Complete the following proof.

Ivan

Using the circle theorems, we have proven that m ∠RTW = 15°

<h3>Circle theorems </h3>

From the question, we are to prove that m ∠RTW = 15°

In the given diagram,

measure of arc ST = 30°

∴ m ∠SRT = 30°

m ∠SRT = ∠T + ∠W ( <em>Exterior angle of a triangle equals the sum of the two remote angles</em>)

Also,

∠T = ∠W (<em>Radii of the same circle</em>)

∴ m ∠SRT = ∠T + ∠T

m ∠SRT = 2 × ∠T

30° = 2 × ∠T

∠T = 30° /2

∠T = 15°

∴ m ∠RTW = 15°

Hence, we have proven that m ∠RTW = 15°

Leona [35]

Answer:

0.3876<p<0.4389

Step-by-step explanation:

-Given $n=2472, \ x=1022 , \ CI=0.99$

-We calculate the proportion of surveys returned:

$\hat p=\frac{1022}{2472}\\\\=0.4134$

For a 99% confidence interval:

$z_{\alpha/2}=2.576$

#The margin of error is calculated as;

$ME=z_{0.005}\times \sqrt{\frac{\hat p(1-\hat p)}{n}}\\\\=2.576\times \sqrt{\frac{0.4134(1-0.4134)}{2472}}\\\\=0.0255$

The confidence interval are then:

$CI=\hat p\pm ME\\\\=0.4134\pm 0.0255\\\\=[0.3876,0.4389]$

Hence, the confidence interval is 0.3876<p<0.4389

Can someone help me with this?

faltersainse [42]

Hello, the answer should be A,B and D options.

First, let's edit the given equations option-by-option.

<h2>Option A:</h2>

$-5x+12=5x+12$

$-5x-5x=-12+12$

$-10x=0$

$x=0$

There is only one solution which is $x=0$ .

<h2>Option B:</h2>

$-5x+12=5x-5$

$-5x-5x=-12-5$

$-10x=-17$

$x=\frac{17}{10}$

There is only one solution which is $x=\frac{17}{10}$ .

<h2>Option C:</h2>

$-5x+12=-5x-12$

$-5x+5x=-12-12$

$0\neq -24$

In Math, zero is <u>not equal to</u> minus twenty four ( $0\neq -24$ ) that's why we do not have any solution in this equation.

<h2>Option D:</h2>

$-5x+12=-12x-12$

$-5x+12x=-12-12$

$7x=-24$

$x=-(\frac{24}{7} )$

There is only one solution which is $x=-(\frac{24}{7} )$
