The scenario exemplifies a(n) that effect is practice effect
In experiments utilising within-subjects designs, the practise effect is especially problematic since participants' performance on the study variable may increase just by engaging in the activity again, independent of any study manipulations the researcher may have imposed.
When a test is retaken, the practise effects have an impact on the results. A practise effect, for instance, can result from taking numerous practise SAT exams; practise can raise your overall score.
Counter balancing is one strategy for limiting the effects of practise. It is possible that the trials will use randomization or will use every feasible order for administering treatments to subjects.

(x -1)2 = y - 4 is the vertex form of the equation Y = X² - 2x + 5.
What is the vertex form?A quadratic function has the vertex form f(x) = a(x - h)2 + k, where a, h, and k are constants.
Obtain the equation y = ax2 + bx + c.
Determine -b / 2A.
The vertex's x-coordinate is given here.
Simply enter the value of -b / 2a into the equation for x and solve for y to obtain the vertex's y-coordinate.
The vertex's y-coordinate is given here.
So, we have the equation:
Y = X² - 2x + 5
Now, calculate as follows:
⇒ y = (x2 - 2x + 1) + 5 -1

Om = 15
Om = 16
The value of m in the triangle XYZ is 16. option D
How to determine the valueIt is important to note that the sum of angles in a triangle is 180 degrees.
From the information given, we have that;
Angle MZ is the exterior angle = (5m - 15)Angle Z is the interior angle = 7m + 3Then we have that;
Angle MZ + Angle Z = 180
Now, substitute the values into the formula, we have;

expand the bracket
5m - 15 + 7m + 3 = 180°
collect like terms
12m - 12 = 180°
12m = 180 + 12
Add the like terms
12m = 192
Make 'm' the subject of formula by dividing both sides by 12, we get;

= (0.8691) × [tex]\sqrt{\frac{30 - 2}{0.1309^{2} } }[/tex]
t = 9.2974
we know that degree of freedom = n - 2 = 28
p-value at t = 9.2974 is 0.00
α = 0.05
since p-value < α
so null hypothesis will be rejected.
Hence we can say that there is sufficient evidence that revenue and the number of downloads are linearly related.

A rainwater system is structured as shown. The radii are the same for both rain barrels. The shorter rain barrel has a height equal to its radius. The
taller rain barrel has a height twice its radius. The total surface area for both barrels with no top is about 40,212 square centimeters.
The radius is 1,264 cm
What is the total Surface Area of Cylinder ?The area of the two circular bases and the area of the curving surface together make up the cylinder's total surface area. The area of the circular top and base, as well as the curved surface area, are included in the overall surface area (CSA).
According to the given information
Let radius = r
Height of shorter rain barrel [tex]h_{1}[/tex] = r
Height of taller rain barrel [tex]h_{2}[/tex] = 2r
We know that
Each Barrel is a cylinder without top
So
Total Surface area for each = 2[tex]\pi[/tex]rh + [tex]\pi[/tex][tex]r^{2}[/tex]
TSA for both Barrels = [tex]2\pi rh_{1} + \pi r^{2}+ 2\pi rh_{2} + \pi r^{2}[/tex]
= [tex]2 \pi r^{2} + 2\pi r^{2} + 4\pi r^{2}[/tex] ( put [tex]h_{1}[/tex] = r , [tex]h_{2}[/tex] = 2r )
= [tex]8\pi r^{2}[/tex]
r = [tex]\sqrt{\frac{TSA}{8\pi } }[/tex]
Total surface area is 40 ,212 [tex]cm^{2}[/tex]
r = [tex]\sqrt{\frac{40,212}{8\pi } }[/tex]
So
The radius is 1,264 cm
