The total surface area of this cuboid is 112cm squared find the value of x

soldier1979 [14.2K]

Answer:

$x=2\sqrt{\frac{14}{3}}\ units$ or $x=\frac{2}{3}\sqrt{42}\ units$

Step-by-step explanation:

we know that

The surface area of a cube is equal to

$SA=6x^{2}$

where

x is the length side of a cube

In this problem we have

$SA=112\ cm^{2}$

substitute in the formula and solve for x

$112=6x^{2}$

$x^{2}=112/6$

square root both sides

$x=\sqrt{\frac{112}{6}}\ units=2\sqrt{\frac{14}{3}}\ units=\frac{2}{3}\sqrt{42}\ units$

H is the correct choice.

The diagram means that parallelograms come in two kinds: rectangles and rhombuses.

So,
.. all rhombuses are parallelograms
.. all rectangles are parallelograms
.. no rectangles are rhombuses
This diagram only recognizes parallelograms that are rectangles and rhombuses. There are also other kinds of parallelograms, but those are not shown here.

A study of women’s weights found that a randomly selected sample of 234 women had a mean weight of 157.3 lb. Assuming that the p

Scilla [17]

Answer:

$157.3-1.96\frac{15.6}{\sqrt{234}}=155.301$

$157.3+1.96\frac{15.6}{\sqrt{234}}=159.299$

So on this case the 95% confidence interval would be given by (155.301;159.299)

And the best option would be:

B. (155.3, 159,3)

Step-by-step explanation:

Information given

$\bar X=157.3$ represent the sample mean

$\mu$ population mean (variable of interest)

$\sigma =15.6$ represent the population standard deviation

n=234 represent the sample size

Confidence interval

The confidence interval for the mean is given by the following formula:

$\bar X \pm z_{\alpha/2}\frac{\sigma}{\sqrt{n}}$ (1)

The Confidence level is is 0.95 or 95%, the significance is $\alpha=0.05$ and $\alpha/2 =0.025$ , the critical value for this case would be $z_{\alpha/2}=1.96$

And replacing we got:

$157.3-1.96\frac{15.6}{\sqrt{234}}=155.301$

$157.3+1.96\frac{15.6}{\sqrt{234}}=159.299$

So on this case the 95% confidence interval would be given by (155.301;159.299)

And the best option would be:

B. (155.3, 159,3)
