You get 12.6
After the decimal starts the the tenth place. In order to round to the tenth place, we need to know the hundredth place which is the 7. If the hundredth place is 5 or greater then we round up and if it's 4 or lower then we keep the tenth place the same number as it is before.
Since the hundredth place is greater than or equal to 5, we round up the tenth place to 6. If you have any questions then leave a comment. Good luck!
Answer:
The probability that the average score of a group of n = 4 people is between 70 and 75=0.13591
Step-by-step explanation:
We are given that


n=4
We have to find the probability that the average score of a group of n = 4 people is between 70 and 75.






Hence, the probability that the average score of a group of n = 4 people is between 70 and 75=0.13591
Ummm if the numbers are 800 and 12% the answer is 96 students
12/100=x/800
100x=9600
x=96
