If 8 identical blackboards are to be divided among 4 schools,how many divisions are possible? How many, if each school mustrecei
MAXImum [283]

Answer:

There are 165 ways to distribute the blackboards between the schools. If at least 1 blackboard goes to each school, then we only have 35 ways.

Step-by-step explanation:

Essentially, this is a problem of balls and sticks. The 8 identical blackboards can be represented as 8 balls, and you assign them to each school by using 3 sticks. Basically each school receives an amount of blackboards equivalent to the amount of balls between 2 sticks: The first school gets all the balls before the first stick, the second school gets all the balls between stick 1 and stick 2, the third school gets the balls between sticks 2 and 3 and the last school gets all remaining balls.

 The problem reduces to take 11 consecutive spots which we will use to localize the balls and the sticks and select 3 places to put the sticks. The amount of ways to do this is {11 \choose 3} = 165 . As a result, we have 165 ways to distribute the blackboards.

If each school needs at least 1 blackboard you can give 1 blackbooard to each of them first and distribute the remaining 4 the same way we did before. This time there will be 4 balls and 3 sticks, so we have to put 3 sticks in 7 spaces (if a school takes what it is between 2 sticks that doesnt have balls between, then that school only gets the first blackboard we assigned to it previously). The amount of ways to localize the sticks is {7 \choose 3} = 35. Thus, there are only 35 ways to distribute the blackboards in this case.

I need help I’ll mark u as brainlest
son4ous [18]

Answer:

V = 6 in ^3

Step-by-step explanation:

The formula for volume is

V = Bh where B is the area of the base

The base is a triangle and the height is 2 inches

B = 1/2 bh where b is 3 and h is 2

B =1/2 (3)*2 = 3 in^2

V = 3 *2

V = 6 in ^3

Type a digit that makes this statement true.<br><br> 5,072,<br> 00 is divisible by 8.
lina2011 [118]

The divisibility rule for 8 is that the last three digits have to be divisible by 8.

The third digit of 5072_00(from the right) could be 2, 4, 6, 8, or 0, because 200, 400, 600, 800, and 0 are divisible by 8.

Pls give brainliest.
