Respuesta :
91 m0re points an 360/4 is 90 so total points needed is 360 the subtract 360 by 269 and get 91
The points must he score on the fourth test is should be greater than 91 .
What is average ?
The average is defined as the mean value which is equal to the ratio of the sum of the number of a given set of values to the total number of values present in the set.
According to the question
Let Jake's 4 math tests = M1 , M2 , M3 , M4
Jake scored 269 points on three math tests.
i.e
M1 + M2 + M3 = 269
Average number of points on four tests must be no less than 90
i.e
By using formula of Average
Average = [tex]\frac{Sum of total observations }{number of total observations}[/tex]
90 < [tex]\frac{M1+M2+M3+M4 }{4}[/tex]
360 < 269 + M4
91 < M4
Therefore
M4 should be greater than 91 .
Hence, the points must he score on the fourth test is should be greater than 91 .
