The definition of the gradient vector for point a to b is defined below.

Vector:

In math vector value consists of magnitude and direction.

Given,

Here we need to find the gradient vector of point a or point b.

According to the definition of vector, a multidimensional input have partial derivatives, you might wonder what the full derivative of such a function is. Here in the case of scalar-valued multivariable functions, meaning those with a multidimensional input but a one-dimensional output, the answer is the gradient.

Where as the gradient of a function f, denoted as ∇f,

Where f, is the collection of all its partial derivatives into a vector.

Here the point a and b is more horizontal because of the partial derivative nature of vector.

Based on the First image, the correct option is the fourth image while based on the second image, the correct option is the fourth image also.

Given that the pre-image is rotated in the direction of the arrow as seen an the first image.

It is required to find the image formed also in that given direction.

Based on the fact that the arrow is rotating counter-clockwise, we get that, the shape of the pre-image will also rotate upwards towards the left hand side of the image shown.

The result will differ between increase and decrease because the numerator in the formula represents the change (E - B). If the ending number is greater than the beginning number, it will result in a positive value, indicating an increase.

a. Let's use the variable A to represent the area of a room.

b. We can use the variable WA to represent the wall area of a room, including windows and doors.

c. For the wall area of a room not including two windows and a door, let's use the variable WNA.

d. To calculate the number of miles given a number of feet, we can use the variable M to represent the number of miles and F to represent the number of feet. Since there are 5,280 feet in a mile, we can set up the equation as:

M = F / 5280

e. To calculate the percent increase or decrease of a value given the beginning number (B) and the ending number (E), we can use the variable P to represent the percent change. The formula for percent change is:

Answer:

  yes

Step-by-step explanation:

You want a graph of P = 125 +50W.

The given equation is in slope-intercept form. The independent variable is W, and the dependent variable is P.

Usually, the independent variable is graphed on the horizontal axis, which you have done.

The dependent variable is graphed on the vertical axis, which you have done.

The axes are correctly labeled and graduated.

The "y-intercept" (P value) when the independent variable is zero is the constant in the equation, 125. You have correctly shown that on the graph.

The slope of the line is the coefficient of the independent variable (W) in the equation. You have correctly shown that P increases by 50 when W increases by 1.

Yes, you properly graphed the equation.

The first book you select can be any one of 700.

The second book can be any one of the other 699.

The third book can be any one of the remining 698.

The total number of ways to gather three books from the shelves into your hands is  (700 · 699 · 698)  =  341,531,400 ways .

BUT ...

When you bring three books to the check-out counter, Marian the Librarian doesn't know in which order you took them down off the shelves.  You could have gathered the same three books in (3 · 2 · 1) = 6 different ways.

So, even though there are 341,531,400 ways to gather up three books, there are only (341,531,400 / 6) = 56,921,900 different GROUPS of three books that you can choose to take home.

If this experiment was performed many times you would expect that the average number of heads is 5.

It is the chance of an event to occur from a total number of outcomes.

From the graph,

The theoretical probability of getting 5 heads in ten flips of a fair coin.

Step-by-step explanation:

The coefficient of variation (CV) is a measure of relative variability and is calculated by dividing the standard deviation by the mean, and then multiplying by 100 to express it as a percentage.

In this case, the mean weight is 340 grams, and the standard deviation is 5.2 grams.

CV = (Standard Deviation / Mean) * 100

CV = (5.2 / 340) * 100

CV ≈ 1.53%

For an equation to be a function, there should be only one y-coordinate per x-coordinate. Since this relation has both (-1,9) and (-1,4), this is not a function.

Answer:not a function

Step-by-step explanation:

because when you put the points on the coordinate plane your shape will come out as a v shaped object.

Typical examples are functions from integers to integers or from the real numbers to real numbers

The value of  variable x in the equation is 16.

The equation represented as follows:

x + 14 + x³ = 78

The value x is the variable.

A variable is number represented with a letter in an equation.

Therefore,

x + 14 + 3x = 78

subtract 14 from both sides of the equation

x + 3x + 14 - 14 = 78 - 14

x + 3x = 64

Therefore,

4x = 64

divide both sides by 4

A population consists of a complete set group of individuals, whether that group comprises a nation or a group of people with a common characteristic.

Using the perimeter relation, the amount of fencing left is obtained using the subtraction operation. Hence, amount of fencing left is 90 feets

Recall :

Hence,

180 = 2(x + 4x)

180 = 2(5x)

180 = 10x

x = 180 / 10

x = 18 feets

Amount of fencing left :

180 - (18 + 4(18))

180 - (18 + 72)

180 - 90

= 90 feets

Given that;

To find the surface area of this square pyramid

Now, We know that;

the surface area of this square pyramid is,

⇒ SA = B + 1/2 pl

Where, B represents the area of the base. p represents the perimeter of the base. l represents the slant height.

Now, We get;

B = 12 x 8

B = 96

p = 2 (12 + 8)

p = 40

l = 10

Thus, the surface area of this square pyramid is,

⇒ SA = B + 1/2 pl

⇒ SA = 96 + 1/2 x 40 x 10

⇒ SA = 96 + 200

The following parts can be answered by the concept of Standard deviation.

4. To test the scenario, we can set up the following hypotheses:

Null Hypothesis (H0): The proportion of positions where men are paid more than women is equal to 0.5 (equal pay).
Alternative Hypothesis (H1): The proportion of positions where men are paid more than women is greater than 0.5 (men are paid more).

5. To calculate the test statistic and p-value, we'll use a one-sample proportion test. In this case, the sample proportion (p-hat) is 19/21. The hypothesized proportion (p0) is 0.5. The sample size (n) is 21.

Test Statistic (z) = (p-hat - p0) / √((p0 × (1 - p0)) / n)
z = (19/21 - 0.5) / √((0.5 × (1 - 0.5)) / 21)
z ≈ 6.43

To find the p-value, we look at the upper tail of the standard normal distribution corresponding to the z-score of 6.43. Since this z-score is very large, the p-value is extremely small (approaching 0).

6. With such a small p-value (close to 0) and a significance level (α) of 0.05, we reject the null hypothesis in favor of the alternative hypothesis. This sample provides convincing evidence that men are paid more than women in the examined positions at the 0.05 significance level.

In any triangle, the greatest angle is opposite to the greatest side and the smallest angle is opposite to the smallest side.

Knowing that, first let's find the measure of the third angle, using the property that the sum of internal angles in any triangle is equal to 180°:

The smallest angle is C, so the smallest side is DE.

The greatest angle is E, so the greatest side is CD.

Therefore the order is:

DE < CE < CD
