The sample space is any space that gives a positive outcome to all samples. They have to have an equal outcome
It should be noted that the rotation symmetry that an equilateral triangle has is 3.
<h3>What is rotational
symmetry?</h3>
It should be noted that rotational symmetry simply means when an object is rotated on its own axis.
In this case, it should be noted that the rotation symmetry that an equilateral triangle has is 3.
Also, the number of degrees that you can rotate the shape to carry it onto itself will be 60°, 120°, and 180°.

Answer:
For 2017 Season:
Mean = 75
Standard deviation = 2.07
For 2018 Season:
Mean = 75
Standard deviation = 5.26
Step-by-step explanation:
The following formulas will be used in these calculations:
Mean = (sum of the values) / n
Variance = ((Σ(x - mean)^2) / (n - 1)
Standard deviation = Variance^0.5
Where;
n = number of values = 8
x = each value
For 2017 Season
Mean = (73 + 77 + 78 + 76 + 74 + 72 + 74 + 76) / 8 = 600 / 8 = 75
Variance = ((73-75)^2 + (77-75)^2 + (78-75)^2 + (76-75)^2 + (74-75)^2 + (72-75)^2 + (74-75)^2 + (76-75)^2) / (8-1) = 30 / 7 = 4.29
Standard deviation = Variance^0.50 = 4.29^0.5 = 2.07
For 2018 Season
Mean = (70 + 69 + 74 + 76 + 84 + 79 + 70 + 78) / 8 = 75
Variance = ((70-75)^2 + (69-75)^2 + (74-75)^2 + (76-75)^2 + (84-75)^2 + (79-75)^2 + (70-75)^2 + (78-75)^2) / (8-1) = 194 / 7 = 27.71
Standard deviation = Variance^0.50 = 27.71^0.5 = 5.26
The prime factorization is ...
... 2²×3×7×11
Single-digit prime factors are ... 2, 3, 7
Single-digit divisors are ... 1, 2, 3, 4, 6, 7
Answer:
it's can't be factorise because there is nothing common in them simply.
