The regression line for predicting muscle mass percentage using biceps circumference is MuscleM ass \( =5.1+2.02 \) (Biceps) One man in the study has a biceps circumference of 21 in . and a muscle mass percentage of \( 48.4 \% \). Find the residual for this ma The residual for this man is \( -0.9 \% \). The residual for this man is \( 0.9 \% \) The residual for this man is \( -2.02 \% \). The residual for this man is \( 2.02 \% \).

Find the derivative of \( y \) with respect to \( x \) \[ \begin{array}{l}y=2 x^{4} \sin ^{-1}\left(2 x^{4}\right)+\sqrt{1-4 x^{8}} \\ \frac{d y}{d x}=\square\end{array} \]

Temperature Change In the United States, temperature is measured on the Fahrenheit temperature scale. On this scale, water boils at 212 degrees and freezes at 32 degrees. To denote a temperature of 32 degrees on the Fahrenheit scale, we write: \[ 32^{\circ} \mathrm{F} \text {, which is read " } 32 \text { degrees Fahrenheit" } \] At 10:00 in the morning in White Bear Lake, Minnesota, John notices the temperature outside is 15 degrees below zero Fahrenheit. A.) Write the temperature as a negative number Ans: Fahrenheit. B.) An hour later it has warmed up by 3 degrees. What is the temperature at 11:00 that morning? Ans: degrees Fahrenheit.

Simplify the square root. \( \sqrt{28} \)
