The average mileage covered per day is =(x+y+z)/3
The first answer should be correct
Answer: 8
Step-by-step explanation:
<span>The total number of students in the class is 9 + 7 = 16
The probability first person is a girl is 9/16
The probability second person is a girl is 8/15
The probability third person is a girl is 7/14
The probability that three girls are the first to enter is 9/16 * 8/15 * 7/14 = 504/3360 = 0.15. Option A.</span>
Well, you take 0.199 find the hundredths place, which is the 9 to the left in this example, and decide whether the number to the right of the nine is more than 5, which it is, so we round the 9 up. However, we can't just make it 10 hundredths, so we have to simplify it to 1 tenth and add it onto the tenths place to make 0.20.
