Cameron is a member of a national gardening club. she asked 200 of her fellow members whether they use compost to fertilize thei

krok68 [10]

Using the z-distribution, it is found that the 90% confidence interval for the true proportion of club members who use compost is (0.392, 0.508).

<h3>What is a confidence interval of proportions?</h3>

A confidence interval of proportions is given by:

$\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}$

In which:

$\pi$ is the sample proportion.

z is the critical value.

n is the sample size.

In this problem, we have a 90% confidence level, hence $\alpha = 0.9$ , z is the value of Z that has a p-value of $\frac{1+0.9}{2} = 0.95$ , so the critical value is z = 1.645.

The estimate and the sample size are given by:

$\pi = 0.45, n = 200$

Hence, the bounds of the interval are:

$\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.45 - 1.645\sqrt{\frac{0.45(0.55)}{200}} = 0.392$

$\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.45 + 1.645\sqrt{\frac{0.45(0.55)}{200}} = 0.508$

What value of x makes the equation true <br> 2 (6x-1) = -38

Anestetic [448]

Answer:

<h3> $\boxed{\bold{\boxed{ \sf{x = - 3}}}}$ </h3>

Step-by-step explanation:

$\sf{2(6x - 1) = - 38}$

Distribute 2 through the parentheses

⇒ $\sf{12x - 2 = - 38}$

Move constant to right hand side and change it's sign

⇒ $\sf{12x = - 38 + 2}$

Calculate

⇒ $\sf{12x = - 36}$

Divide both sides of the equation by 12

⇒ $\sf{ \frac{12x}{12} = \frac{ - 36}{12} }$

Calculate

⇒ $\sf{x = - 3}$

Hope I helped!

Best regards!!

Find the Expression OF this equation.<br>c/3 / ac/4<br><br>QUESTION C

Fiesta28 [93]

Answer:

See below

Step-by-step explanation:

$(a) \: \: x = \frac{c}{3} \\ \\ \implies \: {x}^{2} = { \bigg( \frac{c}{3} \bigg) }^{2} \\ \\ \bold{\implies \: {x}^{2} = \frac{ {c}^{2} }{9} } \\ \\ (b) \: \: x + y = \frac{c}{3} + \frac{ac}{4} \\ \\\implies \: \bold{x + y = \frac{4c + 3ac}{12} } \\ \\ \frac{xy}{z} = \frac{ \frac{c}{3} \times \frac{ac}{4} }{ \frac{ {a}^{2} }{2c + 1} } \\ \\ = \frac{ \frac{ac ^{2} }{12} }{ \frac{ {a}^{2} }{2c + 1} } \\ \\ = \frac{a {c}^{2} }{12} \times \frac{2c + 1}{ {a}^{2} } \\ \\ \implies\bold{\frac{xy}{z} = \frac{ {c}^{2}(2c + 1) }{12a} }$
