Let h be the function that assigns each student ID number to a grade level.
denis-greek [22]

Answer:

It is a function Jonny!

Step-by-step explanation:

Hello! I would say to Jonny:

Jonny! A function is a relation between two sets, in which every element of the first set (domain) is assigned only one element of the second set (codomain).

If you have serveral elements of the first set with the same corresponding element of the second set it is correct to call that relation a function.

However, if you have an element of the first set for which your relation can relate to more than one element of the second set, then Jonny, that is not a function.

In the present case, every student ID number can only be realted to a number of the set {9, 10, 11, 12}, a student cannot have more than one current grade level. Therefore, that relation is in fact a function

you need to count from the digit after the decimal point until you reach the 3rd number which is 2

so now the answer is 2470.283

This is because the decimal point lies between 2 and 7 and since 7 is great than 5 we add 1 to the 2 making it 3

aleksandr82 [10.1K]

Answer:

You can do this by rolling dice 4 times

Step-by-step explanation:

If you roll a fair dice 4 times and record the findings and their orders, you can generate 6^4= 1296 possible outcomes. You can pick 1-1000 as numbers and then re-roll all the dice if the number generate 1001-1296  

To translate the dice result into a number you have to multiply the dice result as following:

1st roll multiplied by 6^0 = 1

2nd roll multiplied by 6^1 = 6

3rd roll multiplied by 6^2= 36

4th roll multiplied by 6^3= 216

Let's say you roll 1, 2, 3, 4

The number generated will be: 1*1 + 2 *6 + 3 *36 + 4 *216 = 985
