Answer:
Its c. c = 50.
Step-by-step explanation:
First, we need to figure out what the equation equals.
7 + 7/7 + 7*7 - 7 = x
PEMDAS
Parentheses, exponents, division/fraction, addition, subtraction.
7/7 = 1. So equation changed into 7 + 1 + 7*7 - 7 = x.
7*7 = 49. So equation changed again into 7 + 1 + 49 - 7.
Lets calculate it. 7 + 1 = 8 + 49 = 57 - 7 = 50. x = 50.
c is the only one who has a calculation of 50.
Answer:
<u>-The independent variable is whether the motivational signs were posted, and the dependent variable is the amount of use of the stairs.</u>
<u>-Nominal scale. </u>
Step-by-step explanation:
<u>Independent variable:</u> In research methods, the term "independent variable" is described as the variable that is being altered, manipulated, or changed by an investigator to see its effects on the dependent variable in specific research or experiment.
<u>Dependent variable: </u>In research methods, the term "dependent variable" is described as the variable that is being measured, analysed, or tested in an experiment by the experimenter or researcher. The dependent variable is being directly affected by the independent variable.
<u>Nominal scale:</u> In research methods, the term "nominal scale" is determined as one the different measurement scales in which a specific number is being served as labels or tags only and to classify and identify an object.
Step-by-step explanation:
SSS
SSS stands for "side, side, side" and means that we have two triangles with all three sides equal. For example: is congruent to: (See Solving SSS Triangles to find out more) If three sides of one triangle are equal to three sides of another triangle, the triangles are congruent
SAS
The Side Angle Side postulate (often abbreviated as SAS) states that if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then these two triangles are congruent.
ASA
ASA stands for "angle, side, angle" and means that we have two triangles where we know two angles and the included side are equal. For example: is congruent to: (See Solving ASA Triangles to find out more)
AAS
The Angle Angle Side postulate (often abbreviated as AAS) states that if two angles and the non-included side one triangle are congruent to two angles and the non-included side of another triangle, then these two triangles are congruent.
