Aresearcher is interested in determining whether smiling and warmth impact the number of friends one has. amount of smiling (a little, a lot) and self-rated warmth (cold, warm) are each two-level variables. this experiment has how many conditions?

Consider this equation. |y + 6| = 2 what can be concluded of the equation? check all that apply. there will be one solution. there will be two solutions. the solution to –(y + 6) = 2 will be also be a solution to the given absolute value equation. the solution(s) will be the number(s) on the number line 2 units away from –6. the value of y must be positive since the variable is inside absolute value signs.
