The following tables gives the height and weight of 10 friends what is the correlation coefficient for the data?

0.673 or 0.67

Step-by-step explanation:

To calculate correlation coefficient of the data. We can use the following formula.

Here 'x' represents the height and 'y' represents the weight.

Finding the individual values and putting them into the equation above we get,

r = 0.673

Therefore, the correlation coefficient of the given data is 0.673 or 0.67 (rounded to the nearest hundredth).

(1,4) is on graph of f(x)

f(1) = 4

so 1/4 f(x)

1/4 f(1)

1/4. ×4

1

so point for function 1/4. f(x) is (1,1)

4 + 5 7/9= 9 7/9
