Step-by-step explanation:

\(area \: = length \: \times width \\ area = 2130 \\ width = 30 \\ 2130 = length \times 30 \\ 2130 = 30l \\ length = 71 \\ \\ perimeter = (length + width)2 \\ (71 + 30) 2 \\ = (101)2 \\ perimeter \: = 202\)

An estimation can be made that a student relying purely on guessing can achieve a score of approximately 11 or 12 correct responses in the examination.

Considering the availability of four plausible choices for each query, the probability of untargeted guessing to yield a correct answer for any given question is a quarter (1/4).

It is notable that, in light of the mutual exclusivity and independence of the guesses, the number of accurate predictions can be effectively represented through a binomial distribution. Within this framework, the probability of success (p) is equated to 1/4, while the sample size (n) is 47.

The arithmetical representation of the average of a binomial distribution characterized by variables n and p is np, attained through conventional statistical principles. Consequently, it is possible to formalize the expected value of the aggregate quantity of precise suppositions that a pupil is capable of generating as follows:

The calculation of the mean value of a numerical dataset can be represented by the symbol 'mean'. This value can be determined by multiplying the total number of observations contained within the dataset, denoted by 'n', by the probability of a specific event taking place, referred to as 'p'. In the present scenario, presuming the value of n to be 47 and p to be 1/4, the arithmetic mean of the dataset can be ascertained as 11.75.

Drawing on statistical probabilities, it is possible to approximate that a student who relies solely on chance to answer the examination questions may attain a score of roughly 11 or 12 correct responses.

Step-by-step explanation:

Because both triangles have the same side connected to, which means that that side is congruent to each other and because it tells us that JL and JK are congruent and KM and ML are congruent that means that its sss. Also, it is not giving us an angle to find the congruence so it has to be sss.

Answer:

30.2 meters

Step-by-step explanation:

The key is to realize that a 30 60 90 triangle can be constructed and the height of the house can be found from there. It may be helpful to draw a diagram.
I will use the diagram attached for reference to this solution.

Remember that the answer is asking for y, or the length of DE.

The angle CAB is 30 degrees, and the angle ACB is 90 degrees
The length of CB is 25 * sqrt3
Since ACB is a 30 60 90 triangle, and we know the length of one of the sides, the length of the other sides can be calculated.
CB is the shortest length, and so the middle length, AC, is sqrt(3) times longer than the length of the shortest length, CB

CB's length * sqrt 3 = AC's length = 25 * sqrt3 * sqrt3

AC = 75

length of A to F (I can't combine the letters a and f because then brainly thinks i'm swearing ) = 75 + x = 107

x = 32

Since length of BE = length of CF,

32 = BD + DE = 1.8 + y

y = 30.2 meters

Question: Sketch The Tetrahedron Enclosed By The Coordinate Planes And The Plane 2x+Y+Z=4. Use A Triple Integral To Find The Volume Of The tetrahedron

Answer:

1. C: y = 3x - 5

2. B: y = -3x - 9

Step-by-step explanation:

1.

y = 3x + 9; (2, 1) (parallel)

                 (x₁, y₁)

y - y₁ = m(x - x₁)

y - 1 = 3(x - 2)

y - 1 = 3x - 6

   +1         +1

-------------------

y = 3x - 5

----------------------------------------------------------------------------------------------------------

2.

y = (1/3)x - 6 ; (-3, 0) (perpendicular)

                     (x₁, y₁)

y - y₁ = m(x - x₁)

y - 0 = -3(x - (-3))

y - 0 = -3(x + 3)

y - 0 = -3x - 9

   +0          +0

----------------------

y = -3x - 9

I hope this helps!

Answer:

y + 3 = (6)(x - 6)

Step-by-step explanation:

The proper format for this equation y-1/6x+9 is y = (-1/6)x+9.

Any line perpendicular to y = (-1/6)x+9 has the slope which is the negative reciprocal of that of y = (-1/6)x+9, or the negative reciprocal of -1/6.  That is +6.  

Thus, the desired line, which passes through (6, -3), is found using the point-slope formula for the equation of a straight line:

y + 3 = (6)(x - 6)

There are several methods that can be used to verify the normality conditions for a scenario where a normal model is used to represent the distribution of sample means.

One common method is the visual inspection of a histogram or a normal probability plot. Another method is to use statistical tests such as the Shapiro-Wilk test or the Kolmogorov-Smirnov test to assess the normality of the sample data. Additionally, the sample size and the presence of outliers can also impact the normality conditions and should be taken into consideration when verifying normality.
Hi! To verify the normality conditions for the distribution of sample means, you should consider the following criteria:

1. Randomness: The sample data must be collected randomly to ensure independence of observations.
2. Sample size: The sample size should be sufficiently large (typically, n ≥ 30) to allow the Central Limit Theorem to apply.
3. Underlying distribution: If the population distribution is known to be normal, the sample means will also be normally distributed regardless of sample size.

These criteria help ensure the use of a normal model is appropriate in representing the distribution of sample means.

To evaluate the integral of e^(3x) / (1 + e^(3x)) dx, the best substitution to make is u = 1 + e^(3x).

Using this substitution, we can find du/dx = 3e^(3x), which implies dx = du / (3e^(3x)). Thus, the integral becomes:

integral of [e^(3x) / (1 + e^(3x))] dx = integral of [1 / (u-1)] (du / (3e^(3x)))

Now, we can replace the expression e^(3x) with (u-1) / u, and dx with du / (3e^(3x)), giving:

integral of [e^(3x) / (1 + e^(3x))] dx = integral of [1 / (u-1)] (du / (3(u-1))) = (1/3) ln|u-1| + C

Finally, we can substitute back u = 1 + e^(3x) to obtain:

integral of [e^(3x) / (1 + e^(3x))] dx = (1/3) ln|1+e^(3x)-1| + C = (1/3) ln|e^(3x)| + C = (1/3) (3x) + C = x + C, where C is the constant of integration.

For the height of a concrete foundation that is measured by a 15-inch base and an additional 2.5 inches of concrete that is being poured every minute between 0 and 10 minutes, the domain is [0, 10] and range is [15, 40].

The height of the concrete foundation at any time t (in minutes) is given by the function: h(t) = 15 + 2.5t. The domain of the function is the set of all possible input values (t) for the function. Here, the concrete is poured between 0 and 10 minutes. Hence, the domain is: [0, 10].

The range of the function is the set of all possible output values (h) for the function. Here, the base height of the foundation is 15 inches. Since, 2.5 inches is poured every minute, the height of the foundation increases linearly with time t. Therefore, the range of the function is: [15, 40]

Therefore, for this situation, the domain is [0, 10] and the range is [15, 40].

During the winter season, a family sets up a hot chocolate stand near a local ice skating rink. They sell cups of hot chocolate for $1.50 each and typically sell 50 cups per day.

However, due to changes in weather conditions and customer preferences, the family decides to conduct a market experiment by varying the price of hot chocolate to assess the impact on sales volume. The experiment involves increasing the price to $2.00 per cup and monitoring the resulting sales.

By increasing the price of hot chocolate from $1.50 to $2.00 per cup, the family aims to observe how the change in price affects the demand for their product. The experiment helps them understand the price elasticity of demand, which measures the responsiveness of quantity demanded to changes in price. If the increase in price leads to a significant decrease in sales volume, it suggests that the demand for hot chocolate is elastic, meaning consumers are sensitive to price changes. Conversely, if sales remain relatively stable despite the price increase, it indicates that the demand is inelastic, indicating that consumers are less sensitive to price changes. The family can analyze the results of this experiment to make informed pricing decisions and optimize their profitability during the winter season.

The vector parameterization of the tangent line to r(t) at the point P(2, 1, 3) is R(u) = (2i + j + 3k) + u(3i + j + 3k).

To find the vector parameterization of the tangent line to the curve defined by the vector function r(t), we need to consider the point on the curve where the tangent line passes through. In this case, the point P(2, 1, 3) is given.

The vector form of the tangent line is given by R(u) = P + uT, where P is the position vector of the point P and T is the direction vector of the tangent line.

The position vector of the point P is P = 2i + j + 3k.

To find the direction vector of the tangent line, we differentiate the vector function r(t) with respect to t. The result gives us the derivative vector, which represents the direction of the tangent line at any given point on the curve.

Substituting t = 2 (since we want the tangent line at the point P), we get r'(2) = i + 4j + 12k.

Therefore, the direction vector of the tangent line is T = i + 4j + 12k.

Substituting the values of P and T into the vector form R(u) = P + uT, we get R(u) = (2i + j + 3k) + u(3i + j + 3k), which represents the vector parameterization of the tangent line to the curve at the point P(2, 1, 3).
