how do you calculate mean
Add all the values together then dived by how many numbers there are (the average)
how do you calculate median
middle value (when there are 2 calculate the mean of those values) (add them and divide by 2)
how do you calculate mode
most repeated value
whats the rate of change
The slope value
Whats the inital value
Y-int
what is Z-pattern
Alternate angles are equal
What is F-pattern
corresponding angles are equal
what is C-pattern
co-interior angles add up to 180
what is inscribed angle theorem
the angle between 2 radius is 2 times bigger then the angle between 2 cords if the radius is intersecting
What is Reflex angles
the central angle and the reflex angle they add up to 360 and the central angle is always smaller
improper to mixed
Divide numerator by the denominator for your whole number then keep the denominator then times the whole number and the denominator and have the remainder as your numerator
Mixed to improper
multiply the whole number and the demominator plus add the numertor for your top number and the bottom remains the same
Fraction into percentage
top number divided by bottom number x 100
how to find the percent of a number
put the percent into a decimal and times it by the number for example 25% of 40 would be 40x0.25
when it asks you to express as a single power and your see a division sign what do you do with the exponents
minus them (Quotient law)
when it asks you to express as a single power and your see a multiplication sign what do you do with the exponents
add them (product law)
when it asks you to express as a single power and your see a exponent inside and outside the bracket
multiply them (power law)
What is the value if the exponents are equal to zero
one
what is a coefficient
term beside a variable
what is a constant

what is a Monomial
