Answer:
1/9
Step-by-step explanation:
You take 1/6 times 4/6 which equals 1/9.
Hope that helped! :)
10 hours.
If you multiply 2 1/2 by 4, the product is 10.
9+4+7+3+10+9=42
42÷6= 34.5. I believe "mean" is the same as avgerage.
Okay so first let’s set one of the two equations equation to one of the two variables
I’m going to pick the second equation and y
So
x+y=10
y=10-x
Now let’s bring the other equation in and substitute y for 10-x
2x+3y=45
2x+3(10-x)=45
Now solve for x
2x+3(10-x)=45
2x+30-3x=45
-x+30=45
-x=15
x=-15
Okay so now we have x = -15 now let’s find y by using the original equation I moved around and pigging in y like
y=10-x
Plug in x
y=10-(-15)
y=10+15
y=25
So now that I look back at the program you only needed x but her is x and y I hope I helped
Answer: See the diagram below
==========================================================
Explanation:
She starts off finding the mean of the data. So she adds up the values to get 48+54+57+62+69 = 290, and then divides by 5 to get the mean of 290/5 = 58. That explains why there's a 58 in the first row of the second column.
---------------------
For the next step, she subtracts 58 from each data item. If the result is negative, then go with the positive version (ie apply the absolute value)
- |48-58| = 10
- |54-58| = 4
- |57-58| = 1
- |62-58| = 4
- |69-58| = 11
This leads to the list 10,4,1,4,11 which goes in the first slot labeled "drag and drop an item here". This is the list of distance values each item is from the mean.
---------------------
The last thing to do is find the mean of the set {10,4,1,4,11}
add: 10+4+1+4+11 = 30
divide by five: 30/5 = 6
The mean absolute deviation (MAD) is 6
This represents the average distance each data value is from the mean. The MAD tells us how spread out the data is. It's similar to the standard deviation.
