Answer:

The groups of subjects are similar, on average, in all respects before applying the different treatments to the different groups

Step-by-step explanation:

Randomization is a technique employed by researchers, which seeks to measure the effect of a treatment on a particular variable. The group is divided into the control and treatment groups. Treatment is administered to each group, and the effect is compared between them. The most important value of randomization is that it ensures that the groups who would be receiving treatments are similar on average to prevent bias caused by systematic differences. It also helps to ensure that each participant in the study has an equal chance of being selected for the study thus eliminating selection bias.

Randomization ensures that both participants and researchers do not have prior knowledge of the experiment which might influence their response to treatment.

Find​ f(x) and​ g(x) such that ​h(x)equals​(fcircle​g)(x). h left parenthesis x right parenthesis equals left parenthesis 2 x pl
GaryK [48]

Answer:

  • f(x) = x^3
  • g(x) = (2x+4)^2

Step-by-step explanation:

There are many ways to decompose h(x) into f(x) and g(x). The main purpose of the exercise seems to be to get you to think about the operations that are performed on x, then divide that list of operations into two parts.

In the function ...

  h(x) = (2x +4)^6

the variable x is ...

  • multiplied by 2
  • 4 is added to the sum
  • the sum is raised to the 6th power

Of course, the 6th power can be considered as the cube of a square or the square of a cube, if you like.

In the decomposition shown in the answer above, we have chosen to put most of this list in g(x), including the square of the sum. Then we have made f(x) be the cube of that square.

  h(x) = f(g(x)) = (2x+4)^6

When f(x) = x^3, this is ...

  h(x) = f(g(x)) = g(x)^3 = ((2x+4)^2)^3

so ...

  g(x) = (2x+4)^2 . . . and . . . f(x) = x^3

_____

Other possible decompositions are ...

  • g(x) = 2x
  • f(x) = (x+4)^6

or

  • g(x) = (x+2)
  • f(x) = (2x)^6

or

  • g(x) = 2x+4
  • f(x) = x^6

or ... (many others)

Write 43 as a sum of powers of 2.<br> (2 Has to be the Base not the exponent)
slamgirl [31]

Answer:

2⁰ + 2¹+ 2⁵ +2³ = 43

Step-by-step explanation:

since 43 is odd, we know 2⁰ or 1 must be one of the sums

43 - 2⁰ = 42

42 - 2¹ = 40

16 = 2⁴

40-2(16) = 40 - 2⁵ = 8

8 = 2³

adding this all together

2⁰ + 2¹+ 2⁵ +2³ = 43

The circumference of a circular garden is 141 feet. What is the radius of the garden?
evablogger [386]

Answer:

r ≈ 22.44 ft

Step-by-step explanation:

The circumference (C) of a circle is calculated as

C = 2πr ( r is the radius ), then

141 = 2πr ( divide both sides by 2π )

\frac{141}{2\pi } = r , that is

r ≈ 22.44 ft ( to the nearest hundredth )
