In this experiment randomization tends to minimize the effects of uncontrolled variables, such as water temperature, so that such factors are not confounded with the treatment effects.
In an experiment, variables are carefully controlled in order to ensure the reliability of the results. Usually, treatments are assigned randomly to experimental units. Randomization refers to the assignment of experimental units to groups by chance.
Randomization is important in this experiment because it tends to minimize the effects of uncontrolled variables, such as water temperature, so that such factors are not confounded with the treatment effects.

In triangle def, cg = (x + 5) units and dg = (3x - 2) units. [figure may not be drawn to sacle] what is dg? 12 units 17 units 34 units 51 units.
The length of the segment DG is 34 units
How to determine the length DG?The attached figure represents the missing information in the question
The point G is the centroid of the triangle.
This means that:
CG : DG = 1 : 2
Express as fraction
CG/DG = 1/2
Multiply both sides by 2
DG = 2 * CG
Substitute the given parameters:
3x - 2 = 2 *(x + 5)
Expand
3x - 2 = 2x + 10
Evaluate the like terms
x = 12
Recall that:
DG = 3x - 2
So, we have:
DG = 3 * 12 - 2
Evaluate
DG = 34
Hence, the length DG is 34 units

What is the measure of arc BEC in circle D? 134° 150 209° 210°.
Answer:
134°
Explanation:
The measure of arc BEC in circle D is 134°. The correct option is 1.
What is circle?A circle is a closed two-dimensional figure in which the set of all the points in the plane is equidistant from a given point called "centre".
The line of reflection symmetry is formed by every line that passes through the circle.
We've been given a circle image and asked to calculate the measure of arc BEC.
That angle is visible to us. ABC is an inscribed angle, and its measure is one-half the length of its subtended arc.
Here,
AC = 2 x m∠ABC
AC = 2 x 75°
AC = 150°
We can set an equation to find the measure of arc BEC because we know that the circumference of a 360 degree is:
Arc BEC + Arc AB + Arc AC = 360°
Arc BEC + 76° + 150° = 360°
Arc BEC + 226° = 360°
Arc BEC = 134°
Thus, the answer is 1.

What mass of glucose (C6H12O6) should be dissolved in 10. 0 kg of water to obtain a solution with a freezing point of -4. 2 ∘C?.
Answer:
4.1kg
Explanation:
I dont kwon but it was ok in the test
The mass of glucose dissolved in the solution is obtained as 4.734 Kg.
We know that;
ΔT = K m i
ΔT = Freezing point depression
K = freezing constant = 1.86 °C/m
m = molality of solution
i = Van't Hoff factor = 1 (molecular solution)
To find the freezing point depression;
Freezing point depression = Freezing point of pure solvent - Freezing point of solution
Since freezing point of water = 0°C
Freezing point depression = 0°C - (-4. 2 ∘C) = 4. 2 ∘C
The molality of the solution is obtained as follows;
m = ΔT/K i
m = 4. 2 ∘C/ 1.86 °C/m × 1
m = 2.63 m
Molality = number of moles/mass of solvent in Kg
Number of moles = mass/molar mass =
Molar mass of glucose = 180 g/mol
Let the mass of solute be m
2.63 = m/180/10
2.63 = m/1800
m = 2.63 × 1800
m = 4734 g or 4.734 Kg

A car is traveling with a constant speed when the driver suddenly applies the brakes, causing the car to slow down with a constant acceleration of magnitude 3. 50 m/s2. If the car comes to a stop in a distance of 30. 0 m, what was the car's original speed?.
Answer: 14.49 m/s
Explanation: you would have to use kinematic equations to solve for the original speed.
v^2 = v0^2 + 2 (a) (x) where v = 0 since the car stopped
then you would get v0 = sqrt (2(a)(x))
plug in the known values
v0 = sqrt(2(3.50)(30.0))
v0 = 14.49 m/s
So the answer would be 14.49 m/s
