Answer: part A- 2.5(7.5+7.5+7.0) part B -(55

Step-by-step explanation:

Answer 2

The expression to obtain Tyrell's score is 2.5(7.5 + 7.5 + 7.0) while Tyrell's score is 55

The judges score are given below :

8.0, 7.5, 6.5, 7.5, and 7.0

Expression to find Tyrell's score :

Highest score = 8.0

Highest score = 8.0Lowest score = 6.5

The raw score = sum of the judges score after dropping the highest and lowest scores :

The raw score value = (7.5 + 7.5 + 7.0) = 22.0

Expression to find Tyrell's score :

Degree of difficulty × Raw score

Degree of difficulty = 2.5

Expression = 2.5(7.5 + 7.5 + 7.0)

Tyrell's score = 2.5(7.5 + 7.5 + 7.0) = 2.5(22.0) = 55
