In a game the player wins if he rolls a 6 on a number cube .if the number cube is rolled 18 times then what is the reasonable

sp2606 [1]

<h2>Answer:</h2>

Prediction for the number of unsuccessful rolls is 15.

<h2>Step-by-step explanation:</h2>

There is $\frac{1}{6}$ chance of rolling number 6 on the cube. If we want to find out what is the prediction for rolling number 6 in 18 rolls, we need to multiply $6*\frac{1}{6}$ which is 3. So if we roll a cube 18 times, we will probably got number 6 three times. When we subtract 3 from 18 (18-3), we get 15. That is the answer to your question.

5 ( n - 7 ) = 2 ( n + 14 )

wariber [46]

Answer:

n=21

Step-by-step explanation:

We must find n.

Remember PEMDAS. First we must do the Parentheses. Lets do distributive property by multiplying a number that is immediately outside the parentheses with each number inside the parentheses. Lets do this one side at a time.

First lets do 5(n - 7). We get 5n - 35

Now 2(n + 14) is 2n + 28

Okay...... now we have $5n-35=2n+28$
