What is the solution to the equation 2x + 6 = 14?
Answer: x = 4
Subtracting 6 from both sides gives 2x = 8, then dividing by 2 yields x = 4.
What is the slope of the line described by the equation y = 3x - 7?
Answer: 3
In slope-intercept form y = mx + b, the coefficient m of x is the slope, which is 3.
Which of the following represents a quadratic equation?
Answer: y = x² + 5x - 6
A quadratic equation has a degree of 2, meaning the highest power of the variable is 2, as in x².
What is the value of 5! (5 factorial)?
Answer: 120
5! = 5 × 4 × 3 × 2 × 1 = 120.
Which measure of central tendency is most affected by outliers?
Answer: Mean
The mean uses all values in its calculation, so extreme outliers can pull it significantly higher or lower.
What is the probability of rolling a 4 on a standard six-sided die?
Answer: 1/6
There is one favorable outcome (rolling a 4) out of six equally likely outcomes, giving a probability of 1/6.
