A university dean is interested in determining the proportion of students who receive some sort of financial aid. Rather than ex

amine the records for all students, the dean randomly selects 200 students and finds that 118 of them are receiving financial aid. If the dean wanted to estimate the proportion of all students receiving financial aid to within 3% with 99% reliability, how many students would need to be sampled?

Answer:1866

Step-by-step explanation:

Given

n=200

x=118

Population proportion P=\frac{118}{200}=0.59

\alpha=0.005

Realiability =99%

Z_{\frac{\alpha }{2}}=2.576

Margin of erroe is given by \sqrt{\frac{p\left ( 1-p \right )}{N}}

0.03= \sqrt{\frac{0.59\left ( 1-0.59 \right )}{N}}

85.667=\sqrt{\frac{N}{0.6519}}[tex]N=1865.88[tex]\approx 1866 Students

For what value of x is the function g(x)=x/1-x NOT defined?
VMariaS [17]

The function is definately defined at x=0 but not x=1.

But its just one part of the coordinate (x,y).

If the value of y or f(x) is considered, you'll see that it is never possible to attain f(x)=0. In other terms (x,y)= (0,0) is not a defined point in the graph of the function because the graph doesnt pass through that point.

Now I hope you understood what I meant!

Conclusion- The above function is not defined at all points in the space having the abscissa or x=1 in the coordinate and also at ordinate or y=0 in the coordinate.nation:

PLEASE HELP!! Identify the minium value of the function
timama [110]
Because this is a positive parabola, it opens upwards, like a cup, and the vertex dictates what the minimum value of the function is.  In order to determine the vertex, I recommend completing the square.  Do that by first setting the function equal to 0 and then moving the 9 to the other side by subtraction.  So far: x^2+6x=-9.  Now, to complete the square, take half the linear term, square it, and add that number to both sides.  Our linear term is 6.  Half of 6 is 3 and 3 squared is 9.  So add 9 to both sides. x^2+6x+9=-9+9.  The right side reduces to 0, and the left side simplifies to the perfect square binomial we created while completing this process.  (x+3)^2=0.  Move the 0 back over and the vertex is clear now.  It is (-3, 0).  Therefore, 0 is the minimum point on your graph.  The first choice above is the one you want.

5h+4+52+64=180 what does that equal to
Softa [21]

Answer:

x=12

Step-by-step explanation:

5x+4+64+52=180

We move all terms to the left:

5x+4+64+52-(180)=0

We add all the numbers together, and all the variables

5x-60=0

We move all terms containing x to the left, all other terms to the right

5x=60

x=60/5

x=12

WILL BE MARKED AS BRAINLIEST !!! <br> Solve<br> (−22 −4 + 8)+ (52 + 2 − 25)
anygoal [31]

Answer:

11

Step-by-step explanation:

1) lets get rid of the parentheses, we dont really need them:

−22 −4 + 8+ 52 + 2 − 25

Following order of operations we need to work from left to right

so

-22-4=-26

-26+8=-18

-18+52=34

34+2=36

36-25=11

the answer is 11

hope this helps
