The scale which Myron used to create the scale drawing of the school library is the scale of reduction and the scale represents 6 feet for 1 inch.

As we are given that Myron created a scale drawing of the school library in his art class. In the scale drawing, the length of the library is 13 inches and the actual length of the actual library is 78 feet.

So, the size of the drawing is less than the size of the actual length of the actual library.

So, it is the scale of reduction.

We can see:

13 inches represent the actual length of 78 feet.

1 inch will represent the actual length of 78 / 13 = 6 feet.

So, the scale represents 6 feet for 1 inch.

Thus, the scale which Myron used to create the scale drawing of the school library is the scale of reduction and the scale represents 6 feet for 1 inch.

The slope of the tangent line to the function f(x) = x**2+ 2x - 1 at the point x = 2. You can use the following procedures to figure out a tangent line's slope at a certain point on a curve.

You can use the following procedures to figure out a tangent line's slope at a certain point on a curve:

The purpose and the point should be clear. Say, for instance, that we are attempting to determine the slope of the tangent line to the function f(x) = x**2 + 2x - 1 at the point x = 2.

Calculate the function's derivative. The derivative in this situation is f'(x) = 2x + 2.

At the specified point, evaluate the derivative. The derivative is given by f'(2) = 2(2) + 2 = 6 when x = 2 is substituted.

The derivative at the point has the same slope as the tangent line's slope. The tangent line to f(x) at x = 2 therefore has a slope of 6, or six. The purpose and the point should be clear. Say, for instance, that we are attempting to determine the slope of the tangent line to the function f(x) = x**2+ 2x - 1 at the point x = 2.

Answer:

angle B = 33.42

Step-by-step explanation:

take angle B as reference angle

using tan rule

tan B = opposite/adjacent

tan B = 6/9

tan B = 0.66

B = \(tan^{-1} (0.66)\)

B = 33.424

B = 33.42

The solution to the inequality -3(1 - z) < 9 is z < 4.

To solve the inequality -3(1 - z) < 9, we can follow these steps:

Distribute the -3 on the left side of the inequality:

-3 + 3z < 9

Combine like terms:

3z - 3 < 9

Add 3 to both sides of the inequality to isolate the variable:

3z < 12

Finally, divide both sides of the inequality by 3 to solve for z:

z < 4

Brad needs to score between 59 and 95 on the fourth test to obtain a B for the semester.

To find the range of scores on the fourth test that would give Brad a B for the semester (an average between 80 and 89, inclusive), we can calculate the minimum and maximum scores he needs on the fourth test.

Brad's final average is the average of the four equally weighted 100-point tests. Let's denote the score on the fourth test as x.

The average of the four tests is:

(87 + 83 + 91 + x) / 4

To have a B for the semester (an average between 80 and 89, inclusive), the average score needs to be between 80 and 89.

So we have the following inequality:

80 ≤ (87 + 83 + 91 + x) / 4 ≤ 89

To find the minimum score Brad needs on the fourth test, we solve for x in the lower bound of the inequality:

80 ≤ (87 + 83 + 91 + x) / 4

Multiplying both sides of the inequality by 4:

320 ≤ 87 + 83 + 91 + x

Simplifying:

320 ≤ 261 + x

Subtracting 261 from both sides:

320 - 261 ≤ x

59 ≤ x

Therefore, Brad needs a score of 59 or higher on the fourth test to achieve a B for the semester.

To find the maximum score Brad can have on the fourth test, we solve for x in the upper bound of the inequality:

(87 + 83 + 91 + x) / 4 ≤ 89

Multiplying both sides of the inequality by 4:

87 + 83 + 91 + x ≤ 356

Adding up the known scores:

261 + x ≤ 356

Subtracting 261 from both sides:

x ≤ 356 - 261

x ≤ 95

Therefore, Brad needs a score of 95 or lower on the fourth test to achieve a B for the semester

It's actually not possible to solve this system of equations.

In order to solve for both 'x' and 'y', you need 2 INDEPENDENT equations.  "Independent" means you can't get one of them from the other one.

But in this pair, if you take the second equation, and multiply each side by 3, you get exactly the first equation.  So problem #6 actually gives you only one equation.  If you take either of these and massage it around for a little bit, you get  Y = -1.25x + 1.5 .  For either one.  They're both actually the same equation.

Problem #6 does not define one (X, Y) point.  It defines a line, that crosses the Y-axis at 1.5 and has a slope of -1.25.  EVERY POINT on that line is a solution to the one single equation that they gave you.

Answer:

B

Step-by-step explanation:

Functions/equations for straight lines are in the form:

\(y=mx+c\)

Where m is the slope/gradient and where c is the y-intercept.

All we have to do for this equation s just a simple switch of 2 terms to make it in this format. By the way g(x) and y are the same.

g(x) = 19.60+1.74x

Swap 19.60 and 1.74x:

g(x)=1.74x+19.60

Now we can see that m = 1.74 not 1.74x

The slope of the required line is -2 and the y-intercept of the required line is -10, giving the equation of the required line as \(y = -2x - 10.\)

Given the equation of the line: r - 2y = 5.Since the equation is not given in the form y = mx + b, we have to convert it to that form. Therefore, r - 2y = 5⇒ r = 2y + 5.Dividing both sides of the equation by 2, we get, y = (1/2)r - 5/2Comparing the given equation with y = mx + b, we get m = 1/2, b = -5/2.

Now, the given line is: y = (1/2)r - 5/2Since we need to find the equation of the line that is perpendicular to the given line, we need to find the slope of the line that is perpendicular to the given line. The slope of the given line is m = 1/2. The slope of the line that is perpendicular to this line is the negative reciprocal of 1/2.

The length of the rectangle = 21 cm

and the width of the rectangle = 19 cm

In this question, the length and width of a rectangle are consecutive odd integers.

Let n, n + 2 be the width and the length of a rectangle.

The perimeter of the rectangle is 80 centimeters.

Using the formula of the perimeter of the rectangle ,

P = 2 × [n + (n + 2)]

80 =  2(2n + 2)

40 = 2(n + 1)

20 = n + 1

n = 19

This means, the width of the rectangle is 19 centimeters.

And the length = n + 2

                         = 19 + 2

Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, translation and dilation.

Reflection is the flipping of a point about an axis. If a figure with point A(x, y) is reflected about the y axis, the new point is A'(-x, y)

The quadrilateral KLMN has vertices at K(-2, 6), L(-3, 8), M(-4, 4) and N(-3, 2). If the quadrilateral is reflected about the y axis, the new point is at:

Answer:

the angles of the triangle are 45 degrees, 60 degrees, and 75 degrees, and they are in the ratio of 3 : 4 : 5.

Step-by-step explanation:

Let's denote the angles of the triangle as 3x, 4x, and 5x, where x is a constant.

Since the sum of the angles of a triangle is 180 degrees, we can write the following equation:

3x + 4x + 5x = 180

Simplifying this equation, we get:

12x = 180

Dividing both sides by 12, we get:

x = 15

Therefore, the angles of the triangle are:

3x = 3(15) = 45 degrees

4x = 4(15) = 60 degrees

5x = 5(15) = 75 degrees

So the angles of the triangle are 45 degrees, 60 degrees, and 75 degrees, and they are in the ratio of 3 : 4 : 5.

The statement ''the symbol μ ˆ p represents the proportion of a sample of size n, not the proportion of a sample of size n.'' is false because the symbol "μ ˆ p" does not represent the proportion of a sample of size n.

In statistical notation, the symbol "μ ˆ p" typically represents the sample proportion, which is an estimate of the population proportion. The sample proportion is obtained by dividing the number of occurrences of a specific event in the sample by the sample size.

On the other hand, the population proportion, denoted by "p," represents the proportion of the entire population that exhibits a certain characteristic or has a specific attribute.

The symbol "μ ˆ p" could be a typographical error or a confusion between different symbols used in statistics. The correct symbol to represent the sample proportion is usually denoted as "p ˆ" or "p-hat." The symbol "μ" typically represents the population mean.

Therefore, it is incorrect to state that "μ ˆ p" represents the proportion of a sample of size n.

The term for the value that occurs most often in a series of numbers is called the mode.

The mode is one of the three main measures of central tendency, along with the mean and the median. It is a useful descriptive statistic that can provide insights into the characteristics of a dataset.

To find the mode of a set of data, you first need to arrange the data in order, either in increasing or decreasing order. Then, you simply identify the most frequent data point, which is the mode. In some cases, there may be more than one mode if multiple data points occur with the same maximum frequency.

The mode is particularly useful when dealing with categorical or nominal data, where there are distinct categories or values that cannot be ordered in a meaningful way. For example, the mode can help identify the most popular color among a group of people or the most common type of car on a given street. It can also be used for continuous data, although it may be less useful in this case than the mean or median.
