Cumulative frequency is the running total of frequencies. It can be shown on a graph by joining points. For example if frequencies are 4, 6, 3, 2, 6, 10 then their cumulative frequencies are 4, 10, 13, 15, 21 and 31 respectively.

Why do car manufacturers give both power curve and torque curve when one is a direct function of the other?

How can you find the retardation of a curve in a speed time graph?
Calculate the gradient of the curve which will give the acceleration. Change the sign of the answer to convert acceleration into retardation.
Why does the rightmost indifference curve give the highest number of utils?
It gives more satisfaction
Give an example of a subset and proper subset?
give example of subset
Why Central Limit Theorem rolling a dice once you will never have a bell shaped curve?
Rolling a die once will give one point. A single point does not even define a line, let alone a curve!
Can you give me an example of a non simple closed curve?
x(t)=t^2 , y(t)=t^3-t is a non-simple curve.
What is a non-example of linear?
It is possible to give an example of non-linear, but I have no idea what a non-example is. Is a non-example of linear a curve. That would be my first thought but not sure
Can a body have constant speed and still be accelerating give example?
Yes. The simplest example is an object moving at a constant speed in a circle.
How do you calculate slope of a curve?
If the curve is on the xy-plane, finding an expression for dy/dx will give you the slope of a curve at a point.
Can you give me a sentence using the word frequency?
What frequency are you on?
What is a 25 degree curve?
A circle is a 360º curve. A 25º curve means that the two radius lines which give the start and end of the curve are 25 degrees apart (even if they are not 'visible' in the curve).
What role does density play in nature?
Density is important in nature as it affects the distribution of living organisms and resources. Higher density can lead to increased competition for resources such as food and space, while lower density can allow for more space and resources for individuals. Density can also impact the functioning and stability of ecosystems, influencing factors like predation, disease transmission, and population dynamics.

What is power curve?
A power curve is an important curve used in aviation. It is the curve of form and induced drag interacting with airspeed. This curve shows pilots that they must give additional thrust as speed decreases to maintain airspeed when airspeed is below a certain point.
What do you understand by the term resonances and give two specific examples of its occurrence?
Resonance refers to the phenomenon where an object vibrating at a certain frequency can cause another object to vibrate at the same frequency. An example of resonance is when a singer hits the right note that shatters a wine glass due to the glass vibrating at the same frequency. Another example is the Tacoma Narrows Bridge collapsing due to wind-induced vibrations matching the bridge's natural frequency.
How do you measure 30MHz frequency at CRO?
If you must use an oscilloscope, then using Lissajous Figures will give you exact multiples of a given frequency. Naturally, you must have a known reference frequency at hand.These days a Frequency Counter will give adequate resolution.
What is parametric cubic curve?
A parametric cubic curve is a cubic curve made up of two equations. For example an x(t) part, and a y(t) part. They may also be known as 'Bezier' curves. Parametric equations are generally controlled by a 't' value. A google search of 'parametric cubic' may also give you some more information.
