Answer:
Landers' Mean: 136
Landers' Median: 133
Shakaka's Mean: 136
Shakaka's Median: 133
Step-by-step explanation:
Landers:
Least to greatest: 96, 96, 120, 133, 145, 160, 202
Mean: (96+ 96+ 120+ 133+145+ 160+202)/7 = 136
Median: Since the total numbers is odd, it's just flat out in the middle
133
Shakaka:
Least to greatest: 45, 51, 118, 121, 145, 178, 212, 218
Mean: (45+ 51+ 118+ 121+ 145+ 178+ 212+ 218)/8 = 136
Median:
(121 + 145)/2 = 133
Let the relative speed will be given by:
38/4=9.5 km/h
Let the speed of the first tourist be x km/h
the speed of the second one is (9.5-x) km/h
distance covered by the first one is:
4*x+2=4x+2 km
distance covered by the second one is:
(9.5-x)4 km
=(38+4x) km
total distance will be given by:
(38+4x)+(4x+2)=38
40+8x=38
8x=-2
x=-1/4 km/h
this mean that he was traveling in the opposite direct thus the speed was 1/4 km/k
The speed of the second one will be:
9.5-1/4=9.25 km/h
2.5x + 4y < = 60
its just a matter of subbing in ur answer choices and see which one does not work.
2.5(18) + 4(6) < = 60
45 + 24 < = 60
69 < = 60...incorrect
so the one that does not work is : 18 bags of chips and 6 jars of salsa
3 cars earns him $600.
(0.03)*$32,343 = $907.29 commission
total earnings = $907.29 + $600
= $1,507.29
