Bo and Erica are yoga instructors. Between the two of them, they teach 43 yoga classes each week. If Erica teaches 11 fewer than twice as many as Bo, how many classes does each instructor teach per week?

Answers

Answer 1

Answer:

Erica teaches 32.33 or 32 classes

Bo teaches 10.67 or 10 classes

Step-by-step explanation:

B + E = 43

E - 11 = 2B

B + E = 43

E = 43 - B

E - 11 = 2B

(43 - B) - 11 = 2B

B = 10.67 = 10

B + E = 43

(10.67) + E = 43

E = 32.33 = 32

What is triangle?

A triangle is a three-sided polygon with three angles. It is a fundamental geometric shape and is often used in geometry and trigonometry. A triangle is defined by its three sides and the three angles formed by those sides. The sum of the three angles in a triangle is always 180 degrees. Triangles can be classified based on the length of their sides and the size of their angles.

Using Pythagoras theorem of right triangle

DB² = DC² + BC²

Here given that

DC = BC

Then

DB² = DC² + DC²

DB² = 5² + 5²

DB² = 25 + 25

DB² = 50

What is triangle?

A triangle is a three-sided polygon with three angles. It is a fundamental geometric shape and is often used in geometry and trigonometry.

To reflect a point or a shape across a line, you can follow these steps:

Find the equation of the line of reflection.

Find the distance between each point and the line of reflection.

Reflect each point across the line of reflection by moving the same distance on the other side of the line.

Finding the equation of the line of reflection:

The line of reflection is y = -2, which is a horizontal line passing through y = -2.

Finding the distance between each point and the line of reflection:

We can use the formula for the distance between a point (x, y) and a line Ax + By + C = 0:

distance = |Ax + By + C| / sqrt(A^2 + B^2)

Plugging in the values, we get:

distance(A, y = -2) = |(-2) - (-2) + 2| / sqrt(0 + 1) = 2

distance(B, y = -2) = |(-2) - (-2) + 4| / sqrt(0 + 1) = 4

distance(C, y = -2) = |(-5) - (-2) + 2| / sqrt(1 + 0) = 5 / sqrt(1) = 5

So the distances between A, B, C and the line of reflection are 2, 4, and 5, respectively.

Reflecting each point across the line of reflection:

To reflect a point across a line, we move the same distance on the other side of the line. Since the line of reflection is horizontal, we only need to move vertically.

A is 2 units above the line of reflection, so we move it 2 units below the line:

A' = (-2, -2)

B is 4 units above the line of reflection, so we move it 4 units below the line:

B' = (-2, -4)

C is 5 units above the line of reflection, so we move it 5 units below the line:

C' = (-5, -7)

Therefore, the coordinates of the vertex A' are (-2, -2).

On the second day, 2 of the sharks have the original tags. On the third day, 4 of the sharks have the original tags. Based on the data, what is the estimated population of great white sharks that have migrated from Mexico to Hawaii?​

Therefore, the estimated population of great white sharks that have migrated from Mexico to Hawaii is 2,500.

What is Shark Population Estimation?

Shark population estimation is the process of determining the size and trends of shark populations in a given area. It involves collecting and analyzing data on shark abundance, distribution, behavior, and other factors to understand their population dynamics.

There are different methods used to estimate shark populations, including mark-recapture studies, aerial surveys, acoustic tracking, and genetic analysis. These methods allow researchers to estimate the number of sharks in a given area, monitor changes in their population over time, and identify potential threats to their survival.

To estimate the population of great white sharks that have migrated from Mexico to Hawaii, we can use the capture-recapture method, also known as the Lincoln-Petersen index.

Let:

N = the total population sizen1 = the number of sharks tagged in Mexicon2 = the number of sharks captured in Hawaii on the first dayn3 = the number of sharks captured in Hawaii on the second dayn4 = the number of sharks captured in Hawaii on the third daym1 = the number of sharks captured in Hawaii on the first day that were previously taggedm2 = the number of sharks captured in Hawaii on the second day that were previously taggedm3 = the number of sharks captured in Hawaii on the third day that were previously tagged

The Lincoln-Petersen index formula is:

[tex]N = (n_1 * n_2 * n_3) / (m_1 * m_2 * m_3)[/tex]

A. multiplying the first equation by 2 B. multiplying the first equation by 6 C. multiplying the second equation by 2 D. multiplying the second equation by 6.

Answers

The correct answer is A. Multiplying the first equation by 2 will eliminate the variable y.

What is elimination method?

The elimination method is a common technique used to solve a system of linear equations. In this method, we manipulate the equations by adding or subtracting them to eliminate one of the variables, so that we can solve for the other variable.

According to question:

To eliminate one of the variables, we need to choose one of the equations and multiply it by a constant that will make the coefficient of one of the variables in that equation equal to the coefficient of the same variable in the other equation, but with the opposite sign. Then, when we add the two equations together, the term with that variable will be eliminated.

Looking at the given equations, we can see that if we multiply the first equation by 2, we will get:

6x - 12y = 16

And if we add this equation to the second equation, we get:

6x - 12y + 2x + 3y = 16 - 1

Simplifying this, we get:

8x - 9y = 15

Now we have one equation with only x and y, and we can use this equation and either of the original equations to solve for x and y using the substitution method.

Therefore, the correct answer is A. Multiplying the first equation by 2 will eliminate the variable y.

In Euclidean geometry, a rectangle is a parallelogram with four small angles. It may also be defined as a fundamental rule hexagon or one in which all of the angles are equal. Another alternative for the parallelogram is a straight angle. Four of the vertices of a square are the same length. A quadrilateral with four 90° angle vertices and equal parallel sides has a rectangle-shaped cross section. As a result, it is also known as a "equirectangular rectangle." A rectangle is sometimes referred to as a parallelogram due to the equal and parallel dimensions of its two sides.

We must determine the size of the darkened zone.

The bigger rectangle (with the frame) has a surface area of (12+2) x (10+2) = 14 x 12 = 168 square units.

The smaller rectangle (with the frame) has an area of (8+2) x (6+2) = 10 x 8 = 80 square units.

The frame's area is equal to the difference between the two areas: 168 - 80 = 88 square units.

What is confidence interval?

A set of values that, with a particular level of confidence, is likely to include an unknown population parameter is known as a confidence interval. Confidence intervals are frequently utilized in statistics to calculate the actual value of a population parameter using sample statistics. When comparing a sample statistic to a population parameter that is hypothesised, we utilize confidence intervals to assess if the difference is statistically significant.

Given the interval of the result in the survey is [0.38, 0.41].

a. The point estimate is given as:

Point estimate = (0.38 + 0.41) / 2 = 0.395

b. The margin of error is given as:

Margin of error = (critical value) x (standard error)

Assuming a 95% confidence level:

Standard error = (maximum error) / (critical value)

Now,

Maximum error = (0.41 - 0.38) / 2 = 0.015

Margin of error = 1.96 x (0.015 / 1.96) = 0.015

What is triangle ?

Three straight ends and three angles make up a closed triangle, a two-dimensional geometric object. A triangle's angles add up to 180 degrees in all cases. Based on their side lengths and angle measurements, triangles can be categorized in a variety of ways. Typical categorizations comprise: Triangle having no equal sides is referred to as a scalene triangle. Isosceles triangle: A triangle with two sides of equal length. A triangle having an equilateral shape is one with three equal sides. Triangle that has all angles that are less than 90 degrees is referred to as an acute triangle. Triangle with one angle that is precisely 90 degrees is referred to as a right triangle. A triangle that has a side that is more acute than 90 degrees is said to be obtuse.

given

In the isosceles obtuse triangle, let x represent the measurements of each equal angle.

One of the equal angles is bigger than 90 degrees since the triangle is obtuse. As a result, we have:

x + x + 20 = 180 (sum of angles of a triangle) (sum of angles in a triangle)

When we simplify this equation, we obtain:

2x + 20 = 180

2x = 160

x = 80

Hence, each of the equal angles is 80 degrees in length. As a result, there are three different ways to measure the angles in the isosceles obtuse triangle, which has one angle that is 20 degrees, as follows:

Answers

The range of the normal curve representing 95% of the scores fall is equal to 40.2 to 59.8.

The range within which 95% of the scores fall,

Calculate the z-scores corresponding to the 2.5th and 97.5th percentiles of the normal distribution.

The z-score corresponding to the 2.5th percentile is -1.96.

And the z-score corresponding to the 97.5th percentile is +1.96.

Using the formula for the z-score, we can calculate the corresponding raw scores as,

Lower bound is equal to,

z = (X - μ) / σ

⇒-1.96 = (X - 50) / 5

⇒X = 40.2

Upper bound is equal to,

z = (X - μ) / σ

⇒ +1.96 = (X - 50) / 5

⇒ X = 59.8

Describe Triangles?

In mathematics, a triangle is a geometric shape that consists of three line segments that intersect at three endpoints. These endpoints are called vertices, and the line segments are called sides.

Triangles are one of the most basic shapes in geometry and are used in many areas of mathematics, science, engineering, and everyday life. They can be classified based on the length of their sides and the measure of their angles.

Some common types of triangles include:

Equilateral triangle: A triangle in which all three sides are equal in length.

Isosceles triangle: A triangle in which two sides are equal in length.

Scalene triangle: A triangle in which all three sides have different lengths.

Right triangle: A triangle in which one angle measures 90 degrees (a right angle).

To find the value of x, we can use the trigonometric ratios of a right-angled triangle. Let's call the base of the triangle "b".

We know that the angle between the hypotenuse and the base is 45 degrees, which means that the other acute angle is also 45 degrees. Therefore, we can use the trigonometric ratio for the sine of 45 degrees to relate the hypotenuse and the perpendicular as follows:

sin(45 degrees) = opposite/hypotenuse

where the opposite side is the perpendicular, which is given as 4√2.

sin(45 degrees) = 4√2/x

Simplifying this equation gives:

x = 4√2 / sin(45 degrees)

We know that sin(45 degrees) = 1/√2, so substituting this value into the equation above gives:

x = 4√2 / (1/√2) = 4√2 * √2 = 8

Therefore, the value of x is 8.

How to obtain the sum of the ages of the family?

The sum of the ages of the family is obtained applying the proportions in the context of the problem.

Each year, the age of each person increases by one, hence, considering a family of five, the yearly increase in the age of the family is given as follows:

5 x 1 = 5 years.

The two youngest are 6 and 8, meaning that seven years ago, the youngest was not yet born.

The ages of a family of five sum to 80, hence the sum seven years ago was given as follows:

80 - 5 x 7 = 45 years.

3 A camper wants to protect her bag of food from bears She decides to tightly stretch a rope between two trees and hang her bag from a point exactly halfway along the length of the rope The first tree is 10 feet east and 6 feet north of her firepit The second tree is 5 feet west and 8 feet north of her firepit The rope is attached at a height of 8 feet to the first tree and a height of 5 feet to the second tree Let the firepit represent the origin movement east of the firepit represent movement in the direction of positive x movement west of the firepit represent movement in the direction of negative x movement north of the firepit represent movement in the direction of positive y and movement above the firepit represent movement in the direction of positive z 1 Write the coordinates of the points on the trees where the rope is attached 2 Find the distance between the points in part a Use sqrt to indicate a square root For example 3 would be written sqrt 3 3 Find the coordinates of the point where the food bag is hung 4 If the food bag is 1 2 feet long when hung and bears can reach a height of 7 5 feet when standing is the camper s food safe from bears Explain why or why not

Answers

The coordinates of the point where the food bag is hung are (2.5, 7, 6.5).

What is the coordinate point called?

The center of the coordinate system (where the lines intersect) is called the origin. The axes intersect when both x and y are zero. The coordinates of the origin are (0, 0). An ordered pair contains the coordinates of one point in the coordinate system.

The coordinates of the point on the first tree where the rope is attached are (10, 6, 8), and the coordinates of the point on the second tree where the rope is attached are (-5, 8, 5).

To find the distance between the points, we can use the distance formula:

distance = √((x2 - x1)² + (y2 - y1)² + (z2 - z1)²)

Plugging in the coordinates from part 1, we get:

distance = √((-5 - 10)² + (8 - 6)² + (5 - 8)²)

distance = √(225 + 4 + 9)

distance = √(238)

Therefore, the distance between the points is √(238).

Since the food bag is hung at a point exactly halfway along the length of the rope, we can find its coordinates by taking the average of the coordinates of the points where the rope is attached.

The x-coordinate of the midpoint is: (10 + (-5)) / 2 = 2.5

The y-coordinate of the midpoint is: (6 + 8) / 2 = 7

The z-coordinate of the midpoint is: (8 + 5) / 2 = 6.5

Therefore, the coordinates of the point where the food bag is hung are (2.5, 7, 6.5).

To determine whether the food is safe from bears, we need to compare the height of the food bag to the maximum height that bears can reach. The food bag is hung at a height of 6.5 feet, and bears can reach a height of 7.5 feet when standing. Therefore, the food is not completely safe from bears, as they may be able to reach it if they stand up on their hind legs. However, hanging the food bag at this height does make it more difficult for the bears to reach, and may deter them from trying to get to it. It is also important to note that proper food storage techniques in bear country should involve using bear-resistant containers, in addition to hanging food bags.

The track team jog for 3/8 of a mile in the morning in the afternoon they jog for 3/4 of a mile did they jog longer in the morning or the afternoon explain

Answers

The team jogged longer in the afternoon because they covered a distance of 6 eighths of a mile, which is greater than the 3 eighths of a mile they covered in the morning.

To compare the distance jogged in the morning and afternoon, we need to find the common unit for both. We can convert both fractions to have the same denominator by finding the least common multiple (LCM) of 8 and 4, which is 8.

So, in terms of eighths of a mile, the distance jogged in the morning is:

3/8 miles = 3 eighths of a mile

And the distance jogged in the afternoon is:

3/4 miles = 6 eighths of a mile (since 3/4 = 6/8)

Therefore, the team jogged longer in the afternoon because they covered a distance of 6 eighths of a mile, which is greater than the 3 eighths of a mile they covered in the morning.

true or false? square root functions are either always increasing or always decreasing for the whole domain of

Answers

The given statement square root functions are not always increasing or always decreasing for the whole domain of ( -∞ , ∞) is false.

Function is square root function.

Domain = ( -∞ , ∞)

Square root functions is always increasing or decreasing is a false statement.

For example,

Let us consider the function f(x) = √x.

This function is increasing for x > 0, since as x increases, √x increases as well.

However, for x < 0, the function is not defined since the square root of a negative number is not a real number.

This implies,

The function is neither increasing nor decreasing for x < 0.

Therefore, the statement square root functions are either always increasing or always decreasing for the whole domain of ( -∞ , ∞)  is false.

what does the median tell farrah about her data

Answers

The median provides Farrah with an understanding of the central value in her data set, which can help her analyze the overall distribution of the data points.

The median is a measure of central tendency that tells Farrah the middle value of her data when it is arranged in ascending order.

To find the median, Farrah should follow these steps:
1. Arrange her data in ascending order (from smallest to largest).
2. If there is an odd number of data points, the median is the middle value.
3. If there is an even number of data points, the median is the average of the two middle values.

It is less affected by outliers or extreme values than the mean, making it a more reliable representation of the center of her data.

The area of a rectangular room is 84 ft^2. the length of the room is 8ft greater than the width. The situation can be represented as W^2-8w-84=0. What is the width?

Answers

Answer:

Step-by-step explanation:

You can start by drawing a diagram.  Then, you need to pick the shorter side and designate it as "x".  The longer side must be "x+8".

The formula for area of a rectangle is A=l*w.  Since the area is 84, then you can use the A=l*w formula.  84 = x(x+8) would be the equation to solve for x.

Now, you need to put the equation in standard form.  So, x2 + 8x - 84 = 0.

Since you can't solve this quadratic using factoring, you need to complete the square.

To complete the square you need to add 84 to both sides.  Now you have x2 + 8x = 84.  Take the coefficient for the x term (8) and divide by 2.  Now square it.  That would be 42, so 16.  Now you have x2 +8x +16 = 100.

Factor x2 +8x +16, so (x+4)2 = 100

If you use the square root property, you have x+4 = 10.  Therefore, x = 6 (the short side) and 14 is the long side.

I hope that helps.
