Answer: 2.76 g
Step-by-step explanation:
The formula to find the standard deviation:-
The given data values : 560 g, 562 g, 556 g, 558 g, 560 g, 556 g, 559 g, 561 g, 565 g, 563 g.
Then, 
Now, 
Then, 
Hence, the standard deviation of his measurements = 2.76 g
5/6......5 out of 6.......using division, it is 5 divided by 6 = 0.833

Answer:
3.019 hours.
Step-by-step explanation:
In this case they ask us to calculate the time in hours that are in those distances, for this we have the speed and the distance, we know that speed is equal to:
v = d / t
therefore the time would be:
t = d / t
we must pass the distance that is in kilometers to miles, like this:
350 km * 1 mile / 1.61 km = 217.4 mi
Now if replacing:
t = 217.4 / 72 = 3.019
Therefore, the time would be 3.019 hours.
Answer:
Step-by-step explanation:
Any linear equation can be written as y = mx + b
The point will determine b
The slope (m) is found by this formula for a perpendicular line
m1 * m2 = - 1
m1 = -1/m2
m1 = -1/(-2/3)
m1 = 3/2
So our equation looks like
y = 3/2 x + b
Now we use the point (4,-8)
-8 = 3/2 (4) + b
-8 = 3(2) + b
-8 = 6 + b
b = - 14
The answer is
y = 4/2 - 14
