83 is a whole number and cannot be simplified.
Given:
must correctly answer 80% of the questions
correctly answered questions = 26
incorrectly answered questions = 4
unanswered questions = 15
Total questions = 26 + 4 + 15 = 45
45 * 80% = 36 required correctly answered questions.
36 - 26 = 10
Out of 15 remaining questions, 10 questions must be correctly answered for Heidi to advance to the next level.
(-1.15)x3.2=
-3.68
Alright so I got -3.68 by multiplying -1.15x3.2. We get a negative number since the first number is negative.
