A data set contains three unique values. Which of the following must be true?
mean = median
median = midrange
median = midrange
none of these
If a data set contains three unique values, none of the given statements must be true.
The mean is the average of a data set, calculated by summing all values and dividing by the number of values. In a data set with three unique values, the mean will not necessarily be equal to the median, which is the middle value when the data set is arranged in ascending or descending order.
The median is the middle value in a data set when arranged in order. With three unique values, the median will not necessarily be equal to the midrange, which is the average of the minimum and maximum values in the data set.
Therefore, none of the statements "mean = median," "median = midrange," or "median = midrange" must hold true for a data set with three unique values.

Determine the equation of the line that passes through (-8,9) and (2,-6)
Express you answer as a fraction in lowest terms.
The equation of the line that passes through the points (-8, 9) and (2, -6) is y = (-3 / 2)x - 3.Given two points (-8, 9) and (2, -6). We are supposed to find the equation of the line that passes through these two points.
We can find the equation of a line that passes through two given points, using the slope-intercept form of the equation of a line. The slope-intercept form of the equation of a line is given by, y = mx + b,Where m is the slope of the line and b is the y-intercept.To find the slope of the line passing through the given points, we can use the slope formula: m = (y2 - y1) / (x2 - x1).Here, x1 = -8, y1 = 9, x2 = 2 and y2 = -6.
Hence, we can substitute these values to find the slope.m = (-6 - 9) / (2 - (-8))m = (-6 - 9) / (2 + 8)m = -15 / 10m = -3 / 2Hence, the slope of the line passing through the points (-8, 9) and (2, -6) is -3 / 2.
Now, using the point-slope form of the equation of a line, we can find the equation of the line that passes through the point (-8, 9) and has a slope of -3 / 2.
The point-slope form of the equation of a line is given by,y - y1 = m(x - x1)Here, x1 = -8, y1 = 9 and m = -3 / 2.
Hence, we can substitute these values to find the equation of the line.y - 9 = (-3 / 2)(x - (-8))y - 9 = (-3 / 2)(x + 8)y - 9 = (-3 / 2)x - 12y = (-3 / 2)x - 12 + 9y = (-3 / 2)x - 3.
Therefore, the equation of the line that passes through the points (-8, 9) and (2, -6) is y = (-3 / 2)x - 3. Thus, the answer is (-3/2)x - 3.

You can infer causality from a correlational result, but only when the r value is greater than ?A. 0B. 5C. 1
You can infer causality from a correlational result, but only when the r value is greater than:
C. 1
Causality refers to a situation in which one event causes another. When there is a correlation between two variables, it means that they tend to move in the same direction.
However, this does not necessarily mean that one event causes the other. In order for a correlation to indicate causality, the correlation coefficient (r) must be greater than 1. If the correlation coefficient is below 1, then there is not enough evidence to suggest that one event causes the other.
In addition, there are other factors that need to be considered when assessing causality from a correlational result.
For example, the strength of the relationship between the variables, the direction of the relationship, and the consistency of the results over time. It is also important to consider the context in which the research was conducted, as this may have an effect on the results.

Suppose that the weight of a sack of flour has a probability distribution with moment generating function MW (t) = 1/(1 − 3t) 2 . You purchase 2 sacks of flour. Assume that the weights of different sacks of flour are independently distributed. What is the variance of the total weight of flour sacks purchased?
The variance of the total weight of flour sacks purchased is 36.
Since the moment generating function of a random variable uniquely determines its moments, we can use the moment generating function MW(t) to find the mean and variance of the weight of one sack of flour.
The first derivative of the moment generating function is:
MW'(t) = 6t/(1 - 3t)³
Setting t = 0, we get the mean:
MW'(0) = 6(0)/(1 - 3(0))³ = 0
So the mean weight of one sack of flour is zero.
The second derivative of the moment generating function is:
MW''(t) = 54t²/(1 - 3t)⁴ + 18/(1 - 3t)³
Setting t = 0, we get the second moment:
MW''(0) = 54(0)²/(1 - 3(0))⁴ + 18/(1 - 3(0))³ = 18
So the variance of the weight of one sack of flour is 18.
Now, let X and Y denote the weights of the first and second sacks of flour, respectively. Since the weights are independently distributed, the variance of the total weight of flour sacks purchased is the sum of the variances:
Var(X + Y) = Var(X) + Var(Y) = 18 + 18 = 36
Therefore, the variance of the total weight of flour sacks purchased is 36.

You'll have to set this up as two separate problems. First, we want to take 15% off the original $20 bill. To do this, you're going to multiply 20 by .15, which gives you $3. So, 15% off $20 is $17.
Now, we want to find 7% of the new bill, so we're going to multiply 17 by .07 to get $1.19, and add it to the $17, making the final bill $18.19. You could also multiply $17 by 1.07 to get your final total without the extra step in the middle, but only do that once you're comfortable with the math.

The cost of putting sod on the yard is $1161.5
What exactly is a trapezoid?A trapezoid is a polygon that has just one pair of parallel sides. The two extra sides of a trapezoid, known as the legs, are not parallel.
The price is calculated by multiplying the area in square feet by the price per square foot.
The formula for a trapezoid's area is
A = (1/2)(\(b_{1}\) + \(b_{2}\))h.
where h represents height and \(b_{1}\) and \(b_{2}\) represent base lengths.
The area is
A = (1/2)(90 ft + 112 ft)(46 ft)
= 4646 \(ft^{2}\)
when the supplied information is filled in.
Given that each square foot costs $0.25,
the price for this many square feet (4646\(ft^{2}\) ) is $0.25/\(ft^{2}\) × $989.23.

The psychometric properties of the TFEQ were found to be satisfactory in obese men and women participating in the SOS study. These findings provide support for the use of the TFEQ as a reliable and valid tool for assessing eating behavior in this specific population.
The psychometric properties and factor structure of the Three-Factor Eating Questionnaire (TFEQ) in obese men and women were examined in the Swedish Obese Subjects (SOS) study. The TFEQ is a widely used tool that assesses eating behavior and has three main factors: cognitive restraint, uncontrolled eating, and emotional eating. The study aimed to evaluate the reliability and validity of the TFEQ in this specific population.
To assess the psychometric properties, the researchers measured internal consistency, which evaluates how consistently the items of the TFEQ measure the same construct. They also examined test-retest reliability, which determines the stability of the TFEQ scores over time. Additionally, the researchers assessed construct validity by investigating how well the TFEQ measures the intended constructs.
The study found that the TFEQ demonstrated good internal consistency, indicating that the items within each factor were measuring the same construct. The test-retest reliability of the TFEQ scores was also found to be satisfactory, indicating stability over time.
Regarding construct validity, the results supported the three-factor structure of the TFEQ in obese men and women. This suggests that the TFEQ effectively measures cognitive restraint, uncontrolled eating, and emotional eating in this population.
In conclusion, the psychometric properties of the TFEQ were found to be satisfactory in obese men and women participating in the SOS study. These findings provide support for the use of the TFEQ as a reliable and valid tool for assessing eating behavior in this specific population.

Oliver drove 278 miles in 4 hours how much hours does it take him to drive 139 miles
PLSSS HELP
Answer:
34.75 i think
Step-by-step explanation:
Answer:
\(\boxed {\boxed {\sf 2 \ hours}}\)
Step-by-step explanation:
Let's set up a proportion to solve. Use the following setup:
\(\frac {hours}{miles}=\frac{hours}{miles}\)
We know that it takes Oliver 4 hours to drive 278 miles.
\(\frac {4 \ hours}{278 \ miles}=\frac{hours}{miles}\)
We don't know how long it takes him to drive 139 miles. Therefore, we use the variable x for hours, because it is unknown.
\(\frac {4 \ hours}{278 \ miles}=\frac{x \ hours}{139 \ miles}\)
\(\frac {4 }{278 }=\frac{x \ hours}{139 }\)
We are solving for x, the hours it takes him to drive 139 miles. The variable must be isolated. It is being divided by 139 and the inverse of division is multiplication. Multiply both sides of the equation by 139.
\(139*\frac {4 }{278 }=\frac{x \ hours}{139 }*139\)
\(139*\frac {4 }{278 }={x }\)
\(2=x\)
It takes Oliver 2 hours to drive 139 miles.
