The formula linking pressure \( \left(P \mathrm{~N} / \mathrm{m}^{2}\right) \), force \( (F \mathrm{~N}) \) and surface area \( \left(A \mathrm{~m}^{2}\right) \) is given as \( P=\frac{F}{A} \). A square-based box exerts a force of 160 N on a floor. If the pressure on the floor is \( 1000 \mathrm{~N} / \mathrm{m}^{2} \), calculate the length, in cm, of each side of the base of the box.

Why did we need to plot the 26 hemoglobin levels? To find the sample mean, \( \bar{x} \). To make sure there are no outliers indicating non-Normality. To estimate the variability in the sample of hemoglobin levels.

A species of mouse and a species of lizard both independently evolve darker coloration on a large lava flow. This would be considered an example of: polyploidy convergent evolution sexual selection genetic drift

1. Find "a" such that \( f(x) \) is continuous on its entire domain. \( f(x)=\left\{\begin{array}{ll}\frac{4 \sin (x)}{x} & , x<0 \\ a-2 x & , x \geq 0\end{array}\right. \)
