Agardener wants to compare the heights of plants in two gardens that are watered using different tools. the heights, in centimeters, for a group of plants in the two gardens are shown.
plant heights (cm) in garden a: 15, 17, 17, 19, 19, 20, 21, 22, 22, 22, 22, 23, 23, 24, 24, 24, 26, 28, 29, 29, 30
plant heights (cm) in garden b: 10, 20, 20, 20, 21, 21, 21, 22, 23, 24, 25, 25, 25, 25, 26, 26, 26, 27, 30, 31, 32
what is the best measure of center for comparing the two data sets and what comparison can be drawn?

Garden A: 24.05cm ( add all the numbers(=457)and divide by the amount of numbers (19))

Garden B: 22.85cm ( add all numbers (=480) divide by amount of numbers (21))

something that characterises a right triangle is the fact that we may use pythagoras' theorem to find any one of its sides given that we have the length of the other two sides. here, we have the length of the hypotenuse, √(87) yd, and one other side, √(23) yd, thus we can easily find the length of the remaining side using pythagoras' theorem as defined below:

c^2 = a^2 + b^2, where c is the length of the hypotenuse, and a and b are the lengths of the other two sides.

thus, given that c = √(87) and a = √(23), we may substitute these into the formula we defined above to get:

c^2 = a^2 + b^2

(√87)^2 = (√23)^2 + b^2 (substitute c = √87 and a = √23 into the equation)

87 = 23 + b^2 (evaluate (√87)^2 = 87 and (√23)^2 = 23 - remember that the square root of a number, squared will equal that very same number)

64 = b^2 (subtract 23 from both sides)

√64 = b (take the square root of both sides)

8 = b (evaluate √64 = 8)

therefor, the length of the unknown leg in the right triangle is 8 yd (first answer).
