Constructing a perpendicular to a line from a point outside it..

To construct a perpendicular to a line from a point outside it A line AB and a point O outside it. It is required to construct a perpendicular to AB from O. (i) With O as centre, taking any suitable radius, draw an arc to cut AB at S and T. (ii) With S and T as centres and same ..

Construction - 17 - Given the perimeter and the base angles, to construct the triangle In the perimeter = 7.5 cm, and (1) Draw XY = 7.5 cm. (2) At X make an angle ..

Construction - 1 - To construct an angle equal to a given angle and a point Q on a line PQ. An angle equal to at Q. (i) With B as centre and any suitable radius draw an arc to cut AB at D and BC at E. (ii) With Q as centre and the same radius, draw an arc to cut PQ at ..

So far, we have assumed that the elementary events are equally likely and we have used the corresponding definition of probability. However the same definition of conditional probability can also be used when the elementary events are not equally likely. This will be clear from the following examp..

The frequency distrubution table shown here is incorrectly constructed. State the reason. Class Frequency 7 - 12 3 13 - 18 1 19 - 24 4 25 - 30 6 31 - 36 2 => The upper and lower class limits should be even numbers. or The class width should be an odd number. or The upper class l..

Based on a sample of 150 students at a university, it was found that 112 of those students walk or use bike to travel to university. Construct a 95% confidence interval for p , the proportion of all students who use bike or walk to school. => 71.5% < p < 78.5% or 70% < p < 80%..

The distance traveled (in thousands of kilometers) by female drivers in an year is as recorded. Distance traveled Number of females (Frequency) 2 0 4 4 6 7 8 18 10 24 12 27 14 14 16 6 Construct a frequency polygon and find the mean. => graph 2 and 14.69 or graph 2 and 10.58 or g..
