For calculating the mean, you want to add up all of the numbers then divide by how many numbers there are. So you'd do:
5+10+12+4+6+11+13+5 then divide that by 8
The answer to your question is: 8.25
By the Pythagorean theorem,
![a^{2}+12^{2}=13^{2}\\\\a^{2}+144=169\\\\a^{2}=25\\ \\ a=\boxed{5}](https://tex.z-dn.net/?f=a%5E%7B2%7D%2B12%5E%7B2%7D%3D13%5E%7B2%7D%5C%5C%5C%5Ca%5E%7B2%7D%2B144%3D169%5C%5C%5C%5Ca%5E%7B2%7D%3D25%5C%5C%20%5C%5C%20a%3D%5Cboxed%7B5%7D)
Answer:
Step-by-step explanation:
if f(x)=3x-1 and g(x)=2x+5 then
f(x)-g(x)=3x-1-(2x+5)
f(x)-g(x)=3x-1-2x-5
f(x)-g(x)=x-6
Answer:
22 groups of ten
Step-by-step explanation:
121 plus 116 = 237
237 - 9 = 228
lets split 228 into parts
200
20
8
there are 20 groups of ten in 200
2 groups of ten in 20
and 8 has 0 it is a remainder
20 groups plus 2 groups = 22
22 groups of ten
this probobly isn't the easiest way but I don't know how but this is my thought process.
Answer:
So, the answer in short is B) (6,1)
Step-by-step explanation:
If you graph the points, then you see that point A is 8 points away from point B on the X-axis. If you take 8 and divide it by 4, you get 2, so that means that the 1/4 way point is 2 points away from point A, giving you 6 as your x-axis point for this new point. B is the only one with 6 as its spot on the x axis, leaving B as the only choice. BTW you're pretty cute ;)
