Answer:

86.86

Step-by-step explanation:

Another word for mean is average.  To find the mean or average, we add up all the numbers and then divide by the number of numbers

There are 7 scores

Mean = (88+91+89+94+90+64+ 92)/7

         = 608/7

         =86.85714286

To 2 decimal places ( we have to round to be accurate to 2 decimal places)

         86.86

<h3>The length of legs of isosceles right triangle is 8.5 cm</h3>

<em><u>Solution:</u></em>

Given is a isosceles triangle

hypotenuse = 12 cm

In an isosceles right triangle, the legs have equal lengths

Let these sides be each  "a" cm

By pythogoras theorem,

(Hypotenuse)^2  =  (leg)^2  +  (leg)^2\\\\12^2 = a^2+a^2\\\\2a^2 = 144\\\\a^2 = 72\\\\Take\ square\ root\ on\ both\ sides\\\\a = \sqrt{72}\\\\a = 8.49 \approx 8.5

Thus the length of leg of  isosceles right triangle is 8.5 cm
