it:
-1\times2=(\frac{-4+x_2}{2})\times2 \text { and } 5\times2=(\frac{6+y_2}{2})\times2
\\
\\-2=-4+x_2 \text { and } 10=6+y_2
\\-2+4=-4+x_2+4 \text { and } 10-6=6+y_2-6
\\2=x_2 \text{ and } 4=y_2

This gives us our coordinates (2, 4)

Which linear function shows a direct variation?
tankabanditka [31]

Answer:

D. Graph D

Step-by-step explanation:D. Graph D

Step-by-step explanation:

We know that, 'Direct Variation or Directly Proportional' is relationship between two variables where one is a constant multiple of the other.

That is, if one variable changes, the other variable also changes in proportion to the first variable.

The general form of 'Direct Variation' is y = kx, where k is a constant i.e. it does not have a y-intercept.

Now, according to our options, we see that the figures of A,B,C are the graphs of the straight lines given by y =-2x+2 , y=2x+2, y=-2x+2 respectively.

Each of these three equations have y-intercept, therefore cannot be the equations of a direct proportion.

Now, in option D, the figure is the graph of straight line y = -x and has no y-intercept.

Hence, the linear function in Graph D shows a direct proportion.
