Determine whether the study described is a randomized experiment or an observational study. a wellness instructor wants to determine the effect of fitness class types on body fat composition. she measures the body fat of 100 fitness class participants before randomly assigning the participants to a class of yoga, zumba, pilates, or tae bo. she measures the body fat of each participant during the last week of classes. choose the correct answer o randomized experiment o observational study

Observational study

Step-by-step explanation:

Observational study is a research taken to get an inference or conclusion on a particular study.

A wellness instructor wants to determine the effect of fitness class types on body fat composition. the 100 participants are randomly assign to different class of yoga and there performance are noted.

the performance of the participant will be used to draw an inference on the effect of different fitness class on body weight.

the correct answer to your question is a. 4^4

good luck my friend!

hope this !

maybe if i you could me by giving me brainliest?

have a splendid day < 3 : )

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)
