A trapezoid pyramid has a base area of 128 square centimeters. If it’s volume is 10,240 cubic centimeters, what is the height of

White raven [17]

Answer:

The height of the pyramid is $1.875\ cm$

Step-by-step explanation:

we know that

The volume of the trapezoid pyramid is equal to

$V=Bh$

where

B is the area of the trapezoid base

h is the height of the pyramid

we have

$B=128\ cm^{2}$

$V=240\ cm^{3}$

substitute and solve for h

$240=(128)h$

$h=240/(128)=1.875\ cm$

Answer:

Standard Deviation = 3.22

Variance = 10.36

Step-by-step explanation:

x P(x) x × P(x) x² x² × P(x)

19 0.20 3.8 361 72.2

10 0.20 2 100 20

11 0.30 3.3 121 36.3

12 0.20 2.4 144 28.8

13 0.10 1.3 169 16.9

____________________________________________

12.8 174.2 => Total

<em><u>Mean Formula</u></em>

$\mu_x = \sum(x \times P(x))$ $= 12.8$

$\mu_x^2 = 163.84$

<em><u>Variance Formula</u></em>

$\sigma _x^2 = \sum[x^2 \times P(x)] - \mu_x^2$

$= 174.2- 163.84\\\\=10.36$

<em><u>Standard Deviation Formula</u></em>

$Standard\ deviation, \ \sigma_x = \sqrt{Variance}$

$=\sqrt{10.36}\\\\=3.218$
