What is norm?

In mathematics, a norm is a mathematical concept that measures the size, length, or magnitude of a vector or a mathematical object.

To find the solution of the norm approximation problem with the given scalar variable x ∈ ℝ and the norm types (li norm and la norm) for the specified cases, let's analyze each case separately:

li norm:

A. The average ((1 + b)/m) of the entries of b: The solution would be to minimize ||x - 1||. This is because taking the average of the entries of b does not involve x, so the norm is simply measuring the distance between x and 1.

B. The (or a) median of the entries of b: The solution would be to minimize ||x - m||, where m is the median of the entries of b. This is because the median is the value that minimizes the absolute differences, so the norm is measuring the distance between x and the median.

C. The largest magnitude entry of b: The solution would be to minimize ||x - max(b)||, where max(b) is the largest magnitude entry in b. This is because the norm is measuring the distance between x and the largest magnitude entry.

D. The midrange point ((max(b) + min(b))/2): The solution would be to minimize ||x - ((max(b) + min(b))/2)||. This is because the midrange point is the value that splits the range between the maximum and minimum values in half, so the norm is measuring the distance between x and the midrange point.

la norm:

A. The average ((1/m)Σb) of the entries of b: The solution would be to minimize ||x - (1/m)Σb||. This is because the average is the value that minimizes the sum of squared differences, so the norm is measuring the distance between x and the average.

B. The (or a) median of the entries of b: The solution would be to minimize ||x - m||, where m is the median of the entries of b. This is because the median is the value that minimizes the absolute differences, so the norm is measuring the distance between x and the median.

C. The largest magnitude entry of b: The solution would be to minimize ||x - max(|b|)||, where max(|b|) is the largest magnitude entry in b. This is because the norm is measuring the distance between x and the largest magnitude entry.

D. The midrange point ((max(|b|) + min(|b|))/2): The solution would be to minimize ||x - ((max(|b|) + min(|b|))/2)||. This is because the midrange point is the value that splits the range between the maximum and minimum absolute values in half, so the norm is measuring the distance between x and the midrange point.

In summary, the solution for each case depends on the specific norm type and the property of b that is being used (average, median, largest magnitude, midrange point).

The number of teachers who teach at both Albers Elementary School and Bothel Elementary School is 19.

Let's assume the number of teachers who teach at both schools is 'x'. According to the given information, Albers Elementary School has 39 teachers and Bothel Elementary School has 84 teachers. The total number of teachers at both schools combined is 104.

We can set up an equation to solve for 'x'. The sum of the number of teachers at Albers and Bothel should be equal to the total number of teachers: 39 + 84 - x = 104. Simplifying the equation, we get 123 - x = 104. By subtracting 123 from both sides, we find -x = -19. Multiplying both sides by -1 gives us x = 19.

Therefore, the number of teachers who teach at both Albers Elementary School and Bothel Elementary School is 19.

The word which describes event which has happened because of another change or event is : (a) Effect.

An "Effect" refers to the outcome which arises due to specific "cause" or event. It illustrates the result of a particular action, situation, or condition. When there's a cause-and-effect relationship, the cause is what initiates or triggers the sequence of events, leading to a subsequent effect.

For example, if heavy rain (cause) occurs, flooding (effect) might follow. This concept is important in understanding the relationships between events and their outcomes.

By identifying causes and effects, we understand the underlying mechanisms of various phenomena and make predictions about how changes in one aspect can influence others.

To get the total area of the figure: 6 x 705 = 1725.9 ft².

What is area?

Area is a measure of the size of a two-dimensional surface, such as a region of land or a space in a building. It is typically measured in square units, such as square feet or square meters. Area can also be calculated for three-dimensional objects, such as a cube or other solid shape. Area is an important concept in mathematics and is used to measure the size of many different shapes.

The correct answer is A) 1725.9 ft². To find the area of the regular figure, calculate the area of one of the triangles, and then multiply this by 6 (the number of triangles in the figure). The area of a triangle is A = ½bh, where b is the base and h is the height. The base of the triangle is 19 ft and the height is 12.5 ft. Therefore, A = ½(19) (12.5) = 117.5 ft². Multiply this by 6 to get 6 x 117.5 = 705 ft. Finally, multiply this by the number of triangles in the figure, which is 6, to get the total area of the figure: 6 x 705 = 1725.9 ft².

Step-by-step explanation:

Mean is when you add all the number there are and divide by the total of numbers that you added together like this for example.

(1+2+3+4+5 = 15) THEN (15 / 5 = 3) THE MEAN IS 3.

Median is when you group the number from smallest to biggest and keep on crossing out both side of the number till you reach the middle.

(1, 2, 3, 4, 5) YOUR MEDIAN SHOULD BE 3 CAUSE IF YOU CROSS OUT 1,5 THEN 2,4 YOU WILL GET 3.

Mode are the most common number that you will see. You could have no mode or many mode too.

The solution is: the formula for the area, A, of the pen is given by:

2. (30-W)*W.

Here, we have,

In order to find the answer we need the formula for the area of a rectangle, which is:

area=(length)*(width) which is:

A=L*W

Now, because 60 meters of fencing were used, this means that 60 meters is the perimeter of the rectangle, so:

perimeter=(2*length)+(2*width) which is:

60=2L+2W

30=L+W which can be written as:

30-W=L

Using the area's formula we have:

A=L*W which, using the previous expression, can be written as:

A=(30-W)*W

Events A and B are neither mutually exclusive nor independent.

Mutually exclusive events are events that cannot occur at the same time. In this case, event A is rolling a 1 on the first die, and event B is rolling a 1 on the second die. It is possible for both events A and B to occur simultaneously if you roll a 1 on both dice.

Independent events are events where the outcome of one event does not affect the outcome of the other event. In this case, the probability of rolling a 1 on the second die is influenced by whether or not you rolled a 1 on the first die. Therefore, events A and B are dependent and not independent.

Since events A and B can occur simultaneously and their outcomes are dependent, events A and B are neither mutually exclusive nor independent.

To determine which points satisfy the inequality 2x - 3y < 1, we can substitute the coordinates of each point into the inequality and check if the inequality holds true.

Let's consider the given points:

Point A: (1, 0)

2(1) - 3(0) < 1

2 - 0 < 1

2 < 1 (False)

Point B: (-1, -1)

2(-1) - 3(-1) < 1

-2 + 3 < 1

1 < 1 (False)

Point C: (3, -2)

2(3) - 3(-2) < 1

6 + 6 < 1

12 < 1 (False)

None of the given points satisfy the inequality 2x - 3y < 1.

Therefore, none of the points A, B, or C satisfy the inequality.

Answer:

18.75 mg

Step-by-step explanation:

We can model this problem using the exponencial equation:

y = yo * (1 + r)^x

Where y is the final value, yo is the inicial value, r is the rate and x is the amount of time.

In this problem, we want to find y after x = 4 hours (from 9am to 1pm), we have yo = 300 and r = -0.5 (for every hour, half the caffeine leaves the body). So we have that:

y = 300 * (1 - 0.5)^4

y = 300 * 0.5^4

y = 300 * 0.0625

y = 18.75 mg

So the vector form of the quadratic function y = x² - 6x + 7 is: y = (x - 3)² - 2.

To change from standard form to vertex form, we need to complete the square.

First, we group the x-terms together and factor out any common coefficient of x², giving:

y = x² - 6x + 7

y = 1(x² - 6x) + 7

Next, we need to add and subtract a constant inside the parentheses to complete the square. To determine this constant, we take half of the coefficient of x (-6) and square it:

(-6/2)² = 9

So we add and subtract 9 inside the parentheses:

y = 1(x² - 6x + 9 - 9) + 7

Now we can factor the quadratic expression inside the parentheses as a perfect square:

y = 1[(x - 3)² - 9] + 7

Simplifying and rearranging terms, we get:

y = (x - 3)² - 2
