Can i have help with the questions b and d.

Answer 1

To solve for the points score on a quiz question:

There are 25 question in a quiz

`\begin{gathered} \text{correct answer = 3 points} \\ in\text{correct answer = -2 points} \\ Not\text{ answered = 0 point} \end{gathered}`

(a) The maximum score you could get is 75

`\begin{gathered} \text{correct answer = 3points} \\ 25\text{ x 3 = 75} \end{gathered}`

(b) The minimum score you could get is -50

cause if you keep on getting the wrong answer you get -2

25*(-2) questions = -50 points

Therefore It is possible to finish the quiz with a negative score.

(c) 10 are correct question = 10*3=30 points

15-10 incorrect questions= 5 * (-2)=-10

for every untouch questions 0 points

Total points he obtained=(-10+30)= 20 points

(d) 6 are correct questions= 6*3=18 points

21-6 incorrect questions=15*(-2)=-30

for every untouch questions 0 points

Total points he obtained=(-30+18)= - 12 points

Therefore It is possible to finish the quiz with a negative score.
