Answer 2

Answer:

Her final score in the competition will be: D) Greater than or equal to 6.25

Step-by-step explanation:

• The given scores by 1st five judges are 6.5, 7, 8, 7.5, and 6.
• Total of the score of five judges = 6.5 + 7 + 8 + 7.5 + 6

                                                             = 35

• Each of the rest three judges have given marks ≥ 5
• The minimum score given by the three judges = 15
• So total score will be = 35 + 15 = 50
• Final score must be  ≥ 50.
• Score should be in the range of 0 t0 10. To express the score in that scale we have to take the average.
• Average = total score/ 8
• Average final score ≥ (50/8) = 6.25
• Average score must be equal to or greater than 6.25.
