Well what’s your question you need help with?
Honestly I think that it’s c but check that and get back to me
Answer:
Now we can calculate the absolute deviations from the mean for each value:
|0.4-0.4|=0
|0.2-0.4|=0.2
|0.4-0.4|=0
|0.6-0.4|=0.2
And adding these 4 values and dividing by 4we got the MAD on this case:
Step-by-step explanation:
We have the following dataset given:
0.4,0.2,0.4,0.6
In order to calculate the MAD we need to calculate the sample mean first with this formula:
Replacing we got:

Answer:
20, 40, 60
Step-by-step explanation:
x + 2x + 3x = 120
6x = 120
x = 20
20, 40, 60
30. Sarah = 5+3 = 8W
31. Noah = 8W
32. Yes. Both are equivalent. They both earned the same last week.
8w=8w. (Use any kind of boxed representation to show the equivalents)
