The relationship between the coefficient of determination and coefficient of correlation is such that: the coefficient of determination is the coefficient of correlation squared

the two are unrelated

both are equal

the coefficient of determination is the square root of the coefficient of correlation

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol

an = 22 + (n-1) *6

110 seats

step-by-step explanation:

an=a1+(n-1)(d)

a1 = 22   this is the first item in the sequence

d =6   this is how the sequence goes up

a)   an = 22 + (n-1) *6

b) a12 = 22 + (12-1) *6

    a12 = 22+11*6

  a12 = 22 +88

  a12 = 110

answer: a parabola

steps:

(x-1)(x+4)   = x(x+4) - 1(x+4) = (x^2 + 4x) - (x+4)

                = x^2 +4x -x -4   = x^2 +3x -4

which is a parabola
