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.
I can help you understand this, however there is nothing but 'M'
I would say it would be 55 and if this question.If you get the answer incorrect my apologies
Step-by-step explanation:
40 + y + y + 30 = 180
2y + 70 = 180
2y + 70 (-70) = 180 (-70)
2y = 180 - 70
2y = 1102y/2 = 110/2
y = 110/2
y = 55
