Respuesta :

Answer:

6% of the changes were from incorrect to​ incorrect

Step-by-step explanation:

The sum of the percentages must be 100%.

We have these following percentages

65​% of the changes were from incorrect answers to correct

29​% were from correct to incorrect

P% were from incorrect to incorrect

So

[tex]65 + 29 + P = 100[/tex]

[tex]P = 100 - 94[/tex]

[tex]P = 6[/tex]

6% of the changes were from incorrect to​ incorrect
