Lyrx [107]

The area of a parallelogram can be found in the same way as that of a rectangle, so base x height. To find the base we have to do area ÷ height or 18 1/3 ÷ 3 1/3= 5.5 feet

If total liabilities decreased by $60,000 and stockholders' equity increased by $20,000 during a period of time, then total asse

Lena [83]

Answer:

$40,000 decrease

Step-by-step explanation:

Change in total assets = Total Liabilities Decreased- StockHolders' equity increased

Change in total assets = 60000 - 20000

Change in total assets = $40,000 decrease

So, If total liabilities decreased by $60,000 and stockholders' equity increased by $20,000 during a period of time,<u><em>then the change in total assets will consist of a </em></u><u><em>decrease of $40,000 </em></u>

What are the points of inflection of k(x)=sinx-(1/4)sin2x

zalisa [80]

Answer:

Option d is correct.

Step-by-step explanation:

The point of inflection of a function y = f(x) at a pointy c is given by f''(c) = 0.

Now, the given function is

$k(x) = \sin x - \frac{1}{4}\sin 2x$

Differentiating with respect to x on both sides we get,

$k'(x) = \cos x - \frac{1}{2} \cos 2x$

Again, differentiating with respect to x on both sides we get,

$k''(x) = - \sin x + \sin 2x = - \sin x + 2 \sin x \cos x$

So, the condition for point of inflection at point c is

k''(c) = 0 = - sin c + 2 sin c cos c

⇒ sin c(2cos c - 1) = 0

⇒ sin c = 0 or $\cos c = \frac{1}{2}$

⇒ c = 0 or $c = \pm \frac{\pi}{3}$

Therefore, option d is correct. (Answer)

Kay [80]

Answer:

The number of people surveyed was 330.

Step-by-step explanation:

The (1 - <em>α</em>)% confidence interval for the population proportion is:

$CI=\hat p\pm z_{\alpha/2}\cdot \sqrt{\frac{\hat p(1-\hat p)}{n}}$

The margin of error for this interval is:

$MOE= z_{\alpha/2}\cdot \sqrt{\frac{\hat p(1-\hat p)}{n}}$

The information provided is:

$\hat p=0.37\\MOE=0.05\\\text{Confidence level}=0.94\\\Rightarrow \alpha=0.06$

The critical value of <em>z</em> for 94% confidence level is, <em>z</em> = 1.88.

*Use a <em>z</em>-table.

Compute the value of <em>n</em> as follows:

$MOE= z_{\alpha/2}\cdot \sqrt{\frac{\hat p(1-\hat p)}{n}}$

$n=[\frac{z_{\alpha/2}\times \sqrt{\hat p(1-\hat p)}}{MOE}]^{2}$

$=[\frac{1.88\times \sqrt{0.37(1-0.37)}}{0.05}]^{2}\\\\=(18.153442)^{2}\\\\=329.5475\\\\\approx 330$

Thus, the number of people surveyed was 330.
