Answer:
x+2
Step-by-step explanation:
The firs 3 observations are x, x+2, x+4
Mean = sum of data/samaple size
Mean = x+x+2+x+4/3
MEan = 3x+6/3
Mean = 3(x+2)/3
Mean = x+2
Hence the required mean is x+2
Answer:
"Man seeks peace, yet at the same time yearning for war... Those are the two realms belonging solely to man. Thinking of peace whilst spilling blood is something that only humans could do. They're two sides of the same coin... to protect something... another must be sacrificed."
Step-by-step explanation:
Answer:
1. 30
2. 13 meters
Step-by-step explanation:
Let the number be x.
x - (10% of x) = 27.
x - 0.1x = 27
0.9x = 27.
x = 27/0.9
x = 30
The number is 30
Second question:
Length = 2x - 3
Width = x
Perimeter = 72
Perimeter = 2(l + w)
= 2(2x - 3 + x) = 72
4x - 6 + 2x = 72
6x = 72 + 6
6x = 78
w = 78/6 = 13
The width is 13 meters
This quadratic expression can use "sum times", so we can factor it out like this:
