What is the median value of the data set shown on the line plot? Enter your answer in the box. A line plot with twenty-two data values. Labels are at zero, three, six, nine, and twelve. Tick marks are every one unit. Values appear as x marks above the line. Plot data values are one x mark above one, one x mark above two, two x marks above three, two x marks above four, three x marks above five, four x marks above six, three x marks above seven, three x marks above eight, two x marks above nine, and one x mark above eleven.
Answers
Please see the picture attached.
A line plot shows the number of occurrences (crosses) of each number of a data set.
The median is the central value, the middle number, of a data set ordered from least to greatest. When there are two middle numbers, the median will be the mean between the two.
In order to find the median, look at the line plot: count how many values you have (22), then add 1 (23) and divide by two (11.5). Since we have an even number of values, we will have two middle numbers, which will be in the eleventh and twelfth position.
Count the crosses from the left, the eleventh and twelfth crosses both correspond to the number 6, therefore the median is 6.
You can also write all the numbers in increasing order and divide them into two equal groups:
1, 2, 3, 3, 4, 4, 5, 5, 5, 6, 6 | 6, 6, 7, 7, 7, 8, 8, 8, 9, 9, 11
The median will be the average between the two central numbers, therefore 6 (again).

A corporation has agreed to donate money to a charity organization each time one of its employees donates to that charity organization. The corporation donates $3 for every $2 donated by an employee. The total amount the corporation donates to the charity organization is proportional to the total amount that its employees donate. Write an equation representing the relationship between c, the amount the corporation donates, and e, the amount its employees donate.
Answers
c =
$3 for every $2 is written as a fraction, since this is a proportional relationship:
[tex] \frac{3}{2} [/tex]
The independent variable here is "e" - the amount of money donated by the employees changes by itself. So when setting up our equation, "e" will be placed next to the proportion:
[tex] \frac{3}{2} e [/tex]
Our final equation will be:
c = [tex] \frac{3}{2} e [/tex]
Final answer:
The relationship between the amount the corporation donates and the amount its employees donate can be represented by the equation c = (3/2)e.
Explanation:

A 2/3 x + 3y = -3
B -2/3 x + 3y = 6
C x + 4y = 12
D 6x - 7y = 21
PLEAZ answer im in a hurry
Answers
Answer:
Option D.
Step-by-step explanation:
The given function is
[tex]y=\frac{2}{3}x-3[/tex]
Substitute x=0 in the given function to find the y-intercept.
[tex]y=\frac{2}{3}(0)-3=-3[/tex]
The y-intercept of the given function is -3. We need to find the equation whose y-intercept is -3.
Substitute x=0 in the given each of the equations to find the y-intercepts of those equation.
First equation is
[tex]\frac{2}{3}x+3y=-3[/tex]
[tex]\frac{2}{3}(0)+3y=-3[/tex]
[tex]3y=-3[/tex]
[tex]y=-1[/tex]
y-intercept is -1.
Second equation is
[tex]-\frac{2}{3}x+3y=6[/tex]
[tex]-\frac{2}{3}(0)+3y=6[/tex]
[tex]3y=6[/tex]
[tex]y=2[/tex]
y-intercept is 2.
Third equation is
[tex]x+4y=12[/tex]
[tex](0)+4y=12[/tex]
[tex]4y=12[/tex]
[tex]y=3[/tex]
y-intercept is 3.
Fourth equation is
[tex]6x-7y=21[/tex]
[tex]6(0)-7y=21[/tex]
[tex]-7y=21[/tex]
[tex]y=-3[/tex]
y-intercept is -3.
Therefore, the correct option is D.
The equation of the function that has the same y-intercept as [tex]y = \frac{2}{3}x - 3[/tex] is [tex]\mathbf{6x - 7y = 21}[/tex]. Both functions have the y-intercept of -3.
Recall:
Equation of a line in slope-intercept form is represented as: y = mx + b
y-intercept = b
m = slope
Given the function, [tex]y = \frac{2}{3}x - 3[/tex],
the y-intercept is -3
Rewrite each given option in the slope-intercept form to find which of the function has the same y-intercept value of -3 as in the function [tex]y = \frac{2}{3}x - 3[/tex].
Option A: [tex]\frac{2}{3} x + 3y = -3[/tex]
Rewrite as y = mx + b[tex]\frac{2}{3} x + 3y - \frac{2}{3} x = -\frac{2}{3} x -3\\\\3y = -\frac{2}{3} x -3\\\\3y \times \frac{1}{3} = -\frac{2}{3} x \times \frac{1}{3} -3 \times \frac{1}{3}\\\\\mathbf{y = -\frac{2}{9}x - 1}[/tex]
Thus, the y-intercept is -1Option B: [tex]-\frac{2}{3} x + 3y = 6[/tex]
Rewrite as y = mx + b[tex]-\frac{2}{3} x + 3y + \frac{2}{3} x = \frac{2}{3} x + 6\\\\3y = \frac{2}{3} x + 6\\\\3y \times \frac{1}{3} = \frac{2}{3} x \times \frac{1}{3} + 6 \times \frac{1}{3}\\\\\mathbf{y = \frac{2}{9}x + 2}[/tex]
Thus, the y-intercept is 2Option C: [tex]x + 4y = 12[/tex]
Rewrite as y = mx + b[tex]x + 4y - x= - x + 12\\\\4y = -x + 12\\\\4y \times \frac{1}{4} = -x \times \frac{1}{4} + 12 \times \frac{1}{4} \\\\\mathbf{y = -\frac{1}{4} x + 3}[/tex]
Thus, the y-intercept is 3Option D: [tex]6x - 7y = 21[/tex]
Rewrite as y = mx + b[tex]- 7y = -6x + 21 \\\\-7y \times -\frac{1}{7} = -6x \times -\frac{1}{7} + 21 \times -\frac{1}{7}\\\\\mathbf{y = \frac{6}{7}x - 3}[/tex]
Thus, the y-intercept is -3Therefore, the equation of the function that has the same y-intercept as [tex]y = \frac{2}{3}x - 3[/tex] is [tex]\mathbf{6x - 7y = 21}[/tex]. Both functions have the y-intercept of -3.

Which BEST describes the speed and velocity of the graph?
A)

B)
The speed and velocity remain constant.
C)
The speed is constant and velocity is changing.
D)
The velocity cannot be determined from the graph.
Answers
A - Both speed and velocity are changing.
Step-by-step explanation:Though the answer is option A but option D can also be true. The velocity cannot be completely determined from the graph. This is because, velocity is based on the direction and motion and the graph is not completely justifying this.
Though velocity cannot be determined, but it is clear from the graph that velocity is changing, because the speed is changing.
Therefore, option A is completely true.
A)
According to the graph, speed is increasing. Velocity is speed plus direction, so velocity is also changing. And this is an acceleration graph, so you know since acceleration is a change in velocity, both speed and velocity are changing.

-(18+4x)=8 hope you can help
Answers
Then you distribute
-18-4x=8
-4x=26
X= -6.5
-18 - 4x = 8 Then you can add -4x to the other side to make it positive and then subtract 8 to the other side to work on getting x all by itself.
-18 - 8 = 4x Then add your two negatives (because you add negatives when you have two of them because you are kind of making the answer more negative in a way :/ ) to get -26:
-26 = 4x Then divide by 4 to simplify and get x all by itself which leaves you with:
-6.5 = x (because when you divide a negative by a positive the quotient is negative) Check your answer by substituting -6.5 in for x in the original equation:
-[18 + 4(-6.5)] = 8 Multiply 4 times -6.5 (because you always start with the innermost parentheses) to get -26:
-(18 - 26) = 8 Change the signs because of the negative in the front:
-18 + 26 = 8 Subtract -18 from 26 to get 8
8 = 8 Correct! So your answer is x = -6.5!

The population of Adamsville grew from 7,000 to 12,000 in 5 years. Assuming uninhibited exponential growth, what is the expected population in an additional 5 years?
Answers
The expected population of Adamsville in an additional 5 years, assuming uninhibited exponential growth, is approximately 21,803 individuals.
Explanation:The question is based on exponential growth, a fundamental concept in mathematics. To solve for the population of Adamsville in the next 5 years, we need to know the growth rate. The formula for exponential growth is P = P0 * e^(rt), where:
P is the future populationP0 is the initial populationr is the exponential growth rate (as a decimal)t is time (in years)Given that the population grew from 7,000 to 12,000 in 5 years, it follows that 12,000 = 7,000 * e^(5r). Solving for r, we find that the annual growth rate is approximately 0.14496. Therefore, the estimated population in another 5 years would be P = 12,000 * e^(5 * 0.14496), which yields approximately 21,803. This suggests that if Adamsville's population continues to grow at an uninhibited exponential rate, in the next 5 years, it will reach roughly 21,803 individuals.
