Notice it is +/-4 times standard deviation (0.65-0.04 = 0.61, 0.69-0.04=0.65)
That's almost everything. So (D) is the answer.

The answer to this is 19. The reason why is because the median falls between 18 and 20. After that, you have to take the middle number that falls between 18 and 20. In this case, 19.
Step-by-step explanation:
4 9/10 + 3 7/10
49/10 + 37/10(turned into an improper fraction
86/10 ( both figures added )
=8 6/10(result)
The answer needs to be in mph, or "miles per hour", so let's convert "5 hours and 15 minutes" to pure hours (with no minutes attached)
Since there are 60 minutes in an hour, this means that 15 minutes = 15/60 = 1/4 of an hour (quarter of an hour). I'm going to convert the fraction 1/4 into decimal form 0.25; use a calculator or long division to compute this.
Therefore,
5 hours and 15 minutes = (5 hours) + (15 minutes)
5 hours and 15 minutes = (5 hours) + (0.25 hours)
5 hours and 15 minutes = (5+0.25) hours
5 hours and 15 minutes = 5.25 hours
---------------------------------------------------------
The car travels 183.75 miles (given) for 5.25 hours (value computed above). Use the formula shown below to find the speed or rate
speed = distance/time
s = d/t
s = 183.75/5.25
s = 35
Note: your math book might use "r" instead of "s".
So the speed of the car is 35 miles per hour
