Answer:
The answer is 16 ÷ 2 = 8.
Step-by-step explanation:
Now, to find the expression modeled by arrangement of tiles.
So, according to the model in the question.
There are 16 tiles in the model.
So, arrangement of 16 tiles divided into 2 groups.
Where each group consist 8 tiles.
So, we can write as:
As 16 is the number of tiles and 2 is the number of groups.
Now, we can check the expression by doing the division.
Therefore, each group has 8 tiles.
The answer is:
1- A line of symmetry will connect a vertex and a midpoint of an opposite side.
2- It has -fold symmetry.
The explanation for this answer is shown below:
1- By definition, a line of symmetry is an imaginary line that divides a figure into two equal images or equal halves. If you connect a vertex and a midpoint of an opposite side of an heptagon by drawing a line, you will obtain two equal halves.
2- An heptagon has seven vertices, therefore, based on the information mentioned above, it has -fold symmetry.

Step-by-step explanation:
Generally when two fair 6-sided dice is rolled the doubles are
(1 1) , ( 2 2) , (3 3) , (4 4) , ( 5 5 ), (6 6)
The total outcome of doubles is N = 6
The total outcome of the rolling the two fair 6-sided dice is
n = 36
Generally the probability that doubles (i.e., having an equal number on the two dice) were rolled is mathematically evaluated as
Generally when two fair 6-sided dice is rolled the outcome whose sum is 4 or less is
(1, 1), (1, 2), (1, 3), (2, 1), (2, 2), (3, 1)
Looking at this outcome we see that there are two doubles present
So
The conditional probability that doubles were rolled is mathematically represented as
Generally when two fair 6-sided dice is rolled the number of outcomes that would land on different numbers is L = 30
And the number of outcomes that at least one die is a 1 is W = 10
So
The conditional probability that at least one die is a 1 is mathematically represented as
