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:
for rewrite in vertex form is -16(t-19/16)^2 + 441/16
for rewrite in intercept form is h= -16(t-5/2)(t+1/8)
