Step-by-step explanation:

Variance can be said to be a measure of dispersion for a random sample.

Variance = pq/n

When given the variance, we can find the standard deviation.

Standard deviation = √variance

= √pq/n

ABCD Is a rhombus .AC=8cm and BD=3.5 cm .what is the aera of the rhombus

Triss [41]

$d_1;\ d_2-the\ diagonals\ of\ the\ rhombus\\\\The\ area\ of\ the\ rhombus:A=\dfrac{d_1\cdot d_2}{2}.\\\\d_1=|AC|=8\ cm;\ d_2=|BD|=3.2\ cm\\\\A=\dfrac{8\cdot3.5}{2}=4\cdot3.5=\boxed{14\ (cm^2)}$

If tan fº = 2/1 and the measure of yw is 8 units, what is the measure of xw?

erma4kov [3.2K]

*see attachment for the figure referred to

Answer:

4 units

Step-by-step explanation:

Given that $tan(f) = \frac{2}{1}$ , therefore, it follows that:

$tan(f) = \frac{opp}{adjacent} = \frac{YW}{XW} = \frac{8}{XW}$ ,

If the ratio of YW to XW = 2:1, therefore, $\frac{2}{1} = \frac{8}{XW}$

Cross multiply to find XW

$XW*2 = 8*1$

$XW = \frac{8}{2} = 4 units$
