Answer:
the mean is 8 and the absolute deviation is 1.5
Step-by-step explanation:
to find the mean you add up all the numbers, then you just divide by how many numbers there are. in this case, you would do 64/8 which would then equal 8. then you see how much the numbers differ from the mean. like for your numbers, for 8 it would be 0, for 9 it would be 1, for 7 it would be 1, for 6 it would be 2. you see it? its just how far away it is from the mean. so once you do that, you should have a 6. then you do 6/4 which is 1.5. hope this helps!
60% of the total (30) can swim
60% of 30 = (60/100)*30 = 0.60*30 = 18
So 18 children can swim
This means 30-18 = 12 cannot swim
---------------------------------------------------------
An alternative is to do it this way:
We know 60% can swim so that means 40% cannot swim.
Notice how 100% - 60% = 40%
Or in other words, the 60% and 40% add to 100%. This is because we have two choices: either the person can swim or cannot swim
Since 40% cannot swim, this means
40% of 30 = (40/100)*30 = 0.40*30 = 12
and we get the same result as before
---------------------------------------------------------
Final Answer: 12
Answer:
Hans:6
Eric:18
Kaitlin:74
Step-by-step explanation:
first create an equation using the information in the question
5h+68=98
first subtract 68
5h+68=98
-68 -68
5h=30
divide by 5
Hans:6
multiply by 3
Eric:18
68+6=74
Kaitlin:74

D. No x value has more than one y value so it's a function.
Since 540 is a whole number, it cannot be simplified anymore.
