2 opposite interior angle (opposite to the exterior angle) added together are equal to the exterior angle
6x-1+85 = 18x
6x +84 = 18x
subtract 6x from both sides
84 = 12x
divide both sides by 12
x = 7

It is 0.35 That is the answer.
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:
2A/h - b<em>2</em>= b<em>1</em>
Step-by-step explanation:
A = 1/2 ( b<em>1</em>+ b<em>2</em>) h
Multiply each side by 2
2*A = 2*1/2 ( b<em>1</em>+ b<em>2</em>) h
2A = ( b<em>1</em>+ b<em>2</em>) h
Divide each side by h
2A/h = ( b<em>1</em>+ b<em>2</em>) h/h
2A/h = ( b<em>1</em>+ b<em>2</em>)
Subtract b<em>2 </em>from each side
2A/h - b<em>2</em>= b<em>1</em>+ b<em>2-</em>b<em>2</em>
2A/h - b<em>2</em>= b<em>1</em>
