A system of inequalities to represent the constraints of this problem are x ≥ 0 and y ≥ 0.

A graph of the system of inequalities is shown on the coordinate plane below.

In order to write a system of linear inequalities to describe this situation, we would assign variables to the number of HD Big View television produced in one day and number of Mega Tele box television produced in one day respectively, and then translate the word problem into algebraic equation as follows:

Since the HD Big View television takes 2 person-hours to make and the Mega TeleBox takes 3 person-hours to make, a linear equation to describe this situation is given by:

2x + 3y = 192.

Additionally, TVs4U’s total manufacturing capacity is 72 televisions per day;

x + y = 72

For the constraints, we have the following system of linear inequalities:

x ≥ 0.

y ≥ 0.

The number of trials (n) represents the group's size, and the probability of success (p) represents the population's proportion of extroverts or introverts.

(a) Assume that X is the proportion of extroverts among a team of 15 marketing employees. X exhibits a binomial distribution with n = 15 and p = 0.8 as its parameters.

The following formula can be used to determine the likelihood of having at least 10 extroverts:

Binom.cdf(9, 15, 0.8) = 0.836; P(X 10) = 1 - P(X 10) = 1 - P(X 9) = 1

The likelihood of having five or more extroverts can be determined using the formula below:

Binom.cdf(4, 15, 0.8) 0.999, P(X 5) = 1 - P(X 5) = 1 - P(X 4) = 1.

The following formula can be used to determine the likelihood that all 15 employees are extroverts:

The formula P(X = 15) = binom.pmf(15, 15, 0.8) 0.035

(b) Assume that there are Y introverts among the four computer programmers in the group. Y has a binomial distribution with n = 4 and p = 0.35 (because 65% of respondents identify as introverts, 35% must identify as extroverts).

The following formula can be used to determine the likelihood that none of the programmers are introverts:

P(Y = 0) is equal to binom.pmf(0, 4, 0.35) 0.150.

The following formula can be used to determine the likelihood that two or more programmers are introverts:

Binom.cdf(1, 4, 0.35) = 0.586 when P(Y 2) = 1 - P(Y 2) = 1 - P(Y 1) = 1.

a) At the time the article was published, the federal minimum wage was $5.85 per hour.

b) According to the US Department of Labor website, the federal minimum wage in 2008 was $6.55 per hour.  

c) To earn the current federal minimum wage of $7.25 per hour, a person must pick up a penny in 4.97 seconds.

d) The phrase "penny dreadful" is a British expression referring to cheaply printed stories of sensational and sometimes gruesome content that were sold for a penny in the 19th century.

A) The minimum wage when Owen wrote his article can be calculated by using the equation:

Minimum wage = (Amount of money earned)/(Amount of time taken to earn it)

In this case, the amount of money earned is $0.01 (the value of a penny) and the amount of time taken to earn it is 6.15 seconds. Therefore:

Minimum wage = ($0.01)/(6.15 seconds) = $0.00162601626 per second

To convert this to an hourly wage, we can multiply by the number of seconds in an hour (3600):

Minimum wage = ($0.00162601626 per second) x (3600 seconds per hour) = $5.85365854 per hour

Minimum wage =  $5.85

B) According to the U.S. Department of Labor, the federal minimum wage in 2008 was $6.55 per hour.

Therefore, Owen's arithmetic was slightly off, as his calculated minimum wage is lower than the actual minimum wage at that time.

C) To calculate how much time you would need to spend picking up a penny in order to earn the current minimum wage, we can use the same equation as before, but rearrange it to solve for the amount of time:

Amount of time = (Amount of money earned)/(Minimum wage)

The current federal minimum wage is $7.25 per hour, or $0.00201388889 per second. Therefore:

Amount of time = ($0.01)/($0.00201388889 per second) = 4.97 seconds

So you would need to spend 4.97 seconds picking up a penny in order to earn the current minimum wage.

D) The phrase "penny dreadful" refers to a type of cheap, sensationalist fiction that was popular in the 19th century. These stories were typically published in weekly installments and sold for a penny each, hence the name "penny dreadful."

Answer:

To approximate the monthly interest rate, we need to use the formula for the annual percentage rate (APR) that takes into account the effect of compounding:

APR = (1 + r/m)^m - 1

where r is the annual interest rate, m is the number of compounding periods per year, and APR is the annual percentage rate.

In this case, r = 11.1% and m = 12 (since there are 12 months in a year). We want to solve for the monthly interest rate, which we can call r_m:

r_m = (1 + r/12)^12 - 1

r_m = (1 + 0.111/12)^12 - 1

r_m = 0.009141

To convert this to a percentage, we multiply by 100:

r_m = 0.9141%

Therefore, the approximate monthly interest rate is 0.9141%, rounded to two decimal places.

Answer:

The slope of the given line on the graph is 1/3.

Answer:

1/3

Step-by-step explanation:

The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run" (change in y divided by change in x).

Let's start at 0 with x = 0 and y = 0 or (0,0)

You see the graph crosses coordinate (3,1)

so y goes from 0 to 1 => rise = 1

x goes from 0 to 3 => run = 3

then rise/run = 1/3

The equation of the circle that has center (-1,2) and passes through(-6,6) is (x + 1)^2 + (y - 2)^2 = 41.

The equation of a circle with center (h,k) and radius r is given by (x-h)^2 + (y-k)^2 = r^2. In this case, the center of the circle is (-1,2) so h = -1 and k = 2. We can use the given point (-6,6) to find the radius of the circle.

The distance between the center and the given point is the radius of the circle, and we can use the distance formula to find it:
r = √((-6 - (-1))^2 + (6 - 2)^2)
r = √((-5)^2 + (4)^2)
r = √(25 + 16)
r = √41

So the equation of the circle is:
(x - (-1))^2 + (y - 2)^2 = (√41)^2
(x + 1)^2 + (y - 2)^2 = 41

Therefore, the equation of the circle that has center(-1,2) and passes through(-6,6) is (x + 1)^2 + (y - 2)^2 = 41.

Answer: :)

Step-by-step explanation:

Let's start by setting up a proportion to represent the ratio of black tiles to white tiles:

1 black tile : 4 white tiles

We know that Eddie wants a total of 25 tiles in the design, so we can set up another proportion to represent the ratio of white tiles to the total number of tiles:

white tiles : 25 total tiles

To solve for the number of white tiles, we need to find the equivalent ratio of white tiles in terms of the total number of tiles. We can do this by cross-multiplying our two proportions:

1 black tile * (white tiles/4 black tiles) = white tiles/4

white tiles/25 total tiles = (white tiles/4) / (1 black tile + white tiles/4)

Simplifying this expression, we get:

white tiles/25 = (white tiles/4) / (5/4)

white tiles/25 = (1/4) * (white tiles/5)

5 * white tiles = 100

white tiles = 20

Therefore, Eddie will use 20 white tiles in his design.

The second largest share of the three entrepreneurs is $291,666.68.

To calculate the second largest share of the three entrepreneurs, we need to first find the total ratio by adding the three individual ratios: 3 + 4 + 5 = 12.

Next, we can find the value of one part of the ratio by dividing the total amount invested by the total ratio: $875,000 ÷ 12 = $72,916.67.

Finally, we can calculate the second largest share by multiplying the value of one part of the ratio by the second largest individual ratio, which is 4: $72,916.67 × 4 = $291,666.68.

Therefore, the amount of the second largest share is $291,666.68.

The inverse of a matrix is a matrix that, when multiplied by the original matrix, results in the identity matrix. To find the inverse of the given matrix [1 -1 0 -4 2 -1 4 3 3], we need to use the following steps:

Step 1: Find the determinant of the matrix. The determinant of a 3x3 matrix is given by:

|A| = a(ei - fh) - b(di - fg) + c(dh - eg)

where a, b, c, d, e, f, g, h, and i are the elements of the matrix. Plugging in the values from the given matrix, we get:

|A| = (1)(2*3 - (-1)*3) - (-1)(-4*3 - 0*4) + (0)(-4*(-1) - 2*4)

|A| = (1)(6 + 3) - (-1)(-12) + (0)(4 - 8)

|A| = 9 - 12 + 0

|A| = -3

Step 2: Find the matrix of minors. The matrix of minors is found by taking the determinant of each 2x2 matrix that can be formed by removing one row and one column from the original matrix. The matrix of minors for the given matrix is:

= [0  4  4]
 [-6 3 -4]
 [4 -4 -2]

Step 3: Find the matrix of cofactors. The matrix of cofactors is found by multiplying each element of the matrix of minors by -1 raised to the power of the sum of its row and column indices. The matrix of cofactors for the given matrix is:

[0  -4  4]
[6  3  -4]

The effective annual IRR (internal rate of return) is 8%. If the dollars invested and withdrawn and the inflation rate for the 19-year time span of the investment is 9% per year the inflation-free IRR is -0.92%.

To calculate this, we need to use the IRR formula: IRR = [Sum of cash flows / (-initial investment)]1/n - 1, where n is the number of periods.

a. To find the effective annual IRR earned on this investment, we can use the following formula:

0 = -10,000/(1+IRR) - 10,000/(1+IRR)^2 - 10,000/(1+IRR)^3 - 10,000/(1+IRR)^4 + 10,000/(1+IRR)^5 + 10,000(1-0.05)/(1+IRR)^6       + 10,000(1-0.05)^2/(1+IRR)^7 + ... + 10,000(1-0.05)^14/(1+IRR)^18

The effective annual IRR earned on this investment to the nearest percent is 8%.

b. To find the inflation-free IRR earned on this investment, we can use the following formula:

Inflation-free IRR = (1 + IRR)/(1 + inflation rate) - 1

Plugging in the values we found in part (a), we get:

Inflation-free IRR = (1 + 0.08)/(1 + 0.09) - 1 = -0.0092

Daniel bought 8 apples and 16 oranges. The equation we will use to solve the problem is 0.35x + 0.5(2x) = 5.4.

We know that Daniel bought twice as many oranges as apples, so let's call the number of apples he bought "x". Therefore, the number of oranges he bought would be "2x".

We also know that each apple cost $0.35 and each orange cost $0.50, so we can write the equation:

0.35x + 0.5(2x) = 5.4

Simplifying the equation, we get:

0.35x + x = 5.4 ÷ 0.5

0.35x + x = 10.8

1.35x = 10.8

x = 8

So, Daniel bought 8 apples, which means he also bought 2x = 16 oranges.

However, we need to check if this solution makes sense hence the cost of the apples would be:

0.35 × 8 = 2.8

d=69

f=180-69-32=79

The measure of each of the missing angles include the following:

d = 69.

e = 32.

f = 79.

In Geometry, the vertical angles theorem is also referred to as vertically opposite angles theorem and it states that two (2) opposite vertical angles that are formed whenever two (2) lines intersect each other are always congruent, which simply means being equal to each other.

By applying the vertical angles theorem to the geometric figure, we have the following:

m∠e = 32°

m∠d = 69°

From the linear postulate theorem, we have:

m∠e + m∠d + m∠f = 180°

32° + 69° + m∠f = 180°

m∠f = 180° - (32° + 69°)

m∠f = 79°

Answer:

Since the hexagon is a 2D shape, it does not have volume. We can find the area of a hexagon but not its volume.

Step-by-step explanation:

The ratio of the areas of two similar figures is equal to the square of the ratio of their corresponding side lengths. In this case, since the figures are hexagons, we can use the ratio of their corresponding side lengths to find the ratio of their areas.

Since the scale factor of the hexagons is 3:7, we know that the ratio of their side lengths is also 3:7. Therefore, the ratio of their areas is:

(3/7)^2 = 9/49

We are given that the area of the smaller hexagon is 18 m^2, so we can use this to find the area of the larger hexagon:

(area of larger hexagon) = (area of smaller hexagon) x (ratio of areas)

(area of larger hexagon) = 18 x (9/49)

(area of larger hexagon) = 3.28 m^2 (rounded to two decimal places)

Since the hexagon is a 2D shape, it does not have volume. We can find the area of a hexagon but not its volume.

Now, to find the fifth term of this sequence, we need to go back one term from the sixth term, which means we need to substitute n = 5 in the original formula:

A(5) = 6.3 + (5-1)(5)

A(5) = 6.3 + 20

A(5) = 26.3

Therefore, the fifth term of the sixth term of the sequence A(n) = 6.3 + (n-1)(5) is 26.3.

The total materials purchase usage variance is -P122.50.

The total materials cost variance is calculated by subtracting the total standard cost from the total actual cost. The total standard cost is P675.00 per batch and there were 14 batches produced during the month, so the total standard cost is P675.00 x 14 = P9,450.00. The total actual cost is calculated by multiplying the quantity purchased by the purchase price for each fruit and then adding them all together. The total actual cost is (300 x P9.50) + (150 x P22.00) + (350 x P7.20) + (80 x P15.40) = P2,850.00 + P3,300.00 + P2,520.00 + P1,232.00 = P9,902.00. The total materials cost variance is P9,902.00 - P9,450.00 = P452.00.

The materials yield variance is calculated by subtracting the standard quantity of materials from the actual quantity of materials used and then multiplying by the standard cost per liter. The standard quantity of materials is 60 liters per batch and there were 14 batches produced during the month, so the standard quantity of materials is 60 x 14 = 840 liters. The actual quantity of materials used is 290 + 130 + 350 + 75 = 845 liters. The materials yield variance is (840 - 845) x P10.00 = -P50.00.

The materials purchase usage variance is calculated by subtracting the standard cost per liter from the actual cost per liter and then multiplying by the actual quantity of materials used. The materials purchase usage variance for each fruit is (P9.50 - P10.00) x 290 + (P22.00 - P21.25) x 130 + (P7.20 - P7.50) x 350 + (P15.40 - P15.00) x 75 = -P145.00 + P97.50 - P105.00 + P30.00 = -P122.50. The total materials purchase usage variance is -P122.50.
