18
Q

radius

A

straight line from the center to the circumference of a circle

19
Q

diameter

A

straight line passing from side to side through the center of a circle

20
Q

circumference

A

the distance around a circle

21
Q

pi

22
Q

sample space

A

the set of all possible outcomes in an experiment

23
Q

event

A

some specific outcome of an experiment

24
Q

probability

A

a number between 0 and 1 inclusive that represents the extent of an event happening. an event that cannot occur has a probability equal to 0. the probability of an event that is certain to occur has a probability equal to 1.

25
Q

certainty

A

an event that is definitely going to take place.

26
Q

expresssion

A

no equals sign

27
Q

equation

A

has an equals sign

28
Q

evaluate

A

to evaluate an expression, you substitute the given value for the variable using parenthesis and then follow the order of operations. the answer will be a single numerical answer.

29
Q

solve

A

to solve an equation, isolate the variable by undoing the operations that are being done to it. the answer will be a variable (a numerical answer (usually, but not always) that, when substituted would make the equation true.

30
Q
