Respuesta: P\izquierda(x\ge4\derecha)=0.7 Solución paso-a-paso: P\left(x\ge4\right)=P\left(x=1\right)+P\left(x=2\right)+P\left(x=3\right)+P\left( x=4\derecha)=0,05+0,2+0,25+0,2=0,7

User One of the applications of the derivative of a function is its use in Physics, where a function that at every instant t associates the number s(t), this function s is called the clockwise function of the movement. By deriving the time function we obtain the velocity function at time t, denoted by v(t). A body has a time function that determines its position in meters at time t as S(t)=t.³√t+2.t . Present the speed of this body at time t = 8 s.
