But in our case, the probability of backscattering is going to be the number of balls that backscatter, and that's going to be divided by the total number of ping-pong balls.
用20除以132000,但现在背散射,的概率是被散射回来的小球,除以总的小球数,你们记得。
Just take a look: if this is 9, 5 divided by 9 is always going to be 0 point something, and if you thus have two integers and you're rounding down, which is what happens when you do integral math we're using this operator, I'm going to get zero times whatever.
稍微看一看:如果这是9,5除以9会得到,0点几,如果你用两个整型数,你舍去小数,这就是当你们,用整型数使用这个操作的所发生的事情,我将得到数值0乘以任何一个数字。
Their difference divided by the difference in times is going to be the acceleration.
它们的差值再除以时间的差值,就是加速度
If x was even, x divided by two is going to be actually the half of x, right?
如果x是偶数的话,x除以2当然,就等于x的一半了,对不对?
If you had a perpetuity, which paid C/2 forever, you already know from the perpetuity formula that the value of that would be C/2 divided by r/2 if r/2 is the discount rate.
如果你有一只永续债券,每半年付息C/2,没有到期日,从永续债券的公式可以知道,债券价格等于C/2除以r/2,r/2为贴现率
For example, if you started here and you did all this and you came back here, the average velocity would be zero, because you start and end at the same value of x, you get something; 0 divided by time will still be 0.
例如,如果你从这里开始运动,经过这个过程又回到这里,平均速度就是0,因为初态和末态的位移相同,你得到了什么呢,0除以时间还是0
