The relative frequency of respondents for a sample of 313 people who identified as Democrat, Republican, or Independent can be calculated by dividing the number of respondents for each group by the total number of respondents (313).
For example, if 100 respondents identified as Democrat, the relative frequency of Democrats would be 100/313, or approximately 32%. If 125 respondents identified as Republican, the relative frequency of Republicans would be 125/313, or approximately 40%. If the remaining 88 respondents identified as Independent, the relative frequency of Independents would be 88/313, or approximately 28%.
Therefore, the relative frequency of respondents in the sample of 313 people would be 32% Democrat, 40% Republican, and 28% Independent.

hillary took a photograph of her house, which has an actual height of 28.5 feet. if the house measures 3.6 inches tall in the photograph, what is the scale factor?
The scale factor of Hillary's photograph of her house is 1:8. This means that for every 1 inch of the house that is shown in the photograph, the house is actually 8 inches tall in real life.
To calculate the scale factor, you need to divide the actual height of the house by the height shown in the photograph. 28.5 feet divided by 3.6 inches gives a result of 8. In other words, for every 1 inch of the house that is shown in the photograph, the house is actually 8 inches tall in real life.
To explain further, the scale factor is a ratio that is used to compare two different measurements of the same object or shape. It tells us how much bigger or smaller one measurement is compared to another. In this case, we have compared the actual height of the house (28.5 feet) to the height of the house as shown in the photograph (3.6 inches). The ratio of the two measurements (1:8) tells us that the house is 8 times bigger in real life than it appears in the photograph.
The scale factor is an important concept in the field of mathematics and is often used in science, engineering, and architecture. It is used to measure the size and shape of objects, as well as to convert measurements from one unit of measure to another.
Therefore, the scale factor of Hillary's photograph of her house is 1:8, meaning that for every 1 inch of the house that is shown in the photograph, the house is actually 8 inches tall in real life.

Números que multiplicados me den 24 y sumados me den -11
The two numbers that multiply to give 24 and add to give -11 are -3 and -8.
How do we get these numbers?To find these numbers, you can use a system of equations. Let x and y be the two numbers. Then we have:
xy = 24 (because the two numbers multiply to give 24)x + y = -11 (because the two numbers add to give -11)We can use the second equation to solve for one of the variables in terms of the other. For example, we can solve for x:
x + y = -11
x = -11 - y
We can then substitute this expression for x into the first equation:
xy = 24
(-11 - y)y = 24
Expanding and rearranging, we get:
y^2 + 11y + 24 = 0
This is a quadratic equation that we can solve using factoring or the quadratic formula. Factoring, we get:
(y + 3)(y + 8) = 0
So either y + 3 = 0 or y + 8 = 0. This means that y can be -3 or -8. Substituting each of these values into x = -11 - y, we get:
If y is -3, then x is -11 - (-3) = -8
If y is -8, then x is -11 - (-8) = -3.

James deposited 10000 into an account that earns 5.5% compound interest, compounded semiannually. How much interest will James earn after 10 years?
James will earn approximately $6,639.12 in interest after 10 years.
What is simple interest?
Simple Interest (S.I.) is the method of calculating the interest amount for a particular principal amount of money at some rate of interest.
To solve this problem, we can use the formula for compound interest:
[tex]A = P(1 + r/n)^{(nt)}[/tex]
where:
A is the final amount (including interest)
P is the principal amount (initial deposit)
r is the annual interest rate (as a decimal)
n is the number of times the interest is compounded per year
t is the time (in years)
Plugging in the given values, we get:
[tex]A = 10000(1 + 0.055/2)^{(2*10)}[/tex]
[tex]A = 10000(1.0275)^{20}[/tex]
A = 10000(1.664)
A ≈ 16639.12
To find the amount of interest earned, we subtract the principal amount from the final amount:
Interest = A - P
Interest = 16639.12 - 10000
Interest ≈ 6639.12
Therefore, James will earn approximately $6,639.12 in interest after 10 years.

which postulate or property can be used to prove that kimball is not between scottsbluff and sidney?
The postulate or property that can be used to prove that Kimball is not between Scottsbluff and Sidney is the Segment Addition Postulate.
The Segment Addition Postulate states that for three points A, B, and C, where B is between A and C,
we have AB + BC = AC.
Given that Kimball is not between Scottsbluff and Sidney, this means that Kimball is either to the west of Scottsbluff or to the east of Sidney.
Let's assume that Kimball is to the west of Scottsbluff.
Then, we can draw the line segment as follows:
Scottsbluff ——————— Kimball ——————— Sidney
Let AB represent the distance between Scottsbluff and Kimball, and let BC represent the distance between Kimball and Sidney. According to the Segment Addition Postulate, AB + BC = AC, where AC is the distance between Scottsbluff and Sidney.
However, if we draw the line segment from Scottsbluff to Sidney without Kimball, we can see that the distance between the two points will always be shorter than the sum of the distances from Scottsbluff to Kimball and from Kimball to Sidney.
This implies that if Kimball is not between Scottsbluff and Sidney, then it is not possible for the segment addition postulate to hold true for the three points.
Therefore, we can use the segment addition postulate to prove that Kimball is not between Scottsbluff and Sidney.

a(n) ? is a device that indicates whether two ac sources to be connected in parallel are in the correct phase relationship.
The device that indicates whether two AC sources to be connected in parallel are in the correct phase relationship is called a synchronizing device.
A synchronizing device is a mechanism that ensures that two AC sources are in sync when they are connected in parallel. It's used to match the voltage, frequency, and phase angle of two alternating current (AC) sources.
It guarantees that the power supplied by both generators is synchronized, allowing them to be combined into a single electrical system without disrupting the balance of the current or causing a short circuit.
As a result, it is critical to the safe and efficient operation of power systems. A phase sequence indicator (PSI) or a synchroscope is often used as a synchronizing device. It works by providing an indication of the voltage difference, the phase angle difference, and the frequency difference between two AC sources that are to be synchronized.
Therefore, a synchronizing device is an instrument that determines whether two alternating current (AC) sources to be connected in parallel are in the appropriate phase relationship.

mathematically.
5. The sanctuary currently has 125 exotic fish. The average amount of the tank allotted for each fish is represented by the binomial (22 − 1). Are the dimensions of the new habitat adequate
for these 125 fish? Explain.
To ensure that the dimensions of the fish tank are adequate, we need to ensure that the volume of the fish tank is greater than or equal to 2625. Since we do not have any information about the dimensions of the fish tank,
What ensures dimensions of the fish tank are adequate?1. Let the dimensions of the fish tank be length, width, and height, represented by l, w, and h, respectively. V = l^1 × w^1 × h^1 = lwh. Therefore, the polynomial that represents the volume of the fish tank is V = lwh.
2. Then the volume of each hemisphere is (4/3)πr^3. Since there are two hemispheres, the total volume they take up is 2(4/3)πr^3 = (8/3)πr^3.
Therefore, the new volume of the fish tank after the hemispheres are installed is V - (8/3)πr^3, where V is the original volume of the fish tank. Substituting V = lwh, we get:
[tex]V_new = lwh - (8/3)πr^3[/tex]
3.The binomial that represents the length of the fish tank is l. To show that it is a factor of the polynomial V = lwh, we need to show that V is divisible by l, which means there exists a polynomial q such that V = lq. We can see that:
[tex]V = lwh = l(wh) = l(q)[/tex], where q = wh.
Therefore, l is a factor of V.
4. To determine if the binomial l is a factor of the polynomial V_new = lwh - (8/3)πr^3, we need to check if V_new is divisible by l. We can use polynomial long division to divide V_new by l:
Let the dimensions of the fish tank be length, width, and height, represented by l, w, and h, respectively.
Then the volume of the fish tank is V = lwh. We can use the properties of exponents to simplify this expression by multiplying the powers of the variables: [tex]V = l^1 × w^1 × h^1 = lwh[/tex] . Therefore, the polynomial that represents the volume of the fish tank is V = lwh.
The volume of each hemisphere is [tex](4/3)πr^3[/tex] . Since there are two hemispheres, the total volume they take up is [tex]2(4/3)πr^3 = (8/3)πr^3.[/tex]
Therefore, the new volume of the fish tank after the hemispheres are installed is V - (8/3)πr^3, where V is the original volume of the fish tank. Substituting V = lwh, we get:
V_new = l [tex]wh - (8/3)πr^3[/tex]
The binomial that represents the length of the fish tank is l. To show that it is a factor of the polynomial V = lwh, we need to show that V is divisible by l, which means there exists a polynomial q such that V = lq. We can see that:
V = lwh = l(wh) = l(q), where q = wh.
Therefore, l is a factor of V.
To determine if the binomial l is a factor of the polynomial V_new = lwh - (8/3)πr^3, we need to check if V_new is divisible by l. We can use polynomial long division to divide V_new by l:
Since there is a remainder of [tex]- (8/3)πr^3[/tex] , we can see that l is not a factor of V_new.
5. The average amount of tank allotted for each fish is represented by the binomial [tex](22 − 1)[/tex] . To determine if the dimensions of the new habitat are adequate for 125 fish, we need to check if the volume of the fish tank is greater than or equal to the space required for 125 fish.
Let the required space for each fish be v, then the total space required for [tex]125[/tex] fish is [tex]125v[/tex] . Substituting the given binomial, we have:
[tex]v = (22 - 1) = 21[/tex]
Therefore, the total space required for 125 fish is [tex]125v = 125(21) = 2625[/tex] . We cannot determine if it is adequate for the given number of fish.

(2,90) and (4,810) as an exponential function
Answer:
y = 10(3)^x
Step-by-step explanation:
The general form of an exponential function is
[tex]y=ab^x[/tex], where x and y are any coordinate in the exponential function, a is the initial value, and b is the base.
Currently, we only have xs and ys, which forces us to find a and b:
[tex]90=ab^2\\810=ab^4[/tex]
We can find b first by dividing the larger x and y (4, 810) by the smaller x and y (2, 90). Thus, we must plug the xs and ys in and create a fraction:
[tex]\frac{810}{90}=\frac{ab^4}{ab^2}[/tex]
We know that a represents a value a number divided by itself is 1 and that 810/90 = 9 so we now have:
[tex]9=\frac{b^4}{b^2}[/tex]
According to quotient rule of exponents, when you divide bases with exponents, you subtract the exponent on the numerator from the base on the denominator:
[tex]9=b^4^-^2\\9=b^2\\3=b[/tex]
Now we can simply plug in our first coordinate and 3 for b to find a:
[tex]90=a(3)^2\\90=9a\\10=a[/tex]
Thus, the equation of the exponential function which contains the points (2,90) and (4,810) is
y = 10(3)^x

Shaina made a container of lemonades and her brother drank 1/4 of it. Her father then drank 2/3 of the remaining 3/4, which is equivalent to drinking 1/2 of the container.
Shaina made a container of lemonades and her brother drank 1/4 of it, leaving 3/4 in the container. Her father then drank 2/3 of the remaining 3/4, which is equivalent to drinking 2/3 x 3/4 = 6/12 = 1/2 of the container. In other words, her father drank 1/2 of the container.
We can also solve this problem using algebra. Let 'x' represent the total amount of lemonade in the container. Then, her brother drank 1/4x, leaving 3/4x in the container. Her father then drank 2/3 of the remaining lemonade, which is equal to 2/3 x (3/4 x) = 6/12 x = 1/2x. Since her father drank 1/2x of the container, we can conclude that x = 1/2x, which means that x = 2/2x = 1. Therefore, the total amount of lemonade in the container was 1 and her father drank 1/2 of it.
To summarize, Shaina made a container of lemonades and her brother drank 1/4 of it. Her father then drank 2/3 of the remaining 3/4, which is equivalent to drinking 1/2 of the container.

a pizza that is 12 in diameter is cut into six slices. find the length of each arc intercepted by each slice (length of the crust). find the area of each slice.
The length of each arc intercepted by each slice is 2.09 inches.
The area of each slice 18.85 square inches .
To find the length of each arc intercepted by each slice and the area of each slice of a pizza that is 12 inches in diameter, follow the steps below. Length of each arc intercepted by each slice
The formula to find the length of each arc is given by:
L = θ/360 * 2πr
WhereL = length of arc
θ = angle of arc in degrees
r = radius of circle (diameter/2)
Given, diameter of pizza = 12 inches
So, radius of pizza = 12/2 = 6 inches
Since the pizza is cut into 6 equal slices, each slice will have an angle of 360/6 = 60 degrees.
Now, substituting the given values in the formula:
L = 60/360 * 2π* 6L = 1/6 * 12πL = 2π/3 ≈ 2.09 inches
The formula to find the area of each slice is given by:
A = θ/360 * πr²
Given, diameter of pizza = 12 inches
So, radius of pizza = 12/2 = 6 inches
Since the pizza is cut into 6 equal slices, each slice will have an angle of 360/6 = 60 degrees.
Now, substituting the given values in the formula:
A = 60/360 * π* 6²A = 1/6 * 36π
A = 6π ≈ 18.85 square inches
Thus, the length of each arc intercepted by each slice is approximately 2.09 inches and the area of each slice is approximately 18.85 square inches.

To determine the population of bacteria after 15 days, we simply substitute x = 15 into the equation:
y = 12,000 * (2¹⁵)
y = 12,000 * 32
y = 384,000
Therefore, the population of bacteria after 15 days is 384,000.

Find the average rate of change for the function
Answer:
average rate of change on [-1,3] = 11
Step-by-step explanation:
avg rate of change = [tex]\frac{f(b)-f(a)}{b-a}[/tex]
[tex]\frac{f(3)-f(-1)}{3-(-1)}[/tex]
1. find your y-values.
we are given the x values from the interval [-1,3]. Plug each into the equation to get the y-value of the coordinates.
[tex]f(-1)=4(-1)^2+3(-1)-4\\f(-1)=4(1)-3-4\\f(-1)=-3\\[/tex]
coordinate: (–1,3)
[tex]f(3)=4(3)^2+3(3)-4\\f(3)=4(9)+9-4\\f(3)=36+9-4\\f(3)=41[/tex]
coordinate: (3, 41)
2. plug into the slope formula
[tex]m=\frac{y_{2} -y_{1} }{x_{2} -x_{1} } \\m=\frac{41-(-3)}{3-(-1)} \\m=\frac{41+3}{4} \\m=\frac{44}{4} \\m=11[/tex]
Given f(x) = x^2+ x + 1 and g(x) = x^2 - 9. find: (f + g) (x)
Answer: [tex]2x^{2} +x-8[/tex]
Step-by-step explanation:
(f + g)(x)
= f(x) + g(x)
= [tex]x^{2} +x+1+(x^{2} -9)[/tex]
= [tex]x^{2} +x+1+x^{2}-9[/tex]
= [tex]2x^{2} +x-8[/tex]
if the matrix product a1b is known, how could you calculate b1a without necessarily knowing what a and b are?
We can calculate its product by taking the dot product of each row of B1A and each column of A1B. In this way, we can calculate B1A without knowing the values of A and B.
The matrix product of two matrices, A and B, is defined as the matrix C, where C = AB. To calculate the product of two matrices, we must take the dot product of each row of A and each column of B. If we are given a matrix product A1B, then we can calculate B1A without necessarily knowing what A and B are.
To do so, we must first invert the matrix A1B. We can do this by solving a system of equations. We can set up this system of equations by treating the entries of A1B as the coefficients in a system of equations, and solving for the entries of B1A. Once we have found the inverse, we can calculate the matrix B1A.
Finally, once we have the matrix B1A, we can calculate its product by taking the dot product of each row of B1A and each column of A1B. In this way, we can calculate B1A without knowing the values of A and B.

If there are 55 children in a five a side field how many children are on each team
There are 55 children in total, and each team will have 27 children.
Now, you mentioned that there are 55 children in total. To find out how many children are on each team, we need to divide the total number of children by the number of teams. In this case, there are two teams, so we divide 55 by 2.
When we divide 55 by 2, we get 27.5. However, we cannot have half a child on a team, so we need to round the number to the nearest whole number. In this case, the median can be used to determine the most appropriate rounding.
The median is the middle value of a set of numbers. In this case, if we arrange the numbers 1, 2, 3, ..., 55 in ascending order, the median will be the 28th number.
Now, we have two options for rounding. We can either round up to 28 or round down to 27. Since we cannot have a partial player, we must decide which option is most appropriate.
In this case, it's best to have an equal number of players on each team. Therefore, we'll round down to 27. This means that each team will have 27 children.
