Answer:
RT = 23
Step-by-step explanation:
We will have a line that essentially goes like this:
R-----S-----T
The distance from R to S is 12 units.
The distance from S to T is 11 units.
We need to find the distance from R to T.
R is the starting point and T is the ending point.
To find the total distance, we can add both line lengths.
12 + 11 = 23 units

What Z-score value separates the top 70% of a normal distribution from the bottom 30%? a. z=0.52
c. z=-0.52 b. z=0.84 d. 2= -0.84 10.
Answers
The area to the left of the z-score corresponds to the cumulative probability up to that point. The correct answer is b. z=0.84.
To find the z-score that separates the top 70% from the bottom 30%, we need to look up the corresponding percentile in a standard normal distribution table.
The area to the left of the z-score corresponds to the cumulative probability up to that point. For example, if we look up a z-score of 0.84 in the table, we find that the area to the left of that value is 0.7995, or 79.95%.
Since we want to find the value that separates the top 70% from the bottom 30%, we subtract 0.30 (or 30%) from 1.00 to get 0.70 (or 70%). We then find the z-score that corresponds to that area, which is approximately 0.84.
Therefore, the answer is b. z=0.84.
To find the Z-score value that separates the top 70% of a normal distribution from the bottom 30%, you need to look for the Z-score corresponding to the 70th percentile. In this case, the correct answer is:
b. z=0.52
Here's a step-by-step explanation:
1. Determine the percentile you're looking for, which is the 70th percentile (separating the top 70% from the bottom 30%).
2. Consult a Z-score table or use a calculator to find the Z-score corresponding to the 70th percentile.
3. The Z-score for the 70th percentile is approximately 0.52.

The theater director recorded the number of seats occupied at past performances and the total revenue per
performance.
After plotting her results, the director noticed that the relationship between the two variables was fairly linear,
so she used the data to calculate the following least squares regression equation for predicting the total
revenue, in dollars, from the number of seats occupied.
= -325 + 143
What is the residual of a performance with a revenue of $700 and 70 seats occupied ?
Answers
The residual of a theatre performance with a revenue of $700 and 70 seats occupied is 45.
What is the residual of the performance?From the information illustrated, the theater director recorded the number of seats occupied at past performances and the total revenue per performance.
The equation is given as:
y = -325 + 14x
y = actual performance for 70 seats occupied
For x = 70
y = -325 + 14x
= 325 + 14(70)
= -325 + 980
= 655
Therefore, the residual will be:
= 700 - 655
= 45
The residual is 45.

C. ŷ = -157 +40.2x; no, because the r-value is low.
D. ŷ = 40.2 - 157x; no, because the r-value is low.
Answers
the correct answer is B. ŷ = -157 + 40.2x; yes, because the r-value is high. The regression line would be a good predictor of other data points because of the strong linear relationship between x and y, as indicated by the high r-value.
To determine the line of regression, we can use linear regression analysis. The regression line is a straight line that best represents the relationship between the two variables. It is determined by minimizing the sum of squared deviations between the observed values and the predicted values of the response variable.
Using a calculator or statistical software, we can find that the regression line for this data set is:
ŷ = -22.2933 + 32.0472x
The r-value (correlation coefficient) for this data set is 0.969, which is relatively high. This indicates a strong positive linear relationship between x and y.

There are 7 degrees of freedom for the pooled-variance t-test.
To perform a pooled-variance t-test, we need to calculate the degrees of freedom. The formula for degrees of freedom in a pooled-variance t-test is:
\(\[\text{{df}} = n_1 + n_2 - 2\]\)
where \(\(n_1\)\) and \(\(n_2\)\) are the sample sizes of the two independent samples.
In this case, \(\(n_1 = 4\)\) and \(\(n_2 = 5\)\). Substituting these values into the formula, we get:
\(\[\text{{df}} = 4 + 5 - 2 = 7\]\)
In a pooled-variance t-test, we combine the sample variances from two independent samples to estimate the population variance. The degrees of freedom for this test are calculated using the formula \(df = n1 + n2 - 2\), where \(n_1\)and \(n_2\) are the sample sizes of the two independent samples.
To understand why the formula is \(df = n1 + n2 - 2\), we need to consider the concept of degrees of freedom. Degrees of freedom represent the number of independent pieces of information available to estimate a parameter. In the case of a pooled-variance t-test, we subtract 2 from the total sample sizes because we use two sample means to estimate the population means, thereby reducing the degrees of freedom by 2.
In this specific case, the sample sizes are \(n1 = 4\) and \(n2 = 5\). Plugging these values into the formula gives us \(df = 4 + 5 - 2 = 7\). Hence, there are 7 degrees of freedom for the pooled-variance t-test.
Therefore, there are 7 degrees of freedom for the pooled-variance t-test.

Alice and Bob have just met, and wonder whether they have a mutual friend. Each has 50 friends, out of 1000 other people who live in their town. They think that its unlikely that they have a friend in common, saying each of us is only friends with 5% of the people here, so it would be very unlikely that our two 5%s overlap. Assume that Alices 50 friends are a random sample of the 1000 people (equally likely to be any 50 of the 1000), and similarly for Bob. Also assume that knowing who Alices friends are gives no information about who Bobs friends are.
(a) Compute the expected number of mutual friends Alice and Bob have.
(b) Let X be the number of mutual friends they have. Find the PMF of X.
(c) Is the distribution of X one of the important distributions we have looked at? If so, which?
Answers
The expected number of mutual friends Alice and Bob have is 2.5.
In the scenario described, Alice and Bob each have 50 friends out of 1000 people in their town. They believe that the probability of having a mutual friend is low since each of them is only friends with 5% of the population. To calculate the expected number of mutual friends, we can consider it as a matching problem.
Alice's 50 friends can be thought of as a set of 50 randomly selected people out of the 1000, and similarly for Bob's friends. The probability of any given person being a mutual friend of Alice and Bob is the probability that the person is in both Alice's and Bob's set of friends.
Since the selection of friends for Alice and Bob is independent, the probability of a person being a mutual friend is the product of the probability that the person is in Alice's set (5%) and the probability that the person is in Bob's set (5%). Therefore, the expected number of mutual friends is \(0.05 * 0.05 * 1000 = 2.5\).

The term "most specifically" is used to indicate the option that is the most specific or narrowest in meaning among the choices. Let's examine each option in the context of geometry:
a. A minor arc: A minor arc is a portion of a circle that measures less than 180 degrees. It is not the most specific term because it encompasses a range of arc sizes smaller than a semicircle, but it does not provide a narrower definition than other options.
b. A major arc: A major arc is a portion of a circle that measures more than 180 degrees. Similar to a minor arc, it does not provide the narrowest definition among the options.
c. A semicircle: A semicircle is a half of a circle, dividing it into two equal halves. This option is more specific than both minor and major arcs because it refers to a precise geometric shape with a 180-degree angle. However, there is one more option left to consider.
d. A chord: A chord is a straight line segment that connects two points on a circle. It is the most specific option among the choices because it refers to a specific geometric element—a line segment—within a circle.

the most recent earthquake in texas reached a magnitude of 3.3 on the richter scale. determine the seismograph reading of the earthquake. using M(I)=log (I/.001)
Answers
The seismograph reading of the earthquake is approximately 1.99526.To determine the seismograph reading of the earthquake with a magnitude of 3.3 on the Richter scale, we can use the formula M(I) = log(I/0.001), where M(I) represents the magnitude and I represents the intensity of the earthquake.
In this case, we are given the magnitude of 3.3. Let's substitute this value into the formula and solve for I:
3.3 = log(I/0.001)
To isolate I, we need to convert the equation into exponential form:
10^(3.3) = I/0.001
Simplifying the equation, we have:
I = 10^(3.3) * 0.001
Using a calculator, we find that 10^(3.3) is approximately 1995.26.
So, the seismograph reading of the earthquake is:
I = 1995.26 * 0.001
≈ 1.99526.

Suppose the mean percentage in Algebra 2B is 70% and the standard deviation
is 8%. What percentage of students receive between a 70% and 94% Enter the
value of the percentage without the percent sign.
HELP PLEASE!!
Answers
Answer:
49.87%
Step-by-step explanation:
We solve using z score formula
z = (x-μ)/σ, where
x is the raw score
μ is the population mean = 70%
σ is the population standard deviation = 8%
a) For x = 70%
z = 70% - 70%/8%
z = 0
Probability value from Z-Table:
P(x = 70) = 0.5
b) For x = 70%
z = 94% - 70%/8%
z = 3
Probability value from Z-Table:
P(x = 94) = 0.99865
The probability of students that receive between a 70% and 94%
P(x = 94) - P(x = 70)
0.99865 - 0.5
0.49865
Therefore, the percentage of students that receive between a 70% and 94% is
0.49865 × 100

Only a can be irrational
Both q and must be irrational

Answers
Answer:
only q or r can be irrational
Step-by-step explanation:
Rational numbers are numbers that can be expressed in the form a/b, where both a and b are integers and b ≠ 0. The decimal representation of an rational numbers either repeats the sequence of digits over again or terminates at a finite number.
Irrational numbers are numbers that are not rational. The decimal representation of an irrational number does not repeat a sequence of digits over again and never terminates. e.g √2, π.
The product of two irrational numbers is a rational number, the product of two rational numbers is a rational number while the product of a rational and irrational number is an irrational number. Hence since in p*q*r is an irrational number and p is a rational number, If both q and r are irrational then:
q*r = irrational * irrational = rational
p*(q*r) = rational * rational = rational. Since the result is not an irrational number then both q and r cannot be irrational.
But, If either q and r are irrational then:
q*r = irrational * rational = rational * irrational = irrational
p*(q*r) = rational * irrational = irrational. Since the result is an irrational number then only q or r can be irrational

Relational databases are heavily based on the mathematical concept of: Set Theory. The correct option is (A).
Relational databases are based on the principles of set theory, which deals with sets of elements and their relationships with each other. In a relational database, data is organized into tables, with each table representing a set of related data.
The tables are then related to each other through the use of keys, which allow for the establishment of relationships between different sets of data. The principles of set theory also govern the use of operations such as union, intersection, and difference, which can be used to manipulate the data in the tables.
Therefore, the mathematical concept of set theory is a fundamental part of the design and use of relational databases.

If you take the root of a number to a specific number, then square that by the same number you took the root by, then you will have the same number you started with. In this case, \(\sqrt[3]{729}\) equals 9, and \(9^{3}\) equals 729, so \((\sqrt[3]{729} )^{3}\) equals 729. 729 + 24 = 753, so that is the simplified answer.
