An agricultural scientist wants to determine the effect of fertilizer type on the yield of tomatoes. The scientist sent questionnaires to 100 tomato growers. The type of fertilizer did not significantly affect the yield according to the 15 growers who responded.

Me solve this problem, and someone clearly explain to me how to solve it.1.) use the value of the discriminant to determine if the given trinomials has 2 real solutions, 1 real solution, or no real solutions. a.  x2  − 4x  − 7 = 0b. 4r2  + 11r  − 3 = 0c. 3m2  + 7 = 0d.  t2  + 2t  + 1 = 0

Me complete this proof! prove that a quadrilateral is a square. me with the steps for this proof.

The table represents a function. what is f(-2)? a.-3 b. -1 c.1 d.3
