The image is not very much enlarged, and is slanted, so answers might be just approximate.
(a) median is 39 or 40, your choice.
(b) 3rd quartile of y looks 47 or 48
(c) variable y has more disperson, since both the extremes and the quartiles are spread out longer that those of variable x.
(d) since both halfs of the blue box (of x) and both lines outside of the box are basically equal, variable x's distribution is very much symmetric.
Sorry, cannot read question part (e) completely.
(3x/4) = 21
/3 /3 divide 21 by 3
(x/4) = 21/3 = 7
(x/4) = 7
*4 *4 multiply 7 by 4
x = 7*4 = 28
answer = 28
I think it is D
Hope my answer help you?
Let length of base be x and breadth of base be y
2x + 2y = 28
x + y = 14
y = 14 - x
Volume of box
= 5xy
= 5x (14 - x)
= 70x - 5x^2

<u>Biquadratic Equations</u>
Solve:
The biquadratic equations are equations of degree 4 without the terms of degree 1 and 3.
Solving such equations requires to express the equation as a second-degree equation with as the variable.
Rewriting the equation:
The quadratic equation can be factored as:
It leads to two equations:
The first equation has imaginary roots. Solving for x:
Where
The second equation has two real roots:
The roots are:
