Can someone help me figure out how to get the answer for these like step by step?
Equations and Inequations
Equations and inequalities describe the relationship between two mathematical expressions.
Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
The empirical rule is also referred to as the three-sigma rule or 68-95-99.7 rule. It states that almost all observed data will fall within three standard deviations () of the mean or average ().
The empirical rule predicts that 68% of observations falls within the first standard deviation , 95% within the first two standard deviations (, and 99.7% within the first three standard deviations (.
