The control group in the experiment are the classes where the teacher does not greet the students

A control group in an experiment is made up of groups of people that do not receive the experimental treatment.

The purpose of a control group is to allow the researcher study one variable at a time.

Victor is conducting an experiment on if positively greeting children as they enter the classroom reduces problem behaviours.

The experimental treatment here is positively greeting the students.

The group that do not receive this experimental treatment are referred to as the control group.

At the end of the experiment, Victor would compare the behaviours of the students in the control group with the behaviour of those who were part of the experimental group to see if greeting reduced problem behaviours.

Answer:  x = 0; y = 2; z = 5

Step-by-step explanation:

x+2y+z=9

x-y+3z=13

2z=10

==

Start with the last equation:  2z = 10, therefore z = 5 [easy]

Let's rewrite the second equation with 1) z=5, and 2) rearrange to find x:

x-y+3z = 13

x - y +3*5 = 13

x = y-2

Now use the values for x [(y-2)] and y [5] in the first equation:

X+2y+z=9

(y-2) +2y + 5 = 9

3y +3 = 9

3y = 6

y = 2

Now that we have y [2] and z [5], let's use the first equation to solve for x:

x+2y+z=9

x + 4 + 5 = 9

x + 9 = 9

x = 0

====

Try the three values (x=0, y=2, and z=5) in any of the formulas.  The result should/will equal the number shown.

Answer:

$22.33

Step-by-step explanation:

A 20% tip would be 0.20. Multiply the cost by 0.20 to get the tip amount or multiply the cost by 1.20 to get the total amount including tip.

subtotal --> $18.61

tip --> $3.72

18.61 x 0.20 = 3.72

total --> $22.33

2(3x + 7) + (2x - 3) =

= 6x + 14 + 2x - 3 =

= 6x + 2x + 14 - 3 = 8x + 11 ← the end

[tex](a+b)(a-b)=a^2-b^2\\\\(4+2i)(4-2i)=4^2-(2i)^2=\boxed{16-4i^2}[/tex]

Answer:

A

Step-by-step explanation:

We want to simplify the expression:

[tex](4 + 2i)(4- 2i)[/tex]

Notice that this is the difference of two squares. That is:

[tex](a +b)(a-b) = a^2 - b^2[/tex]

We can let a = 4 and b = 2i. Hence:

[tex](4+2i)(4-2i) = (4)^2 - (2i)^2[/tex]

Simplify:

[tex]= (16) - (4i^2) \\ \\ = 16 - (-4) \\ \\ = 20[/tex]

(Note that i² = -1.)

In conclusion, our answer is A.

The value of x is 108.

The highest common factor is defined as the set of numbers with the highest common multiple. The highest positive integer with more than one factor in the set is HCF.

Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions.

* Multiplication operation: Multiplies values on either side of the operator

For example 4*2 = 8

We have been given that the HCF of 90 and x is 18.

And the LCM of 90 and x is 540.

We have to determine the value of x.​

Since the product of two numbers equals the product of their HCF and LCM.

So 90 × x= HCF × LCM

Substitute the values of given data,

⇒ 90×x = 18×540

⇒ 90×x = 9720

⇒ x = 9720/90

⇒ x = 108

Hence, the value of x is 108.

i could be wrong but i did it in my head , but the equation is right . just do that in order

Answer:

( 0.5, - 1 )

Step-by-step explanation:

So here is the equation:

x2 + x1 / 2 For the x coordinate

y2 + y1 / 2 For the y coordinate

x2 is 4 and x 1 is -3 whilst y2 is 2 and y1 is -4.

Thus:

4 + -3 / 2 = 0.5 x coordinate

2 + -4 / 2 = -1 y coordinate

So it becomes (0.5, -1)
