Answer:

of the 4 people that have a sister, 2 of them have a brother

Step-by-step explanation:

probability of B given A

given that the person has a sister, what is the probability they have a brother

P (B/A) = 1/2

with this venn diagram

Find the second derivative at the point (2,2), given the function below. 2x^4=4y^3

Bogdan [553]

The second derivative at the point (2,2) is 34/9

Explanation:

2x⁴ = 4y³

2x⁴ - 4y³ = 0

We first need to find dy/dx and then d²y/dx²

On differentiating the equation in terms of x

dy/dx = d(2x⁴ - 4y³) / dx

We get,

dy/dx = 2x³/3y²

On differentiating dy/dx we get,

d²y/dx² = 2x²/y² + 8x⁶/9y⁵

$\frac{d^2y}{dx^2} = \frac{2 X 2^2}{2^2} + \frac{8 X 2^6}{9 X 2^5}\\ \\\frac{d^2y}{dx^2} = 2 + \frac{16}{9}\\ \\$

d²y/dx² = 34/9

Therefore, the second derivative at the point (2,2) is 34/9

Area of a circle = πr^2

Area of a sector with angle x° = (x/360) πr^2

For the smaller sector,

x = 30°

r = 6 in

Required area of sector = (30/360) × π × 6^2 = 9.424 in^2

To the nearest hundreth, Area = 9.42 in^2
