Ivahew [28]

Answer:

80 ft²

Step-by-step explanation:

A (rectangle) = 2*16 = 32 ft²

Length of pink line is x² = 10² - 8², x =√36 = 6 ft

A(triangle) = (1/2)*base*height = (1/2)*8*6=24 ft²

Area of two triangles = 2*24 = 48 ft²

All area = area of rectangle + area of two triangles = 32 + 48 = 80 ft²

Suppose that p(a) = .25 and p(bc) = .71, and p(a or<br> b.= .38. then the p(a|b) =

hammer [34]

$P(B^C)=0.71\implies P(B)=1-0.71=0.29$

$P(A\cap B)=P(A)+P(B)-P(A\cup B)\implies P(A\cap B)=0.25+0.29-0.38=0.16$

$P(A\mid B)=\dfrac{P(A\cap B)}{P(B)}=\dfrac{0.16}{0.29}\approx0.55$
