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.

Answer:

Step-by-step explanation:

y=l2−16k−4

Step 1: Flip the equation.

l2−16k−4=y

Step 2: Add -l^2 to both sides.

l2−16k−4+−l2=y+−l2

−16k−4=−l2+y

Step 3: Add 4 to both sides.

−16k−4+4=−l2+y+4

−16k=−l2+y+4

Step 4: Divide both sides by -16.

−16k

Domain: [tex]x \ge 0[/tex]

Domain in interval notation:   [0, infinity)

This is because the domain is the set of all allowed x inputs. In this case, x = 0 is the smallest and we include this endpoint. Any x value x = 0 or larger is part of the domain (since the graph stretches' on forever to the right)

--------------------------------------------------------------------

Range:  [tex]y \ge 2[/tex]

Range in interval notation:   [2, infinity)

For similar reasoning as the domain, but now we consider the possible y output values. Here y = 2 is the smallest and we include it. Note the square bracket for interval notation means "include this endpoint". The curved parenthesis means "exclude this endpoint"

Answer:

306

Step-by-step explanation:

18x17=306

The total number of matches played by the teams will be given by using permutation is 306.

A permutation is an act of arranging the objects or elements in order. Combinations are the way of selecting objects or elements from a group of objects or collections, in such a way the order of the objects does not matter.

There are 18 football teams in a league.

Each team plays two matches against each of the other teams.

Then the total number of matches played by the teams will be given by the permutation.

[tex]^{n}P_r = \dfrac{n!}{(n-r)!}[/tex]

We have

n = 18

r = 2

Then

[tex]\rm ^{18}P_2 = \dfrac{18!}{(18-2)!}\\\\\\^{18}P_2 = \dfrac{18!}{16!}\\\\\\^{18}P_2 = \dfrac{18 *17*16!}{16!}\\\\\\^{18}P_2 = 18*17\\\\\\^{18}P_2 = 306[/tex]

Answer:

Just search it up. The answer is 1800

Step-by-step explanation:

Type.

Or there's another way.... you multiply if you want to convert a unit that is greater to smaller, and you divide if you want to convert a smaller unit to a larger one.

For example hours to minutes:

You cross out the word that matches. Here it's hour.

3.15 hours X 60 min/1 hour=189 min

189min X 60 sec/1min=11340 sec

and if it's from smaller to greater you divide, get it?

Answer:

C. ∠10

Explanation:

A theorem states that the two angle that are in the same side and are opposite to each other, they add up to 180°, which is supplementary.

Step-by-step explanation:

In the rational fraction (x - 4)/(x² + 2x - 24),

x² + 2x - 24 is the denominator.

When x² + 2x - 24 = 0, (x + 6)(x - 4) = 0.

=> x = -6 or x = 4.

The excluded values for x are -6 and 4.

Explanation:

The given equation is the same as (x-4)^2 + (y-0)^2 = (sqrt(90))^2

It is in the form (x-h)^2 + (y-k)^2 = r^2

We have the following

The center is (h,k) = (4,0) and the radius is sqrt(90) units

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].

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.

Answer:

(1) The slope of the line having y = 5 as its equation is zero ⇒ (C)

(2) The slope of the line having x = -4 as its equation is undefined ⇒ (B)

Step-by-step explanation:

Let us use the rules above to solve the question

(1)

∵ The equation of the line is y = 5

→ That means the line is horizontal

∴ The line is a horizontal line

∵ The slope of the horizontal line = zero

∴ The slope of the line having y = 5 as its equation is zero

(2)

∵ The equation of the line is x = -4

→ That means the line is vertical

∴ The line is a vertical line

∵ The slope of the vertical line is undefined

∴ The slope of the line having x = -4 as its equation is undefined
