Mrs. mcguffy is calculating a numerical analysis of the semester exam grades for students in her third period class. she entered the percentage correct on the exam for every student into a calculator and generated the following statisticts. which of these statements cannot be justified using statisticts shown in these two calculator screen shots?

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1

50*10 is greater

step-by-step explanation:

if you add the zero from 10 to 50, it will give you a bigger number.
