Practice CBSE Class 11 Statistics in the app →The relationship between degree measure and radian measure is:In a circle of radius r, an arc of length l subtends a central angle θ (in radians) such that:For all real x, the value of sin²x + cos²x is:Convert 40°20′ to radian measure.A wheel makes 360 revolutions in one minute. Through how many RADIANS does it turn in one second?The minute hand of a watch is 1.5 cm long. The distance the tip moves in 40 minutes is (use π = 3.14):The radius of a circle where a central angle of 60° intercepts an arc of length 37.4 cm (use π = 22/7) is:If two arcs of equal length subtend angles of 65° and 110° at the centres of two circles, the ratio of the radIf cos x = -3/5 and x lies in the THIRD quadrant, then sin x equals:If cot x = -5/12 and x lies in the SECOND quadrant, then sin x equals:In which quadrant is tan x POSITIVE while sin x is NEGATIVE?The DOMAIN of y = tan x is:sin(2nπ + x) equals (for any integer n):The RANGE of y = sec x is:At which of the following x-values is cos x equal to zero?The value of cos(-π/3) is:6 radians converts to approximately:An angle of $90^\circ$ in radians is:The value of $ in(\pi/4)$ is:The identity $ in 2A$ equals:The general solution of $\cos x = 1/2$ is:The angle 90° in radians is:The fundamental Pythagorean identity in trigonometry is:The exact value of cos 60° is:The double angle formula sin 2A equals:The general solution of sin θ = 1/2 is:The principal value range of sin⁻¹(x) is:In a triangle ABC, the Law of Sines states:The Law of Cosines, given sides a, b and included angle C, gives the third side c as:The function f(x) = tan x has vertical asymptotes at:Measures of central tendency alone give information that is:Besides central tendency, the other factor studied in statistics is:A single number describing the variability of data is a measure of:Which of these is listed as a measure of dispersion?How many measures of dispersion are listed?The measure of dispersion NOT studied in this treatment is the:The range of a series is the maximum value minus the:The range gives an idea of variability that is only:The range does not tell about dispersion from a measure of:The deviation of an observation x from a fixed value a is:The sum of deviations of observations from their mean is always:Because signs cancel, the sum of deviations from the mean may:Mean deviation about the mean is described as not very:Mean deviation is calculated using values of deviations that are:Using absolute values means mean deviation cannot be given further:The measure introduced to overcome the drawbacks of mean deviation is:Mean deviation and standard deviation have the same units as the:A measure of variability independent of units is the coefficient of:The coefficient of variation is useful for comparing series measured in:In the batting example, batsman A had a range of:A larger range means the scores are more:Standard deviation is a measure of:
