Step-by-step explanation:
First arrange the data in an order
3, 3, 3, 7, 7, 10, 10, 12, 12, 13, 14, 17, 17, 18, 21
a.) Q1 = (N + 1)/4th item = (15 + 1)/4 = 4th item = 7
Q2 = 2(16)/4 = 16/2 = 8th item = 12
Q3 = 3(16)/4 = 3(4) = 12th item = 17
IQR = (Q3 - Q1)/2 = (17 - 7)/2 = 10/2 = 5
b.) 82nd percentile = 82(16)/100 = 13th item = 17
c.) 12 is the 8th item which is in the middle of the data set, so the percentile rank is 50%
Answer:$104.5
Step-by-step explanation:
cats=c
Dogs=d
2c+3d=455
d=82
Substitute d=82 in 2c+3d=455
2c+3(82)=455
2c+246=455
Collect like terms
2c=455-246
2c=209
Divide both sides by 2
2c/2=209/2
c=104.5
1 cat cost $104.5
