Answer:
y = tan(x +π/2)
Step-by-step explanation:
It can be helpful to start with a simple sketch of the function you have and of the tangent function. Then, you can see the relationship.
The tangent function is always rising, has vertical asymptotes at -π/2 and π/2, and has a zero crossing at x=0.
The function we want is always rising, has vertical asymptotes at x=0 and x=±π, and a zero crossing at x=-π/2.
We can create the function we want by shifting the tangent function to the left by π/2. The formula that does that is ...
y = tan(x +π/2)
Answer:
The value of the coefficient of determination is 0.263 or 26.3%.
Step-by-step explanation:
<em>R</em>-squared is a statistical quantity that measures, just how near the values are to the fitted regression line. It is also known as the coefficient of determination.
A high R² value or an R² value approaching 1.0 would indicate a high degree of explanatory power.
The R-squared value is usually taken as “the percentage of dissimilarity in one variable explained by the other variable,” or “the percentage of dissimilarity shared between the two variables.”
The R² value is the square of the correlation coefficient.
The correlation coefficient between heights (in inches) and weights (in lb) of 40 randomly selected men is:
<em>r</em> = 0.513.
Compute the value of the coefficient of determination as follows:
Thus, the value of the coefficient of determination is 0.263 or 26.3%.
This implies that the percentage of variation in the variable height explained by the variable weight is 26.3%.
