Answer:
The first step on this case is order the dataset on increasing way, and after do this we got:
11 14 15 16 17 17 18 19 21
We have a sample size of n =9
And in order to find the 75th percentile we need to find the position for this percentile with this formula:

So then we can conclude that the 75th percentile would be approximately on the 7 position of the dataset ordered and we got:

Step-by-step explanation:
For this case we have the following data:
16 17 11 21 15 14 17 18 19

Answer:
1286 meters long
Step-by-step explanation:
421,808 divided by the width of the plot gives you 1,286 meters for the width.
You do the same as if it was positive you will multiply -4*-4 to get 16 and then you will multiply 16*-4 to get -64
Hope this helps
Answer:
24
Step-by-step explanation:
Volume = whl
V = 8 x 1 x 3 = 24
hope this helps and is right!! p.s. i really need brainliest :)
Answer:
6
Step-by-step explanation:
Given I varies inversely with R then the equation relating them is
I =
← k is the constant of variation
To find k use the condition R = 12 when I = 3
k = IR = 3 × 12 = 36
I =
← equation of variation
When I = 6, then
6 =
, hence
R =
= 6
