Living with parents: The Pew Research Center reported that 36% of American Millennials (adults ages 18-31) stll live at home wit
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.

You are 100m from the base of a tall building. If your feet are exactly 180m from the top of the building, how tall is the build
KatRina [158]

Answer:

the building would be 280 feet (judging on how this is worded.)

Step-by-step explanation:

you are already 100 meters from the base ( bottom) of the building so you add 180 as you are 180 ft from the top of the building. 100 + 180 is equal to 280.

What is the equation, in standard form, of a parabola that models the values in the table? x~ -1 0 2
Inessa05 [86]
<h2>Steps</h2>
  • Standard Form Equation: f(x) = ax² + bx + c

So firstly, since (0,5) is one of our values we can plug it into the standard form equation to solve for the c variable (since 0 will cancel out the a and b variable):

5=a*0^2+b*0+c\\5=c

Now we know that the value of c is 5. Next, plug in (-1,12) into the standard form equation and simplify (remember to also plug in 5 for the c variable):

12=a*(-1)^2+b*(-1)+5\\12=a-b+5\\7=a-b

Next, plug (2,15) into the standard form equation and simplify:

15=a*2^2+b*2+5\\15=4a+2b+5\\10=4a+2b\\5=2a+b

Now, with our last two simplified equations we will create a system of equations:

7=a-b\\5=2a+b

Now, I will be using the elimination method with this system. With the system, add up the equations together and you will get:

12=3a

From here, we can solve for the a variable. With it, just divide both sides by 3:

4=a

Now that we know the value of a, plug it into either equation to solve for the b variable:

7=4-b\\3=-b\\-3=b\\\\5=2(4)+b\\5=8+b\\-3=b

<h2>Answer</h2>

Putting all of our obtained values together, your final answer is:

f(x)=4x^2-3x+5
