The coordinate of the centroid of the given triangle will be at (-2.33,5).

A triangle is a 3-sided shape that is occasionally referred to as a triangle. There are three sides and three angles in every triangle, some of which may be the same.

The given triangle with vertices has been drawn.

The midpoint of H( – 6, 3) and F(1, 5) will be as,

x = (-6 + 1)/2 = -2.5

y = (3 + 5)/2 = 4 so D(-2.5,4)

The coordinate of the centroid will intersect 2:1 of the median from the vertex side.

Thus by intercept formula,

x = (2 × -2.5 + 1 × -2)/(2 + 1) and y = (2 × 4 + 1 × 7)/(2 + 1)

x = -2.33 and y = 5

So the coordinate of vertices will be (-2.33,5).

Hence "The specified triangle's centroid's coordinate will be at (-2.33,5)".

The volume of a specific weight of gas varies directly as the absolute temperature f and inversely as the pressure P.The volume is 1.29 m³.

According to the given information, the volume of a specific weight of gas varies directly with the absolute temperature (T) and inversely with the pressure (P). Mathematically, this can be expressed as V ∝ fT/P, where V represents the volume, f is a constant, T is the absolute temperature, and P is the pressure.

To find the volume when P is 433 kPa and T is 343 K, we can set up a proportion using the initial values. We have:

V₁/P₁ = V₂/P₂

Substituting the given values, we get:

1.23/479 = V₂/433

Solving this equation, we find V₂ ≈ 1.29 m³. Therefore, the volume is approximately 1.29 m³.

The relationship between the volume of a gas, its temperature, and pressure is described by the ideal gas law. According to this law, when the amount of gas and the number of molecules remain constant, increasing the temperature of a gas will cause its volume to increase proportionally. This relationship is known as Charles's Law. On the other hand, as the pressure applied to a gas increases, its volume decreases. This relationship is described by Boyle's Law.

In the given question, we are asked to determine the volume of gas when the pressure and temperature values change. By applying the principles of direct variation and inverse variation, we can solve for the unknown volume. Direct variation means that when one variable increases, the other variable also increases, while inverse variation means that when one variable increases, the other variable decreases.

In step one, we set up a proportion using the initial volume (1.23 m³), pressure (479 kPa), and temperature (344 K). By cross-multiplying and solving the equation, we find the value of the unknown volume when the pressure is 433 kPa and the temperature is 343 K. The answer is approximately 1.29 m³.

Answer:

36, 45

Step-by-step explanation:

Using equations you get \(x + x+9=81\) because one number is 9 more than the other and the sum is 81. Simplifying you get, \(2x = 72\). Divide both sides by 2 to get \(x=36\). Remember this is only x so to get the other number you have to add 9 to 36 to get 45 as the other number.

There are 350 different lineups that can be created.

The question here is regarding the possibility of different lineups given that there are two groups of players available - guards and forwards/centers. The coach wants to choose 2 of her guards and 3 of her forwards/ centers. To avoid an unbalanced lineup, she places the names of her 5 guards in one hat and the names of her 7 forwards/centers in a second hat. Then, she will randomly select 2 guards from the first hat and 3 forwards/ centers from the second hat.

In order to get the different possibilities of lineups, we need to calculate the total number of ways we can select the guards and the forwards/centers separately.

Total number of ways to select guards =\(5C_2 = (5 \times 4) / (2 \times 1) = 10\)

Total number of ways to select forwards/centers = \(7C_3 = (7 \times 6 \times 5) / (3 \times 2 \times 1) = 35\)

Thus, the total number of ways the lineup can be created is 10 × 35 = 350.

The probability of selecting at least one defective item at random is 0.3017.

The probability of an event occurring at least once will be calculated as the complement of the probability of the event never occurring. You can use exponents to multiply the number of events that occurred when calculating this amount.

Defect rate = P(defect) = 0.05

Probability is defined as the required outcome divided by the total number of possible outcomes.

P( at least 1 is defective) = 1 - P(none is defective)

P(not defective) = 1 - P(defective) = 1 - 0.05 = 0.95

P(none is defective) = P(non defective)^7

P(none defective) = 0.95× 0.95 × 0.95 × 0.95 × 0.95× 0.95× 0.95=0.6983

P(at least one is defective) = 1 - 0.6983 = 0.3017

Therefore, probability of at least one defective item is 0.3017.

Are you sure it's high school math?

Answer:

y = 2x - 4

Step-by-step explanation:

To solve this problem, we must first calculate the slope of the line AB using the formula:

\(\boxed{m = \frac{y_2 - y_1}{x_2 - x_1}}\)

where:

m ⇒ slope of the line

(x₁, y₁), (x₂, y₂) ⇒ coordinates of two points on the line

Therefore, for line AB with points A = (2, 5) and B = (4, 4) :

\(m_{AB} = \frac{5 - 4}{2 - 4}\)

⇒ \(m_{AB} = \frac{1}{-2}\)

⇒ \(m_{AB} = -\frac{1}{2}\)

Next, we have to calculate the slope of the line BC.

We know that the product of the slopes of two perpendicular lines is -1.

Therefore:

\(m_{BC} \times m_{AB} = -1\)      [Since BC and AB are at right angles to each other]

⇒ \(m_{BC} \times -\frac{1}{2} = -1\)

⇒ \(m_{BC} = -1 \div -\frac{1}{2}\)      [Dividing both sides of the equation by -1/2]

⇒ \(m_{BC} = \bf 2\)

Next, we have to use the following formula to find the equation of line BC:

\(\boxed{y - y_1 = m(x - x_1)}\)

where (x₁, y₁) are the coordinates of a point on the line.

Point B = (4, 4) is on line BC, and its slope is 2. Therefore:

\(y - 4 =2 (x - 4)\)

⇒ \(y - 4 = 2x - 8\)         [Distributing 2 into the brackets]

⇒ \(y = 2x-4\)

Therefore, the equation of line BC is y = 2x - 4.

The triangles ΔKLM and ΔEFG can be proven similar using both SSS and SAS similarity theorems.

In this question, we need to determine whether the triangles can be proven similar using the SSS or SAS similarities theorems.

For given diagrams,

(a) The table clearly shows distance gets smallers as time passes, so the first choice is correct.

Since we know the rate at which the escalator moves is constant, we know that the average rate of change of the escalator's distance from the first floor is the same across any time interval we choose. Take for instance the average rate of change from \(t=6\) to \(t=9\). If \(d(t)\) denotes distance at time \(t\), then the average rate of change over these 3 seconds, and at every point in time for that matter, is

\(\dfrac{d(9) - d(6)}{9 - 6} \dfrac{\rm cm}{\rm s} = \dfrac{890 - 980}{9 - 6} \dfrac{\rm cm}{\rm s} = -30 \dfrac{\rm cm}{\rm s}\)

In other words, the distance from the first floor is decreasing at a rate of 30 cm/s. (negative sign = decreasing)

(b) At the start, when \(t=0\), suppose Alan's distance from the first floor was \(x\). For every second that passes, we know the distance from the first floor decreases by 30 cm. This would mean that after \(t\) seconds have passed, the distance would have decreased by a total \(30t\) cm.

This tells us that Alan's distance from the first floor at any time \(t\ge0\) is

\(d(t) = x - 30t\)

Using any of the values from the table, we can solve for \(x\).

\(t=6 \implies d(6) = x - 30\cdot6 \implies 980 = x - 180 \implies x = 1160\)

which places Alan 1160 cm = 11.6 m from the first floor at the start.

The statement that is true of the sample size for nonprobability samples is that it is typically small.

Nonprobability sampling methods are often used when it is not feasible or practical to obtain a large sample that is representative of the population.

Nonprobability samples are selected based on criteria other than random selection, such as convenience, judgment, or purposive sampling. These methods are commonly used in qualitative research or when studying hard-to-reach populations.

Since nonprobability samples do not guarantee representativeness, the focus is often on in-depth exploration rather than generalization to a larger population. As a result, researchers often work with smaller sample sizes that are more manageable and allow for in-depth analysis of the selected cases or individuals.

F(3) is equal to 9, based on the given table and the corresponding values of x and f(x). Option D.

To find the value of F(3) based on the given table, we look at the corresponding x-value of 3 and find its corresponding f(x) value.

From the table, we see that when x = 3, f(x) = 9. Therefore, F(3) = 9.

The table shows the values of x and their corresponding f(x) values. We can see that when x increases by 1, f(x) also increases by 3. This indicates that the function has a constant rate of change, where the change in f(x) is always 3 units for every 1 unit change in x.

Given that F(3) represents the value of the function when x = 3, we look at the x-values in the table and find the corresponding f(x) value. In this case, when x = 3, f(x) = 9.

Therefore, the value of F(3) is 9. Option D is correct.

The counterclockwise circulation around c is 12 and the outward flux through c is zero.

Green's theorem is a useful tool for calculating the circulation and flux of a vector field around a closed curve in two-dimensional space.

In this case,

we have a field f=(7x−4y)i+(9y−4x)j and

a square curve c bounded by x=0, x=4, y=0, y=4.

To find the counterclockwise circulation, we can use the line integral of f along c, which is equal to the double integral of the curl of f over the region enclosed by c.

The curl of f is given by (0,0,3), so the line integral evaluates to 12.

To find the outward flux, we can use the double integral of the divergence of f over the same region, which is equal to zero since the divergence of f is also zero.
