the following data values represent a sample. what is the variance of the sample? x=9. use the information in the table to help you

Step-by-step explanation:

Variance of X = 9

Regression equations are

(*) 8x −10y + 66 = 0

(**) 40x −18y − 214 = 0

Find out the following missing results.

(i) The means of X and Y

(ii) The coefficient of correlation between x and y

(iii) The standard deviation of Y

in mathematics, a function is a relationship between two variables such that the value of one of the variables, called the dependent variable, is determined by the value of the other variable, called the independent variable. there is a specific term we use to describe the set of independent variables of a function.

= 5

step-by-step explanation:

to find the 15th term substitute n = 15 into the nth term formula

= (- 3 × 15 ) + 50 = - 45 + 50 = 5
