Select the statement that best describes SST. Question 3 options: SST measures the variability of the actual data. SST measures the variability between the data and the best guess at a linear model of the data. A large SST guarantees that the independent and dependent variables are related. A low SST minimizes the error between the data's actual y values and the model's y values.
SST measures the variability of the actual data.
SST, or the Total Sum of Squares, is a statistical measure that quantifies the total variability observed in the data. It represents the total variation of the dependent variable (y) without considering any specific model or independent variables.
SST measures the dispersion or spread of the actual data points around their mean. It provides an overall assessment of the total variability present in the data set, regardless of any relationships or models. By calculating the sum of the squared differences between each data point and the mean of the data, SST captures the total variation or deviation from the mean value.
The other options presented do not accurately describe SST. While SST is related to the variability in the data, it does not measure the variability between the data and a linear model (that would be measured by SSE, or Sum of Squares Error). SST also does not guarantee the presence of a relationship between independent and dependent variables, nor does it aim to minimize the error between actual y values and model y values.
In summary, SST represents the total variation in the data and is a fundamental measure in statistical analysis. It provides insights into the overall spread or dispersion of the observed data points, regardless of any specific models or relationships.

Answer:

Step-by-step explanation:
You want to estimate the proportion of individuals in your area who think the public school system needs major overhauling. If you believe the proportion will be about 35%, how many individuals will you need to sample if you want a 95% margin of error to be no more than 3%? at least 30 at least 1068 at least 972
We cannot have a fraction of a person in the sample, we need to round up to the next whole number, which is 1022.
So, you will need to sample at least 1022 individuals to achieve a 95% confidence level with a margin of error no more than 3%.
This means that the correct answer among the given options is "at least 1068".
To estimate the sample size needed for survey, you can use the formula for sample size calculation in a proportion estimation problem.
The formula is:
\(n = (Z^2 * p * (1-p)) / E^2\)
where:
n = required sample size
Z = Z-score, which corresponds to the desired confidence level (1.96 for a 95% confidence level)
p = estimated proportion (0.35 in this case)
E = desired margin of error (0.03 in this case)
Now, let's plug the values into the formula:
\(n = (1.96^2 * 0.35 * (1-0.35)) / 0.03^2\)
n = (3.8416 * 0.35 * 0.65) / 0.0009
n = 0.919326 / 0.0009
n ≈ 1021.473.

prove that the following set is countable using a diagram and a formula for the one-toone correspondence function. {±1^1 , ±2^2 , ±3^3 , ±4^4 , ±5^5 , . . .}
The set {±1^1, ±2^2, ±3^3, ±4^4, ±5^5, ...} is countable. It can be proven by constructing a one-to-one correspondence between the set and the set of positive integers.
To establish a one-to-one correspondence, we can define a function f: ℕ → {±1^1, ±2^2, ±3^3, ±4^4, ±5^5, ...} as follows:
f(n) = (-1)^n * n^n
This function maps each positive integer n to the corresponding element in the given set. It alternates the sign based on the parity of n and raises n to the power of n. The function is one-to-one because each positive integer is uniquely mapped to an element in the set, and no two distinct positive integers are mapped to the same element.
By defining this one-to-one correspondence, we establish that the set {±1^1, ±2^2, ±3^3, ±4^4, ±5^5, ...} is countable, as it can be put into a one-to-one correspondence with the set of positive integers.

Vamos a resolver las operaciones utilizando la regla de multiplicación de fracciones y luego simplificaremos los resultados.
a) \(\sf\:\frac{1}{6} \times \frac{3}{4}\\\)
Para multiplicar estas fracciones, multiplicamos los numeradores entre sí y los denominadores entre sí:
Numerador: \(\sf\:1 \times 3 = 3\\\)
Denominador: \(\sf\:6 \times 4 = 24\\\)
Entonces, \(\sf\:\frac{1}{6}\:\times\:\frac{3}{4} = \frac{3}{24}\\\)
Podemos simplificar esta fracción dividiendo tanto el numerador como el denominador por el máximo común divisor, que en este caso es 3:
\(\sf\:\frac{3}{24} = \frac{3 \div 3}{24 \div 3} = \frac{1}{8}\\\)
Por lo tanto, el resultado simplificado es \(\sf\:\frac{1}{8}\\\).
b) \(\sf\:\frac{1}{2} \times \frac{2}{7}\\\)
Aplicando la regla de multiplicación de fracciones:
Numerador: \(\sf\:1 \times 2 = 2\\\)
Denominador: \(\sf\:2 \times 7 = 14\\\)
Entonces, \(\sf\:\frac{1}{2} \times \frac{2}{7} = \frac{2}{14}\\\)
Podemos simplificar esta fracción dividiendo tanto el numerador como el denominador por el máximo común divisor, que en este caso es 2:
\(\sf\:\frac{2}{14} = \frac{2 \div 2}{14 \div 2} = \frac{1}{7}\\\)
Por lo tanto, el resultado simplificado es \(\sf\:\frac{1}{7}\\\).
c) \(\sf\:\frac{4}{7} \times \frac{5}{6}\\\)
Siguiendo la regla de multiplicación de fracciones:
Numerador: \(\sf\:4 \times 5 = 20\\\)
Denominador: \(\sf\:7 \times 6 = 42\\\)
Entonces, \(\sf\:\frac{4}{7} \times \frac{5}{6} = \frac{20}{42}\\\)
Podemos simplificar esta fracción dividiendo tanto el numerador como el denominador por el máximo común divisor, que en este caso es 2:
\(\sf\:\frac{20}{42} = \frac{20 \div 2}{42 \div 2} = \frac{10}{21}\\\)
No podemos simplificar aún más esta fracción, por lo que el resultado simplificado es \(\sf\:\frac{10}{21}\\\).

the population of a city is expected to be people after years. find the average population between year and year .
The average population between year 1 and year 10 is approximately 55,555 people.
To find the average population between year X and year Y, we need to first calculate the total population increase over that time period. We can do this by subtracting the population in year X from the population in year Y.
Population increase = Population in year Y - Population in year X
Once we have the population increase, we can divide it by the number of years between X and Y to get the average annual population increase.
Average annual population increase = Population increase / (Y - X)
Finally, to find the average population between year X and year Y, we need to add the average annual population increase to the population in year X.
Average population = Population in year X + Average annual population increase
For example, if the population of a city is expected to be 100,000 people after 10 years, and we want to find the average population between year 1 and year 10, we would do the following:
Population in year 1 = X = 50,000 (let's say)
Population in year 10 = Y = 100,000
Population increase = 100,000 - 50,000 = 50,000
Number of years between X and Y = 10 - 1 = 9
Average annual population increase = 50,000 / 9 = 5,555.56 (rounded)
Average population = 50,000 + 5,555.56 = 55,555.56 (rounded)

The average population of the city between the starting year and 10 years later is estimated to be 625,000.
The average population of a city between two specific years, we will need to use the formula for calculating the arithmetic mean.
The sum of all the values divided by the number of values.
We will need to sum up the populations of the city for each year between the two given years and divide the result by the number of years included.
Let us assume that the population of the city in the year we are starting with is "P1" and the population after "n" years is "P2".
Therefore, the average population can be calculated as:
\(Average Population = (P1 + P2) / 2\)
The exact population figures for each year between the two given years, we will have to use an estimated population growth rate to make the calculation.
We can use the formula:
\(P2 = P1 \times (1 + r)^n\)
where "r" is the estimated annual growth rate and "n" is the number of years between the two given years.
Let's assume that the population of the city in the starting year is 500,000 and the estimated population after 10 years is 750,000. Using the formula, we can calculate the estimated annual growth rate as:
\(r = (P2 / P1)^{(1/n)} - 1 = (750,000 / 500,000)^{(1/10)} - 1 = 0.0473 or 4.73\%\)
The estimated annual growth rate, we can calculate the average population between the two given years using the formula:
\(Average Population = (P1 + P2) / 2 = (500,000 + 750,000) / 2 = 625,000\)
It is important to note that this is just an estimate based on the assumed growth rate, and the actual population may vary from this calculation.

Answer:
The inequality represented by the graph is y > \(\frac{1}{2}\) x + 2
Step-by-step explanation:
The form of the linear equation is y = m x + b, where
m is the slope of the lineb is the y-intercept (value y at x = 0)The rule of the slope is m = \(\frac{y2-y1}{x2-x1}\) , where
(x1, y1) and (x2, y2) are two points on the lineFrom the given figure
∵ The line passes through points (0, 2) and (2, 3)
∴ x1 = 0 and y1 = 2
∴ x2 = 2 and y2 = 3
→ Substitute them in the rule of the slope above
∵ m = \(\frac{3-2}{2-0}\) = \(\frac{1}{2}\)
∴ m = \(\frac{1}{2}\)
→ b is the value of y at x = 0
∵ At x = 0, y =2
∴ b = 2
→ Substitute the value of m and b in the form of the equation above
∵ y = \(\frac{1}{2}\) x + 2
∴ The equation of the line is y = \(\frac{1}{2}\) x + 2
∵ The line is dashed
∵ The shaded area is over the line
∴ The sign of inequality is >

∴ y > \(\frac{1}{2}\) x + 2
∴ The inequality represented by the graph is y > \(\frac{1}{2}\) x + 2

Step-by-step explanation:
So remember that you first need to solve for the parenthesizes, as it is the thing you need to do first in the order of operations: PEMDAS (Parenthesis, Exponents, Multiply, Divide, Add, Subtract)
So, what you should do first is distribute the 3 into x - 1 as well as the 2 on the right side into 2x + 3.
7x-3(x-1) = 2(2x+3)
7x - 3x - 3 = 4x + 6
Then what you should do next is combine like terms on the left side, which is 7x & -3x.
So what you would get after combining like terms is:
4x - 3 = 4x + 6
Then what you should do next, is move the 4x from the right side to the left. In order to do that, you must subtract 4x by 4x on the right side, which would cancel it out.
And remember, what you do on one side, you do to the other.
So in the end, you should end up with this:
-3 = 6
Now, due to how there is no more x you are solving for, it would be no solution.

What is Symmetry ?
In common parlance, the term "symmetry" describes a sense of lovely proportion and balance. A more exact meaning of "symmetry" can be found in mathematics, where it typically refers to an object that is unaffected by certain transformations like translation, reflection, rotation, or scaling.
A definition of symmetry in mathematics states that whether one shape is moved, rotated, or flipped, it exactly resembles the other shape. Just fold the paper, draw one-half of the heart at the fold, then cut it out to discover that the other half exactly matches the first half when you are instructed to cut out a "heart" from a piece of paper. The heart-shaped carving is an illustration of symmetry. Symmetry is defined in mathematics as "a mirror image." Symmetry is the property of an image that remains unchanged after a shape has been rotated or flipped. There are patterns in it. You may have heard the word "symmetry" quite a bit in modern times.
(A)
Any two indices will do i!=j Paul's time and the time of the ith runner are equally distributed and independent, hence according to the Symmetry, p (Ai) = p(Aj)= 1/2. Consider the intersection of Ai and Aj. Thus, Paul is outpaced by both runners I and j. There are 6 possible permutations of their times because they are i.id, with Paul being the slowest. P(Ai intersection Aj) hence equals 1/3.
But now wе have that P(Ai intersection Aj)= 1/3 != 1/4 = P(Ai)P(Aj)
thus, events They are not autonomous, Ai and Aj. However, they are only somewhat independent given Paul's timing. Paul can be removed from the narrative if such is the case. Then, only these two runners are left. Events As a result of their independent and equal distribution of times, Aj and AI are independent.
(B)
Define Ij as the random variable indication that indicates whether or not the jth runner is superior to Paul. via means of symmetry. We know p(Ij = 1)=1/2.
We determine that
E(N) = E(I1+I2 +.......In)
= nE(i1)
=nP(I1-1)
=n/2
using the linearity of expectation.
(C)
Paul's estimated time of completion is t The probability that each runner will finish ahead of Paul is P (time of rumer I t) = F. (t)
By using part (a), we can determine that other runners' times are independent of Paull's time, and that the number of runners who finish faster than Paul has a binomial distribution with the parameters n and F. To come to the conclusion that N/T= t Binom (n, F(t)) and if we choose T at random, N/T Binom (n, F(T)),
(D)
Let's figure out Var (N)
Var (N)=F(Var (N/T)) + Var(E(N/T))

according to Eve's Law.
Here, we can use the uniform distribution's universality to produce
F(T) ~Unif (0, 1) = U
Hence symmetry, which states that U I-U, leads to
Var(N) = nE(U2) + n2 var (U)
=n/3 + n2/12,
where E(U2)=1/3

Brayden run a farm tand that ell rapberrie and grape. Yeterday Brayden old 44 pound of rapberrie and 43 pound of grape for a total revenue of $217. Today he old 45 pound of rapberrie and 18 pound of grape for a total revenue of $144. Write a ytem of equation that could be ued to determine the price of each pound of rapberrie and the price of each pound of grape. Define the variable that you ue to write the ytem
The system of the equation that could be used to determine the price of each pound of raspberries and each pound of grape is 44 x + 43 y = 217, 45x + 18y = 144. Each pound of raspberries costs $2 and each pound of grapes costs $3
let x be the price of each pound of raspberries.
and y be the price of each pound of grapes.
Given that he sold 44 pounds of raspberries and 43 pounds of grapes yesterday, bringing in $217 in total revenue
so equation 1 would be 44 x + 43 y = 217
also, he sold 18 pounds of grapes and 45 pounds of raspberries today, earning $144 in total sales.
so equation 2 would be 45x + 18y = 144
Multiplying equation 1 with 18,
792x +774y = 3906
Multiplying equation 2 with 43,
1935x+774y = 6192
on solving
792x +774y = 3906
1935x+774y = 6192
-1143 x=- 2286 (from equation 2)
x = 2286/ 1143
x = 2
putting the value of x in equation 1, to find the value of y
44 x + 43 y = 217
44 (2) + 43 y = 217
43 y = 217 − 88
43 y =129
y = 129/43
y = 3
therefore, the price of each pound of raspberries is $2, and the price of each pound of grapes is $3.

a right circular cylinder, a, has radius r and height h. another right circular cylinder, b, has radius 3r and height 2h. what is the ratio of the volume of a to the volume of b ?
The ratio of the volume of the rigth circular cylinder a to the volume of the right circular cylinder b is 1: 18.
According to the given question.
We have two right circular cylinder, a nd b.
Also,
The radius of right circular cylinder, a is r.
The height of the right circular cylinder, a is h.
The radius of the right circular cylinder, b is 3r.
And the height of the right circular cylinder, b is 2h.
As we know that, the volume of a cylinder can be calculated using the formula V=πr^2(h). Where r is the radius and h is the height of the cylinder.
So, the volume of the right circular cylinder a = πr^2h
And, the volume of the right circular cylinder b = π(3r)^2(2h) = 18hr^2π
Therefore,
The ratio of the volume of the rigth circular cylinder a to the volume of the right circular cylinder b
= πr^2h/18hr^2π
= 1:18
Hence, the ratio of the volume of the rigth circular cylinder a to the volume of the right circular cylinder b is 1: 18.
