Which statement is true about the parts of this expression? 7.5y - z/9 + 50 +2ya) the constant is 7.5.b) the coefficients are 7.5 and  -9.c) the variables are  x  and  y. d) the like terms are  7.5y  and  2y.

A) The constant is 7.5.  FALSE.  7.5 is a coefficient, not a constant.

B) The coefficients are 7.5 and -9.  FALSE.  The coefficients are 7.5, -1/9 and 2.  50, being a constant, could be regarded as a coefficient in this case.

C) The variables are x and y.  FALSE.  There are three variables:  x, y and z.

D) The like terms are 7.5y and 2y.  TRUE.  The variable (y) is the same in each term.

Ifound this on google “a skewed (non-symmetric) distribution is a distribution in which there is no such mirror-imaging. a "skewed right" distribution is one in which the tail is on the right side. a "skewed left" distribution is one in which the tail is on the left side. the above histogram is for a distribution that is skewed right.” i hope this you for what your looking for
