A Gallup survey of 2322 adults (at least 18 years old) in the U.S. found that 408 of them have donated blood in the past two yea

Flura [38]

Answer: $(0.163,\ 0.189)$

Step-by-step explanation:

The confidence interval for population proportion(p) is given by :-

$\hat{p}\pm z^*\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}$

, where $\hat{p}$ = Sample proportion.

n= Sample size.

z* = Critical value.

Let p = Proportion of adults in the U.S. who have donated blood in the past two years.

As per given , we have

n= 2322

Sample proportion of adults in the U.S. who have donated blood in the past two years. : $\hat{p}=\dfrac{408}{2322}\approx0.1757$

By z-table , the critical value for 90% confidence : z*= 1.645

Then, the 90% confidence interval for the population proportion of adults in the U.S. who have donated blood in the past two years will be

$0.1757\pm ( 1.645)\sqrt{\dfrac{0.1757(1-0.1757)}{2322}}$

$0.1757\pm ( 1.645)\sqrt{0.0000623727433247}$

$0.1757\pm ( 1.645)(0.00789764163056)$

$0.1757\pm 0.013$

$=(0.1757- 0.013,\ 0.1757+ 0.013)$

$=(0.1627,\ 0.1887)\approx(0.163,\ 0.189)$

Hence, the 90% confidence interval for the population proportion of adults in the U.S. who have donated blood in the past two years. = $(0.163,\ 0.189)$

a method for finding the maximum or minimum value of a quantity that is subject to various limitations is called

Sveta_85 [38]

The minimum or maximum value of a quantity are what are used to maximize or minimize a function.

<em>The method for finding these minimum or maximum value is linear programming.</em>

<em />

Take for instance, the following parameters:

$\mathbf{Maximize\ z = 2x + 3y}$

Subject to:

$\mathbf{2x + y \ge 10}$

$\mathbf{x - y < 2}$

$\mathbf{x ,y >0}$

The above is an illustration of a linear programming.

It is useful in the following areas:

To formulate real life problems
To get an optimal solution
To maximize profit and minimize cost
Etc

Find the limit, if it exists (picture below)

valentinak56 [21]

Answer:

c. $\frac{1}{2 \sqrt{7} }$

Step-by-step explanation:

When plugging in zero into the given equation:

$\lim_{x \rightarrow 0} \frac{\sqrt{x + 7} - \sqrt{7} }{x} = \frac{0}{0}$

Answer is in indeterminate form = use L'Hospital's Rule:

(Derivative of the top / Derivative of the bottom)

$\lim_{x \rightarrow 0} \frac{ \frac{1}{2} (x + 7)^{ \frac{-1}{2}} - 0 }{1}$

Rearranged equation:

$\lim_{x \rightarrow 0} \frac{1}{2 \sqrt{x + 7} }$

Plug zero back into equation:

$\lim_{x \rightarrow 0} \frac{1}{2 \sqrt{x + 7} } = \frac{1}{2 \sqrt{0 + 7} } = \frac{1}{2 \sqrt{7} }$

Answer:

$\lim_{x \rightarrow 0} \frac{\sqrt{x + 7} - \sqrt{7} }{x} = \frac{1}{2 \sqrt{7} }$
