The amount that Josephine will be paid is $644.30.

A percentage is a value or ratio that may be stated as a fraction of 100. If we need to calculate a percentage of a number, we should divide it's entirety and then multiply it by 100. The percentage therefore refers to a component per hundred.

In this situation, Josephine earns a salary of $560.00 per week, plus a commission of 10% on all sales and she sold $843 worth of goods.

The amount she'll be paid will be:

= $560 + (10% × $843)

= $560 + $84.3

= $644.30

We can infer that the set of vectors represented by (-1, 2), (8, 4) is orthogonal in Rⁿ since their dot product is equal to zero.

We must determine whether the dot product of any two vectors in the set is equal to zero in order to demonstrate the orthogonality of the set of vectors in Rⁿ.

Let's determine the dot product of the vectors provided:

(-1, 2) ⋅ (8, 4) = (-1)(8) + (2)(4)

(-1, 2) ⋅ (8, 4) = -8 + 8

(-1, 2) ⋅ (8, 4) = 0

We can infer that the set of vectors (-1, 2), (8, 4) is orthogonal in Rⁿ because the dot product of (-1, 2) and (8, 4) equals zero.

the probability that a woman selected at random has a blood pressure between 114 and 128 is 0.5588.

A z-table also known as the standard normal distribution table, helps us to know the percentage of values that are below (or to the left of the Distribution) a z-score in the standard normal distribution.

Given the mean is 121 while the standard deviation of the women is 9. Therefore, Using the z-table, the probability can be found.

(a) The probability that a woman selected at random has blood pressures greater than 136.

\(P(x > 136) = 1 - P(x < 136)\\\\P(x > 136) = 1 - P(z < \dfrac{x-\mu}{\sigma})\)

                  \(=1 - P(z < \dfrac{136-121}{9})\\\\=1 - P(z < 1.667)\\\\=1-0.9515\\\\=0.0485\)

(b) The probability that a woman selected at random has a blood pressure less than 114.

\(P(x < 114)= P(z < \dfrac{114-121}{9})\\\\\)

                  \(= P(z < -0.77)\\\\= 0.2206\)

(c) The probability that a woman selected at random has a blood pressure between 114 and 128.

\(P(114 < x < 128)= P(\dfrac{114-121}{9} < z < \dfrac{128-121}{9})\\\\\)

                  \(= P(-0.77 < z < 0.77)\\\\= P(z < 0.77)-P(z < -0.77)\\\\= 0.7794 - 0.2206\\\\=0.5588\)

Hence, the probability that a woman selected at random has a blood pressure between 114 and 128 is 0.5588.

Therefore, the solution to the system of linear equations is: x₁ = -5, x₂ = 11, x₃ = -18.

To solve the system of linear equations:

3x₁ + 2x₂x₃ = 10

-x₁ + 3x₂ + 2x₃ = 5

x₁ - x₂ - x₃ = -1

We can use various methods such as substitution, elimination, or matrix methods. Here, we'll use the elimination method.

Step 1: Multiply the second equation by 3 and add it to the first equation:

3x₁ + 2x₂x₃ = 10

-(3x₁ - 9x₂ - 6x₃ = 15)

-7x₂ - 4x₃ = -5 (Equation A)

Step 2: Multiply the third equation by 3 and add it to the first equation:

3x₁ + 2x₂x₃ = 10

(3x₁ - 3x₂ - 3x₃ = -3)

-x₂ - x₃ = 7 (Equation B)

Step 3: Add Equation A and Equation B:

-7x₂ - 4x₃ = -5

+(-x₂ - x₃ = 7)

-8x₂ - 5x₃ = 2 (Equation C)

Step 4: Multiply Equation B by 8 and subtract it from Equation C:

-8x₂ - 5x₃ = 2

+8x₂ + 8x₃ = -56

3x₃ = -54

Step 5: Solve for x₃:

x₃ = -54/3

x₃ = -18

Step 6: Substitute the value of x₃ back into Equation B to solve for x₂:

-x₂ - x₃ = 7

-x₂ - (-18) = 7

-x₂ + 18 = 7

-x₂ = 7 - 18

-x₂ = -11

x₂ = 11

Step 7: Substitute the values of x₂ and x₃ into Equation A to solve for x₁:

-7x₂ - 4x₃ = -5

-7(11) - 4(-18) = -5

-77 + 72 = -5

-5 = -5

The equation 6|2x + 5| = 6x + 24 has two solutions: x = -1 and x = -3.

To solve the equation 6|2x + 5| = 6x + 24, we need to isolate the variable x. Here's a step-by-step explanation:

1. Remove the absolute value bars by considering both the positive and negative cases:
  a) For 2x + 5 ≥ 0 (positive case):
     Simplify the equation to get 6(2x + 5) = 6x + 24.
  b) For 2x + 5 < 0 (negative case):
     Multiply the entire equation by -1 to flip the inequality sign and change the direction: 6(-2x - 5) = 6x + 24.

2. Solve for x in each case:
  a) Positive case:
     Simplify the equation to get 12x + 30 = 6x + 24.
     Combine like terms: 12x - 6x = 24 - 30.
     Simplify further: 6x = -6.
     Divide both sides by 6: x = -1.
  b) Negative case:
     Simplify the equation to get -12x - 30 = 6x + 24.
     Combine like terms: -12x - 6x = 24 + 30.
     Simplify further: -18x = 54.
     Divide both sides by -18: x = -3.

3. Check if the obtained values satisfy the original equation:
  Substitute x = -1 into the original equation: 6|2(-1) + 5| = 6(-1) + 24.
  Simplify both sides: 6|-2 + 5| = -6 + 24.
  Further simplify: 6|3| = 18.
  Since both sides are equal, x = -1 is a valid solution.
 
  Substitute x = -3 into the original equation: 6|2(-3) + 5| = 6(-3) + 24.
  Simplify both sides: 6|-6 + 5| = -18 + 24.
  Further simplify: 6|-1| = 6.
  Again, both sides are equal, so x = -3 is also a valid solution.

Therefore, the equation 6|2x + 5| = 6x + 24 has two solutions: x = -1 and x = -3.

To find the perimeter of this triangle, we add up all the sides together.

(8 · √3) + (8 · √3) + √384

But before we add them, let's simplify them.

(8 · 1.7) + (8 · 1.7) + 19.6

13.6 + 13.6 + 19.6

27.2 + 19.6

= 46.8, is the perimeter of this triangle.

Now to find the area, we use the formula:

(formula for area of a triangle)

A = BH · 1/2

Where 'B' represents the base, 'H' stands for the height, and 1/2 means that you divide the product of the base and height by 2.

What we know:

Plug in the values into our formula:-

A = BH · 1/2

A = 13.6(13.6) · 1/2

A = 184.96 · 1/2

A = 184.96/2

A = 92.48, is the area for this triangle.

Therefore, the population increases by 3516 cattle between the 5th and 9th years.

To find the population increase between the 5th and 9th years, we need to calculate the integral of the given rate function (400 + 80t) with respect to t from 5 to 9.
Step 1: Find the integral of the rate function.
∫(400 + 80t) dt = 400t + 40t^2 + C
Step 2: Calculate the population increase at t = 5 and t = 9.
For t = 5: 400(5) + 40(5^2) = 2000 + 1000 = 3000
For t = 9: 400(9) + 40(9^2) = 3600 + 2916 = 6516
Step 3: Find the difference between these two values.
Total increase = 6516 - 3000 = 3516

To find the equation of the line passing through the mid-point of the line segment joining (2, -6) and (-4, 2) and perpendicular to the line y = -x + 2, we need to follow the steps mentioned below.

Step 1: Find the mid-point of the line segment joining (2, -6) and (-4, 2).The mid-point of a line segment with endpoints (x1, y1) and (x2, y2) is given by[(x1 + x2)/2, (y1 + y2)/2].

So, the mid-point of the line segment joining (2, -6) and (-4, 2) is[((2 + (-4))/2), ((-6 + 2)/2)] = (-1, -2)

Step 2: Find the slope of the line perpendicular to y = -x + 2.

The slope of the line y = -x + 2 is -1, which is the slope of the line perpendicular to it.

Step 3: Find the equation of the line passing through the point (-1, -2) and having slope -1.

The equation of a line passing through the point (x1, y1) and having slope m is given byy - y1 = m(x - x1).

So, substituting the values of (x1, y1) and m in the above equation, we get the equation of the line passing through the point (-1, -2) and having slope -1 as:

\(y - (-2) = -1(x - (-1))⇒ y + 2\)

\(= -x - 1⇒ y\)

\(= -x - 3\)

Hence, the equation of the line passing through the mid-point of the line segment joining (2, -6) and (-4, 2) and perpendicular to the line y = -x + 2 is

The X value corresponding to z = -2.00 is 60. The X value corresponding to z = -2.00 is 60. This means that the observation with a z-score of -2.00 is 60 units below the population mean of 80.

To find the X value corresponding to z = -2.00, we can use the formula:
z = (X - µ) / σ
Substituting the given values, we get:
-2.00 = (X - 80) / 10
Solving for X, we get:
X = (-2.00 x 10) + 80
X = 60

The z-score measures the number of standard deviations an observation is from the mean. In this case, the given z-score of -2.00 indicates that the observation is 2 standard deviations below the mean.
To find the corresponding X value, we use the formula:
z = (X - µ) / σ
Where z is the standard normal distribution value, X is the corresponding raw score, µ is the mean of the population, and σ is the standard deviation of the population.
Substituting the given values, we get:
-2.00 = (X - 80) / 10

Consider the time taken to completion time (in months) for the construction of a particular model of homes: 4.1 3.2 2.8 2.6 3.7 3.1 9.4 2.5 3.5 3.8 Find the mean, median mode, first quartile and third quartile. Find the outlier?

To find the mean, we add up all the values and divide by the number of values:

Mean = (4.1 + 3.2 + 2.8 + 2.6 + 3.7 + 3.1 + 9.4 + 2.5 + 3.5 + 3.8) / 10

Mean = 36.7 / 10

Mean = 3.67

To find the median, we need to put the values in order:

2.5, 2.6, 2.8, 3.1, 3.2, 3.5, 3.7, 3.8, 4.1, 9.4

The middle number is the median, which is 3.35 in this case.

To find the mode, we look for the value that appears most often. In this case, there is no mode as no value appears more than once.

To find the first quartile (Q1), we need to find the value that separates the bottom 25% of the data from the top 75%. We can do this by finding the median of the lower half of the data:

2.5, 2.6, 2.8, 3.1, 3.2

The median of this lower half is 2.8, so Q1 = 2.8.

To find the third quartile (Q3), we need to find the value that separates the bottom 75% of the data from the top 25%. We can do this by finding the median of the upper half of the data:

3.7, 3.8, 4.1, 9.4

The median of this upper half is 3.95, so Q3 = 3.95.

To find the outlier, we can use the rule that any value more than 1.5 times the interquartile range (IQR) away from the nearest quartile is considered an outlier. The IQR is the difference between Q3 and Q1:

IQR = Q3 - Q1

IQR = 3.95 - 2.8

IQR = 1.15

1.5 times the IQR is 1.5 * 1.15 = 1.725.

The only value that is more than 1.725 away from either Q1 or Q3 is 9.4. Therefore, 9.4 is the outlier in this data set.

To find the perimeter of a regular polygon with n sides, we can use the formula:

Perimeter = n * s

where s is the length of each side. To find s, we can use trigonometry to find the length of one of the sides and then multiply by the number of sides.

In a regular polygon with n sides, the interior angle at each vertex is given by:

Interior angle = (n - 2) * 180 degrees / n

In a 15-sided polygon, the interior angle at each vertex is:

(15 - 2) * 180 degrees / 15 = 156 degrees

If we draw a line from the center of the polygon to a vertex, we form a right triangle with the side of the polygon as the hypotenuse, the distance from the center to the vertex as one leg, and half of the side length as the other leg. Using trigonometry, we can find the length of half of the side:

sin(78 degrees) = 12 / (1/2 * s)

s = 2 * 12 / sin(78 degrees)

s ≈ 2.17 inches

Finally, we can find the perimeter of the polygon:

Perimeter = 15 * s

Perimeter ≈ 32.55 inches

Rounding this to the nearest whole number, we get that the best approximation for the perimeter is 33 inches. Therefore, the closest option is (1) 68 inches.
