Jim must get ≥ 78 score to maintain his average ≥ 90 .
Every thing has a central tendency , Average is one of the measure of Central Tendency.
It is the mean of all the given numbers and is determined by summing all the numbers or data and then dividing by the total number of data.
It is given that
Jim has gotten scores of 99 and 93 on his first two tests.
He has to maintain an average of 90 or greater
The third test score = ?
Average = (99+93+x)/3
90≤ (99+93+x)/3
270 ≤ (99+93+x)
270 ≤ 192 + x
Therefore x ≥ 78
Jim must get ≥ 78 score to maintain his average ≥ 90 .

9 was the square of 3. The square of -3 is 9 as well
(−3)2=(−3)⋅(−3)=9(−3)2=(−3)⋅(−3)=93 and -3 are said to be the square roots of 9.
All positive real numbers has two square roots, one positive square root and one negative square root. The positive square root is sometimes referred to as the principal square root. The reason that we have two square roots is exemplified above. The product of two numbers is positive if both numbers have the same sign as is the case with squares and square roots
a2=a⋅a=(−a)⋅(−a)a2=a⋅a=(−a)⋅(−a)A square root is written with a radical symbol √ and the number or expression inside the radical symbol, below denoted a, is called the radicand.
a√aTo indicate that we want both the positive and the negative square root of a radicand we put the symbol ± (read as plus minus) in front of the root.
±9√=±3±9=±3Zero has one square root which is 0.
