How do I graph X is greater than 7
Answers
On a Cartesian plane (a graph with one x-axis and one y-axis (an X Y graph)):
draw a DASHED line at x = 7. The dashed line means "don't include 7". This is because x must be GREATER than 7 so 7 isn't included.
Now shade everything to the right of 7 - - - so that numbers such as x = 8, x = 10, etc are shaded.
see attached screenshot.

This questions bothers permutation since permutation talks about arrangement.
The number of ways n objects can be arranged is n! ways
n! = n(n-1)(n-2)!
If a family of 5 is going on a cross-country vacation, and decided to change their seating arrangement. The total seating arrangement that they can have is;
5! = 5*4*3*2*1
5! = 20*6

Step-by-step explanation:
I will assume that the shaded region is the area in between the circle and the rectangle.
All we have to do is find the area of the circle and subtract it from the area of the rectangle.
Area of a circle is given as:
where r = radius
The radius of the circle is 1 cm, so, the area of the circle is therefore:
= 3.14 square centimetres
The area of a rectangle is given as:
A = L * B
The dimensions of the rectangle are 11 cm by 12 cm. The area of the rectangle is:
A = 11 * 12 = 132 square centimetres
The area of the shaded part is therefore:
A = 132 - 3.14 = 128.86 square centimetres
