Answer:
2 → 3 → 1 → 4
Step-by-step explanation:
We are given the list of cost of fabric in dollars per square yard.
So, the total cost per square yard of different fabric are:
1. 6.5 for $6.25 = 
= 0.96
2. 4 for $3 = 
= 0.75
3. 8.5 for $8.10 = 
= 0.95
4. 6 for $7.20 = 
= 1.2
Since, 0.75 < 0.95 < 0.96 < 1.2
Hence, from least to the greatest unit cost, the sequence is 2 → 3 → 1 → 4.
This is work in the 5th grade and it is 3400 to be exact!!!!!
As IQ scores for extensive populaces are focused at 100, the mean = 100.
There ought to be around half scores above or underneath the mean score since mean and middle is about a similar when the populace is substantial.
P(x > 100) = P( z> (100 - 100)/sd ) = P(z > 0)= 0.5
The number of the student who has scored over 100 = 0.5 x 78 = 39 Therefore the answer is 39 students.
You can find how many he gets for each dog.
For example, let's pretend Juan gets $3 for each dog to walk, then he would've walked 4 dogs. But in this real problem we don't know how much he gets for each dog.
So, you can find the amount of money Juan saved by knowing how much is for each dog walked.
