paulina and montrose are developing a personality survey and they want to obtain an estimate of its reliability. paulina administers the survey to a group of employees one day and then she administers the exact same survey to the same employees the following week. montrose took a different approach and developed two different, yet equivalent forms of the survey and administered both forms to a sample of employees. paulina is most likely assessing reliability, while montrose is most likely assessing reliability
Paulina is most likely assessing "Test-retest reliability", while Montrose is most likely assessing "Parallel forms reliability."
What is termed as reliability?The consistency with which a method attempts to measure something is indicated by its reliability. The same method applied to the same sample in the same conditions should yield the same results. If not, the measurement method may be unreliable.
Some key points related to the reliability are-
Test-retest reliability assesses the consistency of the findings when the same test is performed on the same sample at different points in time. When measuring something which you expect to remain constant in your sample, you use it.The correlation among two equivalent versions of the a test is measured by parallel forms reliability. When you have two distinct evaluation tools or sets of questionnaire prepared to measure the same thing, you use it. It is often necessary to develop different versions of tests in educational assessment.To know more about the Test-retest reliability, here

Find parametric equations for the line passing through the points p(2, 4, 2) and q(5, 5, 3).
The parametric equations for the line passing through the points p(2, 4, 2) and q(5, 5, 3) are x=2+5t, y=4+5t and z=2+3t.
What is parametric equation?
The same values may be expressed by a variety of alternative parameterizations because parametric representations are typically non-unique (see the "Examples in two dimensions" section below).
In addition to curves and surfaces, higher dimensional algebraic varieties can also be described by parametric equations; in this case, the number of parameters is equal to the dimension of the manifold or variety, and the number of equations is equal to the dimension of the space in which the manifold or variety is taken into account (for curves the dimension is one and one parameter is used, for surfaces dimension two and two parameters, etc.).
In kinematics, where the motion of an object is represented by equations using time as the parameter, parametric equations are frequently utilized.
Calculations:
Parametric equation of line PQ is
x=2+5t,y=4+5t and z=2+3t
parametric equation of line AB is
x=x1+tx2, y=y1+ty2 and z=z1+tz2
Here as we have P(2,4,2) and Q(5,5,3)as two points,
parametric equation of line
PQ is x=2+5t, y=4+5t and z=2+3t
i.e.

If BC = x + 1, CD = 14x − 10, and BD = 6, what is CD? x + 1 B 14x − 10 C D 6 Simplify your answer and write it as a proper fraction, mixed number, or integer.\
Solving all the linear equation The value of CD is 6.
An algebraic equation known as a linear equation has terms that are either constants or variables raised to the first power. Alternatively put, none of the exponents can be greater than 1. As an illustration, while x is a variable raised to the first power, x2 is a variable raised to the second power. An illustration of a constant is 5.
Now According to the question
BC = x+1
CD = 14x - 10
BD = 6
by this we can say that
BC + CD = BD
no by substitution method putting values of BC , CD and BD
(x + 1) + (14x - 10) = 6
15x - 9 =6
15x = 15
x = 1
now again by substitution method putting value of x in to 14x-10 we get
CD = 14(1)-10
CD = 4

A propositional formula may alternatively be referred to as a phrase, a propositional expression, or a sentential formula.
Simple statements like "five is greater than three" or propositional variables like p and q are combined to build a propositional formula using connectives or logical operators like NOT, AND, OR, or IMPLIES.

The graph of the absolute value parent function, f(x) = Ixl, is stretched

O A. g(x) = |x|
B. g(x) = 16x1
C. g(x) = x + 6|
O D. g(x) = 61x1
Transformations are used to move a function from one position to another. The function of g(x) is g(x) = | x/6|.
Given that:
f(x) = |x|
The rule of a horizontal stretch by factor k is:
(x, y) → (x/k,y)
This means that:
g(x) = f(x/k)
In this case, k = 6
So, we have:
g(x) = f(x/6)
Calculate f(x/6)
f(x/5) = |x/6|
Hence, the function of g(x) is
g(x) = |x/6|.

The minimum IQ score for the top 10% of the population is 0.0179.
Standard deviation:
Standard deviation means the root of the variance in the given grouped or ungrouped data.
The standardized value is the value decreased by the mean, divided by the standard deviation:
z = (x- μ) / σ
where
x: the observation (a specific value that you are calculating the z-score for).
Mu(μ): the mean.
Sigma(σ): the standard deviation.
Given,
The human IQ scores are approximately normally distributed with a mean of 100 and a standard deviation of 15.
Here we need to find the minimum IQ score for the top 10% of the population.
We know that,
x = 131.5
μ = 200
σ = 15
So, when we apply the values on the formula,
Then we get,
=> z = 131.5 - 100 /15
=> z = 2 .10
Determine the corresponding probability using table A-2:
=> P(Z>2.10) = 1 − P(Z<2.10)
=> 1 − 0.9821
=> 0.0179
Therefore, the minimum IQ score for the top 10% of the population is 0.0179.
