why might a researcher choose purposive sampling over systematic sampling? group of answer choices purposive sampling is always cheaper. external validity is not vital to the researcher’s study. only purposive sampling allows the researcher to study a particular type of participant. the researcher does not have to specify a population of interest ahead of time

Answers

The correct answer is Option C. A researcher might choose purposive sampling over systematic sampling for several reasons. One key reason is that purposive sampling allows the researcher to study a particular type of participant.

This means that the researcher can select individuals who possess specific characteristics or traits that are relevant to their study.

By handpicking participants, the researcher can ensure that the sample represents the specific population they are interested in studying, which is particularly useful when investigating rare or hard-to-reach populations.

On the other hand, systematic sampling involves selecting participants at regular intervals from a larger population.

This method may not provide the same level of control in selecting participants based on specific characteristics.

While systematic sampling can be more efficient in terms of time and cost, it may not be suitable for certain research objectives that require a targeted approach.

It is important to note that neither method is inherently cheaper or more expensive than the other, and the choice between them depends on the research objectives and the specific population under investigation.

Therefore, option A is incorrect.

Option B is also incorrect because external validity is still important in research regardless of the sampling method chosen.

Option D is also incorrect since researchers using purposive sampling must still specify their population of interest.

Thus, the correct answer is option C.

Consider the given pseudo code. Write the function T(n) in terms of the number of operations, and then give the asymptotic (big Oh) complexity of the algorithm, show all the work you do. [ write the summation formula and solve it, or use the "Look for pattern"method. a. Matrix Multiplication

Answers

The function T(n) in terms of the number of operations is:

T(n) = 2n^3 + 3n^2 + 2n + 1 and the asymptotic complexity of the matrix multiplication algorithm is O(n^3).

To analyze the provided pseudo code for matrix multiplication and determine the function T(n) in terms of the number of operations, we need to examine the code and count the number of operations performed.

The pseudo code for matrix multiplication may look something like this:

```

MatrixMultiplication(A, B):

   n = size of matrix A

   C = empty matrix of size n x n

   for i = 1 to n do:

       for j = 1 to n do:

           sum = 0

           for k = 1 to n do:

               sum = sum + A[i][k] * B[k][j]

           C[i][j] = sum

   return C

```

Let's break down the number of operations step by step:

1. Assigning the size of matrix A to variable n: 1 operation

2. Initializing an empty matrix C of size n x n: n^2 operations (for creating n x n elements)

3. Outer loop: for i = 1 to n

- Incrementing i: n operations  

- Inner loop: for j = 1 to n

- Incrementing j: n^2 operations (since it is nested inside the outer loop)

- Initializing sum to 0: n^2 operations

- Innermost loop: for k = 1 to n

- Incrementing k: n^3 operations (since it is nested inside both the outer and inner loops)

- Performing the multiplication and addition: n^3 operations

- Assigning the result to C[i][j]: n^2 operations

- Assigning the value of sum to C[i][j]: n^2 operations

Total operations:

1 + n^2 + n + n^2 + n^3 + n^3 + n^2 + n^2 = 2n^3 + 3n^2 + 2n + 1

Therefore, the function T(n) in terms of the number of operations is:

T(n) = 2n^3 + 3n^2 + 2n + 1

To determine the asymptotic (big O) complexity of the algorithm, we focus on the dominant term as n approaches infinity.

In this case, the dominant term is 2n^3. Hence, the asymptotic complexity of the matrix multiplication algorithm is O(n^3).

A contractor borrows $1,000 at 11.8% interest rate per annum to buy material for a job. The debt is paid 18 months later. What amount is paid in interest?

Answers

The amount paid in interest for this loan is approximately $180.00.

To calculate the amount paid in interest, we need to consider two important factors: the principal amount borrowed and the interest rate. In this case, the principal amount borrowed is $1,000, and the interest rate is 11.8% per annum.

First, let's calculate the interest for the entire loan duration of 18 months. To do this, we need to convert the interest rate from an annual rate to a monthly rate, as the loan duration is given in months.

To calculate the monthly interest rate, we divide the annual interest rate by 12 (the number of months in a year):

Monthly Interest Rate = Annual Interest Rate / 12

= 11.8% / 12

= 0.118 / 12

= 0.009833 (approximately)

Next, we calculate the total interest paid by multiplying the monthly interest rate by the principal amount borrowed and the loan duration in months:

Total Interest = Monthly Interest Rate * Principal Amount * Loan Duration

= 0.009833 * $1,000 * 18

= $180.00 (approximately)

Which statements hold true for the function?

Of(5) Of(0)=1
f(5)<1
Of(3)

Answers

The statements for the function f( x) = 3x ²- 5 are

f( 5)< 1( false)

f( 0) = 1( false)

Statements for the function f(x) = 3x ²- 5

To find the true or false statement we have to substitute the value for x

First, x= 3

f(x) = 3x ²- 5

f(3)= 3( 5)²- 5

f(3) = 75- 5

f(3)= 70.

Thus, the statement" f( 5)< 1" is false.

Now, at x =0

f(x) = 3x ²- 5

f(0) = 3( 0)²- 5

f(0)= 0- 5

f(0)= -5.

Thus, the statement" f( 0) = 1" is false.

Find the volume v of the solid obtained by rotating the region bounded by the given curves about the specified line. y = 2x, y = 2 x , about y = 2

Answers

To find the volume of the solid obtained by rotating the region bounded by the curves y = 2x and y = 2x about the line y = 2, the method of cylindrical shells can be used.

When rotating the region bounded by the curves y = 2x and y = 2x about the line y = 2, we can visualize the resulting solid as a collection of infinitesimally thin cylindrical shells.

The height of each shell is given by the difference between the lines y = 2 and the curve y = 2x, which is 2 - 2x. The circumference of each shell is given by 2πx since the shell is formed by rotating a line segment of length x.

Integrating the product of the height and circumference over the range of x where the curves intersect (from x = 0 to x = 1), we can find the volume of the solid using the formula V = ∫(2πx)(2 - 2x) dx. Evaluating this integral will yield the volume of the solid.

Step-by-step explanation:

From the question, we understand that the top base and the bottom base are directly opposite one another.

When such a scenario arise, it means that the bases have the same shape, they have the same dimension (i.e. size).

With the above analysis, we can conclude that the bases are congruent.

However, the given information can not be used to determine the shape and congruence of the lateral faces.

Lastly, for the bases to be congruent, they must have the same shape (and not any shape).

Answers

If Sam and Tyrone are running on a trail. Sam reaches the 4th mile marker at the same time that Tyrone reaches the 1st mile marker. The number of minutes that  Sam and Tyrone meet is: B) 45 minutes .

How to find the number of minutes?

Speed = Distance/Time  

Sam speed = 1/10 mile/minute

Tyrone speed = 1/6 mile/minute

Time distance covered by Tyrone= (4-1) + x

Time taken= t

Hence,

x/(1/10)   =  (3 + x)/(1/6)

10x  =   6(3 + x)

10x  =  18 + 6x

4x  = 18

x  = 9/2

Time ( t) =x/(1/10)   =  (3 + x)/(1/6)

Time ( t)  =  (9/2)/(1/10)

Time ( t)  = 45 minute

Therefore the correct option is  B.

Answers

Answer:

1/7

Step-by-step explanation:

y = -7x - 1 so slope is -7

The slopes of two perpendicular lines are negative reciprocals of each other

so negative reciprocal of -7 is 1/7

keeping in mind that perpendicular lines have negative reciprocal slopes, let's check for the slope of the equation above

\(y = \stackrel{\stackrel{m}{\downarrow }}{-7}x-1\qquad \impliedby \begin{array}{|c|ll} \cline{1-1} slope-intercept~form\\ \cline{1-1} \\ y=\underset{y-intercept}{\stackrel{slope\qquad }{\stackrel{\downarrow }{m}x+\underset{\uparrow }{b}}} \\\\ \cline{1-1} \end{array}\)

thus a line perpendicular to that slope will have a slope of

\(\rm y = 3.915(1.106)x\) is an expression.

Let x be the day and y be the hold of water.

When pond can hold 400 liters of water the x will be;

400 = 3.915(1.106)ˣ

(1.106)ˣ = 400/3.915    

(1.106)ˣ = 102.17

Taking logarithm on both sides, we get

log (1.106)ˣ = log (102.17)

x log (1.106) = log (102.17)                       [log aˣ = x loga] x = [log (102.17)/log (1.106)]
