The side length of the base of a square pyramid is 30 centimeters. The height of the pyramid is 45 centimeters.

puteri [66]

Answer:

volume = 13500 $cm^{3}$

Step-by-step explanation:

For a given pyramid, its volume can be determined by:

volume of pyramid = $\frac{lwh}{3}$

Where: l is the base length, w is the base width and h id the height of the pyramid.

For the given question, l 30 cm, w = 30 cm and h = 45 cm.

So that,

volume = $\frac{30*30*45}{3}$

= $\frac{40500}{3}$

= 13500

volume = 13500 $cm^{3}$

The volume of the pyramid is 13500 $cm^{3}$ .

Answer:

The right answer is " $0.2$ ".

Step-by-step explanation:

The given values are:

$\bar{x_0} = 3.7$

$s_o=4.95$

$t_{\frac{0.05}{2} }=2.2621$

As we know,

95% confidence for $\mu_0$ will be:

= $\bar{x_0} \pm t_{\frac{0.05}{2} },n-1\times \frac{s_o}{\sqrt{n} }$

The lower bound will be:

= $3.7-2.2621\times \frac{4.95}{\sqrt{10} }$

= $0.16\simeq 0.2$

The upper bound will be:

= $3.7+2.2621\times \frac{4.95}{\sqrt{10} }$

= $7.23\simeq7.2$

Thus the right answer is " $0.2$ "
