Answer:
Step-by-step explanation:
Given that,pros.
lpsa = 1.507 + 0.719 lcavol
lpsa=0.719 lcavol + 1.507
Comparing this to equation of a straight line, y=mx+c
Then,
slope (m) = 0.719
And intercept (c) on y axis is 1.507
Then, the x axis is lcavol
Also, the y axis is lpsa.
Then the linear model preview is

Answer:
4
Step-by-step explanation:
A = first piece, b = second piece, c = third piece
a + b + c = 47
b = 3a
c = 5a + 2
a + (3a) + (5a + 2) = 47.....combine like terms
9a + 2 = 47
9a = 47 - 2
9a = 45
a = 45/9
a = 5 ft
b = 3a.....b = 3(5)....b = 15 ft
c = 5a + 2....c = 5(5) + 2.....c = 25 + 2....c = 27 ft
longest piece (c) = 27 ft
