Answer:

360=297+(x-36)+25

360=297+25-36+x

360=286+x

360-286=x

74=x

Answer:

x = 74 degree

Step-by-step explanation:

All those angles must add up to 360 degrees:

360 degrees  =  (297 + x - 36 + 25) deg, or

360 = 297 - 36 + 25 + x, or

x = 74 degrees

Step-by-step explanation:

You can say that a function take input and outputs something back. for example, let's y = X + 3. You may think this is a equation.Yeah it is but it is also a function. The original function notation is for example f(X) = X+3.But we set y = f(X) so it turn out to be y=X+3.Basically these two have the same meaning.X is a input in the function above.If you set X= 5,the input is now 5 and you will get a kinda output of 5+3 =8.so y= 8 or f(5) = 8.That's all.You can check out more on the internet.

Answer:

  (x, y) = (-3, -5)

Step-by-step explanation:

You want to solve the given system of equations by elimination.

To eliminate a variable from the equations, we need to add them in such a way that the coefficients for one of the variables have a total of zero.

Here, we observe that the y-coefficients are the same, so subtracting one equation from the other will cancel the y-terms. We want the result of that subtraction to give an equation with x having a positive coefficient, so we elect to subtract the second equation from the first:

  (2x -3y) -(-5x -3y) = (9) -(30)

  7x = -21 . . . . . simplify (y-terms are gone, x-term has positive coefficient)

  x = -3 . . . . . . . divide by 7

The value of y can be found from either equation. We choose to use the first one:

  2x -3y = 9

  2(-3) -3y = 9 . . . . . . substitute -3 for x in the first equation

  -15 = 3y . . . . . . add 3y-9

  -5 = y . . . . . . . divide by 3

The solution is (x, y) = (-3, -5).

The correlation that demonstrates the weakest correlation between two variables is option a) +.20.

Among the given options, the correlation that demonstrates the weakest correlation between two variables is option b) -50.

In correlation coefficients, the value ranges from -1 to +1, where -1 represents a perfect negative correlation, +1 represents a perfect positive correlation, and 0 represents no correlation or a very weak correlation.

Let's analyze the options provided:

a) +.20:

This indicates a positive correlation, but the value is relatively small (0.20).

It suggests a weak positive relationship between the variables.

b) -50:

This option appears to be a typographical error since the correlation coefficient cannot be negative 50.

Assuming it is meant to be -0.50, this indicates a moderate negative correlation.

c) +.75:

This option represents a strong positive correlation.

With a coefficient of 0.75, it suggests a relatively strong positive relationship between the variables.

d) -76: Similar to option b, this value appears to be a typographical error. A correlation coefficient cannot exceed the range of -1 to +1.

Assuming it is meant to be -0.76, this indicates a strong negative correlation.

Comparing the given options, the weakest correlation is option b) -50, assuming it was intended to be -0.50. A correlation coefficient of -0.50 represents a moderate negative correlation, which is weaker than the other options but still indicates some relationship between the variables.

If we were to measure a dependent variable's frequency, the appropriate method would be to count the number of times it occurred.

Frequency refers to the rate at which a behavior or event happens within a given timeframe. By counting the occurrences of the dependent variable, we can determine how often it happens or the number of times it is observed. The other options mentioned—timing the interval between responses, measuring the shape of the behavior, and timing how long it took to achieve—are not directly related to measuring frequency.

Timing the interval between responses would be more relevant for measuring the interresponse time or the duration between two consecutive instances of the behavior. Measuring the shape of the behavior would involve analyzing the pattern or characteristics of the behavior, such as its intensity or duration. Timing how long it took to achieve something would focus on the duration or latency of the behavior rather than its frequency.

Therefore, the correct approach for measuring frequency would be to count the number of occurrences of the dependent variable, providing an objective and quantitative assessment of how frequently the behavior or event takes place.

Pam should assess the response rate, analyze potential reasons for the low rate, and consider implementing alternative strategies to improve participation and ensure the reliability and validity of her survey results. Based on the information provided, Pam conducted a survey study and received an initial response rate of approximately 34%. After sending a second mailing, she obtained an additional 6% response rate.

Given this data, there are a few suggestions for Pam:

1. Evaluate the overall response rate: The combined response rate from both mailings would be approximately 34% + 6% = 40%. Pam should assess whether this response rate meets her desired objectives. If the response rate is satisfactory, she can proceed with analyzing the collected data. However, if the response rate is below expectations, further actions might be needed.

2. Investigate reasons for the low response rate: It's crucial for Pam to analyze why the response rate is relatively low. Possible factors could include the nature of the survey, the target audience, the content of the mailing, or the timing of the survey. Understanding the underlying causes can help Pam identify potential improvements for future surveys.

3. Consider additional strategies: To improve the response rate, Pam can explore alternative methods to engage participants. This could involve utilizing multiple communication channels, such as online surveys, follow-up phone calls, or incentives to encourage participation. Testing different approaches and measuring their effectiveness can provide valuable insights for future survey studies.

4. Ensure sample representativeness: Pam should also assess whether the obtained responses represent the target population accurately. If there are concerns regarding sample bias or representativeness, she may need to implement sampling techniques or adjust her survey methodology to obtain a more representative sample.

My calculator said that is the answer !

The value of k is determined to be -ln(5/14) / 4, and the exponential function to predict the drug concentration is C(t) = C₀ * e^((-ln(5/14) / 4) * t).

This equation allows for the estimation of the concentration in micrograms/milliliter at any time t after a 1000 mg dosage.

To find the value of k and write an equation for an exponential function, we can use the given information about the drug concentration at different times after the dosage.

Let's denote the time in hours as t and the concentration in micrograms/milliliter as C(t). According to the problem, at t = 1 hour, the concentration is 14 mcg/mL, and at t = 5 hours, the concentration is 5 mcg/mL.

The general form of an exponential decay function is C(t) = C₀ * e^(-kt), where C₀ is the initial concentration and k is the decay constant that we need to determine.

Using the given information, we have the following two equations:

14 = C₀ * e^(-k * 1)   -- equation 1

5 = C₀ * e^(-k * 5)    -- equation 2

Dividing equation 2 by equation 1, we get:

5/14 = (C₀ * e^(-k * 5)) / (C₀ * e^(-k * 1))

5/14 = e^(-k * (5-1))

5/14 = e^(-4k)

To solve for k, we take the natural logarithm (ln) of both sides:

ln(5/14) = -4k

Now we can solve for k by dividing both sides by -4:

k = -ln(5/14) / 4

Once we have the value of k, we can write the equation for the exponential function:

C(t) = C₀ * e^(-kt)

Substituting the obtained value of k, the equation becomes:

C(t) = C₀ * e^((-ln(5/14) / 4) * t)

This equation can be used to predict the concentration of the drug, in micrograms/milliliter, at any given time t (in hours) after a 1000 mg dosage.

Slope is the ratio of "rise" to "run" for a line. If the line is vertical, the "run" is zero, making the denominator of the ratio is zero. Division by zero gives an "undefined" result.

If the slope of a line is "undefined", it is a vertical line. It has the same x-value everywhere. Its equation is ...
