No, a statistically significant result would not allow the researchers to conclude that receiving treatments at the clinic selected in part (a-ii) causes a higher percentage of successful treatments than at the other clinic.
The study design is a comparison of the success rates of the two clinics without controlling for any other variables that may influence the results. In order to conclude that the clinic you selected causes higher success rates, the researchers would need to control for other variables, such as the types of treatments, the types of patients, the experience of the clinicians, etc.

The city planner wants to put recycling bins at the circumcenter of the park. What are the coordinates of the recycling bins?.
The coordinates of the recycle bin will be = ( -1, 2.5 )
According to the information given in the question,
The coordinates of the vertices of the park are,
( 1, 1 ), ( 1, 4 ), and ( -3, 4 )
We have to find the coordinates of the recycle bin.
Let us consider the equation of the circle,
[tex]x^{2} +y^{2}+Dx + Ey+ F =0[/tex]
So putting the values of the coordinates into the equation,
First Equation,
[tex]1^{2}+1^{2} + D + E + F = 0[/tex]
Second Equation,
[tex]1^{2} +4^{2} +D + 4E + F=0[/tex]
Third Equation,
[tex](-3)^{2} + 4^{2} - 3D+4E+F=0[/tex]
Subtracting the first equation from the second,
[tex]1^{2} +4^{2} +D + 4E -E=0[/tex]
15 + 3E = 0
3E = -15
E = -5
Subtracting the third equation from the second,
1 + 16 - 9 - 16 + D + 3D = 0
4D = 8
D = 2
Putting the values of E and D in the first equation,
1 + 1 + D + E + F = 0
F = -2 - D - E
F = 1
So now the equation of the circle becomes,
[tex]x^{2} +y^{2}+2x - 5y+ 1 =0[/tex]
By expanding the above equation we can find the standard equation,
[tex]x+2x+1^{2} +y^{2} -5y+ 2.5^{2}- 1^{2} -2.5^{2} +1 =0[/tex]
[tex](x+1)^{2} + (y - 2.5)^{2} = 1^{2} + 2.5^{2} -1[/tex]
[tex](x+1)^{2} + (y - 2.5)^{2} = 2.5^{2}[/tex]
So the required circumcenter will be = ( -1, 2.5 )
Therefore, the coordinates of the recycle bin will be = ( -1, 2.5 )

Exponents:
The way of representing huge numbers in terms of powers is known as an exponent. Exponent, then, is the number of times a number has been multiplied by itself. For instance, the number 6 is multiplied by itself four times, yielding 6 6 6 6. You can write this as 64.In this case, the exponent is 4 and the base is 6. This can be understood as 4 increased to the power of 6.The symbol used for representing the exponent is ^. This symbol (^) is called a carrot. For example, 4 raised to 2 can be written as 4^2 or 42. Thus, 4^2 = 4 × 4 = 16Adding exponents while maintaining the same base is the rule for multiplying like bases.exponents should be multiplied while bases are kept constant when bases are raised by a power of two or more.Division Rule: When dividing like bases, maintain the base constant and deduct the exponent of the denominator from the exponent of the numerator.To know more about Exponents:

If a rectangle and a quare have the ame perimeter then which one will have a larger area
The area of the square is bigger than the Area of the rectangle.
Suppose the sum of all the sides in a square is this: 4 x A and the same is true of a rectangle, too.
Then, first, the area of the square is A^2.
And next, assuming that we have this: 0 < X < A and that one side in the rectangle is this: (A - X)
we can say that the side next to (A - X) is this: (A + X) because the sum of all the four sides in the rectangle has to be this: (4 x A), which equals the sum of all the sides in the square.
So now, the area of the square is this: A^2, whereas the area of the rectangle is this: (A^2 - X^2), which equals this: (A + X)(A - X).
You know thus now, which of the two areas is bigger, and it’s the area of the square. And the difference between the two areas is this: X^2.

three less than twice an integer is greater than 1
2x - 3 > 1
x represents an integer and 3 is less than twice an integer which is 2x. So it's 2x - 3.
2x - 3 is greater than 1.
So therefore, the answer is 2x - 3 > 1
Answer:
2x-3>1
Step-by-step explanation:
lets say x is the interger
so twice an interger would be 2*x or 2x
and three less than that would be 2x-3
and 2x-3 is greater than one
so, 2x-3>1
The size of the standard version is 2.8 megabytes (MB). The size of the high-quality version is 4.3 MB. Yesterday, the high-quality version was downloaded four times as often as the standard version. The total size downloaded for the two versions was 4600 MB. How many downloads of the standard version were there?
Answer:
The number of downloads of the standard version is 230.
Step-by-step explanation:
Let x be the number of downloads of the standard version.
The number of downloads of the high-quality version is 4x.
The total size downloaded for the standard version is 2.8x MB.
The total size downloaded for the high-quality version is 4.3(4x) = 17.2x MB.
The total size downloaded for both versions is 2.8x + 17.2x = 4600 MB.
Combining like terms, we have 20x = 4600 MB.
Dividing both sides by 20, we have x = 230 downloads of the standard version

The term that represents the situation shown in the graphic below is B. a reflection
What is a a reflection?A glide reflection or transflection is a symmetry operation in two-dimensional geometry that combines a reflection over a line with a translation along that line into a single operation.
An exchange of points from one side of a line with points on the other side of the mirror at the same distance from the mirror occurs when a mirror line is fixed in the plane. There is a mirror line in every reflection. A mirror reflection is followed by a translation that is parallel to the mirror to create a glide reflection.
Here, the shape is mirrored in the reflection. A line, called the line of reflection, will allow an image to reflect through it. Every point in a figure is said to reflect the other figure when they are all equally spaced apart from one another.
In conclusion, based on the information given, it should be noted that the correct option is B.

Write an equation in slope-intercept form of the line that passes through (-4, 3) and (-3, 1) .
An equation is
Answer: Y=-2x-5
Step-by-step explanation:
Points: (-4, 3) & (-3, 1)
To find the slope, we use m= (y₂-y₁)/(x₂-x₁)
With these points, m= (1-3)/(-3--4)
This gives us m= -2/1, or -2
Slope-intercept form is y=mx+b
We can plug in the slope now, so y=-2x+b
B is the y-intercept, which is -5, in this case
This gives us y=-2x-5

As per the impact of reducing the tolerable rate of deviation from 7% to 5% on the sample size is 93.
The term deviation is defined as a measure that is used to find the difference between the observed value and the expected value of a variable.
Here we have given that the audit team is planning to examine a sample of control policies and procedures. assume that, based on the intended degree of reliance on internal control, the audit team wishes to control the risk of overreliance to 5%.
And we need to find sample size.
While we looking into the given question, we know that the tolerable rate of deviation from 7% to 5% on the sample size.
Let us consider that 100 be the sample size, then the reduction in 7% to 5%, tell that there is an 2% decrement in the sample size.
Therefore, it can be calculated as,
=> 100 x 2/100

An angle measure 8 less than the measure of its supplementary angle.what is the angle measure of each angle
Step-by-step explanation:
Let the larger angle be x.
Smaller angle = x - 8
As both angles are supplementary,
x + (x - 8) = 180°
2x - 8 = 180°
2x = 188°
x = 94°
Therefore, larger angle = 94°
Smaller angle = 94° - 8° = 86°

Let 'n' be any number, odd or even.
2n will always be even number. This is because, 2n has 2 as common factor. So, 2n is always even.
Eg: 2= 2×1, n=1 ; 4=2×2, n=2 etc
Numbers are even, consecutive.
Consecutive even numbers are 2n-2, 2n, 2n+2,
Eg : For consecutive even numbers, put n=2
2n-2=4-2=2
2n=4
