The graph shows the number of quarts picked and the amount of money the customer paid.
Part A
What is the constant of proportionality, and what does it mean in this situation?
Answers
Answer:
Constant of proportionality k = 3.5
In our case, We can say that Amount of 1 quart is $3.5, and as the number of quarts bought are increased the amount paid is also increased at rate of $3.5.
Step-by-step explanation:
We need to find what is the constant of proportionality, and what does it mean in this situation?
Constant of proportionality can be defined as:
[tex]if\:y\:\alpha \:x\:then\:y=kx[/tex]
Where k is constant of proportionality
It tells that there is constant increase in the value of y.
Looking at the graph,
we get Number of Quarts (x) = 1, Amount Paid (y)= 3.5
so, finding constant of proportionality
[tex]y=kx\\3.5=k(1)\\k=3.5[/tex]
Now, Number of Quarts (x) = 2, Amount Paid (y)=7
so, finding constant of proportionality
[tex]y=kx\\7=k(2)\\k=\frac{7}{2}\\k=3.5[/tex]
So, for any value of x and y, the value of k remains constant i.e 3.5
So, constant of proportionality k = 3.5
In our case, We can say that Amount of 1 quart is $3.5, and as the number of quarts bought are increased the amount paid is also increased at rate of $3.5.

A therapist is studying the effects of meditation and yoga on reducing stress. He offers the treatments to a random sample of 30 of his patients and lets them choose which treatment they want to use.
Which of the following statements is not true about this experiment?
A The therapist let the patients choose the treatment; therefore, he will not be able to tell which treatment is more effective.
B The therapist used a random sample of 30 of his patients; therefore, he will be able to tell which treatment is more effective, yoga or meditation, in reducing stress.
C The therapist did not use random assignment; therefore, the variability between the patients is not evened out, and he will not be able to tell which treatment is more effective.
D The therapist used a random sample; however, the patients may choose which treatment they prefer, and their stress would be reduced due to their preference instead of the treatment.

Answer:
I think it is b
sorry it took so long I just seen your question
As per the question, the therapist is studying the effect of the meditation and yogi exercises on reducing the stress. He offers a Radom sample of 30 people to his patients and allows them to pick the treatment.
As the therapist uses a random sample of 30 thus the patients will be able to treatment is more effective and helps directly in reducing the stress levels.Hence the option B is correct.

Why is 2x 3/4 less than 2?
Answers
Answer & Step-by-step explanation:
It is less because 2 times 3/4 is the same as 2/1 times 3/4 which is 6/4 then simplify it and you get 3/2 which then is 1 1/2.
That is why 2 times 3/4 is less than 2.

Find x & y so that quadrilateral is a parallelogram. (Look at image)
Answers
Answer:
x = 5° y = 75
Step-by-step explanation:
Here given it is a quadrilateral
105° + y = 180° ( being co-interior angles)
y = 180° - 105°
y = 75°
Now
15x + 105° = 180° (being co-interior angles)
15x = 180° - 105°
15x = 75°
x = 75° / 15
x = 5°

Answer:
(3; 180°)
Step-by-step explanation:
The point (-3, 0) is located on the -x axis at a distance of 3 units from the origin. The -x axis is at an angle of 180° CCW from the +x axis. So, the polar coordinates are ...
r = 3
θ = 180°
This might be written as ...
(r; θ) = (3; 180°) = (3; π radians)

What is the slope of the line represented by the equation y = 4/5x-3
Answers
Mx = slope
B = y-intercept
So slope of the line is 4/5
*just pick one with the x and your good
Answer:
slope = [tex]\frac{4}{5}[/tex]
Step-by-step explanation:
The equation [tex]y = \frac{4}{5} x -3[/tex] is already written in slope-intercept form, or [tex]y = mx + b[/tex]. In this form, the number in place of the [tex]m[/tex] represents the slope. In this equation, the [tex]\frac{4}{5}[/tex] takes the place of that [tex]m[/tex], so the slope would be [tex]\frac{4}{5}[/tex].

Now we need to find the Circumference of the circle (perimeter of circle)
SO circumference formula is just
π*d
So in this case 17 *3.14 is 53.38
53.38 is the full Circumfrnce but divide that by 2 due to the circle being only half exposed
53.38/2=26.69
