In order to maximize the chances that experimental groups represent the population of interest, researchers should conduct ________ and ________. blind sampling; random group assignment blind group assignment; random sampling random sampling; random group assignment blind group assignment; blind sampling

Answers

In order to maximize the chances that experimental groups represent the population of interest, researchers should conduct  random sampling and random group assignment

Explanation:

The terms Random sampling and Random group assignment are greatly different in process of the sample selection.  The study related to the determination of how sample participants can be drawn from the population refers to the process of Random sampling. The sample participants are subjected to a treatment by the usage of a random procedure comprises the Random group assignment.

When a researcher wants validate externally then random selection can be used. When a researcher wants to determine the effects of treatment within that group which is known as determination of internal validity then he can opt for Random group assignment.

Answer:

In order to maximize the chances that experimental groups represent the population of interest, researchers should conduct random sampling/random group assignment.

Explanation:

Random selection is a representation of the sample of people for your research from a community. Random assignment is the assigning of the sample that describes various groups or operations in the study.

Reasons:

  • Random sampling enables us to get a sample representative of the community.
  • Random assignment enables us to make positive that the only distinction among the various treatment combinations is what needs to study.
  • Random assignment is crucial for sound empirical design. With adequately large representations, random assignment performs it unlikely that there are methodical variations among the groups.

Thus we can say in order to maximize the chances that experimental groups represent the population of interest, researchers should conduct random sampling/random group assignment.

Pat and his friend rent an apartment together. Their total cost to move in included first months rent, last months rent and a security deposit of $600. If Pat paid a total of $1,050 to move in, how much is his share of the rent each month?a.
$375
b.
$450
c.
$525
d.
$750

Answers

Answer:

a.$375

Step-by-step explanation:

In order to calculate this you just have to keep in mind the amount of months that they paid in advance in the payment, so they had 2 months of rent fully paid in advance, we will represent that with "x", so we have 2x as the number of months, and it doesn´t say that they are paying unequal amounts of money so we will assume that they are paying half each of everything, so the equation will look like this:

Total payment: 2 months of rent+security deposit

If total payment= $1050 each, that means that for the two of them it´d be $2100, now we know that they paid 2 months plus a security deposit of $600, we just have to clear the payment to discover how much does the rent a month cost:

Total payment: 2 months of rent+security deposit\nTp=2x+600\nTp-600=2x\nx=(Tp-600)/(2) \nx=(2100-600)/(2) \nx=750

So one month of rent costs $750, if you divide that by 2, you get that Pat´s share of rent a month is $375.

Which expression is eqivalent to (x^2-3x)(4x^2+2x-9)

Answers

For this case we must find an expression equivalent to:

(x ^ 2-3x) (4x ^ 2 + 2x-9) =

We apply distributive property, term by term, taking into account that:- * + = -\n- * - = +\nx ^ 2 * 4x ^ 2 + x ^ 2 * 2x-x ^ 2 * 9-3x * 4x ^ 2-3x * 2x + 3x * 9 =

By definition we have to, to multiply powers of the same base, the same base is placed and the exponents are added:

4x ^ 4 + 2x ^ 3-9x ^ 2-12x ^ 3-6x ^ 2 + 27x =

We add similar terms taking into account that:

Equal signs are added and the same sign is placed.

Different signs are subtracted and the major sign is placed.

4x ^ 4-10x ^ 3-15x ^ 2 + 27x

Answer:

An equivalent expression is: 4x ^ 4-10x ^ 3-15x ^ 2 + 27x
