Answer:

The pooled estimate is given by the following formula:

\hat p= \frac{x_1 +x_2 }{n_1 + n_2}

And replacing we got:

\hat p= \frac{42+45}{100+100}= \frac{87}{200}= 0.435

Step-by-step explanation:

We have the following info given:

n1 = 100,

n2 = 100,

x1 = 42,

x2 = 45

The pooled estimate is given by the following formula:

\hat p= \frac{x_1 +x_2 }{n_1 + n_2}

And replacing we got:

\hat p= \frac{42+45}{100+100}= \frac{87}{200}= 0.435

Write and then solve for y = f(x) the differential equation for the statement: "The rate of change of y with respect to x is inv
vazorg [7]
The statement "<span>The rate of change of y with respect to x is inversely proportional to y^4" can be written mathematically as dy/dx = k/y^4

To solve the differential equation, we use variable saparable method.
y^4 dy = kdx
Integrating both sides gives,
y^5 / 5 = kx + A
y^5 = 5kx + 5A = Bx + C; where B = 5k and C = 5A
y= \sqrt[5]{Bx+C}</span>
