A team of researchers is testing the hypothesis that taking a break every hour to do 1 minute of
physical activity can reduce stress. They randomized 100 full-time employees between a
treatment group and a control group. The treatment group was instructed to take a 1-minute
break every hour at work to do some sort of physical activity. At the beginning and end of the
study, each participant took the Psychological Strain Questionnaire (PSQ), which measures
stress at work. The higher the PSQ score, the less stress the employee feels.
Researchers found that the change in PSQ scores for the treatment group was 10 points higher
than the change in PSQ scores for the control group. To test whether the results could be
explained by random chance, the researchers performed a simulation analysis. The summary of
2000 re-randomizations of their data is recorded below.

Answer:

B. {x| x = –7, –6, 2, 11, 3}

Step-by-step explanation:

The domain of the relation is {x | x = –5, –3, 1, 2, 6}. Therefore, the correct option is A.

The given ordered pairs are (-6, 0), (2, 1), (-7, -4), (11, 2) and (3, 2).

We need to find what is the domain of the relation.

The domain of a function is the set of values that we are allowed to plug into our function. This set is the x values in a function such as f(x). The range of a function is the set of values that the function assumes. This set is the values that the function shoots out after we plug an x value in.

Consider the provided diagram.

Here the left side represents the input (x) values and the right side represents the output (y) values.

The domain refers to the set of possible input values.

Now consider the provided figure, the set of the input values is:

{x | x = –5, –3, 1, 2, 6}.

The domain of the relation is {x | x = –5, –3, 1, 2, 6}. Therefore, the correct option is A.

Fallacies of relevance are types of logical fallacies that occur when an argument is presented without a relevant connection to the subject matter.

Rather than addressing the topic, these fallacies are aimed at the listener's feelings, emotions, or biases.There are many different types of fallacies of relevance, but some of the most common are ad hominem, straw man, appeal to authority, and red herring. Ad hominem, for example, is a type of fallacy that attacks the speaker rather than addressing the argument they are presenting.. It can undermine the quality of your argument and make you seem less credible.

However, if you want to describe a time when you used these fallacies, you might think back to a situation where you were arguing with someone and felt like you were losing the argument. In this case, you might have resorted to a fallacy of relevance to try to regain control of the conversation. In conclusion, it is important to avoid using fallacies of relevance in your arguments. Instead, focus on addressing the topic at hand and presenting logical, evidence-based arguments.

Answer: 18 units long

Step-by-step explanation:

In the diagram, it looks like line segment AW is 6 units long and WB is 12 units long. Because of parts-whole postulate (the whole is equal to the sum of its parts), you can add AW and WB's lengths together. 6 + 12 = 18, so the length of line segment AB is 18 units long.

Explanation:

Here, we want to solve the given inequality

We proceed as follows:

The surface area, A, is changing at a rate of 288 km/min decreasing.

Given,

Base length, l = 6 km

Height, h = 10 km

dl/dt = -9 km/min

dh/dt = 12 km/min

Surface area of a prism, A = 2 × (lw + lh + wh)

For a square prism,

Length, l = width, w = 6km

A = 2 × (l² + lh + lh)

= 2(l²) + 4lh

A = 2(l²) + 4 lh

= 2 × (l² + 2lh)

dA/dt = 2 × (2I × dI/dt + 0 × dh/dt + 2 × 2h × dl/dt + 2l × dh/dt)

dA/dt = 2 × (2l × dl/dt + 0 + 2 × 2h × dl/dt + 2l × dh/dt)

= 2 × (2(6) × (-9) + 2(10) × (-9) + 2(6) × (12))

= 2 × (- 108 + -180 + 144)

= 2 × -144

= -288 km/min

The rate of change of the surface area, A is decreasing by 288 km/min.

Leaving the TV on for two weeks while on vacation would cost you approximately $4.46.

To calculate the cost, we need to determine the total energy consumed by the TV while you were on vacation and then convert it to dollars.

First, let's calculate the energy consumption in kilowatt-hours (kWh):

Power (in kilowatts) = Voltage (in volts) * Current (in amps) / 1000

Power = 120 V * 0.96 A / 1000 = 0.1152 kW

Now, we need to find the total energy consumed in kilowatt-hours (kWh) over the two-week period:

Energy (in kilowatt-hours) = Power (in kilowatts) * Time (in hours)

Energy = 0.1152 kW * 24 hours/day * 14 days = 38.4512 kWh

Next, let's calculate the cost of this energy consumption:

Cost = Energy (in kilowatt-hours) * Cost per kilowatt-hour

Cost = 38.4512 kWh * $0.116/kWh = $4.46 (rounded to two decimal places)

Therefore, leaving the TV on for two weeks while on vacation would cost you approximately $4.46.

Answer:

The amount she saves is 25% of her income

Step-by-step explanation:

She is paid $11 per hour

She works 9 hours per day

and for 24 days per month

So, she works 9(24) hours per month

= 216 hours per month

Now, she is paid $11 hourly, so for 216 hours,

she will have 11(216) = $2376

Total income = $2376 per month

Saving = $594 per month

As a percentage, we divide the savings by the total income,

savings/(total income) = 594/2376 = 1/4 = 0.25

Hence we get 25%

Convert USD to THB, multiply amount of USD by the current exchange rate between USD and THB, which can be found on financial news or currency exchange websites, to get the equivalent amount in THB.

To convert US dollars (USD) to Thai baht (THB), you need to use the current exchange rate between the two currencies. Here are the steps to convert USD to THB:

Find the current exchange rate between USD and THB. This information can be found on financial news websites, currency exchange websites, or by contacting a bank or currency exchange service.

Multiply the amount of US dollars you want to convert by the current exchange rate to get the equivalent amount in Thai baht. For example, if the current exchange rate is 1 USD = 31.50 THB and you want to convert 100 USD to THB, the calculation would be:

100 USD x 31.50 THB/USD = 3,150 THB

Therefore, 100 USD is equal to 3,150 THB.

Note: The exchange rate between USD and THB can fluctuate over time, so make sure to use the current exchange rate for the most accurate conversion.

Using a bond calculator or formula, we can estimate that the present value of your bond's future cash flows is approximately $1,415. This means that the approximate market value of your bond is around $1,415, which is lower than the face value of $1,500.

To calculate the approximate market value of your bond, we need to consider the current interest rate environment. Since new corporate bonds are paying 8% interest, it means that the market interest rate has gone up since you purchased your bond with an interest rate of 5.5%. As a result, the value of your bond has decreased.

To get a detailed estimate of the market value of your bond, we would need to know the exact term and remaining term of the bond. However, as a general rule, we can estimate the approximate market value by calculating the present value of the bond's future cash flows.

This means that the approximate market value of your bond is around $1,415, which is lower than the face value of $1,500.

Please note that this is an estimate and the actual market value may vary based on several factors such as credit risk, liquidity, and demand in the market.

Well, to find 'per fluent ounce', we are measuring apple juice. So, to measure 1 fluid ounce is a bit difficult, so if we did it with a standard liquid measuring cup, there wouldn't typically be a line that denotes 1/8 of a cup. Therefore, it's best to use measuring spoons, such as a teaspoon or tablespoon when measuring 1 fluid ounce. So, how much is 1 fluent ounce? Well, there are 0.0625 US Pints in 1 US Fluid Ounce. But, for an pint, there are 16 fluent ounces in it. So, how much is 38 fluent ounces? Well, for 38 fluent ounces, we would have 4.75 US cups. So, that means we would have 608 ( 38 x 16 ) fluent ounces for 38 fluid ounces, so to answer your question, you should know how many ounces in a pint, and multiply that by whatever you need.

When on a stem and leaf plot and it does not show a number on the right side and only on the right side, the number on the right side would be zero.

A stem and leaf plot is a method of organizing numerical data into groups. It is a visual representation of a dataset in which each value is separated into a stem and a leaf. A stem is the left-hand digit(s) of the value, while a leaf is the right-hand digit(s).

The stem and leaf plot contains two columns, one for the stem and the other for the leaf. The stem values are arranged vertically in the left-hand column, and the leaf values are arranged horizontally in the right-hand column. The leaf column should be read from left to right to extract the values.

When a value appears multiple times, its leaves are stacked on top of one another. The stem and leaf plot is an effective method for representing data, particularly when dealing with large datasets.

Hence, If a stem and leaf plot displays a number only on the left side and not on the right side, then the number on the right side would be interpreted as zero.

The minimum sales price Zion Sun Chairs must sell each chair to earn a monthly profit of $75,000, given total monthly fixed costs of $17,363.50 and variable cost per chair of $52.17, is D. $78.01.

To compute the minimum sales price, we determine the expected total sales revenue to meet the target profit.

The total sales revenue equals the total costs and the target profit.

Using division operation, the sales price is the quotient of the total sales revenue and the number of units.

The number of beach chairs produced monthly = 3,575

Target monthly profit = $75,000

Total monthly fixed costs = $17,363.50

Variable cost per chair = $52.17

Total variable costs = $186,507.75 ($52.17 x 3,575)

Total costs (variable and fixed) = $203,871.25 ($186,507.75 + $17,363.50)

Expected total sales revenue to earn a profit = $278,871.25 ($203,871.25 + $75,000)

Selling price per unit to earn a profit of $75,000 = $78.01 ($278,871.25 ÷ 3,575)

Based on the given confidence interval alone, we cannot reasonably claim that model B plane flies farther than model A plane. The interval suggests that there is a range of possible differences, and the true difference could be positive, negative, or even zero.

Based on the given confidence interval for the mean difference in flight distance (B - A), which is -11.08 to 91.08 inches, we can analyze whether it is reasonable to claim that model B plane flies farther than model A plane.

Since the confidence interval includes both positive and negative values, it indicates that the true mean difference in flight distance could be anywhere within that range. In other words, there is uncertainty about the actual difference in flight distance between the two models.

To determine if it is reasonable to claim that model B plane flies farther than model A plane, we can examine if the interval contains only positive values. If the entire interval were above zero, it would strongly suggest that model B plane indeed flies farther. However, since the interval contains both negative and positive values, we cannot make a definitive conclusion.

Based on the given confidence interval alone, we cannot reasonably claim that model B plane flies farther than model A plane. The interval suggests that there is a range of possible differences, and the true difference could be positive, negative, or even zero. Further analysis or additional evidence would be needed to make a conclusive statement.
