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
Third option.
Use y = mx + b (slope-intercept form) to get
y = (1/3)x + b.
Then plug in the point (1,-2) for x and y to figure out b...
-2 = (1/3)(1) + b
-2 - 1/3 = b, so b = -7/3
Now you have y = (1/3)x - 7/3. Convert to standard form by multiplying each term by 3 to get
3y = x - 7. Then move the 3y to the other side to get 0 = x - 3y - 7
Your brother is correct, because the sequence is increasing.
Answer:
30% discount and another 30%
but this is not the only possible answer, to see other answers, make sure both percentage adds up to 60%
