Answer:
1. The speed of the truck, S = D/T.
2. The formula that connects D and T is: S = D/T.
3. The coefficient of variation, k, is the ratio of the standard deviation to the mean speed.
Step-by-step explanation:
a) The speed of a truck at a fixed speed is given as the distance covered by the truck divided by the time it takes the truck to cover the said distance. This implies that speed is a function of distance and time. However, this formula represents the mean speed. There are variations in speed.
b) If the truck covers a distance of 60 kilometers, for example, under 3 hours, we can conclude that the speed is 20 kilometers per hour (60/3) or 20 km/hr.
Answer:
392.5 terms of pi = 125π
Step-by-step explanation:
V = πr²h
V = 3.14 x 5² x 5
V = 3.14 x 25 x 5
V = 3.14 x 125
V = 392.5
If its terms of pi it should be 125π
1,068 is your answer. There will be 356 in each shipment because 1,424 divided by 4 is 356. And 356 times 3 is 1,068.

Answer:
Step-by-step explanation:
perpendicular (p)= 7.7
hypotenuse (h)= 9.7
now
sin x = p / h
sin x = 7.7/9.7
x = sin ^-1( 7.7/9.7)
x = 53°
