When a right rectangular prism with a square base is sliced in a direction parallel to the base, the resulting cross section is a square.

The parallel plane will intersect all the edges of the square base at the same distance from the top face of the prism, creating a new square.

The size of the resulting square will depend on the distance between the plane and the top face of the prism. If the plane is closer to the top face, the resulting square will be larger. If the plane is further away, the resulting square will be smaller.

It is important to note that if the plane is not parallel to the base, the resulting cross section will be a rectangle. This is because the plane will intersect the edges of the base at different distances from the top face of the prism, creating a new rectangle.

Understanding the resulting cross section of a sliced right rectangular prism can be useful in real-world applications, such as in architecture and engineering, where precise measurements and cutting are necessary for construction projects.

The difference between r and p.  is that r represents the sample correlation coefficient while p represents the p-value

Generally, r represents the sample correlation coefficient, which is a measure of the strength and direction of the linear relationship between two variables in a sample of data. It ranges from -1 to 1, where -1 represents a perfect negative correlation, 0 represents no correlation, and 1 represents a perfect positive correlation.

p represents the p-value, which is a measure of the statistical significance of the sample correlation coefficient. It represents the probability that the observed correlation occurred by chance, assuming that there is no true correlation in the population.

A p-value of less than 0.05 is often used as a threshold for determining statistical significance, meaning that the observed correlation is unlikely to have occurred by chance and is likely to reflect a true correlation in the population.

Therefore, the interquartile range of the company scores for the reference population is approximately 26.96.

To find the interquartile range (IQR) of the intelligence scores for the reference population, we need to calculate the difference between the third quartile (Q3) and the first quartile (Q1).

Since the scores are normally distributed with a mean of 120 and a standard deviation of 20, we can use the properties of the normal distribution to determine the quartiles.

The first quartile, Q1, corresponds to the 25th percentile, which is located at z = -0.674. We can calculate the value of Q1 as:

Q1 = mean + z * standard deviation = 120 + (-0.674) * 20 = 120 - 13.48 = 106.52

Similarly, the third quartile, Q3, corresponds to the 75th percentile, which is located at z = 0.674. We can calculate the value of Q3 as:

Q3 = mean + z * standard deviation = 120 + (0.674) * 20 = 120 + 13.48 = 133.48

Finally, we can calculate the interquartile range (IQR) as the difference between Q3 and Q1:

IQR = Q3 - Q1 = 133.48 - 106.52 = 26.96

Answer:

11 if you mean x^2

Step-by-step explanation:

Since we are solving for x, we need to just get x by its self. The only thing we have to do is get rid of the exponent of (^2). to do this, we have to take teh square root of both sides:

The square root of x^2 is x

The square root of 121 is 11

So the asnwer is x = 11

Step-by-step explanation: A common mistake in this problem would be to say that if x² = 121, x must equal 11.

However, you must set the equation equal to 0 first.

So our first step is to subtract 121 from both sides to get x² - 121 = 0.

Next, factor the left side to get (x + 11)(x - 11) = 0

So either x + 11 = 0 or x - 11 = 0.

Solving each equation from here, we find that x = -11 or x = 11.

So our answer is not just 11, it's {11, -11}.

Taylor series is \(f(x) = ln2 + \sum_{n=1)^{\infty}(-1)^{n-1} \frac{(n-1)!}{n!(9)^{n}(x9)^{2} }\)

To find the Taylor series for f(x) = ln(x) centering at 9, we need to observe the pattern for the first four derivatives of f(x). From there, we can create a general equation for f(n). Starting with f(x), we have

f(x) = ln(x)

\(f^{1}(x)= \frac{1}{x} \\f^{2}(x)= -\frac{1}{x^{2} }\\f^{3}(x)= -\frac{2}{x^{3} }\\f^{4}(x)= \frac{-6}{x^{4} }\)

.

.

.

Since we need to have it centered at 9, we must take the value of f(9), and so on.

f(9) = ln(9)

\(f^{1}(9)= \frac{1}{9} \\f^{2}(9)= -\frac{1}{9^{2} }\\f^{3}(x)= -\frac{1(2)}{9^{3} }\\f^{4}(x)= \frac{-1(2)(3)}{9^{4} }\)

.

.

.

Following the pattern, we can see that for \(f^{n}(x)\),

\(f^{n}(x)=(-1)^{n-1}\frac{1.2.3.4.5...........(n-1)}{9^{n} } \\f^{n}(x)=(-1)^{n-1}\frac{(n-1)!}{9^{n}}\)

This applies for n ≥ 1, Expressing f(x) in summation, we have

\(\sum_{n=0}^{\infinite} \frac{f^{n}(9) }{n!} (x-9)^{2}\)

Combining ln2 with the rest of series, we have

\(f(x) = ln2 + \sum_{n=1)^{\infty}(-1)^{n-1} \frac{(n-1)!}{n!(9)^{n}(x9)^{2} }\)

Taylor series is \(f(x) = ln2 + \sum_{n=1)^{\infty}(-1)^{n-1} \frac{(n-1)!}{n!(9)^{n}(x9)^{2} }\)

Answer:

students' ratings of their professors' performance on a five-point scale ranging from poor to excellent

Step-by-step explanation:

There are four type of scales in mathematics. They include:

1. Nominal scale : they do not measure quantity. they are used to classify a population into two or more scales that are exhaustive and mutually exclusive. e.g. classifying a population based on gender, naming the different car brands seen in a school's parking lot

2. Ordinal scale : this scale measures ranks a population from best to worst or from least to most. e.g. ranking the participants of a race based on their performance

3. Interval scale : this scale has the property of order and equal intervals. Zero is not meaningful.

Interval scale is used when the difference between the numbers are meaningful. e.g. students' ratings of their professors' performance on a five-point scale ranging from poor to excellent Here a child who is scored 1, did very poorly and a child scored 5, performed excellently well.

4. Ratio scale :  this scale has the property of order, a meaningful zero and equal intervals.

The probability that the artist chosen will be a painter or a photographer is 3/4

Probability is the function that measures the chances that an outcome of a random event will be as expected. In this way you can measure how likely it is that an event will happen.

To solve this exercise the formula and the procedure that we have to use for probability is:

probability= (achieving success / possible outcomes)

Achieving success = 7 painters + 5 photographer = 12

Possible outcomes = 7 painters + 5 photographer + 4 sculptors = 16

Applying the formula to calculate the probability we get:

probability= (achieving success / possible outcomes)

probability= 12/16

Answer:

Step-by-step explanation:

First right out all the data in numerical order from left to right.

2, 2, 2, 3, 4, 5, 7

The median is the middle number in the set.  If there is an even amount of data points, find the average of the two middle numbers.  If there is an odd number of data points, like in this data set, just take the middle number as you median.

There are 7 data points in this set so the fourth number in the set written in numerical order would be your median.

When writing this set out in numerical order, repeated numbers must be repeated, we find that the fourth, or middle, number is 3.  Therefore, 3 is the median of this data set.

By using Dirac delta function, δ(c0sθ- cosθ)= δ(θ-θ’)/sin θ’= δ (θ- θ’)/ sin θ.

Here's how to show that δ(x^2-a^2)=1/2a[δ(x-a)+ δ(x+a)]

To show that δ(x^2-a^2)=1/2a[δ(x-a)+ δ(x+a)],

we can use the definition of Dirac delta function.

Dirac delta function is defined as follows:∫δ(x)dx=1and 0 if x≠0

In order to solve the given expression, we have to take the integral of both sides from negative infinity to infinity, which is given below:∫δ(x^2-a^2)dx=∫1/2a[δ(x-a)+ δ(x+a)]dx

To compute the left-hand side, we use a substitution u=x^2-a^2 du=2xdxWhen x=-a, u=a^2-a^2=0 and when x=a, u=a^2-a^2=0.

Therefore,-∞∫∞δ(x^2-a^2)dx=-∞∫∞δ(u)1/2adx=1/2a

Similarly, the right-hand side becomes:∫1/2a[δ(x-a)+ δ(x+a)]dx=1/2a∫δ(x-a)dx +1/2a∫δ(x+a)dx=1/2a + 1/2a=1/2a

Therefore,∫δ(x^2-a^2)dx=∫1/2a[δ(x-a)+ δ(x+a)]dxHence, δ(x^2-a^2)=1/2a[δ(x-a)+ δ(x+a)].

Next, we can show that δ(c0sθ- cosθ)= δ(θ-θ’)/sin θ’= δ (θ- θ’)/ sin θ as follows:We know that cosθ = cosθ' which implies θ=θ'+2nπ or θ=-θ'-2nπ.

Therefore, c0sθ-cosθ'=c0s(θ'-2nπ)-cosθ'=c0sθ'-cosθ' = sinθ'c0sθ-sinθ'cosθ'.

We can use the following identity to simplify the above expression:c0sA-B= c0sAcosB-sinAsinB

Therefore,c0sθ-cosθ' =sinθ'c0sθ-sinθ'cosθ'=sinθ'[c0sθ-sinθ'cosθ']/sinθ' =δ(θ-θ')/sinθ'

Hence,δ(c0sθ- cosθ)= δ(θ-θ’)/sin θ’= δ (θ- θ’)/ sin θ.

For path A, the total distance traveled is 480 meters. The magnitude of displacement from start to finish is 240 meters, and the direction of the displacement is southeast.

To determine the total distance traveled along path A, we add up the lengths of all the individual segments. Path A consists of two horizontal segments followed by two vertical segments, each of which is 120 meters long.  the total distance is 2 * 120 + 2 * 120 = 480 meters.

To calculate the magnitude of the displacement, we consider the straight-line distance from the starting point to the ending point. In this case, the displacement is equal to the length of the hypotenuse of a right triangle formed by the horizontal and vertical segments of path A. Using the Pythagorean theorem, we find the displacement to be sqrt((120)^2 + (120)^2) ≈ 169.7 meters.

The direction of the displacement can be determined by finding the angle between the displacement vector and the positive x-axis. In this case, the angle can be determined using trigonometry as arctan(120/120) ≈ 45 degrees. Since the displacement is in the southeast direction, the direction can be stated as 45 degrees southeast.
