To know the use of Computer Lab in the School
A Survey has been done.Out of the four Question asked,
The education of the trainer in the computer Lab does not come into consideration,to know the use of computer lab in the school, the use of computer lab can be known only by whether students are getting well versed with Computer and it's applications or not.
Number of Learning Stations in the computer lab, also can't tell the use of computer Lab in the school, because we have to check knowledge of the students about computers to know the better use of the Lab.
So, number of Class projects, or in my own words A test on computer awareness and It's software tools will be a better survey Question.
Option D is the question in the survey is a STATISTICAL QUESTION.
(D) How many class projects did you complete using the computer lab?

The dimensions of a room measure 12ft by 9ft. In a scale drawing of a room, 1 inch= 3ft. What are the dimensions of the room in the drawing?
Final answer:
To calculate the scale drawing dimensions of a room that measures 12ft by 9ft with a scale of 1 inch=3ft, divide each dimension by the scale factor. The room would be 4 inches by 3 inches on the scale drawing.
Explanation:
To find the dimensions of the room in the drawing when given that 1 inch=3 feet, we need to set up a conversion based on the scale provided. The room measures 12 feet by 9 feet, so we must divide each dimension by the scale factor to convert feet to inches in the drawing.
First, calculating the length:
12 feet ÷ 3 feet/inch = 4 inches
Next, calculating the width:
9 feet ÷ 3 feet/inch = 3 inches
Therefore, the dimensions of the room on the scale drawing would be 4 inches by 3 inches.

the equation y equals 1/5x represents a proportional relationship. explain how you can tell the relationship is proportional from the graph of the equation, and how can you find the constant of proportionality
Answer:
Sample answer: When you graph the equation, you get a straight line that passes through the origin, which means the relationship is proportional. The constant of proportionality is the y-value when x = 1, which is 1/5.

Jake wants to compare the mean height of the players on his favorite badminton and basketball teams. He creates the dot plots shown below:
First dot plot is labeled Height of Badminton Players and shows 1 cross on 66, 1 cross on 69, 2 crosses on 70, 2 crosses on 71, 4 crosses on 72, 6 crosses on 73, 4 crosses on 74, 1 cross on 76, and 1 cross on 78. Second dot plot is labeled Height of Basketball Players and shows 3 crosses on 72, 2 crosses on 75, 2 crosses on 76, 2 crosses on 78, 2 crosses on 79, 2 crosses on 80, 2 crosses on 81, 2 crosses on 82, and 1 cross on 84
The mean absolute deviation is 1.74 inches for the badminton team and 3.02 inches for the basketball team. Which of the following conclusions can be drawn from the data?
The badminton players are all taller than the basketball players.
The basketball players are all taller than the badminton players.
There is more variability in the badminton team member heights.
There is more variability in the basketball team member heights.
There is more variability in the basketball team member heights.
Mean Absolute Deviation, or MAD, describes the variability of a model. The greater the MAD, the more variability there is in the data. Since the MAD of the basketball players is higher than that of the badminton players, the basketball team members' heights vary more.

Option C has the greatest rate of change.
The increasing linear function with the greatest unit rate is represented by the table in option B. The unit rate is 0.5.
Explanation:The table that represents the increasing linear function with the greatest unit rate is option B (x y 2 14 6 12). In this table, as the value of x increases by 4, the value of y increases by 2. This gives us a unit rate of 2/4 or 0.5.
For the other options:
A. The unit rate is (-6)/3 = -2
C. The unit rate is 9/3 = 3
D. The unit rate is -4/4 = -1
E. The unit rate is (-17-(-19))/(6-2) = -2

a rectangular porch has dimentions of (x+12) and (x+5) feet. If thr aria of the porch floor is 120 square feet, what is its length and width?
To find the length and width of the rectangular porch, solve the equation (x+12)(x+5) = 120 for x. The length is x+12 feet, and the width is x+5 feet. Substitute the value of x to find the length and width.
Explanation:To find the length and width of the rectangular porch, we need to solve the equation (x+12)(x+5) = 120 for x. Expanding the equation, we get x^2 + 17x + 60 = 120. Rearranging the terms and solving for x, we find x = 5. So the length of the porch is x+12 = 5+12 = 17 feet, and the width is x+5 = 5+5 = 10 feet. Therefore, the porch has a length of 17 feet and a width of 10 feet.

Find the area. The figure is not drawn to scale
Answer: The area of the figure is (D) 704 in².
Step-by-step explanation: We are given to find the area of the figure.
We can see that the given figure is a parallelogram with two sets of parallel and congruent sides 22 in and 40 inch. And the height of the parallelogram is 32 in.
The area of a parallelogram with base 'b' units and height 'h' units is given by
[tex]A=b\times h.[/tex]
In the given figure,
base, b = 22 in and height, h = 32 in.
Therefore, the area of the parallelogram is
[tex]A=b\times h=22\times 32=704~\textup{in}^2.[/tex]
Thus, the area f the figure is 704 in².
Option (D) is correct
The parallelogram's area can be found by multiplying the base and height, resulting in 704 in² (option D).
The given figure is a parallelogram with two sets of parallel and congruent sides, measuring 22 inches and 40 inches, and a height of 32 inches. To find the area of the parallelogram, we use the formula A = b * h, where 'b' is the base length and 'h' is the height.
Given:
Base, b = 22 inches
Height, h = 32 inches
Using the formula, the area (A) of the parallelogram is:
A = 22 * 32
A = 704 square inches
So, the area of the figure is 704 square inches. Option (D) is the correct answer.
In conclusion, the parallelogram's area can be found by multiplying the base and height, resulting in 704 in². This confirms that option (D) is the correct answer to the problem.

show work please and will give brainlyist
Out of the given options, the number of students with blue eyes, brown eyes, and hazel eyes can be determined using the information provided in the question.
Explanation:Let's assume the number of students with hazel eyes is x. According to the given information, the number of students with blue eyes is 2 less than x, so it is x - 2. Additionally, there are twice as many students with brown eyes, so the number of students with brown eyes is 2x. The total number of students in the class is given as 34, so we can set up an equation:
x + (x - 2) + 2x = 34
Simplifying this equation, we get 4x - 2 = 34. Adding 2 to both sides, we have 4x = 36. Dividing both sides by 4, we find that x = 9.
Therefore, the number of students with blue eyes is 9 - 2 = 7, the number of students with brown eyes is 2(9) = 18, and the number of students with hazel eyes is 9. Thus, the correct options are a. 8, c. 12, and f. 34.

The width and length of the bulletin board are whole numbers what is the width of the bulletin board if the length is 4 feet
The width of the bulletin board cannot be determined with the given information, as any whole number could be the width if only the length is known to be 4 feet.
Explanation:The question asks for the width of the bulletin board given that the length is 4 feet, and we are told that both measurements are in whole numbers. Without additional information about the actual measurement of the width or the relation between the length and the width, we cannot determine the width exactly. Since the length is 4 feet, which is a whole number, the width could be any whole number. The width could be the same as the length if the bulletin board is square, or it could be different if the board is rectangular.
Since we know that 1 yard is equivalent to 3 feet, it's relevant when converting between these units of measure, but this information is not directly helpful for determining the width without further details. If we had a ratio, scale factor, or additional information regarding the relationship between the length and width, then we could proceed with a mathematical calculation to find the width. For example, if the bulletin board were to have a given aspect ratio or if the problem stated that the width is a certain multiple of the length, then we could use that information to calculate the width.
The width of the bulletin board is 4 feet.
Explanation:To find the width of the bulletin board, we need to know the scale factor between the length and width. Since the length is given as 4 feet, we can assume that the width is also in feet. Therefore, the width of the bulletin board is also 4 feet.
