School-aged children are regularly asked to fundraise for their school. typically, they are required to sell a minimum amount. this mandate results in most students selling that minimum, with some exceptional children selling far larger quantities. the minimum sales constraint that likely causes positively skewed data is consistent with a effect.

The answer is floor effect.

Step-by-step explanation:

The minimum sales constraint that likely causes positively skewed data is consistent with a floor effect.

In the field of research, a floor effect happens when measurements of the dependent variable result in very low scores on the measurement scale.

Note : A dependent variable is that variable, which is exposed to the independent variable and then measured.

answer: (-8,4) are the coordinates of a

step-by-step explanation:

let the side of square abcd is x .

thus the area of square abcd is .

now, by the diagram area of triangle ead= 1/2 × ea × ad = 1/2 × ea × x

( because ad is the side of square)

and, according to the question,

the areas of square abcd and right ead are equal.

⇒

⇒ea=2x

thus, ea: ab=2: 1

therefore, point a divides line segment eb into the ratio 2: 1.

⇒ by sectional formula coordinates of a are,

=

=

=(-8, 4)

thus the coordinates of a are (-8,4)

slope =   (y2 -y1) ÷ (x2 -x1)

slope = (0 -0) / (-5, -7)

slope = 0 / -12 = 0

the slope of the line is zero.   it is perfectly horizontal.
