To find the midpoint of a class interval, you add the lower limit and the upper limit of the interval and then divide the sum by 2. For example, if the class interval is 10-20, the midpoint would be (10 + 20) / 2 = 15. This midpoint can then be used in calculations like finding the mean or in statistical analysis involving frequency distributions.

How do you check f(xy) is continuous or not on interval?
To check if the function ( f(xy) ) is continuous on a given interval, you can follow these steps: First, identify the points in the interval where ( xy ) is evaluated. Then, determine if ( f ) itself is continuous at those points by checking if the limit of ( f(xy) ) as ( (x,y) ) approaches any point in the interval equals ( f ) at that point. If both the function and the limit are defined and equal at all points in the interval, then ( f(xy) ) is continuous on that interval.
How is the frequency class midpoint calculated?
The frequency class midpoint is calculated by taking the average of the lower and upper boundaries of a class interval. Specifically, you add the lower boundary to the upper boundary and then divide the sum by two. This midpoint represents the center point of that class and is often used in statistical calculations, such as determining the mean of grouped data. For example, if a class interval is 10-20, the midpoint would be (10 + 20) / 2 = 15.
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.

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.

What is the number of waves length that pass a point a given time interval?
The number of wavelengths that pass a point in a given time interval is determined by the wave's frequency and the speed of the wave. It can be calculated by dividing the speed of the wave by the wavelength. This relationship is represented by the equation: Number of wavelengths = wave speed / (frequency * time).
How do you check f(xy) is continuous or not on interval?
To check if the function ( f(xy) ) is continuous on a given interval, you can follow these steps: First, identify the points in the interval where ( xy ) is evaluated. Then, determine if ( f ) itself is continuous at those points by checking if the limit of ( f(xy) ) as ( (x,y) ) approaches any point in the interval equals ( f ) at that point. If both the function and the limit are defined and equal at all points in the interval, then ( f(xy) ) is continuous on that interval.
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
Can you explain how to find overlapping intervals in a given set of data?
To find overlapping intervals in a set of data, you need to compare the start and end points of each interval. If the end point of one interval is greater than the start point of another interval, then they overlap. Repeat this comparison for all intervals in the data set to identify overlapping intervals.

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'.
