Measures of Central Tendency
It is the average obtained by adding all the values and dividing the sum by the number of values.
Mean

What does FOIL stand for?
F- First Term
O- Outer term
I - Inner Term
L- Last term

Median
What must remain the same when like terms are combined?
Variable and exponent
What is the error in the statement x⁴ · x³ = x¹²?

What two middle terms are obtained when multiplying (x+5)(x+2)?
2x and 5x
What special product pattern is used in (x − 3)(x + 3)?
Sum and Difference of Two Binomial
Trimodal
Why can 7x + 4 not be simplified into a single term?
They are not like terms and cannot be combined.
What is the simplified form of x³ ÷ x⁵?
1/x2
What property explains why every term in one binomial must be multiplied by every term in the other binomial?
Distributive property
What is the product of (4x+3)(4x−3)?
16x2-9
A student claims that the median is always equal to the mean. What is the best reason this statement is incorrect?
The Median: Calculates the average of all values. It is highly sensitive to extreme outliers and data distribution.
The Median: Finds the exact middle value of an ordered dataset.
A rectangle has a length of 3x + 2 and a width of x + 4. What algebraic expression represents its area?
3x2+14x+8
A student writes 3x2 . 4x3 = 7x5, what is the error?
The student added the coefficients instead of multiplying them.
What should be done to the resulting like terms after multiplying two binomials?
Simplify or Combine the resulting like terms by adding or subtracting their coefficients to simplify the expression into a standard polynomial.
