Answer:
Justin has a lower mean tip for the week with $42.
Step-by-step explanation:
To find the mean you must add all the numbers and then divide the sum by how many numbers there are.
For Justin you must add 32 + 45 + 50 + 33 + 50 then you'll get the sum 210. There are 5 numbers so you divide 210 by 5 which gives you the quotient 42.
As for T.J. you add 58 + 48 + 40 + 42 + 42 which gives you the sum of 230. Then you divide 230 by 5 since there's 5 numbers. Now you have the quotient of 46.
46 is greater than 42 so Justin has the lower mean.
The answer is the second one I dont have that symbol on my keyboard but it’s the second answer on the multi choice
90-11.65-56=22.35
divide that by 3.72 u get 6 so she can only get six comics or any whole positive number lower than that. Therefore it’s #2
Answer:
Step-by-step explanation:(2ñ-4)90
(7×2-4)90
=900°
900-(162+125+148+105+98+115)
900-753
=147°
Answer
Notebook each =$4
Folder each = $9
First we write out what we know
Notebook = n
Folder = f
It says a notebook is +5 than a folder so
f = n +5
It says he bought 3 notebooks and 2 folders for $30
3n + 2f = 30
Because we know from the first equation
f=n+5, we can substitute that into the second equation for f
3n + 2(n+5) = 30
3n + 2n +10 =30. Now Combine like terms
5n +10 =30. Now isolate n by subtracting 10 from both sides
5n = 20. Now isolate n by dividing both sides by 5
n = 4
Now we do the same thing to find f
We substitute the value of n (4) into the equation 3n + 2f =30
3(4) +2f =30
12 +2f =30. Now isolate f by subtracting 12 from both sides
2f = 18. Now isolate f by dividing both sides by 2
f = 9
We check our work by inserting the n and f values we found into one of the equations
n + 5 = f
4 + 5 = 9
9 = 9. It worked it equals so it’s correct
