A company manufactures and sells mini-recorders. A survey of office supply stores indicated that at a price of $82 each, the demand would be four hundred recorders, and at a price of $42 each, the demand would be nine hundred recorders. If a linear relationship between price and demand exists, which of the following equations models the price-demand relationship?
(Let x represent the price per mini-recorder and y represent the demand in hundreds.)
A. Y= -1/8x + 57/4
B. Y= -8x - 114
C. Y= -1/8x - 57/4
D. Y= -8x + 114
Final answer:
Using the two given points $(82, 4)$ and $(42, 9)$, the slope is calculated to be $-1/8$. Subsequently, by using the point-slope form of the line equation and simplifying, we find that the linear relationship between price and demand is described by $y = -1/8x + 57/4$, which corresponds to choice A.
Explanation:
To determine the linear equation that best models the price-demand relationship for the mini-recorders, we are given two points. At a price of $82, the demand is 400 recorders (4 hundred), and at a price of $42, the demand is 900 recorders (9 hundred). In the mathematical representation, these points are (82, 4) and (42, 9), where x is the price and y is the demand in hundreds.
To find the slope (m) of the line, we use the slope formula:
m = (y2 - y1) / (x2 - x1), which gives us m = (9 - 4) / (42 - 82) = 5 / (-40) = -1/8.
Now, we can use the point-slope form to find the equation of the line. Let's use the point (82, 4):
y - y1 = m(x - x1)
y - 4 = (-1/8)(x - 82)
Multiplying out the right-hand side of the equation, we have:
y - 4 = (-1/8)x + (82/8)
y - 4 = (-1/8)x + 10.25
Moving 4 to the other side to get 'y' by itself, the equation becomes: y = (-1/8)x + 10.25 + 4
This simplifies to:
y = (-1/8)x + 14.25
Converting 14.25 into quarters gives us 14.25 = 57/4. Hence the equation becomes:
y = (-1/8)x + 57/4 which matches choice A.
Final answer:
The correct equation that models the price-demand relationship is y = -1/8x + 57/4, where y is the demand in hundreds and x is the price per mini-recorder.
Explanation:
To find the equation that models the price-demand relationship, we need two points to determine the line: (x1, y1) = (82, 4) and (x2, y2) = (42, 9). The demand, y, is in hundreds of recorders and x represents the price per mini-recorder. The slope (m) of the line is given by the change in demand over the change in price: m = (y2 - y1) / (x2 - x1) = (9 - 4) / (42 - 82) = 5 / (-40) = -1/8. To find the y-intercept (b), we use one of the points and the slope in the linear equation formula y = mx + b. Using the point (82, 4), we have 4 = (-1/8)(82) + b. Solving this equation gives us b = 4 + (1/8)(82) = 4 + 10.25 = 14.25. Now the linear equation is y = -1/8x + 14.25. Since y needs to be in hundreds for the units to match the point given (400, 900), we must divide b by 100, resulting in b = 14.25 / 100 = 57/4. The final price-demand relationship is y = -1/8x + 57/4.

Fifty students in the fourth grade class listed their hair and eye colors in the table below: Brown hair Blonde hair Total Green eyes 16 12 28 Brown eyes 14 8 22 30 20 50 Are the events "green eyes" and "brown hair" independent?
The events "green eyes" and "brown hair" are not independent because the probability of a student having both green eyes and brown hair is not equal to the product of their individual probabilities.
Explanation:To determine whether the events "green eyes" and "brown hair" are independent, we need to look at the probabilities of each event occurring separately and together.
The probability of having green eyes (P(Green Eyes)) is the total number of students with green eyes divided by the total number of students, which is 28/50.
The probability of having brown hair (P(Brown Hair)) is the total number of students with brown hair divided by the total number of students, which is 30/50.
The probability of having both green eyes and brown hair (P(Green Eyes AND Brown Hair)) is the number of students with both green eyes and brown hair divided by the total number of students, which is 16/50.
Events A and B are independent if P(A and B) = P(A) * P(B). Using this formula, we can determine if the events are independent:
P(Green Eyes AND Brown Hair) = P(Green Eyes) * P(Brown Hair)
16/50 ≠ (28/50) * (30/50)
Since the probability of having both green eyes and brown hair does not equal the product of the probabilities of having green eyes and having brown hair, these events are not independent.

Sonya wants to know how much her annual take-home pay will be after she pays FICA taxes totaling 7.65% on an annual salary of $36,590.
Final answer:
Sonya's annual take-home pay, after FICA taxes of 7.65% on her annual salary of $36,590, would be $33,790.86.
Explanation:
To calculate Sonya’s annual take-home pay after FICA taxes, we first need to understand that FICA consists of two separate taxes: Social Security and Medicare. The total rate for these combined is 7.65% of the gross income. Sonya’s annual salary is $36,590.
First, we calculate the total FICA tax Sonya has to pay:
Social Security tax (6.2% of $36,590) = $2,268.58Medicare tax (1.45% of $36,590) = $530.56Add these two amounts to get the total FICA tax:
$2,268.58 (Social Security) + $530.56 (Medicare) = $2,799.14
Finally, subtract this total FICA tax from the annual salary to find Sonya’s take-home pay:
$36,590 (annual salary) - $2,799.14 (FICA taxes) = $33,790.86

Two systems of equations are shown below: System A System B 3x + 2y = 3 −x − 14y = 1 −2x − 8y = −1 −2x − 8y = −1 Which of the following statements is correct about the two systems of equations? The value of x for System B will be one−third of the value of x for System A because the coefficient of x in the first equation of System B is one third times the coefficient of x in the first equation of System A. The value of x for System A will be equal to the value of y for System B because the first equation of System B is obtained by adding −4 to the first equation of System A and the second equations are identical. They will have the same solution because they represent the same lines when plotted on the coordinate axes. They will have the same solution because the first equation of System B is obtained by adding the first equation of System A to 2 times the second equation of System A.
The two linear equations represented in system A as :
3 x + 2 y =3 -------(1)
- 2 x - 8 y = -1 ------(2)
(1) × 2 + (2) × 3 gives
⇒ 6 x + 4 y - 6 x - 24 y = 6 -3
⇒ - 20 y = 3
⇒ y = [tex]\frac{-3}{20}[/tex]
Putting the value of y in equation (1), we get
[tex]3 x - \frac{6}{20}=3\\\\ 3 x= \frac{66}{20} \\\\ x=\frac{11}{10}[/tex]
Two linear equation represented in system B is:

[tex]-x + \frac{42}{20}=1 \\\\ x=\frac{22}{20}=\frac{11}{10}[/tex]
As Two system , that is system (A) and System (B) has same solution.
By looking at all the options , i found that Option (D) is correct. The two system will have the same solution because the first equation of System B is obtained by adding the first equation of System A to 2 times the second equation of System A.
Answer:
(D)
Step-by-step explanation:
Two linear equations by system A is given as:
[tex]3x+2y=3[/tex] (1)
[tex]-2x-8y=-1[/tex] (2)
Multiply equation (1) with 2 and equation (2) with 3 and then adding, we get
[tex]6x+4 y-6x-24y=6-3[/tex]
[tex]-20y=3[/tex]
[tex]y=\frac{-3}{20}[/tex]
Putting the value of y in equation (1), we get
[tex]3x-\frac{6}{20}=3[/tex]
[tex]3x=\frac{66}{20}[/tex]
[tex]x=\frac{11}{10}[/tex]
Two linear equations by system B is given as:
[tex]-x-14y=1[/tex] (3)
[tex]-2x-8y=-1[/tex] (4)
Multiply equation (3) with -2 and adding equation (4), we get
[tex]2x+28y-2x-8y=-2-1[/tex]
[tex]20y=-3[/tex]
[tex]y=\frac{-3}{20}[/tex]

[tex]-x+\frac{42}{20}=1[/tex]
[tex]x=\frac{11}{10}[/tex]
As Two system , that is system (A) and System (B) has same solution.
Thus, Option (D) is correct. The two system will have the same solution because the first equation of System B is obtained by adding the first equation of System A to 2 times the second equation of System A.
