Find the distance to walk along arc NQ pls help

Answer:

a.) they have the same slope

b.) they have different y-intersepts

c.) in the slope-intercept formula y = mx + b, m is the slope and b is the y-intercept. since the two equations have the same slope but different y-intercepts we can infer they are parallel.

The analogous equation for the square will be; (x-10)²=87.

Algebraic equations with equivalent solutions or roots are called equivalent equations.

Based on information provided, an equivalent equation is created by adding or deleting the same quantity or expression from both sides of a given equation;

Using the original equation as a starting point as;

-20x+ x² + 13 = 0

Now x² - 20x = -13.

We need to take the "x" term's coefficient, or b, to complete the square.

Then Divide by 2 and write the equation in the quadratic formula (ax² + bx + c = 0).Then,

B = -20

b/2 = -10

(b/2)² = 100

x² - 20x +100 = -13 + 100

On the left side,

LHS: (x + b/2)² = (x-10)2

RHS: -13 + 100 = 87

(x-10)² = 87

The implicit differentiation of x³y⁵ + 4x + 2xy = 1 is dy/dx = [(-3x²y⁵ - 2y - 4) / (x³ + 2x)] / (x³y⁵ + 2x)

To find dy/dx of the equation x³y⁵ + 4x + 2xy = 1 using implicit differentiation, we differentiate both sides of the equation with respect to x.

Differentiating x³y⁵ + 4x + 2xy = 1 with respect to x, we get:

d/dx (x³y⁵) + d/dx (4x) + d/dx (2xy) = d/dx (1)

Now, let's differentiate each term separately:

For the term x³y⁵, we use the product rule:

d/dx (x³y⁵) = 3x²y⁵ + x³ × d/dx (y⁵)

For the term 4x, the derivative is simply 4.

For the term 2xy, we use the product rule:

d/dx (2xy) = 2y + 2x × d/dx (y)

And the derivative of the constant term 1 is 0.

Putting it all together, we have:

3x²y⁵ + x³ × d/dx (y⁵) + 4 + 2y + 2x × d/dx (y) = 0

Now, we need to find d/dx (y) or dy/dx, which is our desired result.

Rearranging the terms, we get:

x³ × d/dx (y⁵) + 2x × d/dx (y) = -3x²y⁵ - 2y - 4

To isolate dy/dx, we divide through by (x³ + 2x):

[x³ × d/dx (y⁵) + 2x × d/dx (y)] / (x³ + 2x) = (-3x²y⁵ - 2y - 4) / (x³ + 2x)

Now, we substitute dy/dx = d/dx (y) into the equation:

x³ × dy/dx × y⁵ + 2x × dy/dx = (-3x²y⁵ - 2y - 4) / (x³ + 2x)

Finally, we can solve for dy/dx:

dy/dx = [(-3x²y⁵ - 2y - 4) / (x³ + 2x)] / (x³y⁵ + 2x)\

Below are just a few examples of demographic variables that can be measured at the interval level i.e. age, income, years of education, time spent, rating scale.

At the interval level of measurement, variables are measured on a scale with equal intervals between values, but without a true zero point. Several demographic variables can be measured at the interval level. Here are some examples:

Age: Age can be measured at the interval level, as the difference between two ages is meaningful (e.g., the difference between 20 and 30 is the same as the difference between 40 and 50).

Income: Income can be measured at the interval level, as the differences between income brackets or salary ranges are meaningful. However, it's important to note that income often has a skewed distribution and may be better analyzed using logarithmic transformations or categorized into income groups.

Years of Education: The number of years of education can be measured at the interval level. It represents the difference between educational levels (e.g., the difference between 10 years of education and 12 years of education).

Time Spent: Variables related to time spent on activities, such as time spent watching television per day or time spent exercising per week, can be measured at the interval level. The differences in time intervals are meaningful.

Rating Scales: Likert-type scales, where respondents rate their agreement or disagreement on a statement using a scale (e.g., strongly agree, agree, neutral, disagree, strongly disagree), can be considered as interval level measurements. Although the individual responses are ordinal, the overall scale can be treated as interval when analyzing data.

It's worth noting that some of these variables, although measured at the interval level, may be treated differently in statistical analysis depending on the specific research question and context.

The COP value for Rankine refrigeration cycle where Th=10°C and Tc=-20°C is -11.45.

The Rankine refrigeration cycle is a thermodynamic cycle that is commonly used in refrigeration. It uses a refrigerant to absorb heat from a cold space and release it into a warmer environment. The coefficient of performance (COP) is an important parameter that is used to measure the efficiency of a refrigeration cycle.

To calculate the COP value for Rankine refrigeration cycle where Th=10°C and Tc=-20°C, we can use the formula:

COP = QL/Wc

Where QL is the heat removed from the cold reservoir and Wc is the work done by the compressor.

We can calculate QL using the formula:

QL = mCp(Tc-Th)

Where m is the mass flow rate of the refrigerant, Cp is the specific heat capacity of the refrigerant, Tc is the temperature of the cold reservoir, and Th is the temperature of the hot reservoir.

Assuming that the mass flow rate of the refrigerant is 1 kg/s and the specific heat capacity of the refrigerant is 4.18 kJ/kg.K, we can calculate QL as:

QL = 1 x 4.18 x (-20-10) = -104.5 kW

(Note that the negative sign indicates that heat is being removed from the cold reservoir.)

We can calculate Wc using the formula:

Wc = m(h2-h1)

Where h2 is the enthalpy of the refrigerant at the compressor exit and h1 is the enthalpy of the refrigerant at the compressor inlet.

Assuming that the compressor is adiabatic and reversible, we can use the isentropic efficiency to calculate h2 as:

h2 = h1 + (h2s-h1)/ηs

Where h2s is the enthalpy of the refrigerant at the compressor exit for an isentropic compression process and ηs is the isentropic efficiency.

Assuming that the isentropic efficiency is 0.85, we can use a refrigerant table to find h1 and h2s for the given temperatures. For example, if we use R134a as the refrigerant, we can find h1 = -38.17 kJ/kg and h2s = -22.77 kJ/kg.

Substituting these values into the equation, we can calculate h2 as:

h2 = -38.17 + (-22.77+38.17)/0.85 = -29.04 kJ/kg

(Note that the negative sign indicates that work is being done by the compressor.)

Therefore, we can calculate Wc as:

Wc = 1 x (-29.04 - (-38.17)) = 9.13 kW

Finally, we can calculate the COP as:

COP = QL/Wc = -104.5/9.13 = -11.45

(Note that the negative sign indicates that the system is not a heat pump, but a refrigeration cycle.)Thus, the COP value for Rankine refrigeration cycle where Th=10°C and Tc=-20°C is -11.45.

Answer:

\(P(X_i=2) =\dfrac{1}{6}\)

\(P(X_i=-1) =\dfrac{5}{6}\)

Step-by-step explanation:

Given the numbers on the chips = 1, 1, 3 and 5

Miguel chooses two chips.

Condition of winning: Both the chips are same i.e. 1 and 1 are chosen.

Miguel gets $2 on winning and loses $1 on getting different numbers.

To find:

Probability of winning $2 and losing $1 respectively.

Solution:

Here, we are given 4 numbers 1, 1, 3 and 5 out of which 2 numbers are to be chosen.

This is a simple selection problem.

The total number of ways of selecting r numbers from n is given as:

\(_nC_r = \frac{n!}{r!(n-r)!}\)

Here, n = 4 and r = 2.

So, total number of ways = \(_4C_2 = \frac{4!}{2!\times 2!} = 6\)

Total number of favorable cases in winning = choosing two 1's from two 1's i.e. \(_2C_2 = \frac{2!}{2! 0! } = 1\)

Now, let us have a look at the formula of probability of an event E:

\(P(E) = \dfrac{\text{Number of favorable ways}}{\text{Total number of ways}}\)

So, the probability of winning.

\(P(X_i=2) =\dfrac{1}{6}\)

Total number of favorable cases for -1: (6-1) = 5

So, probability of getting -1:

\(P(X_i=-1) =\dfrac{5}{6}\)

The conclusion drawn from the data best describes a positive correlation between height and weight for the team.

The table represents the heights and weights of the starting offensive players for a high school varsity football team. The question is asking for the conclusion that best describes the correlation between height and weight for the team.
                            To determine the correlation between height and weight, we can look at the data in the table and see if there is a pattern or trend. We can do this by creating a scatter plot of the data points, with height on the x-axis and weight on the y-axis.
                             After analyzing the scatter plot, we can draw the conclusion that there is a positive correlation between height and weight for the team. This means that as height increases, weight tends to increase as well. The data points on the scatter plot should show a general upward trend.

In summary, the conclusion drawn from the data best describes a positive correlation between height and weight for the team.

The correlation between height and weight for the high school varsity football team can be described as positive, no correlation, or weak correlation based on the observations. Correlation only describes the relationship between the variables and does not imply causation or provide an explanation.

Based on the given table representing the heights and weights of the starting offensive players for a high school varsity football team, we can draw the following conclusion regarding the correlation between height and weight for the team:

1. Positive correlation: If we observe that as the heights of the players increase, their weights also tend to increase, then we can conclude that there is a positive correlation between height and weight. This means that taller players generally have higher weights, and vice versa.

2. No correlation: On the other hand, if we notice that there is no clear pattern or relationship between height and weight, with some tall players having low weights and vice versa, then we can conclude that there is no correlation between height and weight for the team.

3. Weak correlation: If there is a weak correlation between height and weight, it means that there is a slight tendency for taller players to have higher weights, but the relationship is not very strong or consistent. In this case, we might observe some tall players with lower weights and some shorter players with higher weights.

Correlation only describes the relationship between two variables, in this case, height and weight. It does not imply causation or explain why the correlation exists.

The probability that a random student will be taking both Algebra 2 and Chemistry is 0.0136 or 1.36%.

To find the probability that a random student will be taking both Algebra 2 and Chemistry, we need to use the concept of conditional probability.

Let's denote the event of taking Algebra 2 as A and the event of taking Chemistry as C. We are given that P(A) = 0.08 (8% probability of taking Algebra 2) and P(C|A) = 0.17 (17% probability of taking Chemistry given that the student is taking Algebra 2).

The probability of taking both Algebra 2 and Chemistry can be calculated using the formula for conditional probability:

P(A and C) = P(C|A) * P(A)

Substituting the given values:

P(A and C) = 0.17 * 0.08

P(A and C) = 0.0136

Therefore, the probability that a random student will be taking both Algebra 2 and Chemistry is 0.0136 or 1.36%.

It is important to note that the probability of taking both Algebra 2 and Chemistry is determined by the intersection of the two events, which means students who are taking both courses. In this case, the probability is relatively low, as it depends on the individual probabilities of each course and the conditional probability given that a student is taking Algebra 2.

Answer: x = 6

Step-by-step explanation: To solve for x, we must first

isolate the term containing x, which in this problem is 2x.

Since 4 is being added to 2x, we subtract 4

from both sides of the equation to isolate the 2x.

On the left, the +4 and -4 cancels

out and on the right, 16 - 4 is 12.

So we have 2x = 12.

Then just divide both sides by 2 so x = 6.
