Amanda got more questions correct.
<u>Step-by-step explanation:</u>
Given:
Amanda got of the questions correct.
Joe got 75% or of the questions correct.
To Find:
Individual with maximum number of correct question.
Solution:
Now we have to convert fraction and percent into a decimal number, so that we can compare it.
= 0.8
= 0.75,
Thus from the above obtained decimal details we can conclude that Amanda got more questions correct.

Step-by-step explanation:
1
Given
2x² - 16 = 0 ( add 16 to both sides )
2x² = 16 ( divide both sides by 2 )
x² = 8 ( take the square root of both sides )
x = ± = ± 2
------------------------------------
2
Given
- 5x² + 9 = 0 ( subtract 9 from both sides )
- 5x² = - 9 ( divide both sides by - 5 )
x² = ( take the square root of both sides )
x = ± = ±
-----------------------------------------
3
Given
6x² - 15 = 27 ( add 15 to both sides )
6x² = 42 ( divide both sides by 6 )
x² = 7 ( take the square root of both sides )
x = ±
