Mean is the average value of the given set of observations. In statistics, we also come across different types of mean such as Arithmetic, Geometric and Harmonic mean. Leant how to find the mean here.
Stationary point of a function is a point where the derivative of a function is equal to zero and can be a minimum, maximum, or a point of inflection
Learn how to find the square root of 1156 by prime factorisation and repeated subtraction method. Visit BYJU’S to learn the square root of 1156 with solved examples and video lessons.
Understanding how to identify local extrema for a function of several variables, combined with the techniques we learned for optimization problems in single variable calculus, will allow us to optimize surfaces to find such things as maximizing profit or calculating the shortest distance between points...
Add up all the numbers in the x column and write the sum down at the bottom of the x column. Do the same for the other three columns. You will now use these sums to find a linear function of the form y = Mx + B, where M and B are constants. ...
Find the ratio of the changes. ΔfΔx=f(6)−f(1)6−1=205=4ΔfΔx=f(6)−f(1)6−1=205=4 Answer The average rate of change inffbetweenx=1x=1andx=6x=6is 4. Example 2 Suppose the monthly profit for a particular company can be described by the function ...

Concave functions are very useful in maximization problems(like profit maximization), because all you have to do to find the solution is to find where the “peak” of the function is. Definition of a Concave Function A concave function can be defined directly in terms ofconvex functions. They...
The quantity it must produce to satisfy the equality above is 5. This quantity must be plugged back into the demand function to find the price for one product. To maximize its profit, the firm must its of the product for $20 per unit. The total profit of this firm is then $25, or:...
Mathematically, the p-value is calculated using integral calculus from the area under the probability distribution curve for all values of statistics that are at least as far from the reference value as the observed value is, relative to the total area under the probability distribution curve. Sta...
