Type the correct answer in the box. ally surveyed 5 classrooms. she wanted to know the number of students in each class who love painting. the data she collected from the 5 classrooms is below. 10, 7, 9, 11, 8 the value that could be the best measure of the center of this data is ?

A graph

Step-by-step explanation:

greater than one

step-by-step explanation:

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)
