Answer:
Step-by-step explanation:
<em>Speed = distance/time</em>
- Distance = 20.4 miles
- Time = 17 minutes = 17*1/60 hours = 17/60 hours
<u>Speed is:</u>
- 20.4 : 17/60 =
- 20.4*60/17 =
- 72 mph
<u>Alyn exceeded the limit by:</u>
Answer:
Option C is correct.
Step-by-step explanation:
We have been given total 8 data
Data is : 12,15,18,20,23,23,28
Here, n=7
Median is 
Median is 20.
When one data is added n=8
The median of even number of data is
Median is 
Median is 
4th terms is 20
5th terms is 23
Since, median should not be change hence,
Median will be 20.
Therefore, option C is correct.
Answer:
10/37.
Step-by-step explanation:
The probability that he or she is a management major is 10/37.
The concept of probability that was used was:
Classical probability: The probability is equal to (number of favourable cases) / (number of total cases). Since the total of students who are a management major is 10 and we have 37 students in total, the probability will be 10/37.
Answer: f^{-1}(x) = 3-x/3
Step-by-step explanation: Let y = f(x) and rearrange making x the subject, that is...
1. y = - 3x + 3 ( add 3x to both sides )
2. 3x + y = 3 ( subtract y from both sides )
3. 3x = 3 - y ( divide both sides by 3 )
4. x = 3-y/3
Change x back into terms of y
f^{-1}(x) = 3-x/3
Answer:
Yes, the center of a circle is always and always equidistant from all the points on circumference because that is because what a circle is called. The distance from the center of the circle to the circumference is called the radius and it is constant for any particular circle.
