The set S is linearly dependent and the matrix A has rank 3.

Sets are groups of well-defined objects or components in mathematics. A set is denoted by a capital letter, and the cardinal number of a set is enclosed in a curly bracket to indicate how many members there are in a finite set.

Set A, for instance, is a collection of all the natural numbers, with the form A = 1, 2, 3, 5, 6, 7, 8, etc.

The maximum number of linearly independent columns (or rows ) of a matrix is called the rank of a matrix. The rank of a matrix cannot exceed the number of its rows or columns.

Thus, The set S is linearly dependent and the matrix A has rank 3.

Since n•u is not equal to 0, we conclude that the vector u is not in the plane spanned by the columns of A.

A vector u is in the plane spanned by the columns of a matrix A if and only if the dot product between u and the normal vector of the plane is equal to 0.

In this case, let A = [5 -2 1; -3 6 1]. To determine if u = [-12, 36, 8] is in the plane spanned by the columns of A, we can calculate the dot product between u and the normal vector of the plane, which can be found by taking the cross product of the two columns of A.

Since the cross product of two columns in A gives the normal vector of the plane spanned by the columns, we have:

n = (5, -2, 1) × (-3, 6, 1) = (18, -26, -11)

Next, we calculate the dot product of n and u:

n•u = (18, -26, -11) • [-12, 36, 8] = 18 * -12 - 26 * 36 - 11 * 8 = -816 - 936 - 88 = -1840

Since n•u is not equal to 0, we conclude that the vector u is not in the plane spanned by the columns of A. In other words, u is not orthogonal to the normal vector of the plane and therefore, is not in the plane.

The limit of (xy⁴)/(x⁴y⁴) is 0.

The limit squeeze theorem (also known as sandwich theorem) states that if a function f(x) lies between two functions g(x) and h(x) and the limits of each of g(x) and h(x) at a particular point are equal (to L), then the limit of f(x) at that point is also equal to L. This looks something like what we know already in algebra. If a ≤ b ≤ c and a = c then b is also equal to c. The squeeze theorem says that this rule applies to limits as well. We define the squeeze theorem mathematically as follows:

"Let f(x), g(x), and h(x) are three functions that are defined over an interval I such that g(x) ≤ f(x) ≤ h(x) and suppose lim ₓ → ₐ g(x) = lim ₓ → ₐ h(x) = L, then lim ₓ → ₐ f(x) = L".

Here:

The function f lies between g and h and hence they are lower and upper bounds of f respectively.

'a' doesn't necessarily need to be within I.

We have to find the limit of (xy⁴)/(x⁴y⁴).

After applying the limit squeeze theorem, we get

[tex]\lim_{x \to \infty} \frac{xy^{4} }{x^{4}y^{4} }\\ = \lim_{x \to \infty} \frac{1}{x^{3} } \\= 0[/tex]

Thus, the limit of (xy⁴)/(x⁴y⁴) is 0.

Adding parentheses to a regular expression can be used to capture specific information, such as the street number and apartment number in this example.

A regular expression is a pattern used to match and search for specific strings. To remember the street number "613" and apartment number "apt 57" but not the street name, we can add parentheses to the regular expression to create capturing groups. The parentheses will capture the desired information and allow us to reference it later if needed.

The regular expression would look something like this: (613) (apt 57)

The parentheses indicate that the information inside should be captured as a group. This regular expression will match a string that contains the street number "613" and the apartment number "apt 57", and capture these values in two separate groups.

For example, if we have the following address: "613 Main St, apt 57"

We can use the regular expression to match the desired information:

(613) (apt 57)

In this case, the two groups captured are "613" and "apt 57". The information inside the parentheses can be accessed and used for various purposes, such as formatting or validation.

In summary, adding parentheses to a regular expression can be used to capture specific information, such as the street number and apartment number in this example. This allows for more precise and flexible matching and extraction of information from strings.

Therefore, Adding parentheses to a regular expression can be used to capture specific information, such as the street number and apartment number in this example.

By applying the debt concept, it can be concluded that:

A. He should pay $466.02 to pay off the balance on the account.

B. The balance on his account is $190.68

Debt is an obligation that requires one party, the debtor, to pay money or other agreed-upon value to another party, the creditor.

We have the following information:

Ahmad owes $382.45, and because he owes, it means this value is the debt, and we write it:

D = $382.45

Then he returns two items ($25. 10 & $34. 50) so that their values get credited into his accounts.

D = $382.45 - $25.10 - $34.50 = $322.85

Now after this, he makes another two purchases of $45 and $98.17, which increase his debt and makes:

D = $322.85 + $45 + $98.17 = $466.02

Part A: Since the debt or the account balance is $466.02, then he should pay $466.02 to pay off the balance on the account.

Part B: However, instead of paying off the balance, Ahmed makes a payment of $300 and he has to be charged $24.66. It means that his debt is not paid off:

D = $466.02 - $300 + $24.66 = $190.68

So, the balance on his account is $190.68.

The average speed of the whole journey is 24 kilometres per hour.

The average speed is the total distance travelled by the object in a particular time interval.

A car travels from X to Y at an average speed of 60km/h and returns to X at a speed of 40km/h.

Therefore, the average speed for the whole journey can be calculated as follows:

The total distance travelled is 120 km.

Hence,

total time = 120 / 60 + 120 / 40

total time = 2 + 3 = 5 hours

Therefore,

average speed = total distance / total time taken

average speed = 120 / 5

30 students are taking none of the classes.

We can use the Principle of Inclusion-Exclusion (PIE) to determine the number of students taking none of the classes. The PIE states that the total number of elements in the union of several sets is equal to the sum of elements in each set, minus the sum of elements in the pairwise intersections, plus the sum of elements in the three-way intersections, and so on.

In this case, we want to find the number of students taking none of the classes, which is equal to the total number of students (100) minus the number of students taking at least one class.

So, we can apply PIE as follows:

students taking none of the classes = 100 - (students in prob. + students in la + students in comp - students in prob. & comp - students in la & comp - students in prob. & la + students in prob., comp & la)

Using the given information, we have:

students taking none of the classes = 100 - (65 + 45 + 40 - 25 - 20 - 30 + 10)

students taking none of the classes = 100 - (95 - 25)

students taking none of the classes = 100 - 70

students taking none of the classes = 30

Hence, 30 students are taking none of the classes.

x' = -8*cos270 - 10 * sin270

x' = 0 + 10

x' = 10

y' = -8*cos270 +  10* sin270

y' = 0 -10

y' = -10

(x' , y' ) = (10,-10)

similarly,

for q (-4,2)

x' = -4*cos270 - 2 * sin270

x' = 0 + 2

x' = 2

y' = -4*cos270 + 2 * sin270

y' = 0 -2

The y-intercept of the line y = 2x - 4 is the point (0, -4), which means that the line crosses the y-axis at a point with a y-coordinate of -4.

What is the slope intercept?

The slope indicates the steepness of a line and the intercept indicates the location where it intersects an axis. The slope and the intercept define the linear relationship between two variables and can be used to estimate an average rate of change.

The equation y = 2x - 4 represents a straight line in a coordinate plane.

In this equation, y is the dependent variable and x is the independent variable.

The slope of the line is 2, meaning that the line rises 2 units vertically for every 1 unit it moves horizontally to the right.

The y-intercept is the point where the line crosses the y-axis, and can be found by setting x equal to zero and solving for y.

In this case, when x = 0, y = 2 * 0 - 4 = -4.

Hence, the y-intercept of the line y = 2x - 4 is the point (0, -4), which means that the line crosses the y-axis at a point with a y-coordinate of -4.

The correct answer fort parallel angles is x = 33° and y = 10°.

The angles created when a transversal intersects two parallel lines are known as corresponding angles. Opening and shutting a lunchbox, completing a Rubik's cube, and an infinite stretch of parallel train lines are common examples of identical angles.

Angle 3y + 20° and angle 5y are parallel angles.

3y + 20° = 5y

2y =  20°

y = 10°

Angles 2x - 16° and 3y + 20° are in direct opposition to one another.

3y + 20° =  2x - 16°

Put the value of angle y in the equation.

3(10) + 20 = 2x - 16

30 + 20 = 2x - 16

50 = 2x - 16

2x = 66

After the second man is chosen, there are only 2 possible choices for the third man.

Next, we have to choose 3 women from 8. There are C(8,3) = 56 ways to do this.

So, the total number of different committees possible is 6 * 3 * 2 * 56 = 3456.

Answer:

50%

Step-by-step explanation:

7 nurses

3 doctors

4 offices

14 in total

7/14 or 50% is the probability

Answer:

0.50

Step-by-step explanation:

[tex]7 + 3 + 4 = 14[/tex]

So, the probability that the nurses are selected to attend the conference is,

[tex] \frac{7}{14} = \frac{1}{2} [/tex]

[tex] \frac{1}{2} = 0.50[/tex]

The system of equations is given by: y = -2/5x +2 and y = -3x - 4.

Choose two equation pairs at random from the system. Apply the Addition/Subtraction technique to each pair to remove the same variable. Use the Addition/Subtraction method to solve the two new equations as a system. Reintroduce the solution into one of the original equations and find the third variable there.

equations  is:-

y = -2/5x +2 and y = -3x - 4.

when x=0

y= -2/5(0) +2 = 2

y  = -3(0) - 4= 4

when y=0

0= -2/5x +2

x=.80

0= -3x - 4

x=13.33

so from the above value we come to conclusion that system of equations is given by: y = -2/5x +2 and y = -3x - 4.
