you have sum([minutes of delay]) in your view. if aggregate measures is unchecked, what will the view show instead of sum([minutes of delay])?
Answers
It will show the individual values for each row in the view, rather than a sum of the values By time
When the aggregate measures option is unchecked, Tableau will display the individual values for each row in the view instead of totaling them up. This means that instead of showing the sum of the minutes of delay, the view will show the individual delay minutes for each row.
For example, if the view contains three rows with a delay of 10 minutes, 15 minutes and 20 minutes of time, the view will display 10, 15 and 20 instead of 45.

Standard Appliances obtains refrigerators for $1,620 less 26% and 6%. Standard's overhead is 17% of the selling price of $1,690. A scratched demonstrator unit from their floor display was cleared out for $1,345. a. What is the regular rate of markup on cost? % Round to two decimal places b. What is the rate of markdown on the demonstrator unit? % Round to two decimal places c. What is the operating profit or loss on the demostrator unit? Round to the nearest cent d. What is the rate of markup on cost that was actually realized? % Round to two decimal places
Answers
a. The regular rate of markup on cost is approximately 26%.
b. The rate of markdown on the demonstrator unit is approximately 20%.
c. The operating profit on the demonstrator unit is approximately $3.73.
d. The rate of markup on cost that was actually realized is approximately 0.28%.
a. To calculate the regular rate of markup on cost, we need to find the difference between the selling price and the cost, and then calculate the percentage markup based on the cost.
Let's denote the cost as C.
Selling price = Cost + Markup
$1,690 = C + (26% of C)
To find the cost:
$1,690 = C + 0.26C
$1,690 = 1.26C
C = $1,690 / 1.26
C ≈ $1,341.27
Markup on cost = Selling price - Cost
Markup on cost = $1,690 - $1,341.27
Markup on cost ≈ $348.73
Rate of markup on cost = (Markup on cost / Cost) * 100
Rate of markup on cost = ($348.73 / $1,341.27) * 100
Rate of markup on cost ≈ 26%
The regular rate of markup on cost is approximately 26%.
b. The rate of markdown on the demonstrator unit can be calculated by finding the difference between the original selling price and the clearance price, and then calculating the percentage markdown based on the original selling price.
Original selling price = $1,690
Clearance price = $1,345
Markdown = Original selling price - Clearance price
Markdown = $1,690 - $1,345
Markdown = $345
Rate of markdown on the demonstrator unit = (Markdown / Original selling price) * 100
Rate of markdown on the demonstrator unit = ($345 / $1,690) * 100
Rate of markdown on the demonstrator unit ≈ 20%
The rate of markdown on the demonstrator unit is approximately 20%.
c. Operating profit or loss on the demonstrator unit can be calculated by finding the difference between the clearance price and the cost.
Cost = $1,341.27
Clearance price = $1,345
Operating profit or loss = Clearance price - Cost
Operating profit or loss = $1,345 - $1,341.27
Operating profit or loss ≈ $3.73
The operating profit on the demonstrator unit is approximately $3.73.
d. The rate of markup on cost that was actually realized can be calculated by finding the difference between the actual selling price (clearance price) and the cost, and then calculating the percentage markup based on the cost.
Actual selling price (clearance price) = $1,345
Cost = $1,341.27
Markup on cost that was actually realized = Actual selling price - Cost
Markup on cost that was actually realized = $1,345 - $1,341.27
Markup on cost that was actually realized ≈ $3.73
Rate of markup on cost that was actually realized = (Markup on cost that was actually realized / Cost) * 100
Rate of markup on cost that was actually realized = ($3.73 / $1,341.27) * 100
Rate of markup on cost that was actually realized ≈ 0.2781% ≈ 0.28%
The rate of markup on cost that was actually realized is approximately 0.28%.

If Jenna's score had improved by the same amount as the class average, her retake score would be 75 (65 + 10). However, Jenna's actual retake score was 80, which is 5 points higher than what she would have scored if she had improved by the same amount as the rest of the class.

The p-value is less than our chosen level of significance (usually 0.05), we would reject the null hypothesis and conclude that there is a significant difference in handedness between men and women.
To test the null hypothesis that there's no difference in handedness between men and women, we should use the Chi-Square test for Independence. This test is used to determine if there is a significant association between two categorical variables, in this case, the gender and handedness of the students.
The table provided in the question shows the counts of students in each gender and handedness category. To perform the Chi-Square test for Independence, we would calculate the expected counts under the null hypothesis of no association, and then calculate the test statistic and p-value. If the p-value is less than our chosen level of significance (usually 0.05), we would reject the null hypothesis and conclude that there is a significant difference in handedness between men and women.

3. The number of boys in a class are 36, and the ratio
of the boys and girls in the class is 2 : 3. Find the
total number of students in the class.
Answers
There are 37 students in the class.
Let's use b to represent the number of boys in the class and g to represent the number of girls in the class. We know that there are 36 boys in the class and that the ratio of boys to girls is 2:3, so we can write:
b/g = 2/3
Multiplying both sides by 3g gives us:
b = (2/3)g
We can use this expression for b to substitute into the total number of students in the class. The total number of students in the class is:
b + g = 36 + g
Substituting b = (2/3)g gives:
(2/3)g + g = 36 + g
(5/3)g = 36
g = 21.6
However, we can't have a fraction of a student, so let's round g up to the nearest whole number:
g = 22
Substituting g = 22 into b/g = 2/3 gives:
b = (2/3)g
b = (2/3)(22)
b = 14.67
Again, we can't have a fraction of a student, so let's round b up to the nearest whole number:
b = 15
Therefore, there are 15 boys and 22 girls in the class, for a total of:
15 + 22 = 37

Let's break down the steps:
1. Identify the sides and angles given in the triangle: RS = 4m, ST = 4.7m, and LR = 57°.
2. Apply the triangle inequality theorem to check if the given sides satisfy the condition for forming a triangle. The sum of any two sides must be greater than the third side.
RS + ST > RT
RS + RT > ST
ST + RT > RS
Plug in the given values:
4 + 4.7 > RT
4 + RT > 4.7
4.7 + RT > 4
Simplify the inequalities:
8.7 > RT
RT > 0.3
5.7 + RT > 4
3. Based on the inequalities, we can determine the range of possible values for RT. Since RT must be greater than 0.3 and less than 8.7, we have:
0.3 < RT < 8.7
4. To find the number of unique triangles, we need to determine the range of possible values for the angle LR. Since it is given as 57°, there is no variability in the angle measurement.
5. The number of unique triangles can be determined by calculating the number of values within the valid range of RT (0.3 < RT < 8.7). This range represents the possible lengths of the third side of the triangle.
So the number of unique triangles is determined by the number of valid RT values within the range of 0.3 to 8.7.
Please note that to determine the specific number of unique triangles, we would need more information about the angle measures or side lengths in addition to the given data.

Answers
Answer: y = -3/5x - 6
Step-by-step explanation:
There are a few equations that can be used for this, but the simplest one would be y = mx + b
We are given:
y = -3
m = -3/5 (slope)
x = -5
b = ?
Our equation is this, we are solving for b
==> -3 = -3/5 ( -5) + b
==> -3 = -3/5 ( -5) + b ( multiply the brackets)
==> -3 = 3 + b ( subtract 3 to both sides)
==> -6 = b
Now we can make the desired equation in slope intercept form;
y = -3/5x - 6

Truman is buying a teddy bear and flowers for his girIfriend. Flowers Galore charges $13 for the teddy bear and $0. 75 per flower. Famous Florist charges $9 for the teddy bear and $1. 25 per flower. Which inequality represents the number of flowers, f, Truman would need to buy to make Flowers Galore the cheaper option?
Answers
The inequality represents the number of flowers, Truman would buy at Flowers Galore is f < 8.
Price of teddy bear = $13
Price of the flower = $0. 75
Florist charges the price of a teddy bear = $13
The florist charges the price of the flower = $1.25
Assume that number of flowers Truman buys = f
The total cost of purchasing teddy bears and flowers at Flowers Galore =
C1 = 13 + 0.75f
The total cost of purchasing teddy bears and flowers at Famous Florist is C2 = 9 + 1.25f
The inequality for Flowers Galore can be written as:
C1 < C2
13 + 0.75f < 9 + 1.25f
0.5f < 4
Dividing on both sides by 0.5,
f < 8
Therefore, we can conclude that the inequality represents the number of flowers, Truman would buy is f < 8.

Answers
The correct sampling method described in the question is a stratified random sample among the simple random sample, stratified random sample, cluster random sample and Voluntary random sample
The sampling method described in the question is a stratified random sample.
In a stratified random sample, the population is divided into subgroups or strata based on certain characteristics or criteria. Then, a random sample is selected from each stratum. The key idea behind this method is to ensure that each subgroup is represented in the sample proportionally to its size or importance in the population. This helps to provide a more accurate representation of the entire population.
In the given sampling method, the population is divided into subgroups, and a fixed number of units is taken from each group. This aligns with the process of a stratified random sample. The sample selection is random within each subgroup, but the number of units taken from each group is fixed.
Other sampling methods mentioned in the question are:
Simple random sample: In a simple random sample, each unit in the population has an equal chance of being selected. This method does not involve dividing the population into subgroups.
Cluster random sample: In a cluster random sample, the population is divided into clusters or groups, and a random selection of clusters is included in the sample. Within the selected clusters, all units are included in the sample.
Voluntary random sample: In a voluntary random sample, individuals self-select to participate in the sample. This method can introduce bias as those who choose to participate may have different characteristics than those who do not.
Therefore, the correct sampling method described in the question is a stratified random sample.
