Question
For the purposes of the survey, only (a)/ the margin of
error may be substantial(b)/3% of rural households were surveyed by the agencyfor (c)/it is important to note that (d)/the updated numbers and so (e). In the questions, the sentence is split into five parts. These parts are not given in their proper order. Read the sentence and find out which of the five combinations is correct.Solution
Only option 3 makes sense. It is important to note that for the purposes of the survey, only 3% of rural households were surveyed by the agency for the updated numbers and so the margin of error may be substantial.
If 0 ≤ θ ≤ 90°, and sin(2 θ +50°) = cos (4 θ + 16°), then what is the value of θ (in degrees)?
sin10˚ x sin20˚ x sin40˚ =?
If (2sin A + cos A) = 3sin A, then find the value of cot A.
If tan 4θ = cot 14θ, then find the value of cos 9θ.
If sin A = 3/5 and cos B = 4/5, where A and B are acute angles, find the value of sin(A + B).
If √3cosec 2x = 2, then the value of x:
If tan θ + cot θ = 2 where 0 < θ < 90 ; find the value of tan30 θ + cot 29 θ.
- If sin (3A − 4B) = (1/2) and cos (A + B) = (√2/2), where 0° < A, B < 90°, then find the value of ‘A’.
If θ is an acute angle and sin θ + cosec θ = 2, then the value of sin2 θ + cosec2 θ is:
