Answer:
<u>18</u> passengers the roller coaster can take around the track per minute.
Step-by-step explanation:
Given:
A roller coaster can take 162 passengers around the track in nine minutes. The roller coaster operates at a constant rate.
Now, to find the number of passengers roller coaster take around the track per minute.
As given in 9 minutes the roller coaster track 162 passengers.
So, we solve by using unitary method:
In 9 minutes the roller coaster take passengers = 162.
Thus, in 1 minute it can take
Therefore, 18 passengers the roller coaster can take around the track per minute.

Answer: $20
Step-by-step explanation:
Let 'x' be the cost of a ticket at Haynes
Let 'y' be the cost of a ticket at Valley
Since the total cost from both schools are the same, we can write it as:
Since the cost of tickets at Valley was $5 less than Haynes, we can write it as:
Now we have two equations, we can use to substitute into the other expression:
we substitute y in this equation with the other equation
Therefore the cost of the ticket at Haynes is $20 and the cost of the ticket at Valley is $15.
Answer:
Mean = 15.83 hours
Median = 17 hours
Step-by-step explanation:
The first step to follow when dealing with data distributions is to arrange the data in either an ascending or descending order.
Once this is done, we have the responses as
responses: 9. 14, 16, 18, 19, 19
The mean of the distribution can be obtained by dividing the total sum of the values, by the number of respondents.
this is
The mean of the distribution is 15.83 hours
The median is obtained by picking out the middle number of the distribution. However, our distribution is even, and hence has two middle numbers. To solve this , we simply add the two numbers and divide by 2
= (16 + 18 )/2 = 34/2 = 17
