The company now has 675 employees after adding 35% more employees to the initial 500 employees.

A figure or ratio that may be stated as a fraction of 100 is a percentage. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100.

To calculate the total number of employees after adding 35%, you can multiply the initial number of employees by 1.35:

Total number of employees = 500 x 1.35

Total number of employees = 675

Therefore, the company now has 675 employees after adding 35% more employees to the initial 500 employees.

We would need to study 678 families to determine the market preference for baby shampoo brands with a 96% confidence level and 4% margin of error, given that there are 12,000 families with babies in the sector of interest.

To calculate the sample size needed to determine the market preference for baby shampoo brands, we can use the formula:

n = [(Z^2 * p * q) / E^2]

where:

n = sample size

Z = Z-score for the desired level of confidence (in this case, 1.96 for a 96% confidence level)

p = proportion expected (in this case, 0.12 or 12%)

q = 1 - p

E = margin of error (in this case, 0.04 or 4%)

Substituting these values into the formula, we get:

n = [(1.96^2 * 0.12 * 0.88) / 0.04^2] = 677.16

Since we cannot have a fraction of a family, we round up the sample size to 678 families. Therefore, we would need to study 678 families to determine the market preference for baby shampoo brands with a 96% confidence level and 4% margin of error, given that there are 12,000 families with babies in the sector of interest.

The correct option is C. mean, that is Mr. Greene should use the mean temperature, which is 77.86°F.

In mathematics, the mean value is a measure of central tendency of a set of numbers. It is also known as the arithmetic mean and is found by adding all the numbers in a set and dividing the sum by the total number of values. The mean is commonly used to represent the typical or average value of a set of data. It is a useful tool in statistics and other branches of mathematics for analyzing data and making predictions. The mean value can be affected by outliers or extreme values in a set of data, which can skew the results. However, in many cases, the mean provides a reliable and useful measure of central tendency.

Mr. Greene should use the mean temperature, which is 77.86°F, to summarize the temperatures for each day. The mean is a good measure of central tendency when the data set is approximately symmetric and has no significant outliers, which appears to be the case here. Additionally, using the mean will provide a single number that is representative of the entire data set. The interquartile range and mean absolute deviation are measures of spread and do not provide a summary of the temperatures for each day, and the maximum temperature is just one value and may not be representative of the entire data set.

Answer:

If (x-1) is a factor of the polynomial f(x) = 4x² - 4x² - x - K, then we know that (x-1) divides evenly into the polynomial, which means that the polynomial can be written as:

f(x) = (x-1)(ax + b)

where a and b are constants that we need to determine. We can use the distributive property to expand this expression and equate it with the original polynomial:

f(x) = (x-1)(ax + b) = 4x² - 4x - K

Expanding the left side of the equation, we get:

ax² + bx - ax - b = ax² - (a-b)x - b = 4x² - 4x - K

Now we can equate the coefficients of the like terms on both sides of the equation.

The coefficient of x^2 on the left side is a, and on the right side it is 4. Therefore, we have:

a = 4

The coefficient of x on the left side is b - a, and on the right side it is -4. Therefore, we have:

b - a = -4

Substituting a=4, we get:

b - 4 = -4

Solving for b, we get:

b = 0

So the polynomial can be written as:

f(x) = (x-1)(4x + 0) = 4x² - 4x

Therefore, K = 0.

To find the roots of the equation, we need to set f(x) = 0 and solve for x:

4x² - 4x = 0

Factor out 4x:

4x(x - 1) = 0

So the roots of the equation are x = 0 and x = 1.

Plan A lasts for 2/7 hours or approximately 17.14 minutes, and Plan B lasts for 9/7 hours or approximately 1 hour and 17.14 minutes.

In algebra, the definition of an equation in its simplest form is a mathematical statement that shows that two mathematical expressions are equal. For example, 3x 5 = 14 is an equation where 3x 5 and 14 are two expressions separated by an equal sign.

Let's say plan A takes x hours and plan B takes y hours.

Based on the given data, we can create two equations:

Monday: 6x + 5y = 7

Tuesday: 2x + 3y = 3

We can solve this system of equations by elimination or substitution.

Eliminating, we can multiply the second equation by two and subtract it from the first equation:

(6x + 5 y) - 2 (2x + 3y) = 7 - 2 (3)

Simplifying this, we get:

2x - y = 1

Using substitution, we can solve an equation in one variable and replace it with another equation:

From the first equation we can solve for x:  

6x + 5y = 7

6x = 7-5 years

x = (7-5 ​​years) / 6

Substituting this into the second equation, we get:

2 ((7-5 years) / 6) + 3 y = 3

Simplifying this, we get:

7 y = 9

y = 9/7

Now that we know y, we can substitute it back into both equations to solve for x:

6 x + 5 (9/7) = 7

Simplifying this, we get:

x = 2/7

Therefore, Plan A takes 2/7 hours, or approximately 17.14 minutes, and Plan B takes 9/7 hours, or approximately 1 hour and 17.14 minutes.

Answer: direction angle of c is pi/4.

Step-by-step explanation: We can find c by adding the corresponding components of a and b:

c = a + b = ⟨–7, 3⟩ + ⟨–2, –12⟩ = ⟨–9, –9⟩

To find the magnitude of c, we can use the formula:

|c| = sqrt(c1^2 + c2^2)

where c1 and c2 are the x- and y-components of c, respectively. In this case, we have:

|c| = sqrt((-9)^2 + (-9)^2) = sqrt(162) = 9sqrt(2)

To find the direction angle of c, we can use the formula:

theta = atan(c2 / c1)

where theta is the angle between the positive x-axis and the vector c. In this case, we have:

theta = atan((-9) / (-9)) = atan(1) = pi/4

So the direction angle of c is pi/4.

Therefore, the magnitude of c is 9sqrt(2) and the direction angle of c is pi/4.

the actual area of the base of the fountain, in square feet, after it is built is approximately 1.3 square feet (rounded to the nearest tenth of a square foot).

How to solve the question?

To find the actual area of the base of the fountain, we need to convert the measurements from the blueprint to the actual measurements.

First, we need to find the radius of the circular base. The diameter of the base is given as 40 centimeters on the blueprint, so the radius is half of that, or 20 centimeters.

Next, we need to convert the scale of the blueprint from centimeters to feet. The scale is given as three centimeters to four feet, which can be simplified to a ratio of 3:4. To convert from centimeters to feet, we need to multiply by a conversion factor of 1 foot/30.48 centimeters, since there are 30.48 centimeters in a foot.

So, to find the actual radius of the circular base in feet, we multiply the blueprint radius (20 centimeters) by the conversion factor:

20 centimeters * (1 foot/30.48 centimeters) = 0.656168 feet

Now that we have the actual radius of the circular base, we can find the actual area of the base. The formula for the area of a circle is A = πr^2, where A is the area and r is the radius. Plugging in the actual radius we just found, we get:

A = π(0.656168 feet)^2 = 1.34977 square feet

Therefore, the actual area of the base of the fountain, in square feet, after it is built is approximately 1.3 square feet (rounded to the nearest tenth of a square foot).

Therefore , the solution of the given problem of percentage comes out to be  14 gallons of the first brand and 56 gallons of the second brand must be utilised.

In statistics, a figure or metric than may be presented as a percentage or 100 is denoted by the abbreviation "a%". Another unusual spelling is "pct," "pct," and "pc." The percent symbol ("%") is the method that is most usually used for this. Additionally, there are no indications or predetermined ratios of any component to the whole. Numbers are effectively integers since they frequently add up to 100.

Here,

Let's write "x" for the first brand's (35% pure antifreeze) number of gallons and "y" for the second brand's (60% pure antifreeze) number of gallons.

Given:

70 gallons of mixture are required in total.

Desired antifreeze content in the combination is 55%

Based on the information provided, we can construct the following system of equations:

=> Equation 1: x + y = 70

=> Equation 2: 0.5*70 = 0.55x + 0.60y

=> x = 70 - y

=> 0.35(70 - y) + 0.60y = 0.55 * 70

=> 24.5 - 0.35y + 0.60y = 38.5

=> 0.25y = 14

=> y = 56

=> x = 70 - 56

=> x = 14

In order to get 70 gallons of a mixture that contains 55% pure antifreeze, 14 gallons of the first brand and 56 gallons of the second brand must be utilised.

Answer:

Step-by-step explanation:

The total amount Debra ended up paying for the equipment was $28,541.60 and the amount of interest Debra paid on the loan was $14,041.60

(a) To find the total amount Debra ended up paying for the equipment (including the down payment and monthly payments), we need to add the down payment to the total amount of the loan, and then add the total amount of the monthly payments made over the two years.

Total amount of the loan = $14,500 - $1,300 (down payment) = $13,200

Total amount paid = Down payment + Total amount of the loan + Total amount of monthly payments

Total amount paid = $1,300 + $13,200 + ($585.04 x 24) [since there are 24 monthly payments in 2 years]

Total amount paid = $1,300 + $13,200 + $14,041.60

Total amount paid = $28,541.60

Therefore, the total amount Debra ended up paying for the equipment (including the down payment and monthly payments) was $28,541.60.

(b) To find the amount of interest paid on the loan, we need to subtract the total amount borrowed from the total amount paid, and then subtract the down payment. This will give us the total amount of interest paid over the two years.

Total interest paid = Total amount paid - Total amount borrowed - Down payment

Total interest paid = $28,541.60 - $13,200 - $1,300

Total interest paid = $14,041.60

Therefore, the amount of interest Debra paid on the loan was $14,041.60.

The length of the rectangle is 10 inches and the width is 4 inches.

What is the area of the rectangle?

To find the area of a rectangle, we multiply the length of the rectangle by the width of the rectangle.

Let's assume that the width of the rectangle is "x" inches.

From the given information, we can write an equation for the length "L" in terms of the width "x":

L = 2x + 2

We also know that the area of the rectangle is 40 square inches:

A = L * x = 40

Substituting the expression for "L" in terms of "x" into the area equation, we get:

(2x + 2) * x = 40

Expanding the left-hand side of the equation and simplifying, we get:

2x² + 2x - 40 = 0

Dividing both sides by 2, we get:

x² + x - 20 = 0

This is a quadratic equation that can be factored:

(x + 5)(x - 4) = 0

The solutions are x = -5 and x = 4. Since the width of the rectangle cannot be negative, the only valid solution is:

x = 4

Substituting this value for "x" into the equation for "L", we get:

L = 2x + 2 = 2(4) + 2 = 10

Therefore, the length of the rectangle is 10 inches and the width is 4 inches.

There is a 0.9830, or 98.30%, probability that the mean clock life will exceed 12.5 years.

Probability is a metric used to express the possibility or chance that a particular event will occur.

Probabilities can be expressed as fractions from 0 to 1, as well as percentages from 0% to 100%.

Probability is simply the possibility that something will happen. When we don't know how something will turn out, we can talk about the possibility of one outcome or the likelihood of several.

The study of events that fit into a probability distribution is known as statistics.

So, the likelihood that the average clock life would exceed 12.5 years:

This is the p-value of Z when X = 12.5 subtracted by 1.

So,

Z = X - μ/σ

Z = 12.5 - 14/.07071

Z = -2.12

Z = The pvalue for -2.12 is 0.0170.

1 - 0.0170 = 0.9830

The likelihood that the mean clock life will be longer than 12.5 years is 0.9830, or 98.30%.

The maximum grazing area for the cow is approximately 53,343.08 square feet.

The maximum grazing area for the cow can be found by imagining a circle with radius equal to the length of the rope (130 feet) centered at the corner of the barn where the cow is tethered. The grazing area is the portion of the circle that lies outside the barn.

Since the barn is 8 feet by 8 feet, it covers a square area of 64 square feet. The radius of the circle is 130 feet, so the area of the circle is π(130)^2 square feet.

To find the maximum grazing area, we need to subtract the area of the barn from the area of the circle.

Area of circle = π(130)^2 square feet = 53,407.08 square feet

Area of barn = 64 square feet

Maximum grazing area = Area of circle - Area of barn

Answer:

The perpendicular bisector of a line segment AB is the line that passes through the midpoint of AB and is perpendicular to AB.

To find the equation of the perpendicular bisector of segment AB, we can follow these steps:

M = ( (x1 + x2)/2, (y1 + y2)/2 )

where A = (x1, y1) and B = (x2, y2).

M = ( (-6 + 14)/2, (4 - 12)/2 ) = (4, -4)

m = (y2 - y1) / (x2 - x1)

m = (-12 - 4) / (14 - (-6)) = -16/20 = -4/5

m_perp = -1/m

m_perp = -1/(-4/5) = 5/4

y - y1 = m(x - x1)

y - (-4) = (5/4)(x - 4)

Simplifying, we get:

y + 4 = (5/4)x - 5

(5/4)x - y - 9 = 0

So, the formula that expresses the fact that an arbitrary point P(x, y) is on the perpendicular bisector of segment AB is:

(5/4)x - y - 9 = 0
