The area of the shaded region is $0.215a^2$

<h2>Area of composite objects</h2>

The area of the shaded region is expressed according to the formula:

$A = A_s - A_c$

Get the area of the square As

As = a²

$A_c = \pi (0.5a)^2\\
A_c = 0.785a^2$

Take the difference in the areas

Area of the shaded part = $a^2-0.785a^2\\
$

Area of the shaded part = $0.215a^2$

Hence the area of the shaded region is $0.215a^2$

You have 200 dice in a bag. One of the dice has a six on all sides so it will land on a six every time you roll it. The other 19

LiRa [457]

Answer:

Step-by-step explanation:

There are 200 dice out of which 199 are fair

Prob for 6 in one special die = 1 and

Prob for 6 in other die = 1/6

A1- drawing special die and A2 = drawing any other die

A1 and A2 are mutually exclusive and exhaustive

P(A1) = 1/200 and P(A2) = 199/200

B = getting 6

i) Required probability

= P(A1/B) = $\frac{P(A1B)}{P(A1B)+P(A2B)} \\$

P(A1B) = $\frac{1}{200} *1 = \frac{1}{200}$

P(A2B) = $\frac{199}{200}*\frac{1}{6}=\frac{199}{1200}$

P(B) = $\frac{205}{1200} =\frac{41}{240}$

P(A1/B) = $\frac{1/200}{41/240} =\frac{7}{205}$

P(A2/B) = $\frac{199/1200}{41/240} =\frac{199}{205}$

Same solution as 2(x+4=-7-3x

Bas_tet [7]

Answer:

x = -3

Step-by-step explanation:

2(x+4)=-7-3x

Distribute

2x+8 = -7-3x

Add 3x to each side

2x+3x+8=-7-3x+3x

5x +8 = -7

Subtract 8 from each side

5x+8-8 = -7-8

5x = -15

Divide each side by 5

5x/5 = -15/5

x = -3
