Well, the first dot is the known as the Minimum. Then, the second dot is the 1st Quartile. The dot in the middle of the box with the line through it is the median (2nd Quartile). Then the last dot forming the box is the 3rd Quartile. And the final dot is the 4th Quartile (Also known as the Maximum). In this case, it is asking about the Median...which would be 15.5. Hope this helped!
Answer:
If it says (10a + 4): 40a + 16
If it says (10a - 4): 40a - 16
Step-by-step explanation:
If it's an equilateral quadrilateral, that means all sides are equal. So you would multiply the given side by the number of sides. Then simplify you equation.
I can't read it if it says (10a + 4) or (10a - 4) so i'll just do both and you can use which one it says.
If it says (10a + 4):
4(10a + 4)
40a + 16
If it says (10a - 4)
4(10a - 4)
40a - 16
Answer:
59°
Step-by-step explanation:
γ=cos^-1(18^2+22^2-20^2)/2*18*22)=58.99242°
It's pretty simple! So it looks like you are learning proportions. You would cross multiply to achieve your answer.
First, let's do your first problem:
2 12
--- = ----
5 n
You would take 5 and multiply it by 12 and get 60! Then you would do the same with 2 times n, giving you 2n (because you do not know what n represents YET.)
Now you should have this:
60=2n OR 2n=60
We must isolate our variable, in order to do that, get rid of two! But how? You would do this by dividing 2n by 2. Yet in equations, when you do something to one side, you must do it to the other because they must be EQUAL! (hence the "equa-" in equation)
2n=60
--- ---
2 2 DIVIDE 2 into 60
----------
n= 30 Simplify!
Your final answer for the first question is n= 30!
