Answer anybody please

  20/41

Step-by-step explanation:

The total of all students is ...

  7 + 2 + 5 + 6 + 3 + 4 + 6 + 8 = 41

The total of students not studying chemistry is ...

  7 + 2 + 5 + 6 = 20

Then the probability that a randomly-chosen student does not study chemistry is ...

  p(not studying chem) = 20/41

could you reply to this with the question so i can ?

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
