How do you determine if an interval is continuous?
A 1-dimensional interval (a, b) is continuous if for any k in (0, 1) the point a + k*(b-a) = a*(1-k) + k*b is also in the interval. This is equivalent to the statement that every point on the line joining a and b is in the interval. The above can be extended to more dimensions analogously.
How many hours is 12 o clock?
You have given just a starting point or an ending point. You have to give two values in order to calculate the interval. You must also be clear if you are using a 24 hour clock or a 12 hour clock.
Is absolute zero point measured by interval or ratio scale?
Ratio
The set of points in space that are a given distance from a given point is?
A spherical surface, with its center at the given point, and its radius equal to the given distance.
What equals to the constant velocity needed to cover the given displacement in a given time interval?
The required velocity is the given displacement/the given time intervalin the direction from the starting point to the end point.

The number of waves passing through a given point during the interval of one second?
That's called the frequency.
What is the sum of the product of the frequencies and the square of the class marks (ΣfX²60,55,40,48,52,36,50?
Step 1: Find the midpoint of each interval. Step 2: Multiply the frequency of each interval by its mid-point. Step 3: Get the sum of all the frequencies (f) and the sum of all the fx. Divide 'sum of fx' by 'sum of f ' to get the mean. Determine the class boundaries by subtracting 0.5 from the lower class limit and by adding 0.5 to the upper class limit. Draw a tally mark next to each class for each value that is contained within that class. Count the tally marks to determine the frequency of each class. What is this? The class interval is the difference between the upper class limit and the lower class limit. For example, the size of the class interval for the first class is 30 – 21 = 9. Similarly, the size of the class interval for the second class is 40 – 31 = 9.
Why interval estimates are preferred over point estimates?
Interval estimates are generally to be preferred over point estimate
What is Confidence Intervals of Interval Estimate?
An open interval centered about the point estimate, .

What is the hello interval?
The 'hello interval' is the time between hello packets, set in seconds as a parameter between two numbers, in OSPF routing timer protocols. The hello interval is the contacting-hello exchange between point A and Point B in computing, where a message is sent via an interface to a website or other computer point and returned to the user. Read about configuring routing timers for 'hello interval' and 'dead interval'.
What is the difference between a line and an interval?
A line is never ending while a interval has a fixed end and start point.
How do you determine if an interval is continuous?
A 1-dimensional interval (a, b) is continuous if for any k in (0, 1) the point a + k*(b-a) = a*(1-k) + k*b is also in the interval. This is equivalent to the statement that every point on the line joining a and b is in the interval. The above can be extended to more dimensions analogously.
Can equality or inequality define the interval on a number scale?
An equality defines a specific point (or points). An inequality can define an interval.
What does it mean when f is differentiable at x equals 2?
what does it mean when f(x) is differentiable along an interval?it means that f is continuous along that domain. In other words, the curve f is smooth and does not break at any point along the interval.what does it mean when f(x) is differentiable at a point c?It means that f is continuous above the domain given by the interval that is an infinitesimally small distance from c. In other words the curve, f(x), is smooth and does not break along the differentially small interval given by c and at all of the values unimaginably close to c.what does it mean when the derivative of f(x) at c equals 2?It means that the instantaneous rate of change (slope) of f(x) at that point is equal to 2.what does it mean when the derivative of f(x) everywhere along an interval equals 2?It means that every single point along that interval has the same slope of 2. In other words, that interval yields a line with a slope of 2.
