The player needs 5 consecutive hits in order to raise his 2010 batting average to that of 2011.
An average of a list of data is the expression of the central value of a set of data. It is also defined as the ratio of summation of all the data to the number of units present in the list.
It is given that a professional player had 123 hits and 501 at-bats in 2010 and in 2011, he had 131 hits and 515 at-bats.
Also, the baseball player's batting average is equal to the number of hits divided by the number of at-bats.
Average in 2010 - 123/501 = 0.245 .
Average in 2011 - 131/515 = 0.254 .
Thus if he increases the number of shots to 5 then we have the total number of shots as 123 + 5 = 128 .
Therefore the batting average for 2010 becomes - 128/501 = 0.255 which matches the batting average of 2011.
Thus, the player needs 5 consecutive hits in order to raise his 2010 batting average to that of 2011.
