The correct Answer is:
To determine which central tendency value the batsman will project for selection in the cricket team for a tournament, we will calculate the mean of the runs scored by the batsman in the given matches. ### Step-by-Step Solution: 1. **List the Runs Scored**: The runs scored by the batsman in the matches are: \[ 65, 32, 97, 0, 32, 160, 68, 23, 35, 75, 40 \] 2. **Count the Number of Observations**: Count the total number of matches (observations): \[ \text{Number of observations} = 11 \] 3. **Calculate the Sum of Runs**: Add all the runs together: \[ 65 + 32 + 97 + 0 + 32 + 160 + 68 + 23 + 35 + 75 + 40 \] Let's break it down: - \( 65 + 32 = 97 \) - \( 97 + 97 = 194 \) - \( 194 + 0 = 194 \) - \( 194 + 32 = 226 \) - \( 226 + 160 = 386 \) - \( 386 + 68 = 454 \) - \( 454 + 23 = 477 \) - \( 477 + 35 = 512 \) - \( 512 + 75 = 587 \) - \( 587 + 40 = 627 \) Thus, the sum of runs is: \[ \text{Sum} = 627 \] 4. **Calculate the Mean**: The mean is calculated by dividing the sum of runs by the number of observations: \[ \text{Mean} = \frac{\text{Sum}}{\text{Number of observations}} = \frac{627}{11} \] Performing the division: - \( 11 \) goes into \( 62 \) five times (since \( 11 \times 5 = 55 \)), leaving a remainder of \( 7 \). - Bring down the \( 7 \) to make \( 77 \). - \( 11 \) goes into \( 77 \) seven times (since \( 11 \times 7 = 77 \)), leaving a remainder of \( 0 \). Therefore, the mean is: \[ \text{Mean} = 57 \] 5. **Conclusion**: The central tendency value that the batsman will project for selection in the cricket team is the mean, which is: \[ \text{Mean} = 57 \]

Two sinusoidal waves in a string are defined by the function y_(1)=(2.00 cm) sin (20.0x-32.0t) and y_(2)=(2.00 cm) sin (25.0x-40.0t) where y_(1), y_(2) and x are in centimetres and t is in seconds.

The most important use of studying nuclear fission and fusion process was to harness nuclear energy for useful purpose of humanity. Nuclear reactor is the machine designed to harness nuclear energy to electricity. The basic principle involved is fission of uranium to krypton and barium by slow moving neutrons as in following ""_(0)n^(1)+""_(92)^(235)Uto""_(32)^(96)Kr+""_(56)^(141)Ba+3_(0)n^(1)+Q(200MeV) reaction: But the difficulty is that one neutron striking with ""_(92)^(235)U produces three (2.6 on an average) neutrons which can cause further fission The neutron intensity available for further fission is controlled by measuring reproduction factor defined as the average number of neutrons from each fission the causes further fission. Maximum value of K 2.6. For optimum operation of nuclear reactor, the value of Kis mentioned in Column-1 for various stages in Columu-Il match the correct columns : {:("Column-I","Column-II"),((A)K=1,(p)"Uncontrolled chain reaction"),((B)Klt1,(q)"Critical"),((C)Kge1,(r)"Sub critical"),((D)K~~25,(s)"Super critical"):}
