This means that there are 3 students who scored within that range. Therefore, the correct answer is C. 3.

The histogram displays the test scores for the 19 students in the geometry class. To determine how many students scored from 110 to 119 points, we need to look at the height of the bars in that range.

A histogram is a graphical representation of data that displays the frequency or distribution of a set of continuous or discrete variables. It consists of a series of bars, where each bar represents a specific category or range of values, and the height of the bar corresponds to the frequency or count of observations falling within that category or range.

Based on the histogram, we can see that the bar representing the range from 110 to 119 points has a height of 3. This means that there are 3 students who scored within that range. Therefore, the correct answer is C. 3.

The graph of the function f(x) = -2sin(x) starts at the midline (y = 0) and reaches its maximum or minimum point closest to the midline at (π/2, -2).

Start by plotting the midline, which is the x-axis (y = 0). This is the starting point for the graph.

Find the maximum or minimum point on the graph closest to the midline. In this case, the maximum or minimum point is a maximum point because the coefficient of sin(x) is negative (-2). The maximum point occurs at π/2 on the x-axis.

Plot the maximum point on the graph at (π/2, -2). This point represents the highest or lowest point on the graph closest to the midline.

From the maximum point, the graph will start to decrease. Since the coefficient of sin(x) is -2, the graph will have a steeper slope compared to the graph of sin(x).

As x increases from π/2, the graph will continue to decrease until it reaches the next minimum point, which will be at 3π/2.

Continue plotting points on the graph by evaluating the function at various x-values and connecting them smoothly to create a sinusoidal curve.

Repeat the pattern of the graph for every interval of 2π, as the sine function is periodic.

Finally, label the x-axis as "x" and the y-axis as "f(x)" or "y" to indicate the function being graphed.

Step-by-step explanation:

are the what???

Answer

Price of the 6 pounds of Trail Mix = 18 dollars

Explanation

Let the amount of raisins in 6 pounds of Trail Mix be x pounds.

And the amount of almonds in 6 pounds of Trail Mix be y pounds.

We know that the sum of x and y has to give 6 pounds.

x + y = 6

But we know that there are 2 more pounds of Raisins than Almonds in the 6 pounds of Trail Mix

x = y + 2

x + y = 6

y + y + 2 = 6

2y + 2 = 6

2y = 6 - 2

2y = 4

Divide both sides by 2

(2y/2) = (4/2)

y = 2

x = y + 2 = 2 + 2 = 4

So, we know that there are 4 pounds of Raisin and 2 pounds of Almonds in the 6 pounds of Trail Mix.

1 pound of Raisins = 2 dollars

4 pounds of Raisin = 4(2) = 8 dollars

1 pound of Almonds = 5 dollars

2 pounds of Almonds = 2(5) = 10 dollars

Price of 6 pounds of Trail Mix

= (Price of 4 pounds of Raisins) + (2 pounds of Almonds)

= 8 + 10

= 18 dollars

Step-by-step explanation:

The reliability of the machine can be estimated to be 0.9833, calculated as (1000 - 1) / 1000 + (600 - 5) / 600.  we can take the average of the two reliability estimates, giving us a reliability of 0.9833.

The reliability of a machine can be estimated by taking the ratio of machines that did not fail to the total number of machines operated in a given period. In this case, the reliability of the machine from Factory A can be estimated to be 0.99 (1000 - 1 / 1000). The reliability of the machine from Factory B can be estimated to be 0.9833 (600 - 5 / 600). To estimate the reliability of the machine based on both factories, we can take the average of the two reliability estimates, giving us a reliability of 0.9833.

It takes a train going 50 mph approximately 11/2 miles to stop safely.

The distance a train takes to come to a stop can be determined by several factors, including the speed of the train, the weight of the train, the condition of the brakes and the track, and the reaction time of the engineer.

In general, a train going 50 mph will take about 1 1/2 miles or 8,000 feet to stop safely. This is because a train moving at 50 mph is traveling at about 75 feet per second, and it takes a significant distance to slow down a heavy object moving at such a high speed. It's important to note that this is an estimation, and the actual stopping distance may vary depending on the specific conditions.

The main disadvantage of the experimental method is the lack of informed consent. Data is typically analyzed using statistical techniques.

A disadvantage of the experimental method is that participants are not asked to provide informed consent. This statement is not accurate. In ethical research, obtaining informed consent is a fundamental requirement, regardless of the research method used. Informed consent ensures that participants are fully aware of the nature of the study, its purpose, potential risks and benefits, and their rights as participants. It allows individuals to make an informed decision about their participation, and it is crucial for upholding ethical standards and protecting participants' autonomy and well-being.

Regarding the second part of your question, data obtained through the experimental method are typically analyzed using statistical techniques. Statistical analysis allows researchers to examine the data and draw conclusions based on the results.

This analysis can involve various methods, such as hypothesis testing, confidence intervals, regression analysis, ANOVA (analysis of variance), t-tests, chi-square tests, and others, depending on the research question and the type of data collected.

The goal is to analyze the data in a way that allows researchers to make inferences and draw conclusions about the relationships between variables or the effects of experimental manipulations.

Answer:

12,662 books

Step-by-step explanation:

Total number of books = 75,972

No. of science books = ⅓ of 75,972 = ⅓*75,972 = 25,324 books.

No. of business books = 75% of the remaining books = 75% of (75,972 - 25,324)

= \( \frac{75}{100}*50,648 = 37,986 \)

No. of business books = 37,986

No. of maths books in the math section = 75,972 - (25,324 + 37,986)

= 75,972 - 63,310

= 12,662 books

Step-by-step explanation:

Domain x€[0,+infinity] means x≥0

Range

The domain of the function is all real numbers except x = -1/4, as this value make the denominator zero. The vertical asymptote is located at x = -1/4.

The given rational function does not have a hole as there is no common factor in both the numerator and denominator that can be canceled out.

The vertical asymptote of a rational function is a vertical line where the function approaches infinity or negative infinity.

In this case, the denominator of the fraction becomes zero when 4x+1=0, which means x=-1/4. So, the vertical asymptote of the given function is the vertical line x = -1/4.

The horizontal asymptote of a rational function is a horizontal line that the function approaches as the absolute value of x gets very large. To find the horizontal asymptote,

we need to compare the degrees of the numerator and denominator of the fraction. In this case, the degree of the numerator is 0 and the degree of the denominator is 1.

Therefore, the horizontal asymptote is y = 0/1 = 0. So, the horizontal asymptote of the given function is the horizontal line y = 0.

In summary, for the given rational function f(x) = (3/4x + 1) - 7:

Radus: 2, Center (3,-4)

Step-by-step explanation:

You first move the constant to the right then reorder the terms: x^2+y^2-6x+8y=-21.

You then complete the square: x^-6x+9+y^2=-21+9

Then factor: (x-3)^2+y^2+8y=-12

Then complete the square for the other term:

(x-3)^2+y^2+8y+12=-12+16

Then factor: (x-3)^2+(y+4)^2=4

4 is the radius squared, so the radius must be 2.

The center is the opposite of the constant in the parenthesis so the center must be (3,-4)
