Billy the friendly Robot uses 50 N of force to lift a box 2 meters in the air. How much work did Billy perform?

padilas [110]

Answer:

0.04

Step-by-step explanation:

you want to leave "N" by itself on one side of the equal sign so divide 50N by 50 and your are left with "N". You also have to divide 50 by 2 on the other side of the equal sign. now you have N=2÷50.

2÷50= 0.04!

If x is uniformly distributed over the interval 8 to 12, inclusively (8 x 12), then the probability, p(13 x 15), is ____________

kap26 [50]

$f_X(x)=\begin{cases}\dfrac1{12-8}=\dfrac14&\text{for }8\le x\le12\\\\0&\text{elsewhere}\end{cases}$

This means $\mathbb P(13\le x\le15)=0$ since this interval lies outside the support of the density function.
