Answer:
Yes!
Step-by-step explanation:
I know this from having been a bank teller. But let's examine the math.
Any two digit number can be written as 10x + y.
Reverse the digits would give you
10y + x
Subtract to find the difference.
10x + y - (10y + x)
10x + y - 10y - x
10x - x - 10y + y
9x - 9y
9(x - y)
Yes, it has 9 as a factor, so it is a multiple of 9.
If there are 13 letters typed, the probability that no letters will be repeated can be found to be 1.05 x 10⁻²⁰
<h3>How to find the probability no letters are repeated?</h3>
First, find the number of possibilities of 13 letters from 26 letters in the alphabet as:
= 26 x 26 x 26 x 26 x 26 x 26 x 26 x 26 x 26 x 26 x 26 x 26 x 26
= 6.156 x 10³⁶ possibilities
If the numbers are not to be repeated then the possibilities are:
= 26 x 25 x 24 x 23 x 22 x 21 x 20 x 19 x 18 x 17 x 16 x 15 x 14
= 64764752532480000 possibilities
The probability that no letters are repeated is:
= 64764752532480000 / 6.156 x 10³⁶
= 0.0000000000000000000105
= 1.05 x 10⁻²⁰

The range is the y-values. Here is the answer and explanation :)
Answer:
HW → CT
∠ X → ∠ S
∠ D → ∠ L
DW → LT
Step-by-step explanation:
The quadrilateral DXHW is similar to quadrilateral LSCT.
So, side HW of the quadrilateral DXHW matches with the CT side of the quadrilateral LSCT.
And angle ∠ X of the quadrilateral DXHW matches with the angle ∠ S of the quadrilateral LSCT.
Again, angle ∠ D of the quadrilateral DXHW matches with the angle ∠ L of the quadrilateral LSCT.
Finally, side DW of the quadrilateral DXHW matches with the LT side of the quadrilateral LSCT. (Answer)
