Given circle O, angle A has a measure of 36° and the radius is 10 cm, find the area of sector BOC.

Fed [463]

Answer:

The area of the sector BOC is A' = 31.4 $cm^{2}$

Step-by-step explanation:

Radius of the circle = 10 cm = 0.1 m

Angle of sector $\theta$ = 36°

Area of the circle A = $\pi r^{2}$

A = 3.14 × $0.1^{2}$ = 0.0314 $m^{2}$

Now area of the sector BOC is

$A' = A (\frac{\theta}{360} )$

$A' = 0.0314 (\frac{36}{360} )$

A' = 0.00314 $m^{2}$ = 31.4 $cm^{2}$

Therefore the area of the sector BOC is A' = 31.4 $cm^{2}$

The probability that Chloe acts hungry at 7pm given that she has already eaten dinner is 0.5. The probability that Chloe acts hu

kolezko [41]

Answer:

a) P( $Y^{C}$ | X ) = 0.180

b) P(Y | $X^{C}$ ) = 0.998

Step-by-step explanation:

Let

P(X) - Probability that he acts hungry

P(Y) - Probability that he had ate dinner,

Given,

P(X | Y) = 0.5

P(X | $Y^{C}$ ) = 0.99

P(Y) = 0.9

a.)

P( $Y^{C}$ | X ) = $\frac{P( X | Y^{C} ). P(Y^{C} ) }{P( X | Y^{C} ). P(Y^{C} ) + P( X | Y ) . P (Y) }$

= $\frac{(0.99)(0.1)}{(0.99)(0.1) + (0.5)(0.9)} = \frac{0.099}{0.549}$ = 0.180

⇒P( $Y^{C}$ | X ) = 0.180

b.)

P(Y | $X^{C}$ ) = $\frac{(1 - P(X | Y ) ) . P(Y)}{P( X^{C} ) } = \frac{(1 - P(X | Y ) ) . P(Y)}{ 1 - P( X ) }$

= $\frac{(1 - 0.5)(0.9)}{1 - [(0.99)(0.1) + (0.5)(0.9) ]} = \frac{(0.5)(0.9)}{1 - [(0.099) + (0.45) ]} = \frac{0.45}{1 - [0.540]} = \frac{0.45}{0.451}$ = 0.998

⇒P(Y | $X^{C}$ ) = 0.998

Answer:

48 tapes

Step-by-step explanation:

2/3 is given away

24 x 3 = 72

2/3 of 72 = 24 x 2

24 x 2 = 48
