A definition of a common ration Is the number multiplied must be the same for each term in the sequence. The common ratio is the amount between each number in a geometric sequence. To determine the common ration you can just divide each number from the number preceding it in the sequence. Here is an example I found of a common ration to further help you
2,4,8,16
16/8=2 you would then continue to divide to ensure that the pattern is the same for each number
8/4=2
4/2=2 the ratio is the same for each one so the common ration would be 2 I hope this helps could I please get a brainliest :)
Using the Empirical Rule, it is found that the proportion of people in a population with IQ scores between 80 and 140 is of 0.95 = 95%.
<h3>What does the Empirical Rule state?</h3>
It states that, for a normally distributed random variable:
- Approximately 68% of the measures are within 1 standard deviation of the mean.
- Approximately 95% of the measures are within 2 standard deviations of the mean.
- Approximately 99.7% of the measures are within 3 standard deviations of the mean.
Considering the mean of 110 and the standard deviation of 15, we have that:
These values are both the most extreme within 2 standard deviations of the mean, hence the proportion of people in a population with IQ scores between 80 and 140 is of 0.95 = 95%.

Given B = {a, l, g, e, b, r} and C = {m, y, t, h}, find B ∪ C. {} {a} {a, b, e, g, h, l, m, r, t, y}

1. A ∪ B = { x | x ∈ A or x ∈ B} ==> Ans C.
<span>2. B ∪ C = { x | x ∈ B or x ∈ C} ==> Ans C</span>
I believe it should have 6 turning points.
Hope this helped
Answer:
B) 15.7
Step-by-step explanation:
AB = 6
BC = 3
AC^2 = 6^2 + 3^2 = 36 + 9 = 45
AC = √45 = 6.7
Perimeter = AB + BC + AC
= 6 + 3 + 6.7
= 15.7
