If you have a positive and a negative what does it make???

Based on your question, you are asking about the property of expressions a, b, and c, where a ≠ 0. If a ≠ 0, then a/c = b/c. This property states that if you divide two equal expressions by the same nonzero value, the resulting expressions are still equal.

If a is greater than 0, then a/c is also greater than 0 because c is positive. Similarly, b/c is also positive because both b and c are positive. Therefore, a/c is greater than b/c, which can be written as a/c > b/c.

The equation of the line is y = -(3/4)x - 6.

A line is a perfectly straight, one-dimensional shape that extends endlessly in both directions and has no thickness.

Given that, the line passes through the points (-4,-3) and has a slope of -3/4.

The equation of the line in point-slope form is:

y - y₁= m (x -x ₁)

Substitute (x₁,y₁) = (-4,-3) and m = -3/4 into the above equation,

y - (-3) = -3/4 (x - (-4))

y + 3 = -3/4 (x + 4)

y = -(3/4)x -3 -3

y = -(3/4)x - 6

Hence, the equation of the line is y = -(3/4)x - 6.

Step-by-step explanation:

To find the margin of error at a 90% confidence level, given n = 25, x-bar = 30, and s = 5, we can use the formula for the margin of error in estimating a population mean.

The margin of error can be calculated using the formula: Margin of Error = (Critical Value) * (Standard Deviation / sqrt(n)), where the critical value is determined based on the desired confidence level. For a 90% confidence level, the critical value can be found from the t-distribution table with degrees of freedom (n-1). Since n = 25, the degrees of freedom is 24. By looking up the critical value in the t-distribution table, the corresponding value is approximately 1.711. Plugging in the values, the margin of error can be calculated as (1.711) * (5 / sqrt(25)) = 1.711.

The middle 50% of the distribution for X, or the IQR, lies between 87 acres and 261 acres.

A measurement of the dispersion or variability of a dataset is the interquartile range (IQR). The 75th and 25th percentiles of the data, or the difference between the upper and lower quartiles, are used to define it. The range of the middle 50% of the data is represented by it, in other words.

The IQR is a reliable indicator of the spread of the data that, in comparison to the range or standard deviation, is less susceptible to outliers or extreme values. For this reason, it is valuable in statistics. It is frequently employed as a measure of variability when the data contains extreme values or when the distribution is not normal.

Given that, mean = 174 and standard deviation = 58 acres.

Using the quartile values we have:

Q1 = mean - (1.5 * standard deviation)

Q1 = 174 - (1.5 * 58) = 87 acres

Q3 = mean + (1.5 * standard deviation)

Q3 = 174 + (1.5 * 58) = 261 acres

Hence, the middle 50% of the distribution for X, or the IQR, lies between 87 acres and 261 acres.

Iyell will save $7.68 on a classical music CD that has a price of $23.99.

Off means in market - The actual price of the objects/things will be different from the marked price.

Coupon means in market - The actual price of the objects/things will get reduced after applying the coupon.

For example:

1. 20% off on $60.

so, the price of $60 will get reduced by 20%

20% of $60 = ( 20x60 ) /100 = $12

actual price will be $60 - $12 = $48

Here, we have given that the marked price of CD is $23.99

First the 15% off sale will apply on the CD

15% of $23.99 = (15 x 23.99 ) / 100 = $3.5985

now, the price of CD will become, $23.99 - $3.5985 = $20.3915

now, to get maximum discount Iyell will apply the coupon for 20% extra off.

20% of $20.3915 = $4.0783

then, the actual price of CD will become, $20.3915 - $4.0783 = $16.3132

"The interval level of measurement is most appropriate because the data can be ordered, differences can be found and are meaningful, and there is no natural starting zero point" is the correct answer. Thus, option A is correct.

The most appropriate level of measurement for the given data, where the mean is zero and the increments of measurement are equal, is the interval level of measurement.

The interval level of measurement is characterized by data that can be ordered and where the differences between values are meaningful, but there is no natural starting zero point. In this case, the stress scores can be ordered, and the differences between scores have significance.

However, the absence of a natural starting zero point means that the value of zero does not represent the absence of stress, but rather a reference point within the measurement scale. To further illustrate this, let's consider an example of stress scores: -4, -2, 0, 2, 4.

The differences between adjacent scores are equal, with an increment of 2. However, the value of zero does not indicate the complete absence of stress but rather a point of reference within the scale. It is not meaningful to say that someone with a stress score of -2 has twice as much stress as someone with a score of -1.

On the other hand, if the data had a natural starting point where zero represented the absence of stress and ratios between scores were meaningful, the ratio level of measurement would be appropriate. However, since the data in question lacks a natural zero point, the ratio level is not applicable.

In summary, the interval level of measurement is most appropriate for the given data, where the mean is zero and the increments of measurement are equal. This level of measurement allows for ordering the data and meaningful differences between scores but does not provide a natural starting zero point.

Therefore, the correct answer is A. The interval level of measurement is most appropriate because the data can be ordered, differences can be found and are meaningful, and there is no natural starting zero point.

The truth value of the ~[P v (Q v R)] >~ (S v P) is true.

Truth-value, in logic, is the degree to which a particular proposition or assertion is true (T or 1) or false (F or 0). Because the truth-value of a compound proposition is a function of, or a quantity depending upon, the truth-values of its component components, logical connectives like disjunction and negation can be conceived of as truth-functions.

Given, ~[P v (Q v R)] >~ (S v P) since P v (Q v R) is true, thus ~ [ P v ( Q v R ) ] is false, therefore the implication is true.

The probability that a person who purchased the game did not see the advertisement is:0.659.

what is  probability?

Probability is a measure of the likelihood of an event occurring. It is expressed as a number between 0 and 1, with 0 indicating that the event is impossible and 1 indicating that the event is certain. Probability is used in many areas, including statistics, mathematics, science, finance, and gambling.

In the given question,

To solve this problem, we will use Bayes' theorem, which allows us to update our beliefs about the probability of an event based on new information.

Let A be the event that a person has seen the advertisement, and B be the event that a person has purchased the game. We want to find the probability of A given B, i.e., the probability that a person who has purchased the game has also seen the advertisement.

We know that P(A) = 0.24 (24% of the market has seen the advertisement), P(B|A) = 0.42 (42% of those who see the ad have purchased the game), and P(~A|~B) = 0.93 (93% of those who have not seen the advertisement have not purchased the game).

We can use the complement rule to find P(B|~A), the probability of purchasing the game given that the person has not seen the advertisement:

P(B|~A) = 1 - P(~B|~A) = 1 - 0.93 = 0.07

Now we can use Bayes' theorem:

P(A|B) = P(B|A) * P(A) / P(B)

where P(B) = P(B|A) * P(A) + P(B|~A) * P(~A)

Plugging in the values, we get:

P(B) = 0.42 * 0.24 + 0.07 * (1 - 0.24) = 0.2956

P(A|B) = 0.42 * 0.24 / 0.2956 = 0.3408

Therefore, the probability that a person who purchased the game did not see the advertisement is:

1 - P(A|B) = 1 - 0.3408 = 0.659

Rounded to the nearest thousandth, the answer is 0.659.

The first law of thermodynamics is a fundamental principle in physics that states energy cannot be created or destroyed, only converted from one form to another. It can be expressed in terms of heat and work through the equation:

ΔU = q - w

where ΔU represents the change in internal energy of a system, q represents the heat added to the system, and w represents the work done on or by the system.

Now, let's address when the quantities q and w would be negative numbers.

1) When q is negative: This occurs when heat is removed from the system, indicating an energy loss. For example, when a substance is cooled, heat is extracted from it, resulting in a negative value for q.

2) When w is negative: This occurs when work is done on the system, decreasing its energy. For instance, when compressing a gas, work is done on it, leading to a negative value for w.

In both cases, the negative sign indicates a reduction in energy or the transfer of energy from the system to its surroundings.

In summary, the first law of thermodynamics can be expressed as ΔU = q - w, and q and w can be negative numbers when energy is lost from the system through the removal of heat or when work is done on the system.
