A dance student wants to know the favorite type of dance class for students at The Dance Academy. She surveys each student in her ballet class. In which way could the results of her survey be most improved? She could sample an equal number of students in each type of dance class.
She could sample a proportional number of students in each type of dance class.
She could sample one student in each type of dance class.
She could sample one teacher from each type of dance class.
Mark this and return

A. She could sample an equal number of students in each type of dance class.

Step-by-step explanation:

The answer is A. because all the other ones are not equal, and some are leaned more towards one side.

Hope this helps! :)

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)
