6 0

Answer: (4,-4)

y=-4, x=4

Step-by-step explanation:

-4x=4y

4x-8y=12

-8y=-4x+12  Now I can substitute -4x for 4y

-8y=4y+12

-2y=y+12

-3y=12

y=-4

-4x=4y

-4x=4(-4)

x=4

Lera25 [3.4K]

Answer:

A.

\mathbf{The \  sample \  comes  \ from \  a \  population \ of \ Millennial \ students } \mathbf{at \  their \ campus\ where \ 3 6\%\ still\ live\ at\ home\ with\ their \  parents}

Step-by-step explanation:

From the given information.

The proportion of American Millennials still with their parents = 0.36

The sample size  = 300

Sample proportion = 0.43

Level of significance = 0.006

P-value = 0.006

Null hypothesis:

\mathbf{H_o: Of  \ Millennial \ students  \ at \ their \ campus, \ 36\% \  }\mathbf{ live \ at \  some  \ with  \ their \  parents . }

\mathbf{H_a: More \ than \ 36\%  \ of  \ Millennial \ students  \ at \ their \ campus \ live \ at \ home }\mathbf{ \ with \ their \ parents}

The required task is to determine the assumption about the sample that underlies the hypothesis test from the given options.

A.

\mathbf{The \  sample \  comes  \ from \  a \  population \ of \ Millennial \ students } \mathbf{at \  their \ campus\ where \ 3 6\%\ still\ live\ at\ home\ with\ their \  parents}

This is because the student wants to check if the null hypothesis ( which states that of Millennial students at their campus, 36% live at home with their parents) is correct or not.
