Answer:

Proportion = 0.6 or 60 %

Step-by-step explanation:

Given:

- The obtained 95% confidence interval of a sample of adults rooting for North High:

                                         (0.52 , 0.68)

- Sample size n = 150

Find:

What proportion of the 150 adults in the survey said they were rooting for North High​ School?

Solution:

The proportion of adults rooting for North high corresponds to the mean value of interval, as follows:

                             Proportion = ( 0.52 + 0.68 ) / 2

                            Proportion = 0.6 or 60 %

If you replace the x with 11, the new equation would be 10+5(11)=65. First, multiply 5 and 11, your answer would be 55, then add the ten, you would get 65. Which makes the equation true, because 65=65.
I hope this helps

What is the equation of the line that passes through the point (-6,-6)and has a slope of -\frac{1}{3}− ?
Gnesinka [82]

9514 1404 393

Answer:

  y +6 = (-1/3)(x +6)

Step-by-step explanation:

Given a point and a slope, it is appropriate to use the point-slope form to represent the equation:

  y -k = m(x -h) . . . . . line with slope m through point (h, k)

For your point and slope, the equation is ...

  y -(-6) = -1/3(x -(-6))

  y +6 = -1/3(x +6)

__

Of course, this can be rearranged to whatever form you need.

  y = -1/3x -8 . . . . slope-intercept form

  x +3y = -24 . . . . standard form
