(a) 1.6
(b) 14
(c) 18
(d) 20

The value of Z , the slope of the line ( regression coefficient ) is …..... for mammals in the tropical forest of different continents. (a) 0.6 (b) 0.8 (c) 1.15 (d) 1.21

Assertion : If the species-area relationship are analysed among very large areas like the entire continents, the value of Z, i.e., slope of line in the range of 0.1 to 0.2. Reason : The value of Z, i.e., slope of line of species area relationship lies in the range of 0.6 to 1.2 when analysis is done among small areas.

The ratio of lateral surface area to the total surface area of a cylinder with base diameter 1.6 m and height 20 cm is (a) 1\ :7 (b) 1\ :5 (c) 7\ :1 (d) 5\ :1

Show the following numbers on the number line. (a) 0.2 (b) 1.9 (c) 1.1 (d) 2.5

The relation between species richness and area is described on a logarithmic scale by the equation [where S = species richness, A = area, Z = slope of the line (regression coefficient ), C= Y - intercept]

If (2,-3), (6,-5) and (-2,1) are three consecutive verticies of a rohmbus, then its area is (a) 24 (b) 36 (c) 18 (d) 48

If y=f(x) makes positive intercepts of 2 and 1 unit on x and y-coordinates axes and encloses an area of 3/4 sq unit with the axes, then int_0^2 x f'(x)\ dx , is

The relation between specises richness and area is described on a logarithmic scale by the equation [where S = species richness, A = area, Z = slope of the line (regression coefficient ), C= Y - intercept]

If the regression equation of y on x is -2x + 5y= 14 and the regression equation of x on y is given by mx-y + 10= 0 . If the coefficient of correlation between x and y is (1)/(sqrt10) , then the value of m is

The area (in sq. units) of the quadrilateral formed by the tangents at the end points of the latus rectum to the ellipse (x^(2))/(9)+(y^(2))/(5)=1 is (a) 27/4 (b) 18 (c) 27/2 (d) 27
