Answer:
= 60 miles / hour
Step-by-step explanation:
We first convert the time of 4 hours 41 minutes in minutes
4 hours 41 minutes = 4 × 60 + 41 = 281 minutes
Average speed S is given by distance / time. Hence
S = 281 miles / 281 minutes = 1 mile / minute
= 60 miles / hour
Answer:
D
Step-by-step explanation:
you distribute 5.6 to the values inside of the perenthesis. 5.6 x 3.17x is 17.725x. don't forget about the x!
Mean = Numbers added up and divided by the amount of numbers.
Mean = 45 + 90 + 18 + 53 + 13 + 38 + 22 + 59 + 49
Mean = 387 ÷ 9
Mean = 43
Median = The middle number when arranged in order
Median = 13, 18, 22, 38, 45, 49, 53, 59, 90
Median = 45
Mode = The number that occurs most often
Mode = There is no mode because each number occurs the same amount of times
Range = Biggest number takeaway smallest number
Range = 90 - 13
Range = 77
