Answer:
2.0
Step-by-step explanation:
Couldn't really understnd what you wrote but I'll assume it's the standard deviation of a fair, 7-sided die
The standard deviation is just the square root of the variance (which is just the second moment minus the first moment squared)
The first moment (AKA the average is..)

The second moment is..


The actual speed of the plane with the wind:
v² = ( 150 + 50 · cos 45°)² + ( 50 · sin 45°)²
v² = ( 150 + 35.355 )² + 35.355²
v² = 34,356.467 + 1,249.976
v = √35,606.452
v = 188.7 mph
The answer to this answer choice is A. (45x12)+75=c
Answer:
subtract 8x from both sides
Step-by-step explanation:
this is the first step
Answer:
1/3
Step-by-step explanation:
There are 6 faces on a number cube.
We know that 2 of those faces are greater than 4.
So,
2 out of 6 faces=2/6=1/3
