Did you try the answer b?
Answer:
A) 0.2
Step-by-step explanation:
From least to greatest, the data points are
6, 6, 6, 7, 7, 7, 8, 8, 8, 9
To find the mean, we find the sum of the data points and divide by the number of data points, 10. The sum of the data points is
6+6+6+7+7+7+8+8+8+9 = 72
Dividing by 10, the mean is 72/10 = 7.2.
The median is the middle number in the set. This is 7.
The difference between the mean and the median is
7.2-7 = 0.2.
Answer:
2?
Step-by-step explanation:
This was a difficult one, I hope it's right, Goodluck
80*90% = 80*0.9 so 80*0.9=72
First, we need to find out what -3 + 7 is. -3 + 7 = 4. The reason that we got 4 is because we started at -3 and went forward 7 times. When we went forward 7 times, we landed on 4. Next, we need to find out out what -10 - 2 is. -10 - 2 is -12. The reason we got -12 is simple. There is a little method that I like to call keep,change, opposite. First, we keep -10 as is. Next, we switch - to a + sign. Finally, what is the opposite of 2. You guessed it, it's -2. When you put all the pieces together, it is -10 + (-2)= -12. But we are not done yet, four is greater than -12 because -12 is a negative number while 4 is a positive. So, the answer would be "C"
Hope this helped
