Three times a number:
Four times a number:
Two-thirds of a number
Let
n ----> the number
Part 1) we have
Three times a number:
we know that
The algebraic expression is equal to multiply 3 by the number n
so
Part 2) we have
Four times a number:
we know that
The algebraic expression is equal to multiply 4 by the number n
so
Part 3) we have
Two-thirds of a number
we know that
The algebraic expression is equal to multiply the fraction 2/3 by the number n
so
Answer:
C. Predicts someone's blood alcohol level from the number of whiskey drinks they consumed.
Step-by-step explanation:
In Statistics, classification problems are differentiated from estimation problems because classification problems typically requires that the output attribute be categorical while estimation problems require that the output attribute is numerical. In an estimation problem, the output variable has a continuous or real value, such as predicting the size, area, weight, age or even the cost of an item.
A Classification problem work with the concept of creating a succinct model such as decision trees, Naive Bayes, random forest, logistic regression, etc, which is capable of predicting from the attribute (observed) variables given; values of the dependent attribute, which is always categorical.
In order to predict a dichotomous variable from a given data set comprising of continuous or dichotomous variables, a logistic regression can be used.
Mathematically, it is given by the expression;
Logistic regression with
,
........
Where;
y represents the dichotomous dependent variable.
,
........
represents the predictable variables, which are categorical in nature such as alive or dead, win or lose, sick or healthy, pass or fail, etc.
Hence, a regression would be appropriate for predicting someone's blood alcohol level from the number of whiskey drinks they consumed.
