The area of the monitor display in square meters is 0.1158, which is calculated by converting the width and height from inches to meters and then multiplying them.

To calculate the area of the monitor display in square meters, we need to convert the measurements from inches to meters.

First, let's convert the width:

15.51 inches = 0.3937 meters

Next, let's convert the height:

11.63 inches = 0.2946 meters

Now we can calculate the area:

Area = width x height

Area = 0.3937 meters x 0.2946 meters

Area = 0.1158 square meters

Therefore, the area of the monitor display in square meters is 0.1158.

The area of the monitor display can be calculated by multiplying the width and height of the monitor. However, as the given measurements are in inches, we need to convert them to meters to calculate the area in square meters. We converted the width to 0.3937 meters and the height to 0.2946 meters. Then, we calculated the area by multiplying the width and height, which gave us a result of 0.1158 square meters. Therefore, the area of the monitor display in square meters is 0.1158.

The area of the monitor display in square meters is 0.1158, which is calculated by converting the width and height from inches to meters and then multiplying them.

There are 2 feet in real life be 3 inches long in the scale drawing.

The ratio is defined as a relationship between two quantities, it is expressed as one divided by the other.

The stage, which is 56 feet long in real life, is 84 inches long in the scale drawing.

Let the x feet in real life be 3 inches long in the drawing.

According to the given question, we can write a ratio as

56 feet : 84 inches = x feet : 3 inches

⇒ 56 / 84 = x / 3

Apply the cross-multiplication operation,

⇒ 56 × 3 = x × 84

⇒ 168 = 84x

⇒ 84x = 168

⇒ x = 168 / 84

⇒ x = 2

Therefore, there are 2 feet in real life be 3 inches long in the scale drawing.

The small bag is priced at £2.40/kg, while the large bag is priced at £1.83/kg. Therefore, the large bag is the better value, as it offers a lower cost per kilogram compared to the small bag.

To calculate the cost of 1 kg for the small and large bags, we need to determine the cost per gram for each bag and then convert it to the cost per kilogram.

Bag sizes and prices are:

Small bag: 250 g for 60p

Medium bag: 1 kg for £1.80

Large bag: 3 kg for £5.50

To calculate the cost per gram for each bag:

Small bag: 60p / 250 g = 0.24p/g

Large bag: £5.50 / 3000 g = 0.00183 £/g

To convert the cost per gram to cost per kilogram:

Small bag: 0.24p/g * 1000 g/kg = 240p/kg = £2.40/kg (rounded to 2 decimal places)

Large bag: 0.00183 £/g * 1000 g/kg = £1.83/kg

Therefore, the cost of 1 kg for the small bag is £2.40, and the cost of 1 kg for the large bag is £1.83.

The term "mean" refers to the mathematical average of a set of two or more numbers. The arithmetic mean and the geometric mean are two types of means that can be computed. By adding all of the numbers in a set and dividing by the total number of numbers in the set, the arithmetic mean is determined. The standard deviation is a measurement of how widely distributed or how much a group of data differ. A low standard deviation indicates that the values typically tend to be close to the set mean, while a high standard deviation suggests that the values are dispersed over a wider range.

The results of the test will suggest whether the null hypothesis H0: β3 = 0, β4 = 0 is supported or rejected at the 1% significance level.

To test the null hypothesis H0: β3 = 0, β4 = 0 against the alternative H1: H0 is not true at a 1% significance level, you can perform the test by running restricted and unrestricted models.

In the restricted model, you would impose the null hypothesis by setting the coefficients β3 and β4 to 0. Then, estimate the model and obtain the restricted sum of squares (RSS).

In the unrestricted model, you would not impose any restrictions and estimate the model. Obtain the unrestricted sum of squares (USS).

Next, you can calculate the F-statistic using the formula:

F = ((RSS_restricted - RSS_unrestricted) / q) / (RSS_unrestricted / (n - p))

where q is the number of restrictions (in this case, 2), n is the sample size, and p is the number of parameters in the unrestricted model.

Finally, compare the calculated F-statistic to the critical F-value at the 1% significance level (with q and n-p degrees of freedom). If the calculated F-statistic is greater than the critical F-value, you reject the null hypothesis.

The number which best completes the sequence is 31.

To identify the pattern in this sequence, we can observe that it alternates between adding 7 and adding 4. Let's see this step by step:

1. 2 + 7 = 9
2. 9 + 4 = 13
3. 13 + 7 = 20
4. 20 + 4 = 24
5. 24 + 7 = 31

However, there's a discrepancy in the sequence provided: the number 5, which should have been 20, and the number 10, which should have been 24. With the corrected sequence, it should look like this: 2, 9, 20, 13, 24, 19, 17.

Step-by-step explanation:

The vertex form of an equation of the parabola:  

                                                       f(x) = a(x - h)² + k

the vertex is (7, -4)  ⇒   h = 7,  k = -4

so:

     f(x) = a(x - 7)² + (-4)

    f(x) = a(x - 7)² - 4

The parabola goes through the point (5, 8) ⇒   x=5,  f(x)=8

8 = a(5 - 7)²  - 4

8 = a(-2)²  - 4

+4           +4

12  = 4a

a = 3

The forest fires in southern Mexico and Guatemala consumed forest land at a rate of 28,600 acres per week.

During May 1998, forest fires in southern Mexico and Guatemala were burning at a significant rate, resulting in the spread of smoke all the way to Austin. The fires were consuming forest land at a rate of 28,600 acres per week. This indicates the amount of forest area that was destroyed or affected by the fires within a span of one week.

The figure of 28,600 acres per week provides an understanding of the magnitude and impact of the forest fires. It highlights the rapid rate at which the fires were spreading and consuming the forested areas. Forest fires are known to have severe ecological and environmental consequences, including loss of biodiversity, destruction of habitats, and degradation of air quality due to the smoke generated. The fact that the smoke from these fires reached Austin suggests the vast distance covered by the smoke plume, indicating the scale and intensity of the fires.

Forest fires are a significant concern as they pose risks to both human lives and natural ecosystems. They can have long-lasting effects on the affected regions, requiring extensive recovery and rehabilitation efforts. Monitoring and managing forest fires, along with implementing preventive measures, are crucial for minimizing their impact and protecting valuable forest resources.

Hence, the minimum number of at-the-door tickets she needs to sell to make her goal is (B) 334.

Given information: Anna is in charge of the alumni fundraiser for her alma mater. She is selling pre-sale tickets for $10 and at-the-door tickets $25. The venue has the capacity to hold 400 people.

The graph represents the number of tickets Anna needs to sell to offset her upfront costs and raise at least $5,000 for her school.

The minimum number of at-the-door tickets she needs to sell to make her goal can be calculated as follows;

Let's suppose that x represents the number of pre-sale tickets, and y represents the number of at-the-door tickets Anna needs to sell.

Then the following equation represents the total amount of money Anna will earn after selling the given number of tickets;

10x + 25y ≥ 5,000

If she sells all the tickets, she will have sold a total of x + y tickets. But, we know that the venue has a capacity of 400 people.

So, we also know that;

x + y ≤ 400

Solving the two equations for y gives;

10x + 25y ≥ 5,00025y ≥ 5,000 - 10x y ≥ (5,000 - 10x)/25y ≥ 200 - 0.4xy ≤ 333.3 - 0.4x

The least number of tickets each person needs to buy to meet that goal of volleyball team is 3 tickets.

The algebraic expression are used to represent the general problem in the mathematical way to solve them to find the value of unknown variable.

Let suppose the number of tickets sold are n. As the volleyball team is selling raffle tickets for $1.50 each and the total fund raised by selling the ticket is $250.

Thus, the number of tickets sold are,

\(n=\dfrac{250}{1.5}\\n\approx167\)

Now everyone buys the same number of tickets and there are 75 people at the fundraiser. Thus, the number of tickets purchased by each fundraiser is,

\(x=\dfrac{167}{75}\\x=2.23\)

The number of tickets should be more than 2.23 buy by each people to earn the profit at least or more than $250.
