Write an equation of the line which passes through the points (8, - 9) and (- 10, 11) in standard form using integer coefficients. => 10 x - y = 9 or 10 x - 9 y = - 1 or x + 9 y = 10 or 10 x + 9 y = - 1..

Write an equation of the line which passes through the points (4, - 6) and (- 7, 8) in standard form using integer coefficients. => 14 x + 11 y = - 10 or ( y + 6) = - 14 11 ( x - 4) or 1 2 x + y + 8 = 0 or 14 x + 11 y - 10 = 0..

Which of the following statement(s) is/are true? I. The multiple correlation coefficient denoted by R takes into account all the independent variables and can be computed by using the values of the individual correlation coefficients. II. R can range from - 1 to + 1. I..

It has very low co-efficient of expansion and can withstand sudden changes in temperature. Therefore highly suitable for laboratory ware like flasks, beakers and oven proof cook ware..

The correlation coefficient for the age and blood pressure of 4 people taken randomly is given. Find t and test the significance of correlation coefficient r = 0.9478, use ∝ = 0.01 and n = 4. => 4.2, significant relationship or 1.2, no significant relationship or ..

Which of the following statement(s) is/are true? I. If the correlation coefficient is significant, the equation of the regression line cannot be determined. II. The values of the dependent variable can be predicted for the values of the independent variable using the regression ..

The formula for the F test used to test the significance of the multiple correlation coefficient R using n the number of data sets and k the number of independent variables and d.f. N = n - k , d.f. D = n - k - 1 is => R 2 ( n - k ) 1 - R 2 ( n - k - 1 ) or 1 - R 2 ( n..

In this chapter, we shall study two series known as the Exponential series and Logarithmic series. In our discussion, we shall make use of mathematical tools like formula for sum of an infinite G.P., combinatorial coefficients..

Usually a polynomial is denoted by P(x) and if k is any number then P(k) denotes the value of P(x) at x=k. Then a polynomial can be used to define a function with x or y or any letter of the alphabet. The coefficient of the polynomial may belong to any system of number..
