Answer:
$8.80
Step-by-step explanation:
In order to find the new price, you need to add 60% of the original price (5.50) to the original price. You have two options:
1) multiply $5.50*0.6 to get 60% of the original price. You would get $3.30. Then add $3.30+$5.50, which equals $8.80. This way takes longer but shows you all the steps.
2) The shorter way is to simply multiply $5.50*1.6, which also equals $8.80. This works because the "1" automatically adds the 5.50 to 60% of the original price, this way you don't have to multiply then add.
If you don't understand how the second way works or your teacher taught you #1, just do it the first way.

Answer:
0.7941 miles
Step-by-step explanation:
I would think of this situation as a giant ruler.
The 18 trash cans can be thought of as endpoints on intervals in this giant ruler.
1--------2 --------3 --------4-----------5
If you notice the numbers that I wrote, there are five of them, but there are 4 intervals.
So we need to minus one from 18 to get 17 equal length intervals so that the trash cans are equally spaced.
Interval length = 13.5 miles / 17 intervals = 0.7941 miles
Answer:
Z score associated with sleeping 503 minutes = 0 minutes
Step-by-step explanation:
Given values of sleep per night for adults:
Mean value X = 503
Standard deviation σ = s
FInd:
Z score associated with sleeping 503 minutes
Computation:
⇒ P[X = 503]
⇒ P[(x - X) / σ] = [503 - 503] / s
⇒ Z score value = [0] / s
⇒ Z score value = 0
Z score associated with sleeping 503 minutes = 0 minutes
