What are the values displayed on the plinko board for the theoretical mean (µ) and the sample mean (xavg)? What are the values displayed on the plinko board for the theoretical standard deviation (σ) and sample standard deviation

a4 - 3a2 - 1

step-by-step explanation:

step   1   :

equation at the end of step   1   :

  ((a4) -   3a2) -   1

step   2   :

trying to factor by splitting the middle term

2.1     factoring   a4-3a2-1  

the first term is,   a4   its coefficient is   1 .

the middle term is,   -3a2   its coefficient is   -3 .

the last term, "the constant", is   -1  

cosine

step-by-step explanation:

i think the correct option is the second option.

if you need just tell me and i will come to the rescue.
