Answer:

running. Running is the activity of moving fast on foot, especially as a sport. The running of something such as a business is the managing or organizing of it. ... For example, if something has happened every day for three days, you can say that it has happened for the third day running or for three days running.

A principal of a large high school wants to estimate the true proportion of high school students who use the community's public

denis-greek [22]

Considering the margin of error of a confidence interval, it is found that the correct option is:

It would be half as wide.

<h3>What is the margin of error of a confidence interval?</h3>

It is modeled by:

$M = z\frac{s}{\sqrt{n}}$

In which:

z is the critical value.

s is the standard deviation.

n is the sample size.

From this, we get that the margin of error is inversely proportional to the square root of the sample size. Then, multiplying the sample size by 4, when it changes from 50 to 200, cuts the margin of error in half, making the interval half as wide.

suppose you have 76 feet of fencing to enclose a rectangular dog pen. The function A=38x-x^2, where x= width, gives you the area

yan [13]

If A=38x-x^2 then

dA/dx=38-2x

d2A/dx2=-2

Since the acceleration, d2A/dx2 is a constant negative, when velocity, dA/dx=0, it will be an absolute maximum for A(x)

dA/dx=0 only when 38=2x, x=19

A(19)=38(19)-19^2

A(19)=722-361

A(19)=361 ft^2

So the maximum possible area is 361 ft^2

(This will always be true as the maximum possible area enclosed by a given amount of material will always be a perfect square...)
