Answer:

The missing fraction is 6/12

(you can further simplify this but the question requires that you don't do that)

Step-by-step explanation:

To add fractions easily, their denominators should have the same value, so the denominator should be 12,

Then, to get 16 in the numerator, we need to find a number that on adding to 10, gives 16, or,

10 + x = 16

x = 16 - 10

x = 6

So, the numerator should be 6

so we get the fraction, 6/12

We can also solve it in an alternate way,

\(10/12 + x = 16/12\\x = 16/12 - 10/12\\x = (16-10)/12\\x = 6/12\)

You have a total of six different ways to select a snack and a beverage at the amusement park.

To determine the number of different ways you can select a snack and a beverage, we can use the concept of combinations.

Let's analyze the options:

Snack: You can choose either a chili dog or popcorn. This gives us 2 choices for the snack.

Beverage: You can choose either lemonade, an energy drink, or water. This gives us 3 choices for the beverage.

To calculate the total number of combinations, we multiply the number of choices for the snack by the number of choices for the beverage. Therefore, the number of different ways to select a snack and a beverage is 2 (choices for snack) multiplied by 3 (choices for beverage), which equals 6.

In other words, there are six different combinations possible:

Chili dog and lemonade

Chili dog and energy drink

Chili dog and water

Popcorn and lemonade

Popcorn and energy drink

Popcorn and water

So, when considering all the options, you have a total of six different ways to select a snack and a beverage at the amusement park.

The triangle with side lengths of  48 in., 56 in., and 83 in.  is obtuse, because 832> 48² +56²

A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry. A triangle with vertices A, B, and C is denoted \triangle ABC. In Euclidean geometry, any three points, when non-collinear, determine a unique triangle and simultaneously, a unique plane.

here, we have,

The side lengths of the triangles are 48 in., 56 in., and 83 in

The smallest side lengths are: 48 in., 56 in

The sum of the squares of these side lengths is

48^2+ 56^2

For the triangle to be obtuse, then the following must be true

83^2> 48² +56²

Evaluate the exponents

Given that a company's vice president's salary n years after becoming vice president is defined by the formula S(n) = 70000(1.2)". We have to determine which of the following statements is true:

Given that a company's vice president's salary n years after becoming vice president is defined by the formula S(n) = 70000(1.2)". We have to determine which of the following statements is true:

She will be receiving a 2% raise per year. Her salary will increase $14,000 every year. The percent increase of her salary is 120% every year. Her salary is always 0.2 times the previous year's salary. The percent increase of her salary is 20% every year.

To calculate the salary of the vice president after n years of becoming a vice president, we use the given formula:

S(n) = 70000(1.2)

S(n) = 84000

The salary of the vice president after one year of becoming a vice president: S(1) = 70000(1.2)

S(1) = 84000

The percent increase of her salary is: S(n) = 70000(1.2)n

S(n) - S(n-1) / S(n-1) × 100%

S(n) - S(n-1) / S(n-1) × 100% = (70000(1.2)n) - (70000(1.2)n-1) / (70000(1.2)n-1) × 100%

S(n) - S(n-1) / S(n-1) × 100% = 20%

Therefore, the correct statement is the percent increase of her salary is 20% every year. Hence, the answer is option E.

To solve the system of equations using elimination, we'll eliminate one variable by manipulating the equations.

Let's follow the steps: Given equations: 3x + 2y = -3. 9x + 4y = 3. To eliminate the y variable, we can multiply equation (1) by 2 and equation (2) by -1, which will allow us to add the two equations together: 2(3x + 2y) = 2(-3). -1(9x + 4y) = -1(3). Simplifying the equations: 6x + 4y = -6. -9x - 4y = -3. Now, let's add the two equations together: (6x + 4y) + (-9x - 4y) = -6 + (-3). Simplifying the equation: -3x = -9. Dividing both sides by -3: x = 3. Now that we have the value of x, we can substitute it back into one of the original equations to solve for y. Let's use equation (1): 3(3) + 2y = -3. 9 + 2y = -3. Subtracting 9 from both sides: 2y = -12.  Dividing both sides by 2: y = -6. Therefore, the solution to the system of equations is x = 3 and y = -6.

The solutions of system of equations can be represented as the ordered pair (x, y) = (3, -6).

Answer:

Step-by-step explanation:

Component 3 must be started on day 197 to meet the delivery date of day 200.

To illustrate the backward schedule, we need to start from the delivery date (day 200) and work our way backward, taking into account the lead times and dependencies of each operation.

(a) Backward schedule:

Operation    |  Work Center  |  Time (hours)  |  Start Day

--------------------------------------------------------

Final Assembly |   Work Center 1  |        1       |     200

Sub-assembly 1 |   Work Center 2  |        2       |     199

Component 4     |   Work Center 3  |        3       |     197

Component 2     |   Work Center 4  |        4       |     196

Component 3     |   Work Center 5  |        3       |     ????

(b) To identify when component 3 must be started to meet the delivery date, we need to consider its dependencies and lead times.

From the backward schedule, we see that component 3 is required for sub-assembly 1, which is scheduled to start on day 199. The time required for sub-assembly 1 is 2 hours, which means it should be completed by the end of day 199.

Since component 3 is needed for sub-assembly 1, we can conclude that component 3 must be started at least 2 hours before the start of sub-assembly 1. Therefore, component 3 should be started on day 199 - 2 = 197 to ensure it is completed and ready for sub-assembly 1.

Hence, component 3 must be started on day 197 to meet the delivery date of day 200.

Yes, it is true that an OLS (ordinary least squares) estimator meets all three small sample properties (unbiasedness, efficiency, and minimum variance) under certain conditions, in addition to being consistent.

These conditions include the assumption that the error term has a zero mean and constant variance, and that the errors are independent and identically distributed (IID). When these assumptions hold, the OLS estimator is considered to be BLUE (Best Linear Unbiased Estimator) and is a reliable tool for estimating the unknown parameters in a linear regression model. However, it is important to note that these assumptions may not always hold in practice, and alternative estimation methods may need to be considered.

The volume of the solid generated by revolving the region bounded by y = 2x, y=0, x=0, and x = 2 about the x-axis is 16π cubic units. Substituting the given boundaries, we have: V = π∫[0, 2] (2x)^2 dx

To solve this problem, we can use the formula for the volume of a solid generated by revolving a region bounded by two functions: V = π∫[a, b] (f(x))^2 dx.

Integrating, we get: V = π∫[0, 2] 4x^2 dx = 16π cubic units. We are to find the volume of the solid generated by revolving the region bounded by y = 2x, y=0, x=0, and x = 2 about the x-axis. Let's consider the region bounded by y = 2x, y=0, x=0, and x = 2. The axis of revolution is x-axis. Hence the method of cylindrical shells is used to find the volume of the solid. Let's take an elemental strip of width dx at a distance x from the y-axis.

The strip will have a thickness of y (= 2x) and a height equal to the length of the circumference of the shell formed at this point on revolution. Volume of the cylindrical shell = Circumference of the shell × Thickness of the shell × Height of the shell: Circumference of the shell = 2π Radius of the shell: Thickness of the shell = dx Height of the shell = y = 2x∴ Volume of the shell = 2π(x)(2x)dx= 4πx²dx∴.

Volume of the solid generated by revolving the region bounded by y = 2x, y=0, x=0, and x = 2 about the x-axis= ∫04 πx²dx= [4πx³/3]0²= 32π/3. The volume of the solid generated is 32π/3 cubic units.

The system of equations -x + 4y = -2 and 2x - y = 4 has a unique solution, where x = 2 and y = 0.


To determine the solution to the given system of equations, we can use various methods such as substitution or elimination. By solving the system using elimination, we can eliminate one variable by adding or subtracting the equations.

Multiplying the second equation by 4, we get 8x - 4y = 16. Now, we can add the modified second equation to the first equation:

(-x + 4y) + (8x - 4y) = -2 + 16
7x = 14
x = 2

Substituting x = 2 into the first equation, we have -2 + 4y = -2, which simplifies to 4y = 0. Solving for y gives y = 0.
