If \( n p \geq 5 \) and \( n q \geq 5 \), estimate \( P( \) fewer than 5 ) with \( n=14 \) and \( p=0.5 \) by using the normal distribution as an approximation to the binomial distribution; if \( n p<5 \) or \( n q<5 \), then state that the normal approximation is not suitable. Select the correct choice below and, if necessary, fill in the answer box to complete your choice. A. \( P( \) fewer than 5\( )=\square \) (Round to four decimal places as needed.) B. The normal approximation is not suitable.

A ball is thrown straight upward. The function \( f(t)=-16 t^{2}+64 t \) describes the ball's height above the ground, \( f(t) \), in feet, \( t \) seconds after it is thrown, Complete parts a through \( c \). Interpret \( f(1) \). The ball is 48 feet above the ground alter 1 seconds. \( f(4)=\square \)

50. \( z=6-2 x-3 y, \quad c=0,2,4,6,8,10 \)
