Thus, point D's coordinates are (0, 2/3).

The triangle is a polygon with three vertices and three sides. The angles of a triangle are formed by the connection of the three sides end to end at a point. The sum of the three angles of the triangle is 180 degrees.

Knowing that D is a point just on y-axis and that its x-coordinate is zero will help us determine its value. Hence, point D's coordinates are (0, y).

We must first determine the coordinates for point B in order to determine the centre point gravity G of the triangle ABD. B's x- and y-coordinates are 4 and -3, respectively. The line segment AB's midpoint is at:

\(((0+4)/2, (1-3)/2) = (2, -1)\)

Hence, the y-axis and the coordinates (2, -1) are on the line segment BG. Let point G's coordinates be (x, y). G being the triangle ABD's gravitational center, we have:

\(x = (0 + 4 + 0)/3 = 4/3\)

\(y = (1 + y - 3)/3\)

By finding y, we obtain:

\(y = 1/3\)

Thus, point G's coordinates are \((4/3, 1/3)\) .

Knowing that D is on the y-axis and also that G seems to be the midpoint of the line segment AB will help us determine the value of D. A being on the y-axis results in:

DG = GA

\(y - 1/3 = 1/3\)

\(y = 2/3\)

Point D's location is therefore \((0, 2/3)\) .

Answer:

6meters

Step-by-step explanation:

Answer:

120 metres

Step-by-step explanation:

The question says to find the distance between 20 and 80 seconds, so just take the area of the graph between 20 and 80 seconds.

This would result in a shape of a rectangle. [refer to the image attached]

In order to find the distance travelled in that particular time, just find the area of the rectangle.

But here, instead of the length and width being distances in metres, the length would be the velocity and the width would be the time [as per the axis of the graph]. So,

Length = 60 [seconds]

Width = 2 [m/s]

The formula for finding the area of a rectangle is:

Area of a rectangle = length × width

Area of the rectangle = 60 × 2

Area of the rectangle = 120

∴ distance travelled between 20 and 80 seconds is 120m.

The t-value is often used instead of the z-value in statistical tests because the assumptions of the z-value are violated when the sample size is 30 or less.

The t-value is preferred over the z-value in certain scenarios due to the violation of assumptions associated with the z-value when the sample size is small (30 or less). The z-value assumes that the population standard deviation is known, which is often not the case in practice. In situations where the population standard deviation is unknown, the t-value is used because it relies on the sample standard deviation instead. By using the t-value, we account for the uncertainty associated with estimating the population standard deviation from the sample.

Additionally, the t-value is easier to calculate and interpret compared to the z-value. The t-distribution has a wider range of degrees of freedom, allowing for more flexibility in analyzing data. Moreover, the t-value is more widely known among statisticians and is readily available in statistical software packages, making it a convenient choice for conducting hypothesis tests and confidence intervals.

Overall, the t-value is preferred over the z-value when the assumptions of the z-value are violated or when the population standard deviation is unknown.

The number of bacteria y in the culture after x hours will be y = 50(2)ˣ.

An exponential function faster and faster after every next value of the independent variable.

According to the given question the number of bacteria in a culture is increasing according to the law of exponential growth. after 3 hours, there are 400 bacteria, and after 6 hours, there are 3,200 bacteria.

We use the exponential growth equation y = arˣ where a is the initial value and r is common ratio and x represents time.

so 400=ar^3...(i)  and 3200= ar^6...(i)

Dividing equation (ii) by equation (i) and solve for r we get r³ so r =2

substitute r into first equation 400=a(2)³

8a = 400.

a = 50.

∴ The no. of bacteria at any given time x will be.        ( t is replaced by x)

                           (d) 48 m

                           (e) 1818 cm

What is Perimeter?

In geometry, the perimeter is the total length of the boundary or the outer edge of a two-dimensional shape, such as a polygon. It is the addition of the lengths of all sides of the shape. The perimeter is measured in units of length, such as meters or feet.

(a) Rectangle with sides of 10 ft and 11 ft:

Perimeter = 2(10 ft) + 2(11 ft) = 20 ft + 22 ft = 42 ft

(b) Rectangle with sides of 11 ft and 10 ft:

Perimeter = 2(11 ft) + 2(10 ft) = 22 ft + 20 ft = 42 ft

(c) Rectangle with sides of 2.9 m and 4.12 m:

Perimeter = 2(2.9 m) + 2(4.12 m) = 5.8 m + 8.24 m = 14.04 m

(d) Square with sides of 12 m:

Perimeter = 4(12 m) = 48 m

(e) Rectangle with sides of 9 cm and 9 m:

Since the sides are in different units, we need to convert one of them to the other unit. Let's convert 9 m to cm:

9 m = 900 cm

Perimeter = 2(9 cm) + 2(900 cm) = 18 cm + 1800 cm = 1818 cm

Answer:

Step-by-step explanation:

as x increases y increases

Answer:

  D. If the device eliminated all laptop thefts, it would reduce the odds of laptop theft by 100%, so the 300% figure is misleading.

Step-by-step explanation:

You want to know why the statement that "This device reduces your odds of laptop theft by 300 percent" is wrong.

A percentage is a ratio, a pure number with no units. 100% represents 1 of something. When you are talking about percentages, you always need to be clear about what that "something" is.

If that "something" is "the number of laptop thefts," then the number of laptop thefts can only be reduced to zero, a reduction of 100% of its original value.

Here, the problem statement tells you that "something" is "your odds of laptop theft".

The odds of something happening is the ratio of the probability that it will happen to the probability that it won't. Odds can take on any positive value. Because odds are a ratio of pure numbers (probabilities), they also have no units.

If we assume that the odds of laptop theft are more than 3:1 = 3, then it is possible to reduce them by 3 = 300%. That is, the statement in the ad can make sense because of the way it is written. (If the odds of laptop theft are 3 or greater, that means the probability that your laptop will be stolen is greater than 3/(3+1) = 75%.)

If your odds of theft are 7:1 (probability 87.5%), then reducing them by 3 = 300% to 4:1 (probability 80%) is entirely plausible. In this case, the base for the percentage is not the number of thefts, not the original odds, but is the pure number 1.

What is misleading about the statement is that the usual assumptions about the base of the percentage are all incorrect.

(The answer choices assume the base of the percentage is either thefts or the original odds.)

If thefts are cut to 1/3 of their original value, they are reduced (divided) by a factor of 3. As we have seen, "300%" is another way to say "3". Hence a cut to 1/3 of the original value can also be described as "reduced by 300%". Again, the usual assumptions about the meaning of the percentage are incorrect if this is the interpretation to be applied to the ad.

__

Additional comment

Often, ad writers want to state the benefit of their product in the most glowing possible terms. Using percentages without specifying what they refer to offers a lot of opportunities to make the numbers convey the impression of significant benefits.

To be clear, we usually assume that any reference to a percentage is a reference to a fraction of the subject of discussion. As such, any reduction can never be more than 100%. Increases can be as large as you like.

If the original value is zero, a percentage change has no meaning. (You cannot talk about a percentage increase from 0.) If the original value is negative, you need to be very careful to define what you're talking about.

A reduction of 300% is mathematically impossible and the statement in the ad is misleading.

To see why a reduction of 300% is not possible, let's consider an example. Suppose there are initially 10 laptop thefts per month. A 100% reduction would mean that there are zero thefts, so the odds of theft have been reduced by 100%.

To calculate a 300% reduction, we would have to take 300% of the initial number of thefts and subtract it from the initial number of thefts.

300% of 10 = (300/100) x 10 = 30

Initial number of thefts - 30 = -20

The result is a negative number, which does not make sense. It is not possible to have negative thefts.

The correct combination of boxes in the diagram is: Resources, Market Position, and Debt. These three elements are central to the RA theory and are interconnected in their influence on a firm's competitive advantage and performance.

In presenting Resource-Advantage (RA) theory, Hunt and Lambe (2000) use a boxes-and-arrows diagram called "A Schematic of RA Theory of Competition." This diagram illustrates the key elements of the theory and their relationships. The boxes in the diagram represent important components or factors, while the arrows indicate the directional relationships between these components.

Resources refer to the tangible and intangible assets that a firm possesses, including physical, financial, human, and intellectual resources. These resources provide the foundation for a firm's competitive advantage and can include factors such as technology, brand reputation, skilled workforce, and financial capital.

Market Position represents a firm's strategic positioning within its target market. It encompasses factors such as customer perceptions, market share, competitive differentiation, and market reputation. A strong market position enables a firm to leverage its resources effectively and gain a competitive edge.

Debt refers to the financial obligations or liabilities that a firm has, including loans, bonds, and other forms of debt financing. Debt can impact a firm's financial performance and stability, as well as its ability to invest in resources and maintain its market position.

By considering the interplay between resources, market position, and debt, the RA theory emphasizes how firms can leverage their resource advantages to strengthen their market position and achieve better financial performance. This framework highlights the importance of aligning these elements strategically and efficiently managing resources and debt to gain a sustainable competitive advantage in the marketplace.

The total area of the walls is 140 m²

Since the room is in the shape of a cuboid, and we require the area of the walls of the room, the walls of the cuboid are the walls of the room.

So, the total surface area of a cuboid is A = 2(lb + lh + bh) where

Since we require the total area of the walls, lb which is the area of the floor is removed from the equation.

So, the area of the walls is A' = 2(lh + bh)

= 2h(l + b)

Since the dimensions of the floor are 4 meters by 6 meters and the height of the basement is 7 m. So,

So, substituting the values of the variables into the equation, we have

A' = 2h(l + b)

A' = 2 × 7 m × (4 m + 6 m)

A' = 14 m × 10 m

A' = 140 m²

So, the total area of the walls is 140 m²

The relationship between a and p is that they are reciprocals of each other, meaning a = 1/p.

We are given two equations representing the same parabola: x² = 4py and y = ax². We need to find the relationship between a and p.

First, let's solve the second equation for x²:

y = ax²

x² = y/a

Now, we can substitute this value of x² into the first equation:

x² = 4py

y/a = 4py

Canceling out the y terms on both sides:

1/a = 4p

To isolate a, we take the reciprocal of both sides:

a = 1/(4p)

Therefore, we have found that a is equal to 1 divided by 4p.

The relationship between a and p is that a is equal to the reciprocal of p, or a = 1/p. This means that if we know the value of p, we can find the corresponding value of a by taking its reciprocal. Similarly, if we know the value of a, we can find the corresponding value of p by taking the reciprocal of a. These two parameters are inversely related to each other in the context of the given parabola equation.

The probability of getting exactly two face cards in a five-card hand is approximately 0.2638, or about 26.38%.

To find the probability of getting exactly two face cards in a five-card hand, we need to count the number of ways we can get such a hand and divide by the total number of possible hands.

First, let's count the number of ways we can get exactly two face cards in a five-card hand. There are 12 face cards in a standard deck (4 jacks, 4 queens, and 4 kings), so we need to choose 2 of them. There are\({12 \choose 2}\) ways to do this.

Once we have chosen the 2 face cards, we need to choose 3 non-face cards from the remaining 40 cards (52 cards in total minus the 12 face cards). There are \({40 \choose 3}\) ways to do this.

Therefore, the total number of ways to get exactly two face cards in a five-card hand is\({12 \choose 2} \times {40 \choose 3}.\)

The total number of possible five-card hands is\({52 \choose 5}.\)

Therefore, the probability of getting exactly two face cards in a five-card hand is:

\(\frac{\frac{12}{2}\times \frac{40}{3} }{\frac{52}{5} } = 0.2638\)

So the probability of getting exactly two face cards in a five-card hand is approximately 0.2638, or about 26.38%.
