What is the standard deviation of the random variable X, "the number that
comes up on the die"?
A. 3.5
B. 1.708
C. 3.745
D. 14.028
E. 2.291

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2

the answers might not be correct use at own risk

believe it or not anna is correct good job anna give me a fist bump there u go gal

40 i don’t know lololol
