To find how many classes each instructor teaches per week, you need to set up and solve a system of equations based on the given information. In other words,
Let x be the number of classes Bo teaches per week and y be the number of classes Erica teaches per week.
The first equation is based on the total number of classes they teach
x + y = 37
The second equation is based on the relationship between their numbers of classes
y = 2x - 14
To solve this system, you can use substitution or elimination methods. For example, using substitution, you can plug in y = 2x - 14 into the first equation and get
x + (2x - 14) = 37
Simplify and solve for x
3x - 14 = 37
So, Bo teaches 17 classes per week and Erica teaches 20 classes per week.

3x + y = -10
3x + y = 10
3x - y = -10
3x - y = 10
The equation of the line y = 3x + 10 in standard form is 3x - y = -10.
What is the equation of line in standard form?Given the equation of line in the question:
y = 3x + 10
To write the equation of the line in standard form, we need to rearrange the equation so that the x and y terms are on the left side and the constant term is on the right side of the equation.
It is expressed as;
Ax + Bx = C
y = 3x + 10
Subtracting 3x from both sides, we get:
y - 3x = 3x - 3x + 10
y - 3x = 10
Reorder
-3x + y = 10
Multiply each term by -1
-3x(-1) + y(-1) = 10(-1)
3x - y = -10
Therefore, the equation in standard form is 3x - y = -10.

how do we ensure trigonometric functions compute values appropriately? what is the value of this expression?
We can ensure trigonometric functions compute values appropriately by validating the results against known values. In order to ensure that the argument is in a short interval surrounding a place where an approximation is highly accurate, one performs a range reduction prior to computing things like a cos or sin.
By comparing the results to established values, we can make sure trigonometric functions compute values correctly. As an example, if we wanted to validate the cosine of 45 degrees, we could compare the result to the known value of 0.707. If the computed value is within a small margin of error of the known value, then we can assume the trigonometric function is computing values appropriately.
In order to calculate functions like cos or sin, one must first perform a range reduction to make sure the input is inside a narrow range surrounding a point where an approximation is highly accurate. It is typically close to zero.

Between which two benchmarks is 3/8 how do you know?
Answer:
Step-by-step explanation:
To find the benchmarks between which 3/8 falls, we need to identify the nearest fractions with denominators that are multiples of 8.
The fraction 3/8 is halfway between 1/4 and 1/2, which can be written as 2/8 and 4/8 respectively. So, we know that 3/8 is greater than 2/8 and less than 4/8.
Therefore, the benchmarks between which 3/8 falls are 2/8 and 4/8. Alternatively, we can express these fractions as decimals and say that 3/8 falls between 0.25 and 0.5.
13. security y has the following returns over five years: 3%, 6%, 0%, 6%, and 3%. what is the arithmetic mean (average) return and the standard deviation (sample) for security y?
The arithmetic mean return is 3.6%, and the standard deviation is 2.14%.
To find the arithmetic mean, we add up the five returns and divide by the number of returns (in this case, 5):
(3% + 6% + 0% + 6% + 3%) / 5 = 3.6%
To find the standard deviation, we first need to find the variance. We can do this by taking each return, subtracting the mean return (3.6%), squaring the result, summing these values, and dividing by the number of returns minus 1 (4 in this case):
((3% - 3.6%)^2 + (6% - 3.6%)^2 + (0% - 3.6%)^2 + (6% - 3.6%)^2 + (3% - 3.6%)^2) / 4 = 0.046
The standard deviation is the square root of the variance:
√0.046 = 0.214 or 2.14%
Therefore, the arithmetic mean return for security y is 3.6%, and the standard deviation (sample) is 2.14%.

Answer:
1. No, the side lengths 3, 5, and 9 cannot make a triangle.
2. If you are scaling an object by ¹/₃, it makes the object smaller.
If the real object is 30 inches long, it is 10 inches once it is scaled.
3. A cube has 6 faces.
To find the volume, cube the side length: 6³ = 216 in³
Step-by-step explanation:
Question 1According to the Triangle Inequality Theorem, the sum of any two sides of a triangle is greater than the length of the third side.
As the sum of the two sides measuring 3 and 5 is 8, and 8 is not greater than 9, the side lengths 3, 5, and 9 cannot make a triangle.
Question 2Scaling an object reduces or enlarges its size. When scaling an object:
If the scale factor is greater than 1, the object becomes larger. If the scale factor is between zero and 1, the object becomes smaller.Therefore, if you are scaling an object by ¹/₃, the object becomes smaller, since ¹/₃ is between zero and 1.
To scale length, simply multiply the length by the scale factor.
Therefore, if a real object is 30 inches long, its length once it is scaled is:
[tex]\implies \sf 30 \times \dfrac{1}{3}=\dfrac{30}{3}=10\;inches[/tex]
Question 3A cube is a three-dimensional solid shape with six square faces.
The volume of a cube is the product of its width, length and height.
If the side of a cube measures 6 inches, its volume is:
[tex]\begin{aligned}\implies \sf Volume &=\sf 6 \times 6 \times 6 \\&= \sf 36 \times 6 \\&= \sf 216\;in^3\end{aligned}[/tex]
Answer:
See below, please.
Step-by-step explanation:
Ans 1.
In order to make a triangle, three line segments are needed, and the sum of the lengths of any two sides must be greater than the length of the remaining side. The side lengths 3, 5, and 9 cannot make a triangle because 3 + 5 is less than 9, which violates the triangle inequality.
Ans 2.
Scaling an object by 3 makes the object larger, as each dimension (length, width, and height) is multiplied by 3. If the real object is 30 inches long and is scaled by 3, it will be 90 inches long.
Ans 3.
A cube has 6 faces. To find the volume of a cube when one side measures 6 inches, we use the formula V = s^3, where s is the length of one side. Plugging in s=6, we get V = 6^3 = 216 cubic inches.

plum island lighthouse, shines a light from a height of 34 feet with a 2 degree angle of depression. how far out can this light reach into the harbor?
Plum Island Lighthouse can light up the harbor 974.44 feet away from its base.
The angle of depression refers to the angle at which an observer is looking down from an object to a point of reference below. If the angle of depression is increased, the distance from the object to the point of reference decreases. When there is a 2-degree angle of depression, the following formula is used to determine the distance between the observer and the point of reference (in this case, the harbor):tan θ = opposite/adjacent
where θ is the angle of depression, opposite is the height of the object, and adjacent is the distance between the object and the point of reference. Tan 2 = 34/x where x is the distance between the lighthouse and the harbor.tan 2 = 0.03492The angle of depression must be converted to radians to use a calculator.θ = 2π/360 = 0.03491 radians

Produce an equivalent equation for f(x)=7(x-60)-28 to reveal the y-intercept for the function. What is the y-intercept?
The equivalent equation to f(x) = 7(x - 60) - 28 is f(x) = 7x - 448 and the y-intercept is -448
How to determine the equivalent equationGiven that
f(x) = 7(x - 60) - 28
To produce an equivalent equation that reveals the y-intercept of the function f(x) = 7(x-60) - 28, we need to simplify the expression by evaluating it when x = 0, since this will give us the y-intercept.
When the brackets are expanded, we have the following
f(x) = 7x - 420 - 28
Evaluate the like terms
So, we have
f(x) = 7x - 448
So, substituting x = 0 into f(x) gives:
f(0) = 7(0) - 448
Evaluate the expression
f(0) = -448

When on a stem and leaf plot and it does not show a number on the right side and only on the right side, the number on the right side would be zero.
What is a stem and leaf plot?A stem and leaf plot is a method of organizing numerical data into groups. It is a visual representation of a dataset in which each value is separated into a stem and a leaf. A stem is the left-hand digit(s) of the value, while a leaf is the right-hand digit(s).
The stem and leaf plot contains two columns, one for the stem and the other for the leaf. The stem values are arranged vertically in the left-hand column, and the leaf values are arranged horizontally in the right-hand column. The leaf column should be read from left to right to extract the values.
When a value appears multiple times, its leaves are stacked on top of one another. The stem and leaf plot is an effective method for representing data, particularly when dealing with large datasets.
Hence, If a stem and leaf plot displays a number only on the left side and not on the right side, then the number on the right side would be interpreted as zero.

The following questions are about the relationship between the determinant of M and the ability to solve the equation above for A in terms of X or for X in terms of A Check the boxes which make the statement correct: If the det (M) then A. A. some values of Xl will have more than one value of Al which satisfy the equation. B. some values of Al will have no values of Xl which will satisfy the equation.C. given any X there is one and only one A which will satisfy the equation. D. there is no value of X which satisfies the equation when A=0. E. some values of A (such as A=0 ) will allow more than one X to satisfy the equation.
In conclusion, the determinant of M being non-zero only guarantees that the equation has a unique solution, but it does not guarantee that it has a solution for every value of A.
If the determinant of M is not equal to zero, then A can be solved in terms of X or X can be solved in terms of A. This is because the matrix M is invertible when its determinant is non-zero. In other words, the matrix M has a unique inverse.
Here are the statements that are correct:
- Given any X, there is one and only one A which will satisfy the equation. This is because when the determinant of M is non-zero, the matrix M is invertible, and hence the equation can be uniquely solved for A in terms of X or for X in terms of A.
- Some values of A (such as A=0) will allow more than one X to satisfy the equation. This is because the determinant of M being non-zero only guarantees that the equation has a unique solution, but it does not guarantee that it has a solution for every value of A.
- Some values of X will have more than one value of A that satisfy the equation. This is true for any equation that has multiple solutions, regardless of the determinant of M.
- Some values of A will have no values of X that satisfy the equation. This is true for any equation that has no solution, regardless of the determinant of M.
- There is no value of X which satisfies the equation when A=0. This is because when A=0, the equation reduces to 0=0, which is true for any value of X.
