Find 2x^3-x^3+4x+7 divided by x+3

The gradient of the vector field of function f(x, y, z) is (12x,2y,2z)

The term gradient of the vector in math is calculated as the vector whose components are given by the partial derivatives of the function and it can be evaluated at any given point, and the gradient represents the direction and magnitude of greatest increase of the function at that point.

Here we have given the function f(x, y, z) = 6x² + y² + z²

Now we have to calculate the gradient of the function by using the following step.

In the given question, we have identified the values of the following as,

=> x = 6x²

=> y = y²

=> z = z²

Now, in order to find the gradient of a function (which is a vector), differentiate the function with respect to each variable.

=> ∇f=(∂f/∂x, ∂f/∂y, ∂f/∂z)

Now, the value of

=> ∂f/∂x = 12x

=> ∂f/∂y = 2y

=> ∂f/∂z = 2z

Now, we have to plug in the point:

=> ∇f(x, y, z) = (12x,2y,2z)

The probability that the student competed in Rhythm given they had competed in Smooth or Standard: P(Rhythm |Smooth or Standard) or P ( A/( B or C)) is 0.6613 = 66.13%.

We have, A survey was conducted at a local ballroom dance studio asking students with three dance categories. The above Venn diagram shows the number of students in these three categories of dance.

Total number of students in all dance categories n(A or B or C) = 5 + 6 + 8 + 12 + 14 + 15 + 10 + 4

= 74

let us consider the events

A : students in Rhythm dance category

B : students in Standard dance category

C : students in Smooth dance category

Using the conditional probability,

Probability that student has competed in Rhythm and they have competed in Smooth, P(Rhythm/ smooth) = P(A/C) = P(A and C)/P(C)

= (12+14)/74 = 26/74 = 0.703

but we have to calculate probability that the student competed in Rhythm given they had competed in Smooth or Standard, P(Rhythm/Smooth or Standard) = P(Rhythm and (Smooth or Standard))/P(Smooth or Standard)

i.e., P( A/(B or C) )= P(A and (B or C))/P(B or C)

n(B or C) = n(B) + n(C) - n( B and C)

=> n(B or C) = 14 + 5 + 10 + 15 + 12 + 14 + 5 + 6 - 5 - 14 = 62

Now, P(B or C) =n(B or C)/n(A or B or C)

=> P(B or C) = 62/74 = 0.703 = 70.3%

P(A and (B or C)) = n(A and (B or C))/n(A or B or C)

n(A and (B or C)) = n(A) + n(B or C) - n(A or B or C)

= 12 + 14 + 15 + 8 + 62 - 70 +4 = 41

P(A and (B or C)) = 37/74

So, P( A/(B or C) )= P(A and (B or C))/P(B or C)

=> P( A/(B or C) )= 41/74/62/74 = 41/62

= 0.6613 = 66.13%

Hence, the required probability is 66.13%.

The exact length of the curve of the equation y = 1/4 x² − 1/2 ln(x), 1 ≤ x ≤ 4 is 1.125

Here we have given an equation y = 1/4 x² − 1/2 ln(x) with the limit as 1 ≤ x ≤ 4.

Now, the arc length is calculated by differentiating the terms, then we get,

=> dy/dx = x/2 - 1/2x

Now, we have to apply these derivative on the arc length formula, then we get,

=> length =  [tex]\int\limits^4_1 {\sqrt{1 + (\frac{x}{2} -\frac{1}{2x})^2 } } \, dx[/tex]

When we simplify this one then we get,

=> length = [tex]\frac{1}{2} \int\limits^4_1 {\sqrt{x^2 + 2 + \frac{1}{x^2} } } \, dx[/tex]

When we further simplify this one then we get,

=> length = [tex]\frac{1}{2} \int\limits^4_1 {x + \frac{1}{x} } \, dx[/tex]

Now, the result of the differentiation is

=> length = 1/2 [17/4 - 2]

=> length = 1/2 [9/4]

Our Median will be 37 when the Mode is 15 and the Mean is 48.

Relationship between Mean Median and Mode?

An empirically established link exists between the mean, median, and mode in statistics. The average difference between the mean and the mode is three times greater than the difference between the mean and the median, according to observations of innumerable data sets. The equation for this relationship is:

Mode - Mean = 3*(Mean – Median).

on solving this we get:

Mode = 3 * Median - 2 * Mean

In our question, it is given that the Mode is 15 and the Mean is 48 and we have to calculate the Median.

Putting these values in our formula, we get:

15 = 3 * Median - 2 * 48

3 * Median = 15 + 96

Median = 111/3 = 37.

So, finally, our result will be 37.

By resolving these equations, we can arrive at one solution.

To find the number of solutions to a system of equations, you can solve the system either by graphing the equations or by using algebraic methods such as substitution or elimination.

If the equations are compatible (meaning that there is at least one combination of values for the variables that satisfies both equations), then the system has at least one solution. If the equations are independent (meaning that they are not related to each other and cannot be derived from each other), then the system has exactly two solutions. If the equations are dependent (meaning that one of the equations can be derived from the other), then the system has exactly one solution. If the equations are incompatible (meaning that there is no combination of values for the variables that can satisfy both equations), then the system has no solutions.

In this case, the equations are 3x + 2y = 5 and 2x - 3y = 7. To find the number of solutions to this system, you can either graph the equations or solve the system using algebraic methods.

Using algebraic methods, you can start by solving one of the equations for one of the variables in terms of the other:

3x + 2y = 5

2y = -3x + 5

y = (-3/2)x + (5/2)

Then, you can substitute this expression for y into the other equation to solve for x:

2x - 3((-3/2)x + (5/2)) = 7

2x + (9/2)x - (15/2) = 7

(11/2)x - (15/2) = 7

(11/2)x = (15/2) + 7

(11/2)x = (15 + 14)/2

(11/2)x = 29/2

x = 29/11

Substituting this value for x back into the first equation, you can solve for y:

3(29/11) + 2y = 5

87/11 + 2y = 5

2y = 5 - 87/11

2y = (55 - 87)/11

2y = -32/11

y = -32/22

Therefore, the solution to this system of equations is x = 29/11 and y = -32/22. Since there is only one solution, this system has exactly one solution.

A graph is said to be infinite when it has an infinite number of points that could be connected, or an infinite number of lines, curves, or shapes that could be drawn on the graph.

A graph is a visual representation of data or information, typically plotted on an x-axis and a y-axis. A graph is said to be infinite when it has an infinite number of points that could be connected, or an infinite number of lines, curves, or shapes that could be drawn on the graph. For example, a line graph without an end point is considered infinite because it theoretically continues forever. Similarly, a circle graph with no beginning or end point could also be considered infinite. Other types of graphs that can be considered infinite include bar graphs, area graphs, scatter plots, and pie charts. When determining whether a graph is infinite, it is important to consider the purpose of the graph and its data. If the graph is meant to represent an infinite set of data points, then it can be considered infinite. Likewise, if the graph is meant to represent a function that goes on forever, then it should also be considered infinite. Ultimately, the definition of infinity can vary depending on the situation, so it is important to consider all aspects of the graph before making a judgement.
