Step-by-step explanation:
It is given that,
Initial speed of the stone, u = 170 ft/s
It is thrown down from a height of 1020 feet.
We need to its height after t seconds. It can be calculated using second equation of kinematics as follows :
h₀ is initial height, u = -170 ft/s as the stone is throwing down and g = -32ft/s²
Putting values, we get :
Answer:
3672
Step-by-step explanation:
If 8 gallons of gas were used to drive 204 miles multiply 18x204=3,672 miles
We have been given a graph of a normal distributed data and we are asked to find the mean from our graph.
Since we know that a normal distribution is a bell shaped curve, perfectly symmetric around its center. The density curve is symmetric about mean. In a normal distribution mean, median and mode are equal.
We can see from our graph that our graph is symmetric about 4. The center of graph is 4, therefore, mean of our data is 4.
