Answer:
x = 55
Step-by-step explanation:
x + (2x+15) = 180
3x + 15 = 180
3x = 165
x = 55
Answer:
1536 in^2
Step-by-step explanation:
This is basically asking for the surface area so knowing that is a cube all the sides are equal so one side would be 16(16) which is 256 in ^2. The knowing that there is 6 sides you would multiply it by 6 which is 256(6)= 1536^2
Since the plane starts at (0,0), you don't have to factor in anything except for the translation. The plane would be at (-.5, 3.5)
Answer:
The standard deviation is 10.38
Step-by-step explanation:
Given;
Variance, v = 107.76
mean, x = 34.2
The standard deviation is given by;
standard deviation = √variance
standard deviation = √107.76
standard deviation = 10.381
standard deviation = 10.38 (two decimal places)
Therefore, the standard deviation is 10.38
