The lower quartile is the median of the lower part of the data.
P(x) = 3x + 200
x=4 ⇒ p(4) = 3(4)+200=12+200=212
x=15 ⇒ p(15) = 3(15)+20=45+200=245
n(x) = 200(1.04)^x
x=4 ⇒ n(4) = 200 (1.04)^4 = 233.97
x=15⇒n(15)=200(1.04)^15 = 360.19
Then n(x) has the highest value in 4 years; n(x) has the highest value in 15 years
Answer:
Delta = |a b d; b c f; d f g|
(2)
J = |a b; b c|
(3)
I = a+c
(4)
K = |a d; d g|+|c f; f g|.
