Divers in a competition are scored by an international panel of judges. The highest and the lowest scores are dropped. The total
Luden [163]

Let

x--------> the degree of difficulty of the dive


we know that

1) The highest and the lowest scores are dropped

so

highest scores=8.5

lowest scores=6.5


the remaining scores=[7.5, 8.0, 7.0, 7.5, 7.0]


2) Find the total of the remaining scores

=[7.5+8+7+7.5+7]\\ =37


3) The total of the remaining scores is multiplied by the degree of difficulty of the dive

so

37*x


4) This product is multiplied by .6 to determine the final score

[37*x]*0.6=77.7\\ 22.2*x=77.7\\ x=3.5


therefore


the answer is

the degree of difficulty of the dive is 3.5
