Final answer:

If the brackets in the expression “[-1.1]” are interpreted as the floor function, the value is “-2”, because the floor function always rounds a number down to the closest lesser whole number.

Explanation:

The question appears to be asking for the value of the mathematical expression “[-1.1]”. However, the notation is a bit unclear. If the brackets denote the floor function, which rounds a number down to the nearest whole number, then the value of “[-1.1]” is indeed “-2” because -1.1 is rounded down to -2.

The floor function basically chops off all decimal points and moves a number to the next lower integer if it's not already an integer. Hence, the correct answer based on the interpretation of the floor function is “-2”.

The equations representing Dory's and Nemo's lunch orders are 3x + 3y = 11.25 and 4x + 2y = 10, respectively.

Let's define the variables first. Let x be the cost of one soft taco, and y be the cost of one double decker.

Dory orders three soft tacos and three double deckers for $11.25. This gives us the first equation:

3x + 3y = 11.25

Nemo orders four soft tacos and two double deckers for $10. This gives us the second equation:

4x + 2y = 10

We now have a system of equations that represents the lunch orders:

3x + 3y = 11.25

4x + 2y = 10

These equations can be solved simultaneously to find the individual costs of the soft tacos and double deckers.

Final answer:

The sum of the deviations about the mean always equals zero because positive and negative deviations cancel out. This concept is essential for calculating variance and standard deviation in statistics.

Explanation:

The sum of the deviations about the mean always equals zero. When analysing a set of data, each data value has a deviation from the mean, which is the difference between the value and the mean. These deviations illustrate the spread of the data around the mean. Positive deviations occur when a data value is greater than the mean, while negative deviations occur when a data value is less than the mean.

If we sum all the deviations, the positive and negative values will cancel each other out, resulting in a sum of zero. This happens because the mean is the point where the total amount above it is equal to the total amount below it. This concept is core to understanding the calculation of other statistics such as variance and standard deviation, which provide measures of data spread. Variance is the mean of the squared deviations from the mean, and the standard deviation is the square root of the variance.

The fact that the sum of deviations equals zero is important when working with the Central Limit Theorem, as it assures that the mean of sample means will equal the population mean, assuming the sample size is sufficiently large.

Final answer:

A French dessert chef can make 30 portions of sorbet from 3 kilograms, with each portion weighing 1/10 of a kilogram, by simply dividing the total weight by the weight of one portion.

Explanation:

The subject of this question is Mathematics, specifically related to division and units of measurement. To find out how many portions each weighing 1/10 of a kilogram can be made from 3 kilograms of sorbet, we divide the total amount of sorbet by the weight of one portion. Therefore, we perform the division:

Determine the weight of one portion: 1/10 kg.

Divide the total weight of sorbet by the weight of one portion: 3 kg ÷ (1/10 kg).

The division gives us the result of 30 portions because 3 ÷ (1/10) is equivalent to 3 × 10.

So, a French dessert chef can create 30 portions of sorbet, with each portion weighing 1/10 of a kilogram.

The roots of the polynomial equation x²−12x−64=0 are 16 and -4. These roots are calculated using the quadratic formula and represent the points where the function intersects the x-axis. The importance of finding real roots in quadratic equations is significant in solving real-world problems.

Roots of Polynomial Equation

The roots or solutions of the polynomial equation x²−12x−64=0 can be calculated using quadratic formula. In general, the quadratic function is written as ax²+bx+c=0 and its roots are given by -b ± √(b² - 4ac) / 2a. In this case, a=1, b=-12 and c=-64.

Applying those values into the formula we get 12 ± √((-12)² - 4(1)(-64)) / 2(1) = 12 ± √(144 + 256) / 2 = 12 ± √400 / 2 = 12 ± 20 / 2. This gives us two possible roots: 16 and -4.

Graphically, these roots represent the x coordinates or points where the quadratic function intersects the x-axis on a two-dimensional graph. It is important to note that quadratic equations constructed on physical data always have real roots, which are important for solving real-world problems.

There are 14 dogs and 46 chickens on your uncle's farm.

To solve this problem, we can set up a system of equations. Let x be the number of dogs and y be the number of chickens on your uncle's farm.

The number of legs equation can be written as: 4x + 2y = 148 (since dogs have 4 legs and chickens have 2 legs).

The number of heads equation can be written as: x + y = 60 (since both dogs and chickens have 1 head).

We can solve this system of equations by substitution or elimination. Let's use elimination:

Multiplying the second equation by 2, we get 2x + 2y = 120.

Subtracting the new equation from the first equation, we can eliminate the 2y term: (4x + 2y) - (2x + 2y) = 148 - 120. Simplifying, we have 2x = 28.

Dividing both sides of the equation by 2, we find that x = 14. Substituting this value back into the second equation, we find that 14 + y = 60. Solving for y, we get y = 46.

Therefore, there are 14 dogs and 46 chickens on your uncle's farm.

Employee benefits, such as health insurance and retirement plans, add value to the total compensation received by workers. They account for about one-quarter of average hourly compensation, contributing to the overall attractiveness of the compensation package and promoting employee well-being and job satisfaction.

Employee benefits affect total employment compensation by adding to the overall value of the compensation package. They provide additional forms of remuneration beyond wages and salaries, such as health insurance, retirement plans, employer payments to Social Security, unemployment and worker's compensation insurance, and other benefits like Medicare.

These benefits contribute to the total compensation received by workers, accounting for about one-quarter of the average hourly compensation. So, for example, if a worker's wages are $20 per hour, the total compensation per hour might be around $26 when considering the value of benefits.

By providing employee benefits, employers aim to attract and retain talented employees, promote employee well-being, and enhance job satisfaction and productivity. These benefits play a crucial role in improving the overall compensation package and incentivizing employees to stay with the company.

Final answer:

Employee benefits, such as health insurance and retirement plans, greatly impact total employment compensation. These benefits, in addition to wages and salaries, make up the overall compensation received by workers.

Explanation:

Employee benefits have a significant impact on total employment compensation. These benefits include things like health insurance, retirement plans, employer payments to Social Security, and unemployment and worker's compensation insurance. When these benefits are added to wages and salaries, they make up the total compensation received by workers.

For example, if a worker's hourly wage is $20 and they receive $5 per hour in benefits, their total compensation per hour is $25. This means that employee benefits increase the overall value of compensation that workers receive.

Employee benefits are important for attracting and retaining employees, as well as promoting employee well-being and job satisfaction. They can also have an impact on the cost of labor for employers, as they must budget for these benefits in addition to wages and salaries.

Answer:

C. 1.1 seconds

Step-by-step explanation:

The formula to use is :

[tex]h=ut+\frac{1}{2}at^{2}[/tex]

Where: h is the height of 20 ft, u is the velocity of 2ft/s and a is the gravitational acceleration of 9.8m/s². The acceleration should be converted to ft/sec² to simplify calculations. The value is then 32.15ft/sec².

Substituting these values into the equation:

[tex]20=2t+0.5*32.15t^{2} \\20=2t+16.075t^{2} \\0=16.075t^{2}+2t-20[/tex]

Using the quadratic formula, t can be solved.

a = 16.075, b = 2, c = -20:

[tex]t=\frac{-b+-\sqrt{b^{2}-4ac} }{2a} \\t=\frac{-2+-\sqrt{2^{2}-4(16.075)(-20)} }{2(16.075)}\\t=\frac{-2+-35.92}{32.15}\\t=1.055 \\OR\\t=-1.179[/tex]

The answer cannot be negative, therefore the answer is t = 1.055 ≈ 1.1seconds
