The company wants to use the package that has the least amount of wasted space. The company should choose the prism because it has approximately 11. 6 in. 3 less wasted space than the cylinder. The prism because it has approximately 14. 1 in. 3 less wasted space than the cylinder. The cylinder because it has approximately 11. 6 in. 3 less wasted space than the prism. The cylinder because it has approximately 14. 1 in. 3 less wasted space than the prism
Volume is a three-dimensional scalar quantity. The company should choose the cylinder because it has approximately 11.6in³ less wasted space than the prism.
What is volume?A volume is a scalar number that expresses the amount of three-dimensional space enclosed by a closed surface.
The volume of the two balls with a radius of 1.5 inches is,
[tex]=2 \times \dfrac43 \times \pi r^3 \\\\= 28.2743\rm\ in^3[/tex]
The Volume of the prism with dimensions 6in × 3in × 3in are,
Volume of the prism = 6in × 3in × 3in = 54 in³
The volume of the cylindrical box with a radius of 1.5 in and a height of 6 inches is,
Volume of Cylinder = πr²h = π × (1.5)² × 6 = 42.4115 in³
Wasted volume in Prism, when two balls are inside,
Wasted Volume = 54in³ - 28.27in³ = 25.72566 in³
Wasted Volume in Cylinder, when two balls are inside,
Wasted Volume = 42.4115in³ - 28.27in³ = 14.137 in³
The difference in the waste volume of prism and cylinder,
Difference = 25.72566in³ - 14.137in³ = 11.6in³
Hence, The company should choose the cylinder because it has approximately 11.6in³ less wasted space than the prism.

Researchers are studying two different designs of computer keyboards, j and k, to investigate the effectiveness of the design on the speed of data entry. The researchers believe there is a tendency for people entering data with keyboard j to have faster entry times compared with people entering data with keyboard k. Using the same set of data for entry, the researchers randomly assigned 5 people to keyboard j and 6 people to keyboard k and recorded the number of seconds each person took to enter the data. The following dotplots show the observed entry times for the two keyboards
The data from the people using the j and the k keyboards reveal that it is not appropriate to conduct the two-sample statistical t-test, as there was the presence of outliers.
What is a two-sample t-test?It is a statistical test that is used in the determination of the equality of the two mean populations. The test is used for the analysis of the statistical difference between the two tests.
The test data for the two keyboards have been based on the presence of the outliners in the data. This helps in the analysis of the population with the median, and not with the mean.

How much energy is required to vaporize 41. 4 g of dichloromethane (ch 2cl 2) at its boiling point, if its δh vap is 31. 6 kj/mol?
Answer: 15.4 kJ
Explanation:
Molar mass of CH2Cl2,
MM = 1*MM(C) + 2*MM(H) + 2*MM(Cl)
= 1*12.01 + 2*1.008 + 2*35.45
= 84.926 g/mol
Mass(CH2Cl2) = 41.4 g
Use:
number of mol of CH2Cl2,
n = mass of CH2Cl2/molar mass of CH2Cl2
= (41.4 g)/(84.93 g/mol)
= 0.4875 mol
Given:
ΔH = 31.6 KJ/mol
= 31600 J/mol
Use:
Q = ΔH * number of mol
= 31.6 KJ/mol * 0.4875 mol
= 15.4 KJ
Therefore, it takes 15.4 kJ of energy to vaporize 41. 4 g of CH₂Cl₂ at its boiling point
A survey of 225 students showed the mean number of hours spent studying per week was 20.6 and the standard deviation was 2.7. assuming a 90% confidence level, the margin of error is approximately
Answer:
Assuming a 90% confidence level, the margin of error is approximately
0.3
Which of the following gives the confidence interval?
between 20.3 and 20.9
Explanation:
A survey of 225 students showed the mean number of hours spent studying per week was 20.6 and the standard deviation was 2.7, the margin of error is approximately 0.2948.
What is standard deviation?Standard deviation is a statistical measure that describes the amount of variation or dispersion of a set of data values.
It measures the average amount of deviation of each data point from the mean (or average) of the entire dataset.
To find the margin of error for a sample mean, we use the formula:
Margin of error = z * (standard deviation / sqrt(sample size))
where z is the z-score corresponding to the desired confidence level. For a 90% confidence level, the z-score is 1.645 (we can look this up on a standard normal distribution table).
Plugging in the values given in the problem:
Margin of error = 1.645 * (2.7 / sqrt(225))
= 1.645 * (2.7 / 15)
= 0.2948 (rounded to four decimal places)
Therefore, the margin of error is approximately 0.2948.

What is the variance of the data? 0.0625 0.25 0.5 1.5
The variance of the dataset is the square of their standard deviation
The variance of the dataset is 0.307
How to determine the variance?The dataset is given as;
0.0625 0.25 0.5 1.5
Calculate the mean using:
μ = Sum/Count
So, we have:
μ = (0.0625 + 0.25 + 0.5 + 1.5)/4
Evaluate
μ = 0.578125
The variance is then calculated using:
[tex]\sigma^2 = \frac{\sum(x - \mu)^2}{n}[/tex]
So, we have:
[tex]\sigma^2[/tex] = [(0.0625 - 0.578125)^2 + (0.25 - 0.5781250^2 + (0.5 - 0.578125)^2 + (1.5 - 0.578125)^2]/4
Evaluate
[tex]\sigma^2[/tex] = 1.2294921875/4
Divide
[tex]\sigma^2[/tex] = 0.30737304687

Decide if the following sentence is grammatically correct or incorrect. está bien por ahora. correct incorrect
Answer:
That is correct
está bien por ahora is grammatically correct.
What is Grammar?
A natural language's grammar is a system of structural rules that limit how sentences, phrases, and words can be put together by speakers or writers.
The phrase can also be used to describe the study of such restrictions, a subject area that covers phonology, morphology, and syntax as well as the frequently added fields of phonetics, semantics, and pragmatics. Traditional grammar and theoretical grammar are the two methods now used to study grammar.
These limitations, the bulk of which - at least in the case of one's native language(s) - are acquired not by conscious study or instruction but rather by hearing other speakers, have successfully been internalized by fluent speakers of a linguistic variation or lect.

Manny is using a computer model to investigate the effects of substitution mutations. The model presents manny with a long base sequence for a gene. Manny then selects one base for a mutation, such as by substituting cytosine, "c", for adenine, "a". Manny completes many trials of mutations. In most trials, the result of the substitution mutation is either no effect, or a polypeptide in which one amino acid is altered. In one trial, however, the result is a truncated polypeptide. Many of its terminal amino acids are missing. What is the most likely explanation for the truncated polypeptide
The truncated polypeptide results in the computer simulations performed by Manny can be found with the alteration in the gene structure and the formation of the stop codon in between the chain sequence.
What is truncated polypeptide?The truncated polypeptide is the sequence of the amino acid that is modified in a way to enable the formation of the tertiary and the quaternary structure of the protein.
The truncation in the polypeptide chain can be attained with the alteration in the gene structure. The attempts of Manny to perform the substitution mutation may result in the change in the cytosine nucleotide at the C or the N terminal of the polypeptide chain.
This results in the formation of the termination in the elongation with the stop codon, and thereby forms the truncated polypeptide.
