The graph at the end of the response provides the dilated figure, which has the same format as the original figure but reduced side lengths as a result of the dilation with a scale factor of less than 1.
What is dilation?To make an opening or hollow structure wider or larger than usual, such as a blood vessel or the pupil of an eye.
The process of dilation entails growing an object's size without changing its shape.
The size of the object may rise or decrease depending on the scale factor.
Using dilation maths, a square with a side of 5 units can be made wider to have a side of 15 units, yet the square retains its original shape.
So, the coordinates of each vertex of the figure are multiplied by the scale factors to create a dilatation in the image.
The vertices for the original figure that was graphed are listed as follows:
I(0,6).
H(3,6).
G(9,0).
F(-6,-9).
E(-6,-6).
The coordinates of the resulting image are presented as follows since the dilation has a scale factor of 1/3, which means that the coordinates are multiplied by 1/3:
I'(0,2).
H'(1,2).
G'(3,0).
F'(-2,-3).
E'(-2,-2).
Therefore, the graph at the end of the response provides the dilated figure, which has the same format as the original figure but reduced side lengths as a result of the dilation with a scale factor of less than 1.

A bakery makes cylindrical mini muffins that measure 2 inches in diameter and one and one fourth inches in height. if each mini muffin is completely wrapped in paper, then at least how much paper is needed to wrap 6 mini muffins? approximate using pi equals 22 over 7.
Answers
The quantity of paper that needed to wrap 6 mini muffins is 84.857 inches^2
The surface area of a cylinder can be calculated using the formula:
Surface Area = 2πr^2 + 2πrh
where r is the radius of the cylinder (which is half of the diameter) and h is the height of the cylinder.
For the mini muffins in question, the diameter is 2 inches, so the radius is 1 inch. The height is 1 and 1/4 inches, or 5/4 inches.
So the surface area of one mini muffin is:
Surface Area = 2π(1)^2 + 2π(1)(5/4)
Surface Area = 2π + 5π/2
Surface Area = 9π/2
To wrap 6 mini muffins, we need to multiply this surface area by 6:
Total Surface Area = 6 x (9π/2)
Total Surface Area = 27π
Approximating π as 22/7, we get:
Total Surface Area ≈ 27 x (22/7)
Total Surface Area ≈ 84.857 inches^2

The exponential function that relates the total population, is [tex]P(t)=540,000\left [ 1+(5.1/100) \right ]^t[/tex] and the rate at which the population is increasing in the year 2019 is 69114.53.
The exponential function in mathematics is represented by the symbol eˣ (where the argument x is written as an exponent). The word, unless specifically stated differently, normally refers to the positive-valued function of a real variable, however it can be extended to the complex numbers or adapted to other mathematical objects like matrices or Lie algebras.

mr. henderson, the principal of blue creek academy, is getting soaked by the splash tank on the last day of school! each time a student hits the target, a 5-quart bucket of water dumps on his head. if 20 students hit the target, how many gallons of water will be dumped on mr. henderson's head?
Answers
25 gallons of water will be dumped on Mr. Henderson's head.
To solve the problem, we first need to find the total amount of water dumped on Mr. Henderson's head by all the students. Since each student dumps a 5-quart bucket of water, we can find the total amount by multiplying the number of students by the amount of water per student:
Total amount of water = 20 students x 5 quarts/student = 100 quarts
Next, we convert the total amount of water from quarts to gallons since the problem asks for the answer in gallons. Since 1 gallon equals 4 quarts, we can divide the total amount of water by 4 to get the answer in gallons:
Total amount of water = 100 quarts ÷ 4 quarts/gallon = 25 gallons.

Answers
The magazine would cost $33.93 to print a 1¾ inch ad in the "Good Ole Times" magazine.
The cost of a classified ad in the "Good Ole Times" magazine is determined by its size in column inches, with a cost of $43.50 per column inch. To determine how much the magazine would charge to print a 1¾ inch ad, we need to calculate the size of ad in column inches and then multiply that by the cost per column inch.
One way to convert 1¾ inches to column inches is to convert the fractional part (¾) to a decimal by dividing it by 4, which is the number of quarters in an inch. This gives us:
1¾ inches = 1 + ¾ inches = 1 + 0.75 inches = 1.75 inches
To express this measurement in column inches, we divide by the width of a column, which is not given in the problem. Assuming a typical newspaper column width of 2.25 inches, we get:
1.75 inches ÷ 2.25 inches per column = 0.7778 column inches
Rounding this to two decimal places, we get:
0.78 column inches
Now we can calculate the cost of the ad as follows:
Cost = Size in column inches × Cost per column inch
Cost = 0.78 column inches × $43.50 per column inch
Cost = $33.93
Therefore, the magazine would charge $33.93 to print a 1¾ inch ad.

if you select a single marble out of the bag, what is the probability that it is a color other than white or blue? express your answer as a fraction in lowest terms or a decimal rounded to the nearest millionth.
Answers
The above table represents the contents ( colored marble) of a bag. The probability that selected marble had a color other than white or blue is equals to the 0.766234 ( nearest to milinoth).
We have a bag that contains five different types of marbles. See the above table
number of red marbles in a bag = 16
number of green marbles in a bag = 23
number of blue marbles in a bag = 13
number of pink marbles in a bag = 20
number of white marbles in a bag = 5
So, total number of marbles in a bag= 16 + 23 + 5 + 13 + 20 = 77
Now, a single marble is selected and out of the bag. We have to determine probability that it is a color other than white or blue. Let X , Y and Z be three events defined as the following
X = selected marble is white
Y = selected marble is blue
Z = selected marble is other than blue or white
Probability of seclecting white marble, P(X) = 5/77
Probability of seclecting blue marble, P(Y)
= 13/77
Probability of seclecting blue or white marble, P(Y UX) = P(X) + P(Y) = 5/77 + 13/77 = 18/77
So, probability that selected marble has a color other than white or blue, P(Z) = 1 - P( X UY) = 1 - 18/77
= 59/77 = 0.76623376623
Hence, required probability is 0.766234.

25 percent * 71

Percentage solution with steps:
Step 1: Our output value is 71.Step 2: We represent the unknown value with x.Step 3: From step 1 above, 71 = 100%.Step 4: Similarly, x = 25%.Step 5: This results in a pair of simple equations:71 = 100% (1)
X = 25% (2)
Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of bothequations have the same unit (%); we have

if the company sells the jelly beans in packs of 9 bags, what can we say about the likelihood that the average weight of the bags in a randomly selected pack is 2 or more grams lighter than advertised?
Answers
There is a 2.28% likelihood that the average weight of the bags in a randomly selected pack is 2 or more grams lighter than advertised.
Assume that the advertised weight is equivalent to the typical weight of one bag, which is 30 grammes. A pack of nine bags would therefore weigh 9 x 30 = 270 grammes.
Let's now assume that each bag actually weighs 30 grammes on average, with a 2 gramme standard deviation, according to a normal distribution (which represents the variability in the weight of the bags).
We need to apply the central limit theorem to determine the probability that the average weight of the bags in a randomly selected pack is 2 or more grammes less than stated. According to this theorem, the mean of a sufficiently large sample (in this case, nine bags) will have a sampling distribution that is roughly normal, with a mean of 30 grammes and a standard deviation of 2 grammes divided by the square root of the sample size (9 = 0.67 grammes). The mean will also be equal to the population's standard deviation.
We can determine the likelihood that the sample mean of a pack of 9 bags weighs less than 28 grammes using a normal distribution table or calculator (which is 2 grammes less than the advertised weight of 30 grams). This likelihood is roughly 0.0228, or 2.28%.

What is dilation?In Geometry, dilation can be defined as a type of transformation which typically changes the size of a geometric shape, but not its shape. This ultimately implies that, the size of the geometric shape would be increased (enlarged) or decreased (reduced) based on the scale factor applied.
In this exercise, we would use an online graphing calculator to plot the image of ABC after a dilation by a scale factor of 1/3 centered at P.
Based on the image (see attachment), we can logically deduce that each vertex is 1/3 times as far from center P as the original vertex and each segment is 1/3 times as long as the original:
Side length AC = 6.7/3 = 2.2

In order to write an absolute value equation in the form |x-c|=d to satisfy a given solution set on a number line, you need to do the following:First, identify the number c, which is the midpoint of the solution set. This is because the absolute value of x-c is equal to the distance between x and c on the number line.
Next, identify the number d, which is equal to the distance between the midpoint c and one of the endpoints of the solution set. This is because the absolute value of x-c can never be greater than the distance between x and c, so the maximum value of x that satisfies the equation is c+d and the minimum value is c-d.Finally, write the equation in the form |x-c|=d using the values of c and d that you identified.

Based on the confidence interval alone, we cannot come to the conclusion that 90% of households have a number of children between .7 and 2.1. A confidence interval only provides a range of values that likely contains the true population parameter (in this case, the average number of children per household) with a certain level of confidence (in this case, 90%).

Answers
As per the given percentage, the total number of beings surveyed is 75.
We are given that 96% of all beings on earth prefer orange juice. This means that if we take a random sample of beings from earth, 96% of them would prefer orange juice. Mathematically, we can express this as:
Percentage of beings who prefer orange juice = 96%
We are also given that 72 people preferred orange juice. We can use this information to find the total number of beings surveyed. Let's assume that the total number of beings surveyed is "x".
Now, we know that 96% of these beings prefer orange juice. We can express this as:
96% of x = 72
To solve for "x", we need to get rid of the percentage sign. We can do this by converting the percentage to a decimal. To convert a percentage to a decimal, we divide it by 100.
So, 96% can be expressed as 0.96 (96/100). Therefore, we can rewrite the above equation as:
0.96x = 72
To solve for "x", we can divide both sides of the equation by 0.96:

alicia had $22 to spend on pencils if each pencil cost $1.50 how many pencils can she buy? What is the Inequality or Equation
Answers
If each pencil cost $1.50 and Alicia had $22 to spend on them, she could purchase 14 pencils. This situation's inequality is as follows: 1.5x ≤ 22.
To find out how many pencils Alicia can buy, we can divide her total budget by the cost per pencil:
Number of pencils = Total budget / Cost per pencil
Number of pencils = $22 / $1.50
Number of pencils = 14.67 (rounded to two decimal places)
Alicia cannot buy a fraction of a pencil, so she can buy a maximum of 14 pencils.
The inequality that represents this situation is:
1.5x ≤ 22
Where x represents the number of pencils Alicia can buy. We divide both sides of the inequality by 1.5 to isolate x:
x ≤ 14.67
Since Alicia cannot buy a fraction of a pencil, we round down to the nearest whole number and get:
x ≤ 14
So, Alicia can buy a maximum of 14 pencils.

the average on a standardized test of educational achievement is 600, and the standard deviation is 50. what is the percentage of the area between 550 and 725?
Answers
37.5% of the area between 550 and 725 on a standardized test of educational achievement lies within one standard deviation of the mean score of 600.
The area between 550 and 725 on a standardized test of educational achievement is equal to the percentage of students whose scores fall within one standard deviation (or 68%) of the mean score of 600. This can be expressed mathematically as:
Percentage = (725 - 550) / (2 * 50) = 37.5 / 100 = 37.5%
To explain in more detail, a standard deviation is a measure of the spread of a dataset around its mean value. The mean value in this case is 600, and the standard deviation is 50. Therefore, one standard deviation from the mean is calculated by subtracting or adding the standard deviation (50) from the mean (600), giving a range of 550 to 650.
Since the area in question spans across two standard deviations (550 to 725), the area is calculated by subtracting the lower range (550) from the upper range (725) and then dividing it by two standard deviations (100). This gives us the area, which is 37.5%.
To summarize, 37.5% of the area between 550 and 725 on a standardized test of educational achievement lies within one standard deviation of the mean score of 600.

10 1/4 divided by 5 1/2?
Answers
Answer:
To divide two mixed numbers, we need to first convert them to improper fractions.
10 1/4 is the same as (10 x 4 + 1)/4 = 41/4
5 1/2 is the same as (5 x 2 + 1)/2 = 11/2
So, we need to divide 41/4 by 11/2:
(41/4) ÷ (11/2)
When dividing by a fraction, we can multiply by its reciprocal (flip the fraction):
(41/4) x (2/11)
Now, we can simplify by canceling out the common factors:
(41 x 2) / (4 x 11) = 82/44 = 41/22
Therefore, 10 1/4 divided by 5 1/2 is equal to 41/22 or approximately 1.86 when rounded to two decimal places.
Por lo tanto, 10 1/4 dividido por 5 1/2 es igual a 41/22 o aproximadamente 1,86 cuando se redondea a dos decimales.
Use the given scale factor and the side lengths of the scale drawing to determine the side lengths of the real objects.
Answers
Using the scale factor of 4:1, the side lengths of the real objects are:
B. Side a is 5 inches long and side b is 4.5 inches long.
What is a Scale Factor?A scale factor is a number that represents the ratio of the size or dimensions of an object in relation to another object. It is a proportional relationship between two similar objects, where the scale factor is the ratio of any corresponding lengths or dimensions.
Thus, given that the scale factor is 4:1, it means 4 inches of the scale drawing represents 1 inch of the real object.
Therefore, the sides would be:
Side a = 20/4 = 5 in.
Side b = 18/4 = 4.5 in
The answer is B.

describe the technique used to count the rational numbers (1-1 correspondence with the natural number
Answers
Yet because we can compare the set of positive rational numbers exactly to the collection of natural numerals, we may infer that the set of positive rational must have a number of clusters of 0, or n(Q+)=0. Due to the fact that these two numbers must equal one another, 02 = 0.
Since they may be arranged in a one-to-one correspondence with the natural numbers (the integers, such as 1, 2, and 3), Cantor showed in 1873 that the rational numbers, although being infinite, are countable (or denumerable).
How are the rational numbers counted as a group?
To achieve this, we take into account the this double integers grid upon that positive orthogonal. If p and q are positive natural numbers, then p/q may be used to represent any positive valid value.
Simply put, we establish the following values: h(0) = 0, h(2n) = f(n), for all natural numbers n > 0, and h(2n-1) = g(n) = -f(n), for all natural numbers n > 0.
