Ensuring that data is collected the same way each time it is collected is an example of:_______.
Ensuring that data is collected the same way each time it is collected is an example of data consistency.
What is data consistency?In database systems, consistency refers to the requirement that any given database transaction only changes affected data in permitted ways. Data written to a database must be valid according to all defined rules, including constraints, cascades, triggers, or any combination, for the database to be consistent. This operation can be modified per transaction. So, for example, a programmer can specify that only two nodes must read newly input data before recognizing data consistency. Once it crosses that barometer, it is considered consistent data. Data consistency is demonstrated by ensuring that data is collected in the same manner each time it is collected.Therefore, ensuring that data is collected the same way each time it is collected is an example of data consistency.

Reflected over the x-axis , Compressed by a factor of 0.4. , Translated 2 units left.
What is Reflected over the x-axis?
Point (x, y) is reflected across the x-axis as (x, -y). The y-coordinate stays the same when a point is reflected across the y-axis, but the x-coordinate is assumed to be the additive inverse.
[tex]y = \sqrt[3]{x}[/tex]
[tex]y' = - 0.4\sqrt[3]{x - 2}[/tex]
Required
The transformation from y to y'
First, y is reflected over the x-axis.
The transformation rule is
(x, y) → ( x, -y)
So, we have
y = ∛x becomes
y' = - ∛x
Next, it was compressed by a scale factor of 0.4
The rule is
y' = k * y
Where k is the scale factor (i.e. k = 0.4)
So, we have
y' = 0.4 * -∛x
y' = - (0.4)∛x
Lastly, the function is translated 2 units left;
The rule is
(x, y) → ( x - 2 ,y)
So, we have

The branch of statistics that uses sample statistics to estimate a population parameter or test a hypothesis about such a parameter is best referred to as?
The branch of statistics that uses sample statistics to estimate a population parameter or test a hypothesis about such a parameter is best referred to as inferential statistics.
What is inferential statistics?Statistical inference is the method of using data analysis to infer characteristics of a probability distribution. Inferential statistical analysis deduces population properties, for example, by testing hypotheses and generating estimates. The observed data set is assumed to be a sample from a larger population. Inferential statistics is the branch of statistics that uses sample statistics to estimate a population parameter or test a hypothesis about such a parameter.Descriptive statistics is only concerned with the properties of the observed data and does not assume that the data come from a larger population. Inferential statistics differ from descriptive statistics.Therefore, the branch of statistics that uses sample statistics to estimate a population parameter or test a hypothesis about such a parameter is best referred to as inferential statistics.

Answer:
the volume increases by a factor of 27
Step-by-step explanation:
pretend that the volume V can be
V=l×w×h 'l' is length, 'w' is width, and 'h' is height. Let's increase all of those measures by a factor of 3.
The new volume will be V': V'=3l × 3w × 3h
we can rearrange:V'=3×3×3×l×w×h
we now have l×w×h by itself: V'=3^3 ×l×w×h=3^3×V
You can now see that if all the linear dimensions of the prism are tripled, we get an increase of 3^3 to the original volume:

Answer: 1/5
Step-by-step explanation: 3/15 divided by 3= 1/5
The answer is 1/5.
First, You have to figure out if there are any numbers that go into both the numerator and denominator evenly.
This number, in this problem, would be three.
This is because 3/3=1 and 15/3=5.
Given that it asks for a fraction in the simplest form, we of course have order those numbers as numerator and denominator.
The three is the numerator, or, above the fifteen, or the denominator.
This must mean that the one is the numerator.
Because the 1 is the numerator, that must mean the 5 is the denominator, which brings us to the answer.... 1/5

What are the advantages of the edf scheduling algorithm over the rate-monotonic scheduling algorithm?
When compared to other scheduling methods for real-time systems, EDF is quite effective. It can maintain all work deadlines while increasing CPU utilization to around 100%.
What are the EDF scheduling algorithm and monotonic scheduling algorithm?The earliest deadline first (EDF) algorithm is a dynamic priority scheduling algorithm that is used in real-time systems.
EDF is an optimal algorithm, it will schedule a task set if possible. EDF is also independent of the task's period and can be used to schedule aperiodic tasks because it makes no assumptions about job periodicity. If two jobs have the same absolute deadline, choose one at random.
When compared to fixed priority scheduling techniques such as rate-monotonic scheduling, EDF can guarantee all system deadlines at higher loading. On non-preemptive uniprocessors, EDF is also an optimal scheduling algorithm, but only among scheduling algorithms that do not allow inserted idle time.

The value of AB in the geometry is 24 units.
How to find the length AB using geometry?According to the diagram,
BD ≅ BC
BD = 5x - 26
BC = 2x + 1
AC = 43
Therefore, the value of AB can be found using the knowledge of geometry.
BD = BC
5x - 26 = 2x + 1
5x - 2x = 1 + 26
3x = 27
divide both sides by 3
x = 27 / 3
x = 9
Therefore,
BC = 2x + 1 = 2(9) + 1 = 18 + 1 = 19
AC = BC + AB
AB = AC - BC

The perimeter of the rectangle with length 8x - 1 and width 10x + 3 is 20x + 6
What is perimeter of the rectangle?
The formula P=2l+2w, where l is the rectangle's length and w is its width, determines the perimeter P of a rectangle. The equation A=lw, where l is the length and w is the width, determines the area A of a rectangle.The perimeter of the rectangle with length 8x - 1 and width 10x + 3 is 20x+ 6
The formula for calculating the perimeter of a rectangle is expressed as:
P = 2( l + w)
Given the following parameters
length l = 8x - 1
width w = 2x + 4
Substitute the expressions for the length and width into the formula;
P = 2(8x - 1 + 2x + 4)
P = 2(10x + 3)
Distribute 2 over each term in the parenthesis
P = 2(10x) + 2(3)
P = 20x + 6

A biologist recorded plant heights in centimeters:
23, 21, 3, 31, 27, 28, 32, 24, 30
The outlier is removed from the data set. By how many centimeters does
the range decrease? Help
Answer:
18 cm
Step-by-step explanation:
Range = Largest Number - Smallest Number
We know the following from the original data set:
Largest Number = 32 cm
Smallest Number = 3 cm
Original Range = 32 cm - 3 cm = 29 cm
The outlier is 3 cm because all the other numbers are relatively close to ine another in their 20s and 30s. If we remove 3 cm from the data set, we know the following:
Largest Number = 32 cm (Doesn't change)
Smallest Number = 21 cm
New Range = 32 cm - 21 cm = 11 cm
We can compare the two ranges by subtracting the larger range from the smaller range:
Range Difference = 29 cm - 11 cm = 18 cm
Therefore, the range decreases by 18 cm when we remove the outlier.
