Step-by-step explanation:
Answer:
55 miles per hour
Step-by-step explanation:
given the originally traveled 40 miles in one hour gives us 40 mph, 180 miles in the last 3 hours gives us an average of 60 mph for the second part, 40+60+60+60 (for the 3 hours going that fast) is equal to 220, divide that by 4 to give us our average of 55 mph
ok for number 2.) 2+8+1+5+1+3+1+7+5+4+3+1=41 and 41 divided by the number of number which is 12= 3.41666666667
the mean for number 2 is 3.41666666667.
for the median you put the number from least to greatest, like so:
1, 1, 1, 1, 2, 3, 3, 4, 5, 5, 7, 8.
The middle is 3 and 3 so 3+3 divided by 2 is 6 so the median is 6.
I cant do mode but range is 8-1 divided by 2
Perimeter is just the addition of the side lengths so add them together:
5c+6 + 2c+5 = 7c+11
Option D.
