The length of 40 leaves of a plant are measured correct to one millimetre, and the obtained data is represented in the following table :

(iii) Is it correct to conclude that the maximum number of leaves are 153 mm long ? Why ?

The length of 40 leaves of a plant are measured correct to one millimetre, and the obtained data is represented in the following table : (ii) Is there any other graphical representation for the same data ?

The length of 40 leaves of a plant is measured correct to the nearest millimetre and the data obtained is represented in the following table. Find the mean length of the leaves.

The lengths of 40 leaves of a plant are measured correct to the nearest (millimeter, and the data obtained is represented in the following table Find the median length of the leaves. (Hint: The data needs to be converted to continuous classes for finding the median, since the formula assumes continuous classes. The classes then change to 117.5-126.5,126.5-135.5,...,171.5-180.5.)

An insurance company selected 2000 drivers at random (i.e., without any preference of one driver over another) in a particular city to find a relationship between age and accidents. The data obtained is given in the following table: Find the probabilities of the following events for a driver chosen at random from the city: (i) The driver being in the age group 18-29 years and having exactly 3 accidents in one year. (ii) The driver being in the age group of 30-50 years and having one or more accidents in a year. (iii) Having no accidents in the year.

Correct the following statements and rewrite them in your notebook. Leaves hold the plant upright.

One end of a string of length l is connected to a particle of mass m and the other to a small peg on a smooth horizontal table. If the particle moves in a circle with speed v the net force on the particle (directed towards the centre) is : (i) T, (ii) T - (mv^2)/(l) , (iii) T + (mv^2)/(l) , (iv) 0 T is the tension in the string. [Choose the correct alternative].
