The answer is C.

you do the inverse of positive 15, which is negative 15. so put it on both side .

10x +15 =20
-15 =-15

to equal

10x =5

then divide 10 on both side

10x = 5
----- -----
10 10

x = 5/10 or 1/2

Answer:

Option (A)

Step-by-step explanation:

There are 2 main branches of statistics. They are:

1. Descriptive Statistics

2. Inferential Statistics

Descriptive statistics describes the characteristics of observed subjects or items while Inferential statistics makes inferences, based on given or derived data.

Inferential Statistics allow you to decide whether a difference between the experimental group and control group is due to manipulation or chance.

The Experimental group is the group that an effect is tested on while the Control group is the group that is left untested or uninfluenced. Inferential statistics allow you to decide whether a difference between these 2 groups is due to

- manipulation or interference by any force (which may be the experimenter/researcher)

- probability which is chance.
