,q=0.8, n=400
(a,b)= *=.2+-(2.576*.02)=(.1485, .2515)
We can say with 99% confidence that the proportion of cars costing over $700,000 is in the interval (.1485, .2515).
Hope this helps!
The Pythagoras' theorem and the uniform motion allows to find the answer for the rate of change of distance is
v = 32.3 m / s
The distance is the length of the segment that a white house wing with the helicopter, this can be found using the Pythagoras' theorem
R =
Where R is the distance, x is the horizontal distance where the helicopter flies and y is the vertical distance that corresponds to the flight height
y = 500 m
Since the helicopter flies at constant speed, we can use the uniform motion relation
=
x =
t
Where
is the speed of the helicopter and t is the time
We substitute
r =
Kinematics defines velocity as the change of position in the unit of time
This expression is the change in distance as a function of time for a given speed. In the exercise, this speed is requested for a time of one minute, for the helicopter speed of
v = 2km/min (
) (
) = 33.33 m / s
Let's calculate
v =
v = 32.3 m / s
In conclusion using the Pythagoras' theorem and the uniform motion we can find the answer for the rate of change in distance is
v = 32.3 m / s

Lethargic means "sluggish", kind of inactive
Vital means full of energy, lively
So, they are antonyms
So, for the 2nd part of the analogy, you are looking for a antonym to trite
Trite means lacking originality or freshness. Overused. Kind of like a cliche
So, an antonym could be original, unique, innovative
This is in the wrong category
Answer:
First the time series figures are plotted on a graph. The points are joined by straight lines. We get fluctuating straight lines, through which an average straight line is drawn. This method is however, inaccurate, since different persons may fit different trend lines for the same set of data.24-Mar-2019
