If the other student chose to test the variable selected in the previous question, which of the following independent variables should not be kept constant throughout the experiment?
A. the amount of soil that is provided to each plant
B. the amount of water that is provided to each plant
C. the amount of sunlight that is provided to each plant
D. the type of plant used in each pot
Answers
The independent variables should not be kept constant throughout the experiment is D. the type of plant used in each pot.
In a controlled experiment, you want to isolate and test the effect of one independent variable while keeping all other variables constant. This helps ensure that any observed effects are likely due to the manipulated variable and not influenced by other factors.
The variable that the other student is testing is the dependent variable (the one being measured). Since you are trying to isolate the effects of this variable, you should keep all other variables constant to clearly attribute any changes to the manipulated factor.
In an experiment testing the effect of water on plant growth, the amount of water should not be kept constant, making it the independent variable that is manipulated, while other factors like soil and sunlight should remain constant as control variables.
Explanation:The student's question pertains to an experimental setup to test the impact of a variable on plant growth. In this context, if the amount of water is the independent variable, then it should not be kept constant throughout the experiment because changes in the water amount are what we are testing for their effect on plant growth. Consequently, the correct answer would be B, the amount of water provided to each plant, because this aspect of the experiment should vary, while the other factors listed should remain constant to ensure a fair test of the variable in question.
When setting up an experiment, it is crucial to hold certain elements constant (the control variables), such as the type of plant, the amount of soil, and the amount of sunlight, ensuring that any observed changes in the experiment's outcome can be attributed to the manipulation of the independent variable. The dependent variable, which is the outcome being measured in this case, plant growth, is expected to change in response to the independent variable, which is the amount of water provided to each plant.

A random sample of 50 people from a town with a population of 14,878 were asked to name their favorite flavor of ice cream. If 7 people in the sample named chocolate as their favorite ice‑cream flavor, about how many people in the town would be expected to name chocolate?
Answers
And you would round it to the nearest one since you wouldn’t split a human so
2083 (I got .14 from multiplying 7/50 •2)
There are "2082.92" persons in town who are anticipated to name chocolate, and the rest of the conversation can be summarised as follows:
Flavor Calculation:Number of people = 50
Total population= 14,878
selected people = 7
As per the given condition using the formula to calculate the value that is:
[tex]\to 7\times 14878 \div 50 \\\\\to 7\times \frac{14878}{ 50} \\\\[/tex]
Reducing the fraction:
[tex]\to \frac{7 \times7439}{25}[/tex]
Calculating the product or quotient value that is:
[tex]\to \frac{52073}{25}[/tex]
[tex]\to 2082 \frac{23}{25}\\\\[/tex]
OR
[tex]\to[/tex] 2082.92

a good faith estimate is required by law to be given by the lender to the borrower within three days of submitting a loan application. what are some drawbacks of not having that estimate at time of closing ?
Answers
The correct answer to this open question is the following.
A good faith estimate is required by law to be given by the lender to the borrower within three days of submitting a loan application. Some drawbacks of not having that estimate at the time of closing are the following. The Closing Disclosure has designated some fee levels of tolerance, so fees can not change to protect the loan estimated. The only exception is when something unexpected happens. The three levels of tolerance are: the zero-tolerance is the fees for the broker. These are fixed. The 10% tolerance accepts a modification of the 10% of fees in case another expenditure is needed. Finally, the no-tolerance concept permits many changes in fees for services beyond the broker assistance.
The drawbacks of not having that estimate at the time of closing will be that the individual may have to pay a higher fee.
The Good Faith Estimate was put in place in order to encourage consumers to be able to shop and also compare the fees from different lenders before a mortgage provider will be chosen.
The good faith estimate is required by law to be given by the lender to the borrower within three days of submitting a loan application.
It's vital to help the customers understand the services that they needed to shop for and thereby get a lower interest. In this case, if one doesn't have the estimate, a higher fee will be paid.

Three starts die and become deead stars. one of the theree becomes a neutron star, another becomes a black hole, and the third becomes white dwarf. which star, before it died, would have been the most massive and which star would have been the least massive?
Answers
Answer:
Black hole most massive and white dwarf least massive should be correct. It really just depends on the original size of the star and it's gravitational pull pre death.
Explanation:
Just what I learned over time. I would still do more research on the subject though.
The dead star which is most massive before it died is a black hole and the star which is least massive is White dwarf.
What is the dead stars?When the fusion in a star is stopped, it is considered as the dead starts. The collapse and reaction after the fusion stops create three types of stars-
Neutron Star-Neutron Star are those dead stars which has low dense. They are the least massive compare to black hole.Black hole-The mass of this black hole is maximum in all the three. When the star is so massive as, it cannot be collapsed and be halted to become a black hole. White dwarf-When the mass of a star is much less as it does not become a black hole or Neutron Star, then it becomes a white dwarf.Thus, the dead star which is most massive before it died is a black hole and the star which is least massive is White dwarf.

c. The underlying equation/math models the probability of a specific outcome occurring
d. The strength of results can be expressed using odds ratios
Answers
The statement which is not true of logistic regression is: a. Outcomes need to be categorical nominal.
A logistic regression can be defined as a predictive analysis that can be used to model the probability of a categorical event or class existing.
Basically, a logistic regression is a classification model that can be used to predict a dependent data variable (binary outcome) by analyzing the relationship existing between one or more independent data variables.
Some of the characteristics of logistic regression include the following:
There must be interaction terms in a logistic regression model.The strength of results in a logistic regression model can be expressed using odds ratios (OR).The underlying equation (math) can be used to model the probability of a specific outcome occurring.A logistic regression model must contain a categorical data such as: pass or fail, good or bad, tall or short, alive or dead, yes or no, win or lose, etc.In conclusion, the outcome of a logistic regression model need not to be categorical but a nominal data (binary outcome).
