If an independent-measures design is being used to compare two treatment conditions, then how many different groups of participants would be needed and how many scores would there be for each participant

Answers

Answer:

2 groups and 1 score for each participant

Step-by-step explanation:

An independent measures design is a defined as a research method whereby multiple experimental groups are examined and the participants will only be in one group. Now, each participant will only be affected by one condition of the independent variable during the experiment.

In the question given, we want to use the method I just described to compare two treatment conditions.

This means that there will be two groups and each participant in both groups will be assigned one score.

The length of a rectangle is (x^2- 4x+2) feet and the width is (x+4) feet

Answers

Answer:

[tex]A=x^3-14x+8[/tex]

Step-by-step explanation:

Given that,

Length of a rectangle, [tex]l=(x^2- 4x+2)[/tex]

Width of a rectangle, [tex]b=(x+4)[/tex]

We need to find the area of the rectangle.

We know that,

Area of a rectangle = l × b

Substituting all the values,

[tex]A=(x^2- 4x+2)\times (x+4)\\\\=x^3+4x^2-4x^2-16x+2x+8\\\\=x^3-14x+8[/tex]

Hence, the area of the rectangle is [tex]x^3-14x+8[/tex].

Ella is going to drive from her house to city a without stopping. Ella’s house is 100 miles from city a and after driving three hours she will be 25 miles away from city a. Writing equation for D in terms of T represent an LS distance from city a T hours

Answers

Answer:
d = 100 - 25t

Step-by-step explanation:

Let's use basic logic here.
If we are 100 miles away from a place, and we've got 25 miles to go, we've already travelled 75 miles.
Since we've travelled 75 miles in 3 hours, then we travel at a rate of 75 divided by 3 = 25 miles per hour.

The distance to City A will be represented as 100 - miles already travelled. We can find how many miles have been travelled by multiplying 25 by t, the amount of hours we've spent driving.

This creates the equation d = 100 - 25t

Step-by-step explanation:


1,a) Find a recursive formula for the sequence 1, 2, 6, 24, 120, . . . .

b) Find the sixth and the seventh terms of the sequence.
​

Answers

a) The n-th term in the sequence is the product of the first n natural numbers:

1 • 2 = 2

1 • 2 • 3 = 6

1 • 2 • 3 • 4 = 25

1 • 2 • 3 • 4 • 5 = 120

and so on. Recursively, the n-th term is a function of the (n - 1)-th term as

a(n) = n a(n - 1)

b) Using the rule above, the 6th and 7th terms are

a (6) = 6 a (5) = 6 • 120 = 720

and

a (7) = 7 a (6) = 7 • 720 = 5040

We want to find a recursive formula for the given sequence and then find the next terms in the given sequence.

the solutions are:

a) Aₙ = n*Aₙ₋₁

b) A₆ = 720 and A₇ = 5,040

We start with the sequence:

1, 2, 6, 24, 120, ...

a) Let's find the recursive formula.

If Aₙ represents the n-th term in the sequence, then we have:

A₁ = 1

A₂ = 2 = 2*1 = 2*A₁

A₃ = 6 = 3*2 = 3*A₂

A₄ = 24 = 4*6 = 4*Aₐ

A₅ = 120 = 5*24 = 5*A₄

So we can see the pattern, the recursive formula is just:

Aₙ = n*Aₙ₋₁

b) We want to find the sixth and the seventh terms of the sequence, we can use the recursive formula we got above.

A₆ = 6*A₅ = 6*120 = 720

A₇ = 7*A₆ = 7*720 = 5,040

The sixth term is 720 and the seventh term is 5,040

Find the value of x in the figure below.
(8x + 5)°
(13x – 14)°

Answers

Answer:

x = 9

Step-by-step explanation:

The question is shown in the attached figure.

We can see that, (8x + 5)°  and (13x – 14)° forms a linear pair. It would mean that,

(8x + 5)° + (13x – 14)° = 180°

21x-9 = 180°

21x = 180° + 9

21x = 189

x = 9

Hence, the value of x is 9.

What is 54% of $789.56

Answers

Answer:

$426.36

Step-by-step explanation:

0.54 * 789.56 = 426.3624

hope this helps, pls mark brainliest :D

If you take 54% of the amount of $789.56, the resulting value would be $426.83.

As we know that percentage is a ratio that is stated as a fraction of 100.

To determine 54% of $789.56, we follow these steps:

Convert 54% to decimal form by dividing it by 100.

54% = 54 ÷ 100 = 0.54

Multiply the decimal value (0.54) by the dollar amount ($789.56).

0.54 × $789.56 = $426.8324

Round the result to two decimal places.

Rounding $426.8324 to two decimal places gives us $426.83.

Therefore, 54% of $789.56 is approximately $426.83.

This means that if you take 54% of the amount of $789.56, the resulting value would be $426.83.
