Answer 5

letter that represents a number

Question 6

coefficient

Answer 7

the amount of times something happens if you actually do it. the longer you do the experiment, the closer it will be to the theoretical probability.

Question 8

theoretical probability

Answer 8

the number of outcomes using the mathematical way, not actually testing it.

Question 9

prism

Answer 9

a 3D solid figure with two bases that are congruent and parallel.

Question 10

pyramid

Answer 10

a 3D solid figure with one base and sides that meet at a point

Question 11

face

Answer 11

the sides of a geometric solid

Question 12

base

Answer 12

on a pyramid, the base is opposite of the point. on a prism, the base is on off the congruent sides.

Question 13

simplify

Answer 13

writing the expression in its most simple and compact form

Question 14

term

Answer 14

a single mathematical expression

Question 15

like terms

Answer 15

terms that have the same variables and the same exponents (any numbers/constants are considered like terms)

Question 16

constant

Answer 16

any number

Question 17

Question 23

event

Answer 23

some specific outcome of an experiment

Question 24

probability

Answer 24

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.

Answer 26

no equals sign

Question 27

equation

Answer 27

has an equals sign

Question 28

evaluate

Answer 28

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.

Question 29

solve

Answer 29

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.
