What is cube and square?
Any number multiplied by itself is a square number. 0 through 1, 4, 9, 16, 25, 36, 49, 64, 81, and 100 are the square numbers. A number multiplied by itself three times is a cube number. Up to 100, the cube numbers are 1, 8, 27, and 64. Cubes in three dimensions can be used to represent cube numbers.
Given that the value of a cube and a square, A, is zero when A = -1, we can write the equation:
a^3 + A^2 = 0
Substituting A = -1 into this equation gives us:
a^3 + (-1)^2 = 0
Simplifying the right-hand side of this equation:
a^3 + 1 = 0
So,
a^3 = -1
Taking the cube root of both sides:
a = -1^(1/3)
The value of k is the cube root of -1, which is a complex number and is represented as an imaginary number, i.e., "i".
Therefore, the value of k is "i".

What is 145.65 divided by 21.2?
Answer: 6.87
Step-by-step explanation:
21.2 / 145.65
Move to the decimal to the right 1 time to make 21.2 to 212 and 145.65 to 1456.5.
Then you want to look for a number you can multipl 212 into the 1456.
In this case, 212 times 6 because it equals 1272.
If you multiply 212 times 7, you get 1484 (which is over the number of 1456 { we dont want that}).
Then you continue multiplying the number until you get to 0, or in other words, a remainder. In which I got, 6.870
a1=(1,3,-1) , a2=(-5,-8,2) and b=(3,-5,h). For what values of h is b in plane spanned by a1 and a2?
The value of h for which b in plane spanned by a1 and a2 is 3.
If b is spanned by a1 and a2, then for some constant x and y
b = x*a1 + y*a2
(3, -5, h) = x(1, 3, -1) + y(-5, -8, 2)
So we get equations
x - 5y = 3
3x - 8y = -5
-x + 2y = h
Solving x - 5y = 3 and 3x - 8y = -5
(3x - 8y) - 3(x - 5y) = -5 - 3*3
7y = -14
y = -2
Also x = 3 + 5y = 3 + 5*-2
So x = -7
Now h = -x + 2y
= -(-7) + 2*(-2)
= 7 - 4
= 3

would this be an enumerative or an analytic study? explain your reasoning.
This study is enumerative since there is a small, identifiable population of things to sample from. This investigation is analytical since there is a limitless population of items from which to sample.
The administrator may select stratified random sample or basic random sampling to solve the CSU problem.
To determine the average distance between hometown and campuses using simple random sampling, all students across the 23 CSU campuses are taken into account.
This approach is flexible, and the statistical analysis would be straightforward. In the stratified random sampling, each campus is treated as a single cluster. A random sample is taken from each campus, and the distance between home and campus is calculated.
The statistical findings would be more reliable and instructive using this strategy. This study is unmistakably enumerative. Here, the administrator is looking into the typical travel time between home and university.
By moving the students from one campus to another, he can utilize this outcome as the basis for taking the necessary action to reduce the distance.

what proportion of the area is in each tail? enter your answer to 3 decimal places.
The proportion of the area in each tail is 0.025, or 2.5%. This means that 2.5% of the area of the normal distribution lies in each of the two tails.
The total area of the normal distribution is 1.
The area of the left tail is 0.3413.
The area of the right tail is 0.3413.
Therefore, the proportion of the area in each tail is 0.341.
The normal distribution is a symmetric probability distribution that has a single peak and two tails extending outwards from the peak. The proportion of the area in each tail of the normal distribution is 0.025, or 2.5%. This proportion is the same for both tails and is determined by the fact that the normal distribution is symmetric. This means that 2.5% of the area of the normal distribution lies in each of the two tails. This area can be calculated by multiplying the total area of the normal distribution by 0.025. The total area of the normal distribution is equal to 1, and so the area in each tail is equal to 0.025. This proportion is constant regardless of the mean and standard deviation of the normal distribution. The proportion of the area in each tail of the normal distribution is an important concept in statistics, as it is used to calculate probabilities of certain events occurring.

A type of insurance called health insurance pays for medical costs incurred as a result of disease. These costs might be connected to hospitalization charges, medication costs, or professional fees.
Health insurance comes in two different categories:
1. Medical Insurance Plans: The most fundamental form of health insurance is a hospitalization or Mediclaim plan. When you are checked into a hospital, they pay for your medical care. By submitting the original bills, the compensation is based on the actual costs incurred at the hospital. Up to a specific threshold, the majority of these policies offer full family coverage.
2. Critical illness insurance policies: These policies provide coverage for a number of life-threatening illnesses. These illnesses may need ongoing care or possibly a change in lifestyle. In contrast to hospitalization plans, the payout is based on the customer's selected Critical Illness coverage rather than actual hospital costs.

A nontoxic furniture polish can be made by combining vinegar and olive oil. The amount of oil should be three times the amount of vinegar. How much of each ingredient is needed in order to make 46 oz of furniture polish?
Here, the 11.5 oz of vinegar ingredient is needed in order to make 46 oz of furniture polish .
So in this problem it says a furniture polish can be made containing or combining vinegar and olive oil and the amount of oil should be three times the amount of vinegar. So I'm gonna make vinegar X. And oil three X. How much of each ingredient is needed in order to make 46 oz of furniture Polish. So I'm gonna go ahead and add these together. Okay. Yes. Which means that four x. equals 46 and divide by four So X. is 11.5. So that means that for vinegar we need 11.5 oz. And then I'm going to multiply that by three to get 34.5 oz for the oil. And if you can find those together just to check you get 46. So this would be the amount of both ingredients.
To make 46 oz of furniture polish, you will need 3 times as much olive oil as vinegar.
So, you need 46 oz / 4 = 11.5 oz of vinegar.
And 11.5 oz * 3 = 34.5 oz of olive oil.

group is given an achievement test to compare its proficiency with that of the other group.
The study is an Experiment because the researchers control one variable to determine the effect on the response variable.
What is an experiment ?
A process used to confirm or deny a theory, as well as assess the effectiveness or possibility of something that has never been performed before, is called an experiment. By showing what happens when a particular element is modified, experiments shed light on cause-and-effect relationships.
Since the study randomly divided the fifth-grade students into two groups, one of which received a solution or treatment in the form of instruction using a reform or modern method while the other group did not receive any treatment because it was instructed using traditional methods, the study's rationale for doing so is that. Therefore, this shows an Experiment study.
In an experiment study, there are two different sorts of groups: the experiment group and the control group. The control group often does not receive any care or assistance from the researchers or scientists. In order to assess the response variable, which in this case is the subject or explained variable (teaching using the Reform method), researchers typically change the subject or explained variable. This allows them to draw conclusions that are based on cause and effect relationships.

The statement "the law of sines can be used to solve triangles where three sides are known" is false.
A triangle is a three-sided polygon, with each side representing a line segment connecting two vertices. To fully determine a triangle, we need to know at least three pieces of information about it, such as the lengths of its sides, or the measures of its angles.
The law of sines is a mathematical formula that relates the ratios of the lengths of the sides of a triangle to the angles opposite those sides. It states that the ratio of the length of a side of a triangle to the sine of the angle opposite that side is constant for all three sides of the triangle.
However, the law of sines cannot be used to solve a triangle if all three sides are known. To solve a triangle, we need to have additional information, such as the angles or some side-angle pairs. The law of sines can only be used to find missing side lengths or angle measures if we have at least one side length and one angle measure, or two side lengths and an angle not contained between them.

if the fastest car on earth can travel 380 miles in 0.5 hours, how many minutes would it take to travel 257 miles? if the fastest car on earth can travel 380 miles in 0.5 hours, how many minutes would it take to travel 257 miles?
It would take the fastest car on earth approximately 20.27 minutes to travel 257 miles.
We can calculate the time it takes for the fastest car on earth to travel 257 miles by determining its speed and then dividing the distance to be traveled by the speed.
First, let's determine the speed of the car. The car can travel 380 miles in 0.5 hours, so its speed is:
Speed = Distance / Time = 380 miles / 0.5 hours = 760 miles per hour
Next, we need to convert the speed from miles per hour to miles per minute, so we can use it to calculate the time it takes to travel 257 miles. To do this, we divide the speed by 60:
Speed in miles per minute = 760 miles per hour / 60 minutes per hour = 12.67 miles per minute
Finally, we can calculate the time it takes to travel 257 miles by dividing the distance to be traveled by the speed:
Time = Distance / Speed = 257 miles / 12.67 miles per minute = 20.27 minutes
So it would take the fastest car on earth approximately 20.27 minutes to travel 257 miles.

It would take the fastest car on earth approximately 20.27 minutes to travel 257 miles.
We can calculate the time it takes for the fastest car on earth to travel 257 miles by determining its speed and then dividing the distance to be traveled by the speed.
First, let's determine the speed of the car. The car can travel 380 miles in 0.5 hours, so its speed is:
Speed = Distance / Time = 380 miles / 0.5 hours = 760 miles per hour
Next, we need to convert the speed from miles per hour to miles per minute, so we can use it to calculate the time it takes to travel 257 miles. To do this, we divide the speed by 60:
Speed in miles per minute = 760 miles per hour / 60 minutes per hour = 12.67 miles per minute
Finally, we can calculate the time it takes to travel 257 miles by dividing the distance to be traveled by the speed:
Time = Distance / Speed = 257 miles / 12.67 miles per minute = 20.27 minutes
So it would take the fastest car on earth approximately 20.27 minutes to travel 257 miles.
Therefore, It would take the fastest car on earth approximately 20.27 minutes to travel 257 miles.

True or False: An observational study itself can never establish cause and effect.
We are unable to establish causation or cause-and-effect correlations using observational data. Observational studies are fantastic for describing a particular group, contrasting groups, or looking at the patterns or relationships between variables.
What is an observational study?Observational research Without making any attempts to change the value of the explanatory or response variables, this measurement only considers the response variable's value. To put it another way, in an observational study, the researcher just watches how the participants behave without attempting to sway the results.Observational studies involve observing the results of a risk factor, diagnostic test, treatment, or other intervention without attempting to alter who is or is not exposed to it.Observational studies are less reliable than experimental research, are more subject to bias and confounding, and cannot be used to prove causation.To Learn more About Observational studies Refer To:

88 63at a certain stage of a criminal investigation, the inspector in charge is 60% convinced of the guilt of a certain suspect. suppose, however, that a new piece of evidence which shows that the criminal has a certain characteristic (such as left-handedness, baldness, or brown hair) is uncovered. if 20% of the population possesses this characteristic, how certain of the guilt of the suspect should the inspector now be if it turns out that the suspect has the characteristic? you may suppose that the probability of the suspect having the characteristic if they are, in fact, innocent is equal to 0.2, the proportion of the population possessing the characteristic.
The probability that the inspector in-charge is convinced that the suspect is guilty given he/she has brown hair is 0.882.
P(C) = P(C∣G)P(G) + P(C∣Gc)P(Gc) = (1)(0.6)+(0.2)(0.4) = 0.68
Simply put, probability is the likelihood that something will occur. When we don't know how an event will turn out, we can discuss the likelihood or likelihood of several outcomes. Statistics is the study of events that follow a probability distribution.
This is then used to update the inspector's belief in the suspect's guilt posterior to discovering that the suspect does have that characteristic.
P(G∣C) = (P(G)P(C∣G))/P(C)
=1(0.6)/0.68
=0.882
So the probability that the inspector in-charge is convinced that the suspect is guilty given he/she has brown hair is 0.882.

Which linear inequality is represented by the graph?
ys-x-1
y²x-1
y < 3x - 1
y> 3x - 1
The linear inequality represented by the graph is given as follows:
y ≤ x/2 + 3.
How to obtain the linear inequality?First we consider the slope-intercept definition of a linear function, given as follows:
y = mx + b.
In which:
m is the slope, defining by how much y increases when x increases by one.b is the intercept, representing the value of y when x = 0.From the graph, we have that it crosses the y-intercept at y = 3, hence the intercept b is given as follows:
b = 3.
When x increases by two, y increases by one, hence the slope m is given as follows:
m = 1/2
m = 0.5.
Hence:
y = x/2 + 3.
The inequality is composed by values below the line, with a solid line, hence it is given as follows:
y ≤ x/2 + 3.

Step-by-step explanation:
The slope of the line can be found by finding the rise over the run between two points on the line. Using the points (1,0) and (2,5), the slope can be found as follows:
m = (5-0)/(2-1) = 5
Now that we have the slope, we can use the point-slope form of a line to find the equation of the line in slope-intercept form. Using the point (1,0) and the slope (5), we have:
y - 0 = 5(x - 1)
Simplifying and solving for y, we have:
y = 5x - 5
So the equation of the linear function represented by the table is:
y = 5x - 5.
