Answer:
10/r x 4
Step-by-step explanation:
Answer with explanation:
There are few number of white ball in 10 boxes.
Total number of Black balls in the box=60
So, we have to write number 60 in such a way that, such that it can be represented as sum of ten different digits.
That is the only way by which we can distinguish between ten boxes.
60 =0 +1+2+3+4+6+8+10+12+14
Place these balls in ten different boxes.
So, by this way we can distinguish between boxes.

Given that S<span>am's distribution of meal costs has a mean of $9 and a standard deviation of $3, this means that the range of Sam's meal cost that are within one standard deviation is given by ($9 - 3, $9 + 3) = ($6, $12).
Given that Sam </span><span>always tips the server $2 plus 10% of the cost of the meal, this means that when the cost of the meal is $9, Sam tips $2 + (0.1 x 9) = $2 + $0.9 = $2.90
Therefore, the mean of the distribution of Sam's tips is $2.90
Similarly, the </span><span>range of Sam's tips that are within one standard deviation is given by ($2 + 0.1(6), $2 + 0.1(12)) = ($2 + 0.6, $2 + 1.2) = ($2.6, 3.2) = ($2.9 - $0.3, $2.9 + $0.3)
Therefore, </span><span>the standard deviation of the distribution of Sam's tips is $0.3</span>
