The table shows the heights and weights of a few students in a class. height (inches) weight (pounds)
height weight
58 122
59 128
60 126
62 133
63 145
64 136
66 144
68 150
70 152
complete the following sentences based on your observations. the data seems to have a correlation coefficient close to . this indicates that the weight of a student as the height of the student increases.

Correlation coefficient = 0.945 ( approx) and weight of a student increases as the height of the student increases.

Step-by-step explanation:  

Here, value of x are   58, 59, 60, 62, 63, 64, 66, 68, 70

Value of y are,     122, 128, 126, 133, 145, 136, 144, 150, 151.

∑x = 570, ∑y= 1236, ∑ = 36234, ∑ = 170694

∑xy=78617

Thus the correlation coefficient,

Where n is the number of the term.

here n = 9

thus, correlation coefficient

r =

Thus, r= 0.94452987512

Which is closed to 0.95 and greater than 1

Therefore, weight of a student increases as the height of the student increases.

his first public project he is asked to create a small scale drawing. the garden is a right triangle with base 25m and height 30m. are you trying to solve for the last side/hypotenuse? the irrational form of the answer would be 5\sqrt{61}

14 x 10 5

step-by-step explanation:

10 5 = 100,000

14x10,000 = 140,000
