Help I’m stuck on this question: Jordan and Matt are camping. They decide to hike 4.6 miles away from camp and then turn north
mike 1.8 more miles. Which of the following is a possible distance of how far they are from camp?
A
1.5 miles
B
2.8 miles
I
C
5.3 miles
D
6.4 mile

C

Step-by-step explanation:

Let d = the distance from camp

d < 1.8 + 2.6 = 6.4    

d > 2.8

so 2.8 < d < 6.4,  therefore d could be 5.3

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean =

also, median= , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =  

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.
