The distribution of heights of young women is approximately Normal with mean 64 inches and standard deviation 2.7 Use the 68-95-99.7 rule to answer the questions.
Therefore, the height range that encompasses 99.7% of adolescent women is roughly between 55.9 and 68.1 inches.
What can you infer from standard deviation?It reveals the average deviation of each number from the norm. When it comes to normally distributed, a large standard deviation denotes that values are typically out of the mean, whereas a smaller standard deviation denotes that values are grouped closely around the mean.
The 68-95-99.7 rule is a way to remember the percentage of data that falls within certain numbers of standard deviations from the mean in a normal distribution. Specifically:
About 68% of the data falls within 1 standard deviation of the meanAbout 95% of the data falls within 2 standard deviations of the meanAbout 99.7% of the data falls within 3 standard deviations of the meanUsing this rule, we can answer the following questions:
What is the range of heights that includes about 68% of young women?About 68% of young women have heights within 1 standard deviation of the mean. Therefore, we can find the range of heights that includes this percentage by adding and subtracting 1 standard deviation from the mean:
64 inches ± 2.7 inches
So the range of heights that includes about 68% of young women is approximately 61.3 inches to 66.7 inches.
2. What is the range of heights that includes about 95% of young women?
About 95% of young women have heights within 2 standard deviations of the mean. Therefore, we can find the range of heights that includes this percentage by adding and subtracting 2 standard deviations from the mean:
64 inches ± 2(2.7 inches)
So the range of heights that includes about 95% of young women is approximately 58.6 inches to 69.4 inches.
3. What is the range of heights that includes about 99.7% of young women?
About 99.7% of young women have heights within 3 standard deviations of the mean. Therefore, we can find the range of heights that includes this percentage by adding and subtracting 3 standard deviations from the mean:
64 inches ± 3(2.7 inches)
So the range of heights that includes about 99.7% of young women is approximately 55.9 inches to 68.1 inches.

learner sell 300 vetkoet every week for 12 they charge 10 for each vetkoet calculate the profit they will if the cost for each vetkoet is 3.80
The profit for selling 300 vetkoek every week at a cost of 3.80 per vetkoek and selling them for 10 each is 1860.
What is Algebraic expression ?
Algebraic expression can be defined as combination of variables and constants.
To calculate the profit for selling 300 vetkoek every week, we need to first calculate the total revenue generated and the total cost of producing the vetkoek.
Total revenue = Price per vetkoek x Number of vetkoek sold
Total revenue = 10 x 300 = 3000
Total cost = Cost per vetkoek x Number of vetkoek sold
Total cost = 3.80 x 300 = 1140
Profit = Total revenue - Total cost
Profit = 3000 - 1140 = 1860
Therefore, the profit for selling 300 vetkoek every week at a cost of 3.80 per vetkoek and selling them for 10 each is 1860.

As seen in the diagram below, Austin is building a walkway with a width of xx feet to go around a swimming pool that measures 8 feet by 10 feet. If the total area of the pool and the walkway will be 360 square feet, how wide should the walkway be?
Answer:
We can start the problem by using the formula for the area of a rectangle:
Area = length x width
The total area of the pool and the walkway is given as 360 square feet. Let's assume that the width of the walkway is w feet. Then, the dimensions of the entire area can be represented as (8 + 2w) by (10 + 2w) feet, since there is an additional width of w feet on both sides of the pool. Therefore, we can set up the equation:
(8 + 2w) x (10 + 2w) = 360
Expanding the left side and simplifying, we get:
4w^2 + 36w - 80 = 0
We can solve for w using the quadratic formula:
w = (-b ± sqrt(b^2 - 4ac)) / 2a
In this case, a = 4, b = 36, and c = -80. Substituting these values into the formula, we get:
w = (-36 ± sqrt(36^2 - 4(4)(-80))) / 8
w = (-36 ± sqrt(1872)) / 8
w ≈ -5.6 or w ≈ 3.6
Since the width cannot be negative, we can discard the first solution. Therefore, the width of the walkway should be approximately 3.6 feet.

Determine which of the four levels of measurement (nominal, ordinal, interval, ratio) is most appropriate for the data below.
Course grades from A to F
Question content area bottom
Part 1
Choose the correct answer below.
A.
The ratio level of measurement is most appropriate because the data can be ordered, differences (obtained by subtraction) can be found and are meaningful, and there is a natural starting point.
B.
The ordinal level of measurement is most appropriate because the data can be ordered, but differences cannot be found or are meaningless.
C.
The nominal level of measurement is most appropriate because the data cannot be ordered.
D.
The interval level of measurement is most appropriate because the data can be ordered, differences obtained by subtraction can be found and are meaningful and there is no natural staring point 
Option (B): The ordinal level of measurement is most appropriate because the data can be ordered, but differences cannot be found or are meaningless.
What are the levels of measurement?
You may find out how accurately variables are recorded using levels of measurement, also known as scales of measurement. A variable in scientific research is anything that can have several values depending on the data collection.
Four levels of measuring exist:
Nominal: The information is only classifiable.Ordinal: The information is classifiable and rankableInterval: Data can be categorised, rated, and spaced evenly.Ratio: The data is equally distributed, categorised, ranked, and has a natural zero.You might only be able to perform a limited amount of data analysis depending on the level of measurement of the variable. From low (nominal) to high, there is a hierarchy in the complexity and precision of the level of measurement (ratio).
We have to find the appropriate level of measurement for the data course grades from A to F.
Here there is an order for ranking. This is because A is the highest grade followed by B, C, D, E and F respectively.
So nominal level of measurement is out of the question.
Now, there are no numerical values associated with the grades. We have no means to find the difference between the two grades.
Therefore the most appropriate level of measurement for Course grades from A to F is,
Option (B): The ordinal level of measurement is most appropriate because the data can be ordered, but differences cannot be found or are meaningless.

There are 270 students at Colfax Middle School, where the ratio of boys to girls is 5 : 4. There are 180 students at Winthrop Middle School, where the ratio of boys to girls is 4: 5. The two schools hold a dance and all students from both schools attend. What fraction of the students at the dance are girls?
We have the following response after answering the given question: equation Hence, there are 22/45 female students at the dance.
What is equation?In a mathematical equation, the equals sign (=), which connects two claims and denotes equality, is utilised. In algebra, an equation is a mathematical statement that proves the equality of two mathematical expressions. For instance, in the equation 3x + 5 = 14, the equal sign separates the numbers by a space. Mathematical expressions can be used to describe the relationship between the two sentences on either side of a letter. The logo and the particular piece of software frequently correspond. like, for instance, 2x - 4 = 2.
Now, let's determine how many boys and females attend each school:
Middle School in Colfax
Boys: (5/9) * 270 = 150
Girls: (4/9) * 270 = 120
School in Winthrop:
Boys: (4/9) * 180 = 80
Girls: (5/9) * 180 = 100
Now, we can determine how many males and girls attended the dance overall:
Boys: 150 + 80 = 230
Girls: 120 + 100 = 220
Thus, the proportion of female students attending the dance is:
220 / (230 + 220) = 220 / 450 = 44/90 = 22/45
Hence, there are 22/45 female students at the dance.

Sheri's deck design is shown below. Which shape has the same perimeter but a different area than Sheri's design?
The shape that has the same perimeter but a different area than Sheri's design is option D.
What is perimeter?
The complete length of a shape's boundary is referred to as the perimeter in geometry. A shape's perimeter is calculated by adding the lengths of all of its sides and edges. Its dimensions are expressed in linear units like centimetres, metres, inches, and feet.
The figure contains sides with the measurements, 2 units, 4 units, 4 units, 2 units, 2 units, and 2 units.
The perimeter of the figure will be sum of all sides -
Perimeter = 2 + 4 + 4 + 2 + 2 + 2
Perimeter = 16 units
Therefore, the figure has perimeter of 16 units.
The area of the figure can be determined by adding the area of rectangle and square.
Side of the square measures 2 units.
The length of the rectangle is 2 units.
The breadth of the rectangle is 4 units.
So, the equation will be -
Area = Area of rectangle + Area of square
Area = (l × b) + (side)²
Area = (2 × 4) + (2)²
Area = 8 + 4
Area = 12 units²
Therefore, the figure has area of 12 units².
The diagram in option D contains sides with the measurements, 3 units, 1 unit, 1 unit, 3 units, 4 units, and 4 units.
The perimeter of the figure will be sum of all sides -
Perimeter = 3 + 1 + 1 + 3 + 4 + 4
Perimeter = 16 units
Therefore, the figure has perimeter of 16 units.
The area of the figure can be determined by adding the area of the two rectangles.
The length of the first rectangle is 1 unit.
The breadth of the first rectangle is 3 units.
The length of the second rectangle is 3 units.
The breadth of the second rectangle is 4 units.
So, the equation will be -
Area = Area of rectangle 1 + Area of rectangle 2
Area = (l × b) + (l × b)
Area = (1 × 3) + (3 × 4)
Area = 3 + 12
Area = 15 units²
Therefore, the figure has area of 12 units².

There is something that looks like a backwards y. If the "backwards y" (∠2)=98°, find the following angle measures.
Angles 1 = 2 = 3 = 98° and 4 = 82° are measured.
What angles are appropriate?The right angle is created when two straight lines cross at a 90° angle or when they are perpendicular at the intersection. The image serves as a right angle indicator. The angle formed when two chords cross paths inside of a circle is equal to half the sum of the chords' intercepted arcs. Hence, m1 = 50° and m2 = 130°.
The other angle measurements can be calculated using the diagram as follows:
∠1: ∠1 is a vertical angle to ∠2, so it is also 98°.
∠3: ∠3 is a corresponding angle to ∠2, so it is also 98°.
∠4: ∠4 and ∠2 form a straight angle, which means they add up to 180°. Therefore, ∠4 = 180° - ∠2 = 180° - 98° = 82°.
So, the angle measures are:

What is mean by Function?A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
Given that;
The function is,
g (x) = 2x² - 8
Now, We have;
For x ≥ 0;
The inverse function is,
⇒ f (x) = √1/2x + 4
And, For x ≤ 0;
The inverse function is,
⇒ d (x) = - √1/2x + 4
Hence, For x = - 8;
⇒ d (x) = - √1/2x + 4
⇒ q = - √1/2 × - 8 + 4
⇒ q = - √- 4 + 4
⇒ q = 0
For x = 0;
⇒ f (x) = √1/2x + 4
⇒ r = √1/2 × 0 + 4
⇒ r = √0 + 4
⇒ r = 2
For x = 10;
⇒ d (x) = - √1/2x + 4
⇒ t = - √1/2 × 10 + 4
⇒ t = - √5 + 4
⇒ t = - 3
For x = 10;
⇒ f (x) = √1/2x + 4
⇒ s = √1/2 × 10 + 4
⇒ s = √5 + 4
⇒ s = 3
Thus, The value of variables are,
q = 0
r = 2
s = - 3
t = 3

Solve this system of equations for x using the addition method. (Must show steps of addition method to get credit. Do not solve using the substitution method.)
The solution for the inequality expression given is x > -2.154.
What is Linear Inequalities?Linear inequalities are defined as those expressions which are connected by inequality signs like >, <, ≤, ≥ and ≠ and the value of the exponent of the variable is 1.
Given linear inequality is,
-5/7 (21x + 35) < 1/3 (9 - 6x)
We have to solve the inequality.
Using the distributive property,
(-5/7 × 21x) + (-5/7 × 35) < (1/3 × 9) - (1/3 × 6x)
-15x - 25 < 3 - 2x
-15x + 2x < 3 + 25
-13x < 28
-x < 2.154
Multiplying throughout by negative 1.
x > -2.154
Hence the solution is x > -2.154.

Graph the following feature
Y intercept =2
Slope = -6/5
your given information is important because your first piece of info is the y intercept. The y intercept can be interpreted as (0,2). this is your initial point.
once you have that point, you can then use the slope to finish off your linear function. the slope is rise/run.
this means that you have to travel in the y direction, which is your rise. this means you have to go either in the positive or negative, depending on the number. in this case, it's -6, so we would go down 6.
then we would run 5 units in the x direction and same like the x it would be depending on the number being positive or negative. since we have a +5 it means we have to move 5 units to the right should have a graph that looks like a (\).
hope it helps.

The population of Mexico between 1921 and 2010 can be modeled as
p(t) = 8.028e^0.025t million people, where t is the number of years since 1900.†
(a) What was the population of Mexico in 2006? (Round your answer to three decimal places.)
____________ million people
How rapidly was the population of Mexico growing in 2006? (Round your answer to three decimal places.)
____________ million people per year
(b) Write a linearization of p in 2006. (Round all numerical values to three decimal places.)
pL(t) = ______________
(c) Use linearization to estimate the population of Mexico in 2011. (Round your answer to three decimal places.)
_______________ million people
By answering the above question, we may state that As a result, in 2006, equation Mexico's population was expanding at a pace of around 2.708 million people each year.
What is equation?When two assertions are connected by a mathematical equation, the equals symbol (=) is used to denote equality. In algebra, a mathematical statement that establishes the equivalence of two mathematical expressions is referred to as an equation. In the equation 3x + 5 = 14, for instance, the equal sign places a space between the integers 3x + 5 and 14. To comprehend the connection between the two phrases written on the opposing sides of a letter, utilise a mathematical formula. Frequently, the logo and the specific piece of software are the same. as in, for instance, 2x - 4 = 2.
We must enter t = 2006 - 1900 = 106 into the population model and do the following calculations to get the population of Mexico in 2006:
p(106) = 8.028e (0.025 * 106) million individuals
108.191 million individuals, or p(106) (rounded to three decimal places)
Finding the derivative of the population model with respect to time t will allow us to determine how quickly Mexico's population was rising in 2006:
Each year, p'(t) = 0.025 * 8.028e(0.025t) million individuals.
We may then calculate the derivative at time t = 106 as follows:
P'(106) = 0.025 * 8.028e(0.025*106) million individuals annually P'(106) 2.708 million individuals annually (rounded to three decimal places)
As a result, in 2006, Mexico's population was expanding at a pace of around 2.708 million people each year.
