The company will continue to produce the same quality of candy, and not be able to take advantage of the extra 2% production rate.

The p-value of 0.12 indicates that the null hypothesis (H0: p = 0.96) is not rejected, meaning that the machine is producing more than the required 96% high-quality candy. However, since the actual production rate of the machine is higher than the required rate, the false negative hypothesis (Ha: p > 0.96) is also not accepted. Thus, the company will not be able to make any changes to the machine to improve its performance, even though they could have if the p-value was lower than the predetermined α = 0.05. As a result, the company will continue to produce the same quality of candy, and not be able to take advantage of the extra 2% production rate.

What is fraction?

A fraction is a mathematical expression that represents a part of a whole or a division of one quantity by another. It consists of two numbers separated by a horizontal line called a fraction bar or a vinculum. The number above the fraction bar is called the numerator, and the number below the fraction bar is called the denominator. Fractions can be proper, improper, or mixed. A proper fraction has a numerator that is smaller than the denominator. An improper fraction has a numerator that is greater than or equal to the denominator. A mixed fraction consists of a whole number and a proper fraction.

Answer:

A. -(5y+2) + y = 5

Step-by-step explanation:

Solving the above Equation given to us in the Question,

-x + y = 5...... Equation 1

x - 5y = 2....... Equation 2

Step 1

We make x subject of the formula in Equation 2

---> x= 5y + 2

Step 2

This would be to substitute 5y + 2 for x in Equation 1

-x + y = 5...... Equation 1

-(5y+2) + y = 5

Hence, Option A is the correct option

The solution that satisfies the linear inequality in two variables 2x - 3y < 6 is: B. (2, -7)

To check if a solution satisfies the inequality, we can substitute the values of x and y into the inequality and see if the resulting statement is true. If it is true, then the solution satisfies the inequality.

A. (6,1)

In this case, if we substitute x = 6 and y = 1 into the inequality, we get:

2(6) - 3(1) < 6

12 - 3 < 6

9 < 6

This is not a true statement, so solution A does not satisfy the inequality.

If we check the other solutions, we find that only solution B satisfies the inequality:

2x - 3y < 6

2(2) - 3(-7) < 6

4 + 21 < 6

25 < 6

This is not a true statement, so solution B does not satisfy the inequality.

2x - 3y < 6

2(1) - 3(5) < 6

2 - 15 < 6

-13 < 6

This is a true statement, so solution C satisfies the inequality.

2x - 3y < 6

2(5) - 3(1) < 6

10 - 3 < 6

7 < 6

This is not a true statement, so solution D does not satisfy the inequality.

Answer:

300 pi, 942, or 942.477... cm^3

Step-by-step explanation:

The volume of a cone can be found using the following formula.

V= 1/3* pi* r^2* h

We know that the radius is 10 centimeters and the height is 9 centimeters.

r= 10 cm

h= 9 cm

V= 1/3* pi * (10 cm)^2 * 9 cm

First, evaluate the exponent.

(10 cm)^2= 10 cm * 10 cm = 100 cm^2

V= 1/3 * pi * 100 cm^2 * 9 cm

In terms of pi:

To solve in terms of pi, multiply all the terms that are not pi together

V= (1/3* 100 cm^2*9cm)*pi

V= (1/3* 900 cm^3)*pi

V= (300 cm^3)* pi

V= 300 pi cm^3

Using 3.14 as pi

V= 300 pi cm^3

Substitute 3.14 in for pi

V= (300*3.14) cm^3

V= 942 cm^3

Using 3.14159265.... as pi

V= 300 pi cm^3

Use the pi button for pi

V= 942.477796076938 cm^3

Notice that I divided it into two equations, i) and ii).

I'll isolate the variable X in equation i), look:

From now on, we will use this value when referring to X.

So, let's replace where's X in equation ii) by (-7 +3y):

At this moment we know the value of the variable Y as 2. So, we can choose any of the equations and replace this value.

Let's replace Y in the first equation now:

So, the solution of this system is x = -1 and y = 2.

Answer:

(-1, 2)

Step-by-step explanation:

x-3y = -7

3x+y = -1     <===== multiply this equation by 3 to get

9x + 3y = -3   <=====add this to first equation ( this will eliminate 'x')

10x = -10     so x = -1

  use this value of 'x 'in any of the equations to compute 'y'

      -1 -3y = -7      

           -3y = -6

              y =  2

The percent error in the experimental value of g is option (d) 2.04%. This means that the experimental value of g deviates from the accepted value by 2.04%.

To calculate the percent error, we need to compare the experimental value of g with the accepted value.

Let's assume the experimental value of g is ge and the accepted value is ga.

The formula for percent error is:

Percent Error = |(ge - ga) / ga| * 100

Substituting the given values:

Percent Error = |(ge - 9.8) / 9.8| * 100

We are given that the accepted value of g is 9.8 m/s^2.

Suppose the experimental value of g is 9.6 m/s^2.

Percent Error = |(9.6 - 9.8) / 9.8| * 100

Percent Error = |-0.2 / 9.8| * 100

Percent Error = 0.0204 * 100

Percent Error = 2.04%

The correct option from the given choices would be (d) 4%, which is the closest value to the calculated percent error.

Rounding to 2 decimal places, the missing side of the right triangle is approximately 15.62 units.

To find the missing side of a right triangle, we can use the Pythagorean theorem, which states that in a right triangle, the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.

In this case, we are given sides a = 10 and b = 12, and we need to find the missing side c.

Using the Pythagorean theorem:

c^2 = a^2 + b^2

Substituting the given values:

c^2 = 10^2 + 12^2

c^2 = 100 + 144

c^2 = 244

Taking the square root of both sides to solve for c:

c = √244

c ≈ 15.62

Rounding to 2 decimal places, the missing side of the right triangle is approximately 15.62 units.

Jasmine washes 42 windows in 2 hours.

To find the number of windows Jasmine can wash in 2 hours, we need to first calculate how many windows she washes per hour.

Jasmine washes 10 1/2 windows in 1/4 hour. To convert this to windows per hour, we can multiply by 4:

10 1/2 x 4 = 42 windows per hour

So, Jasmine can wash 42 windows per hour.

To find the number of windows she can wash in 2 hours, we simply need to multiply the number of windows she can wash per hour by the number of hours she will be working:

42 windows per hour x 2 hours = 84 windows

Therefore, Jasmine can wash 84 windows in 2 .

3 × 90 thus equals 280 degrees.

The figure moves onto the following quadrant of the graph with each 90 degree rotation. In order to shift Figure I to the location of Figure J, you must move the three figure quadrants in a clockwise direction. 3 × 90 thus equals 280 degrees. Only one transformation is needed.

Which transformation corresponds to turning a figure 90 degrees counterclockwise?

The coordinate transformation (x, y) (y, x) is equivalent to a rotation of the origin 90 degrees counterclockwise. The coordinate transformation (x, y) (x, y) is comparable to a 180 degree counterclockwise rotation of the origin.

Our point A(x,y) becomes A' when a point is rotated 90 degrees counterclockwise about the origin (-y,x). To put it another way, flip x and y, making y negative.

Shea needs to do 600 carpet cleaning per year to break even.

What is revenue?

Total revenue is the total amount of money earned by a business from the sale of its products or services during a particular period of time.

To break even, the total revenue Shea generates from the carpet cleaning business must be equal to the total cost of running the business.

Let's first calculate the total cost of running the business per year:

Total Cost = Fixed Costs + Variable Costs

Since the fixed plus variable costs per month total $1,500, the total cost per year would be:

Total Cost = $1,500 x 12

Total Cost = $18,000

Now, let's calculate the profit that Shea makes per cleaning:

Profit per Cleaning = Price per Cleaning - Cost per Cleaning

Profit per Cleaning = $60 - $30

Profit per Cleaning = $30

So, Shea makes a profit of $30 per cleaning.

To break even, the total profit generated by the number of cleanings Shea does per year should be equal to the total cost of running the business per year:

Total Profit = Total Revenue - Total Cost

If x is the number of carpet cleaning Shea needs to do per year to break even, then:

Total Revenue = Price per Cleaning x Number of Cleanings per Year = $60x

Total Profit = Profit per Cleaning x Number of Cleanings per Year = $30x

Setting Total Profit equal to Total Cost:

$30x = $18,000

x = $18,000 / $30

x = 600

Therefore, Shea needs to do 600 carpet cleaning per year to break even.

\(Answer: \large\boxed{Cos(\theta_{1} )=\frac{84}{85}}\)

Step-by-step explanation:

Thinking about a triangle in Quadrant IV, we can imagine sin as opposite/hypotenuse. Therefore, the hypotenuse is 85 and the opposite angle is -13. To find the adjacent angle, we use the pythagorean theorum,

\(a^2+b^2=c^2\)

\(-13^2+b^2=85^2\)

\(169+b^2=7225\)

\(b^2=7056\)

\(b=\sqrt{7056}\)

\(b=\pm84\)

Taking only the positive number, the adjacent angle is 84

Now that we have all 3 sides, we can find the cosine.

Cosine is adjacent/hypotenuse

Therefore,

\(Cos(\theta_{1} )=\frac{84}{85}\)

It will take a minimum of 10 clock hours (not driving hours) for the truck driver to travel 450 miles from Charlotte, NC to Pittsburgh, PA.

The current Hours of Service (HOS) rules for truck drivers stipulate that a truck driver cannot drive for more than 11 hours after 10 consecutive hours off duty.

Additionally, the driver is not allowed to drive beyond 14 hours after coming on duty.

The driver's shift includes both driving and non-driving time.

Therefore, it is necessary to consider the total amount of time spent on the job.

The truck driver will have to stop for rest breaks, refueling, or other reasons during the 450-mile journey to Pittsburgh, Pennsylvania. The driver is required to take a 30-minute break after eight hours of driving.

Therefore, the minimum number of clock hours (not driving hours) it will take the truck driver to travel the 450-mile distance from Charlotte, NC to Pittsburgh, PA is calculated as follows:

Time for the trip = (Distance ÷ Average Speed) + Breaks

Time for the trip = (450 ÷ 50) + (30 ÷ 60) × 2

Time for the trip = 9 + 1

Time for the trip = 10 clock hours

Therefore, it will take a minimum of 10 clock hours (not driving hours) for the truck driver to travel 450 miles from Charlotte, NC to Pittsburgh, PA.
