Answer:
x=6, 9, 10, 20, 22, 25, 27, 40 , 48, 59
i= 1, 2 , 3, 4, 5, 6, 7, 8, 9, 10
And as we can see here the position for x=40 is 8, so then we can calculate the percentile for 40 grams like this:
So the the vale of 40 gr correspond to the 80th percentile of the data since accumulates 80% of the values below.
Step-by-step explanation:
We can define a percentile as "a value on a scale of 100 that indicates the percent of a distribution that is equal to or below it"
For this case we have the following data given:
6 , 9, 10, 20, 22, 25, 27, 40 , 48, 59
And we want to calculate the percentile for the value of 40 grams
Since the dataset is on increasing way there is no problem to calculate this percentile.
We see that we have a total of n =10 observations, and we can rank the position of each observation (i) like this:
x=6, 9, 10, 20, 22, 25, 27, 40 , 48, 59
i= 1, 2 , 3, 4, 5, 6, 7, 8, 9, 10
And as we can see here the position for x=40 is 8, so then we can calculate the percentile for 40 grams like this:
So the the vale of 40 gr correspond to the 80th percentile of the data since accumulates 80% of the values below.
Answer and explanation:
1. 9:12 or or 9 to 12
It has 9 first because there are 9 lions and then 12 after because there are 12 elephants.
2. 8:16 or or 8 to 16
It has 8 first because there are 8 giraffes and then 16 after because there are 16 otters.
3. 9:10 or or 9 to 10
It has 9 first because there are 9 lions and then 10 after because there are 10 seals.
4. 10:12 or or 10 to 12
It has 10 first because there are 10 seals and then 12 after because there are 12 elephants.
5. 12:9 or or 12 to 9
It has 12 first because there are 10 elephants and then 9 after because there are 9 lions.

I just multiplied it first the first one by 2, second one by 10, and 3rd one by 4.
7. or
or
I just simplified it first, then I multiplied the simplified one by 6 for the second one, and for the 3rd one I multiplied the simplified by 10.
8. or

I just simplified it first, then I multiplied the simplified one by 2 for the second one, and for the 3rd one I multiplied the simplified by 10.
9. 3:4 is equivalent to 6:8, 30:40, 12:16
I multiplied it first by 2, then by 10, then by 4.
10. 5:7 is equivalent to 10:14, 50:70, 25:35
I multiplied it first by 2, then by 10, then by 5.
11. 9:2 is equivalent to 18:4, 90:20, 27:6
I multiplied it first by 2, then by 10, then by 3.

a. 48
So first, the ratio we know is 5:4 which in other words is 5x:4x. We also know that there are 60 clownfish. So that means 5x = 60 --> x = 12. So then 4x has to equals 12 x 4 which is 48.
b. 36
So first, the ratio we know is 4:3 which in other words is 4x:3x. We also know that there are 48 angelfish. So that means 4x = 48 --> x = 12. So then 3x has to equals 12 x 3 which is 36.
