S’(12,-20) T’(0,-8) U’(-12,-20)
Answer:
B and E
Step-by-step explanation:
Why not look up "standard deviation" yourself, to be sure? But yes, the std. dev. is the sqrt of the variance.
So for example we have
1/2 divided by 1/6
What we will do it’s
Leave the first one As it is
Turn the second fraction (the one you want to divide by) upside down
The change the divide to multiply
Multiply the first fraction by that reciprocal
Simplify the fraction (if needed)
So it’s will be like this
1/2 x 6/1 = 6/2
Simplify it
6/2 =3
I hope it’s will help u ✨
