Answer: if the blue rectangles are x, then x = 1/2
1/2 + 1/2 = 1
the green shapes each = 1
so you have 1 + 1 + 1 = 3 which is true so
x = 1/2
Step-by-step explanation:
Answer:
x = 40
Step-by-step explanation:
5= 1/5x -3
Add 3 to each side
5+3= 1/5x -3+3
8 = 1/5x
Multiply by 5 to isolate x
5*8 = 1/5x *5
40 =x
Answer:
4.53
Step-by-step explanation:
Given the data :
4, 5, 10, 11, 15
The mean = 9
The standard deviation of a sample :
s = √[Σ(x - mean)²/(n-1)]
s = √[((4-9)² + (5-9)²+(10-9)² + (11-9)² + (15-9)²) / (5-1)]
s = √(25+16+1+4+36)/4
s = √20.5
s = 4.527
s = 4.53
Answer:
You can divide and see if its devided by 3, and if its not in the times table, you will have a decimal
