Answers

First, find the points for A and B.

A: (-9, 4)
B: (5, 4)

Because both of the points have the same y-coordinate value, we don't have to use the distance formula.

Simplify, find the difference between the x-coordinate values and find the absolute value of the difference.

|5 - (-9)| = |14| = 14

So, 14 units is the answer.

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?

Answers

Final answer:

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.

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

Answers

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.

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.

Answers

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) = $530.56

Add 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

For February, sales revenue is $900,000; sales commissions are 5% of sales; the sales manager's salary is $96,000; advertising expenses are $80,000; shipping expenses total 2% of sales; and miscellaneous selling expenses are $2,100 plus 1/2 of 1% of sales. Total selling expenses for the month of February are:

Answers

sales commission : 5% of 900,000....0.05(900,000) = 45,000
managers salary : 96,000
ads : 80,000
shipping : 2% of 900,000...0.02(900,000) = 18,000
misc. 2100 + 0.5(0.01(900,000)) = 2100 + 4500 = 6600
total selling expenses :
45,000 + 96,000 + 80,000 + 18,000 + 6600 = 245,600 <==

Final answer:

The total selling expenses for February amount to $245,600, calculated by adding the sales commissions, sales manager's salary, advertising expenses, shipping expenses, and miscellaneous selling expenses together.

Explanation:

To calculate the total selling expenses for the month of February, each component of the selling expenses will be computed based on the provided sales revenue, and then all these components will be summed up.

Sales commissions: 5% of $900,000 = $45,000

Sales manager's salary: $96,000 (fixed cost)

Advertising expenses: $80,000 (fixed cost)

Shipping expenses: 2% of $900,000 = $18,000

Miscellaneous selling expenses: $2,100 + 0.5% of $900,000 = $2,100 + $4,500 = $6,600

Adding all these expenses together:

$45,000 + $96,000 + $80,000 + $18,000 + $6,600 = $245,600

Therefore, the total selling expenses for the month of February are $245,600.

Which of these is a simplified form of the equation 6y + 4 = 8 + 2y + 2y? 6y = 8 10y = 12 2y = 4 4y = 12

Answers

6y + 4 = 8 + 2y + 2y
6y + 4 = 8 + 4y
6y - 4y = 8 - 4
2y = 4
       6y+4 = 8+2y+2y
<=> 6y+4 = 8+ y(2+2)
<=> 6y+4 = 8+4y (we add (-4y) on both sides)
<=> 6y+4 - 4y = 8
<=> y(6-4) + 4 = 8
<=> 2y + 4 = 8 (we add (-4) on both sides)
<=> 2y = 8-4
<=> 2y = 4

Write the equation y=-3/5x+3 in standard form using integer coefficients

Answers

y=-3/5x+3
3/5x+y=3
3x+5y=15

Final answer: 3x+5y=15

Final answer:

To convert the equation y = -3/5x + 3 into standard form with integer coefficients, multiply both sides by 5 to get rid of the fraction, resulting in 5y = -3x + 15. Then, rearrange the terms to obtain the standard form, which is 3x + 5y = 15.

Explanation:

The equation y = -3/5x + 3 is given in slope-intercept form. To convert it into standard form using integer coefficients, we need to rearrange the terms so that all variables and constants are on one side of the equation and the constant is on the other side. The standard form of a linear equation is Ax + By = C, where A, B, and C are integers, and A should be non-negative.

First, multiply both sides of the equation by 5 to clear the fraction:

5y = -3x + 15

Next, move the x-term to the left side of the equation:

3x + 5y = 15

Now, the equation is in standard form with integer coefficients.

The answer is 1.5, as the statement says it is one (one whole) and a half (half a whole, 0.5)

The tongue of a chameleon is 1.5 times its body length when expressed as a decimal.

If the tongue of a chameleon is one and a half times its body length, we express this as a decimal by multiplying the body length by 1.5. For example, if the body length is represented by 1 unit, then the tongue length would be 1  imes 1.5, which equals 1.5. Therefore, the length of the tongue as a decimal is 1.5 times the body length.
