a data analyst creates a scatterplot. the analyst wants to put a text label on the plot to call out specific data points. what function does the analyst use?
Answers
The analyst should use the alpha aesthetic. The alpha aesthetic makes some points on a plot more transparent than others to call out specific data points.
What is scatterplot?A set of points plotted on a horizontal and vertical axis is known as a scatter plot. Because they can demonstrate the degree of correlation, if any, between the values of observed quantities or phenomena, scatter plots are crucial in statistics (called variables). In an effort to demonstrate the degree to which one variable is influenced by another, scatter plots are used to plot data points on a horizontal and vertical axis. The values of the columns set on the X and Y axes determine the position of the marker that represents each row in the data table.

A. Transform F using the rule (x, y) → (-x, y) (1 pt.)
B. Describe the transformation precisely. (1 pt.)
C. Does the transformation result in a a congruent figure? (1 pt.)
Answers
A. To transform F using the rule (x, y) → (-x, y), we simply take the opposite of the x-coordinate of each point in F while leaving the y-coordinate unchanged. For example, if F has a point (2,3), after transformation, it becomes (-2,3). We do this for all points in F to get the transformed figure.
C. The transformation does result in a congruent figure. A congruent figure is one that has the same shape and size as the original figure but may be in a different position. In this case, the shape of the figure remains the same, and the transformation only changes the position of each point by reflecting it across the y-axis. Therefore, the resulting figure is congruent to the original figure.
A. To transform figure F using the rule (x, y) → (-x, y), you need to change the x-coordinates of all the points in the figure by taking their opposite value while keeping the y-coordinates the same. This transformation reflects the figure over the y-axis.
C. This transformation results in a congruent figure. Congruent figures have the same shape and size but may have different orientations. In this case, the transformation only changes the orientation of the figure by reflecting it across the y-axis, without altering its shape or size. Therefore, the original figure and its transformed counterpart are congruent.

It costs $4.25 per game at the bowling alley plus $1.90 to rent shoes. If Wayne has $20 how many games can he bowl?
Your response will be a number only.
Answers
The number of games Wayne can play is 4.
How many games can he bowl?A linear equation is an equation that when graphed is a straight line. A linear equation has a single variable that is raised to the power of one.
The total cost of the game is a function of the cost per game, number of games he can play and the cost of renting shoes
Total cost = cost to rent shoes + (cost per game x number of games)
$20 = $1.90 + ($4.25 x g)
$20 = $1.90 + $4.25g
In order to determine the value of g, take the following steps:
Combine similar terms: 20 - 1.90 = 4.25g
Add similar terms: 18.10 = 4.25g
Divide both sides by 4.25: 18.10 / 4.25

Answer:
a) 2 new printers
b) 11 min
Step-by-step explanation:
Given:
5 old printers take 30 min to produce a batch of comic books
4 new printers take 18 min to produce a batch of comic books
.
a) First, we need to find how long does one old and new printer take to produce a batch of comic books:
.
Since 5 old printers take 30 min to do the job, one printer would take 5 times more than this (5 printers work together and they do the job faster than one, that's why we have to multiply):
.
1 old printer does the job in:
5 × 30 = 150 min
1 new printer does the job in:
4 × 18 = 72 min
.
Since one old printer does the job in 150 min, 6 old printers would do this job 6 times faster (that's why we divide):
6 old printers would take:
150 / 6 = 25 min
2 new printers would take:
72 / 2 = 36 min
.
25 < 36
That means, 2 new printers would do this job faster

13. If you buy 31 floops, the total cost will be less than 40$. But if you buy 32 floops, the total cost will be more than 41$. Assuming these prices do not involve tax, what is the cost of one floop?
Answers
12. If the first two terms of the sequence are -3 and 9, the next few terms are
-3 + 9 = 6
9 + 6 = 15
6 + 15 = 21
15 + 21 = 36
and so on. Continuing in this way, you'd find the 16th term to be 4359.
13. Let x be the cost of 1 floop.
31 floops cost less than $40, so 31x < 40 or x < 40/31.
32 floops cost more than $41, so 32x > 41 or x > 41/32.
Equivalently,
41/32 < x < 40/31
and
41/32 ≈ 1.28125
40/31 ≈ 1.29032

Answers
When the given equations are added together, the overall equation can be summarized as follows: the combination of ethylene (C₂H₄) and hydrogen gas (H₂) yields ethane (C₂H₆), along with the formation of ethylene (C₂H₄) and ethene (C₂H₅).
The overall equation can be understood by examining the individual reactions and their products. In the first equation, ethylene (C₂H₄) reacts with hydrogen gas (H₂) to form ethane (C₂H₆). This equation represents the addition of hydrogen molecules to the double bond in ethylene, resulting in the formation of a single bond between the carbon atoms and the saturation of all available bonds.
The second equation involves the combination of hydrogen gas (H₂) with ethylene (C₂H₄) and the subsequent formation of ethene (C₂H₅) and ethane (C₂H₆). In this reaction, one of the hydrogen molecules adds to the double bond in ethylene, resulting in the formation of ethene.
The final equation depicts the combination of ethylene (C₂H₄) and ethane (C₂H₅) with hydrogen gas (H₂). This reaction leads to the formation of ethane (C₂H₆) and ethene (C₂H₅). Overall, when these equations are added together, they represent a series of reactions involving the addition and rearrangement of hydrogen atoms in hydrocarbon molecules, resulting in the formation of ethane and ethene.

the burning times of scented candles, in minutes, are normally distributed with a mean of 249 minutes and a standard deviation of 20 minutes. find the number of minutes a scented candle lasts if it burns out sooner than 80% of all scented candles. use excel, and round your answer to two decimal places.
Answers
The number of minutes a scented candle lasts if it burns out sooner than 80% of all scented candles is 244 minutes.
When the distribution is normal, we use the z-score formula.
In a set with mean µ and standard deviation σ , the z-score of a measure X is given by:
Z = (X – µ) / σ
What is Z-score?The Z-score shows how many standard deviations the measure is from the mean. After finding the Z-score, need to look at the z-score table and discover the p-value associated with the z-score. This p-value is the probability that the value of the measure is smaller than X, means, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
So, in this case, given that:
µ = 249, σ = 20
The number of minutes a scented candle lasts if it burns out sooner than 80% of all scented candles:
100 – 80 = 20th percentile, which is X when Z has a p-value of 0.2. So, X when Z = –0.253.
Now, put all the values into the formula:
Z = (X – µ) / σ
–0.253 = (X – 249) / 20
X – 249 = –0.253 * 20
X = 244
Hence, the candle burns for 244 minutes.

A random sample of Democrats and Republicans were asked if they believe pharmaceutical companies invent new diseases to make money. The resulting data are given in the table. Number who believe Political Sample pharmaceutical companies affiliation size invent diseases Democrats 788 137 Republicans 866 105 1. Is there any evidence to suggest that the proportion of voters who believe pharmaceutical companies invent diseases to make money is different for Democrats and Republicans? Use alpha = 0.01. 2. Calculate the test statistic and p value for this hypothesis test. Assume p, is the proportion of Democrats and P2 is the proportion of Republicans.
Answers
the p-value (0.208) is greater than the significance level (0.01), we fail to reject the null hypothesis
To determine if there is evidence to suggest that the proportion of voters who believe pharmaceutical companies invent diseases to make money is different for Democrats and Republicans, we can perform a hypothesis test. Let p1 be the proportion of Democrats who believe in the conspiracy theory, and p2 be the proportion of Republicans who believe in the conspiracy theory.
Let's set up the hypotheses:
Null hypothesis (H0): p1 - p2 = 0 (There is no difference in the proportions of Democrats and Republicans who believe in the conspiracy theory)
Alternative hypothesis (Ha): p1 - p2 ≠ 0 (There is a difference in the proportions of Democrats and Republicans who believe in the conspiracy theory)
We will use a two-sample proportion test to test these hypotheses. The test statistic for this test is given by:
\(\[ Z = \frac{\hat{p}_1 - \hat{p}_2}{\sqrt{\hat{p}(1-\hat{p})(\frac{1}{n_1}+\frac{1}{n_2})}} \]\)
where:
- \(\( \hat{p}_1 \)\) and \(\( \hat{p}_2 \)\) are the sample proportions of Democrats and Republicans who believe in the conspiracy theory, respectively.
- n₁ and n₂ are the sample sizes of Democrats and Republicans, respectively.
- \(\( \hat{p} \)\) is the overall proportion of belief in the conspiracy theory, calculated as the total number of believers divided by the total sample size.
The p-value is the probability of observing a test statistic as extreme or more extreme than the one calculated from the sample data, assuming the null hypothesis is true.
Given the sample data:
Democrats: n₁ = 788 and \(\( \hat{p}_1 = \frac{137}{788} \)\)
Republicans: n₂ = 866 and \(\( \hat{p}_2 = \frac{105}{866} \)\)
Let's calculate the test statistic and the p-value:
Step 1: Calculate \(\( \hat{p} \)\):
Total number of believers = 137 + 105 = 242
Total sample size = 788 + 866 = 1654
\(\( \hat{p} = \frac{242}{1654} \)\)
Step 2: Calculate the test statistic (Z):
\(\[ Z = \frac{\frac{137}{788} - \frac{105}{866}}{\sqrt{\frac{242}{1654} \cdot \left(1 - \frac{242}{1654}\right) \cdot \left(\frac{1}{788} + \frac{1}{866}\right)}} \]\)
≈ -1.258
Step 3: Calculate the p-value using the standard normal distribution table for a two-tailed test.
To calculate the p-value, we need to find the probability that a standard normal distribution is less than or greater than the absolute value of the test statistic. Since the alternative hypothesis is two-sided (p1 ≠ p2), we will calculate the p-value as twice the probability of the test statistic being greater than the absolute value of the calculated z-value.
Using a standard normal distribution table or a statistical software, we find that the p-value is approximately 0.208.
Conclusion:
Since the p-value (0.208) is greater than the significance level (0.01), we fail to reject the null hypothesis. There is insufficient evidence to suggest that the proportion of voters who believe pharmaceutical companies invent diseases to make money is different for Democrats and Republicans.
