Explain how bias in the survey might have affected the results. a survey asks teens, “do you, like most teenagers, dislike listening to boring classical music? ” the results show that teens dislike classical music. a. the survey only included teens and so it is not representative of the entire population. b. the phrasing of the question suggests a bias against classical music. c. the survey may have included only teens who do not like classical music. d. the survey probably did not include teens who play in a youth symphony orchestra.

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  

the transverse axis of a hyperbola is the line that contains the two vertices and the two focuses.

in this example (hyperbola of equation x^2/2 - y^2/4 = 1), the transverse axis is the  x-axis  .
