Which of the following are reasons for performing experiments?

A. to measure variables of interest without influencing the responses.
B. to determine if a particular treatment has a desired effect on the response variable.
C. to overcome ethical difficulties that observational studies could potentially present.
D. to establish a cause-and-effect relationship between the treatment and the response.
E. to identify the effects of a lurking variable on the response variable.

typically if you want , you would actually put questions here for us to you. but hey, that's just me. maybe someone will magically answer the questions for you without knowing what they are.

50*10 is greater

step-by-step explanation:

if you add the zero from 10 to 50, it will give you a bigger number.

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.

on a coordinate grid, point a is at (−4.0, −2.4) and point b is at (4.0, −2.4). point b is a reflection of point a across the –axis. input either a lowercase x or i think is the right awnser
