The following table shows the probability of rolling the numbers 1 through 7 on a fair 7-sided die.
х 1 2 3 4 5 6 7
P(x)1/7 1/7 1/7 1/7 1/7 1/7 1/7
What is the standard deviation of the random variable x, “the number that comes up on the die"?

hi, i am not sure about this one but i think its d,

hope this !

v = 1/3 a^2h

step-by-step explanation:

if the height is 57.7cm and the height of the slant edge is 18.2cm, then the volume is 1/3 a^2h.

sas (side angle side)

aa (angle angle)

sss(side side side)

sas find two sides with an angle in between

aa is finding two angles and the third will add up to 180

sss find all sides
