Answer:</h2>
Prediction for the number of unsuccessful rolls is 15.
<h2>
Step-by-step explanation:</h2>
There is 
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 
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.

Answer:
Answer is A. 30 degree
as we know that two prependicular lines have 90 degree angle between them
and similarly a horizontal line has angle zero degree.
the angle of pic shown is approximately 30 degree as it lies between prependicular and horizontal nature of lines
but as we can see that it is close to horizontal nature of the line that's why its approximate angle is 30 degree.
100% - 7% - 30% = 63% of people are on the sand
Answer:
The mean of X is 122.5 and the standard deviation is 7.9.
Step-by-step explanation:
For each adult, there are only two possible outcomes. Either they believe that the overall state of moral values is poor, or they do not believe this. The probability of an adult believing this is independent of other adults. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
Probability of exactly x sucesses on n repeated trials, with p probability.
The expected value of the binomial distribution is:
The standard deviation of the binomial distribution is:
In this problem, we have that:
So
The mean of X is 122.5 and the standard deviation is 7.9.
