Use this to predict the number of situps a person who watches 8.5 hours of TV can do (to one decimal place)
Percentage
A percentage is a number indicated as a fraction of 100. It is a dimensionless number often expressed using the symbol %.
Algebraic Expressions
In mathematics, an algebraic expression consists of constant(s), variable(s), and mathematical operators. It is made up of terms.
Numbers
Numbers are some measures used for counting. They can be compared one with another to know its position in the number line and determine which one is greater or lesser than the other.
Subtraction
Before we begin to understand the subtraction of algebraic expressions, we need to list out a few things that form the basis of algebra.
Addition
Before we begin to understand the addition of algebraic expressions, we need to list out a few things that form the basis of algebra.
![A regression analysis was conducted to determine the relationship between hours of TV watched per day (x) and the number of sit-ups a person can do (y).
**The results of the regression were:**
- Equation: \( y = ax + b \)
- Slope (\( a \)): -0.765
- Intercept (\( b \)): 33.696
- Coefficient of determination (\( r^2 \)): 0.3844
- Correlation coefficient (\( r \)): -0.62
**Task:**
Use the regression equation to predict the number of sit-ups a person who watches 8.5 hours of TV can do. Round your answer to one decimal place.
