The two-way table is attached.
We know that 63 people took the survey, and 22 of them were left-handed. This means that 63-22=41 of them are right handed.
Out of the 63 total, 37 are left brain dominant; this means that 63-37=26 are right brain dominant.
Of the 26 that are right brain dominant, 21 are right handed; this means 26-21=5 are left handed.
Of the 22 left-handed people, 5 are right brain dominant; this means 22-5 = 17 are left brain dominant.
Of the 37 left brain dominant people, 17 are left handed; this means 37-17=20 are right handed.

Where a is the side
We are given an area o square =
So,
4. We are given that the solution of quadratic equation -9 and 9
So, equation becomes:
So, in the given equation
z should be the number from which if we subtract 103 so we get 81
Substitute z = 22
Thus the value of z is 22
