Answer:
slope= 0.52
Step-by-step explanation:
For American women
Mean (x) = 64 inches
Standard deviation (sx) = 2.7 inches
For American Men
Mean(ÿ) = 69.3 inches
Standard deviation (sy) = 2.8 inches
r = 0.5
Slope = ??
Husband height = Y
Wife height = X
the general equation of regression line
y = a + bx
The slope of the regression line is the linear correlation coefficient multiplied by the standard deviation for Y
b = r (sy/sx)
b = 0.5(2.8/2.7)
b = 0.52
The intercept a = ÿ - bx
a = 69.3 - 0.52(64)
a = 69.3 - 33.28
a = 36.02
The equation of the regression line y = a + bx
y = 36.02 + 0.52x
Answer:
It's 144 square units
Step-by-step explanation:
The pyramid has a square base with 8 sides and a slant height of 5
a=8
l=5
The total are of the square base pyramid is
A= +2al
a is side length of square and l is slant height
A= x 8 x 5
A=64+80
A=144
Answer:
x=7
Step-by-step explanation:
Add 2/3 to both sides
12x=84
Divide both sides by 12
x=7
