Add 145, 156, 210. and 255 then divide by 4. The mean equals 184.
Answer: Solution
Step-by-step explanation: I believe the answer is solution
S = length of small side
M = length of medium side
L = length of long side
The triangle is scalene meaning that the three sides (S, M, L) are all different. If any two sides were equal, then we'd have an isosceles triangle. If all sides were the same, then the triangle would be equilateral.
"The longest side is twice that of the shortest side" tells us that L = 2*S
The longest side is given to be 6.2 cm, so L = 6.2 and we can find S to be...
L = 2*S
6.2 = 2*S
2*S = 6.2
S = 6.2/2
S = 3.1
The longest side is 6.2 leads to the shortest side being 3.1
Add up the three sides and set that sum equal to the perimeter 14.5
(short side) + (medium side) + (long side) = perimeter
S + M + L = 14.5
3.1 + M + 6.2 = 14.5
M + 9.3 = 14.5
It's not clear where your teacher wants you to stop, so this might be a good place. If you wanted, you can isolate M by subtracting 9.3 from both sides
The absolute deviation for this problem is 2.2.
21 + 40? I didn’t really understand what you meant but hopefully this is what you’re looking for, these numbers add up to 61
