A)The outlier if the data is 28 because it is 30+ numbers away from the next number. B) The mean for this data is 67.45. C) it would be 71.4 without the outlier. P.S to find the mean you add all the numbers together and then divide it by however many numbers there are. Hope this helps
Hello!
First you find how far he went
So he we 96 kilometers there and back
96 + 96 = 192
It took him 8 hours to go 192 kilometers
To find the average speed you divide these two
192/8 = 24
So his average speed was 24 kilometers an hour
The answer is 24
Hope this helps!
2(a+3)+3(2a-1)
=2a+6+6a-3
=8a+3
$36
I think
$0.89 rounds up to $1.00
$0.75 rounds up to $1.00
$1.60 rounds up to $2.00
then multiply each by 9 for the 9 children
9
9
18
then add together
9+9+18=36
You have to turn the whol number back into an improper fraction, then you do what you would regulary do with the division of fractions.
