If 11∘11=4,22∘22=16,33∘33=36,and 44∘44=6411∘11=4,22∘22=16,33∠˜33=36,and 44∘44=64 then what is the value of 55∘5555∘55 ?

answer: .64

step-by-step explanation

set up the formula for standard deviation for this set of numbers, then simplify

dont't really have enough info here but its likely

sss for the three sides being congruent ( its stands for side side side)

or

sas   for side angle side.   so a side is congruent and and angle and a side

we need to divide the number of toy dinosaurs, 156, by the number of brothers, 4:

in order to estimate, we can use compatible numbers:

156 ÷ 4

  ↓

160   ÷ 4 = 40        

the correct answer is a).

the anwers is yes.
