12 houses in a residential area were under construction and each house has 11 construction workers. In how many different ways can a worker be chosen? => 144 or 127 or 132 or 142..

Age in years of twenty secondary school students visiting the zoo on a week day were recorded. The results were : 12, 16, 10, 19, 17, 10, 10, 11, 11, 11, 11, 12, 12, 11, 12, 13, 12, 14, 15, 18 Construct an ogive and find the median age and..

To bisect an angle , we are required to bisect (i) With B as centre and any suitable radius draw an arc to cut AB at D and BC at E respectively. (ii) Take any radius greater than of ED, not necessarily the previous radius. (iii) With this radius, taking points D and E as centres, draw two arcs whic..

Water flowing in high altitude rivers is stored in a man-made reservoir as shown in the figure. The kinetic energy of the flowing water is transformed into potential energy as the water level rises. This water is carried through pipes to the turbine situated at the bottom of the dam. The water ..

The probability of constructing a bridge in one year is 45%. What are the odds in favor of constructing it in one year? => 2 2 11 or 9 11 or 2 11 or 1 2 11..

The cumulative frequency for the distribution of the distance (in miles) that 20 randomly selected runners ran during a week is given in the ogive. Find the interquartile range for the data by constructing a box plot. => 18.5, Figure 2 or 11.2, Figure 2 or 23.5, Figure 1 or 12, ..

If an angle of any measure be given, one can always construct (or draw) a cartesian co-ordinate reference frame in such a way that the origin is at the vertex of the angle, and positive half of the x axis coincides with the initial side of the angle. When this has been achieved, the angl..

Ratio of Intensities at Maxima and Minima - It has already been proved that the intensity of a wave is proportional to the square of the amplitude. At a point where constructive interference has occurred, the intensity will be maximum and the amplitudes of the two waves will have added. I..

The branch of physics dealing with measurement of temperature is called thermometry. A number of physical properties of a substance change almost linearly with temperature. This forms the basis or principle for construction of thermometers. Different scales of temperatures have been adop..
