Answer:

The answer is "0.9258201 or $\bold{ \frac{0.36 -0.3}{\sqrt{\frac{0.3 \times 0.7 }{50}}}}$ ".

Step-by-step explanation:

$\to P= 30 \ \%\\\\ \to x= 18 \\\\ \to n=50\\\\\\\hat p= \frac{x}{n} = \frac{18}{50} = 0.36 \\\\\bold{Formula:}\\\\X= \frac{\hat p -p}{\sqrt{\frac{p \times (1-p)}{n}}}\\\\$

$= \frac{0.36 -0.3}{\sqrt{\frac{0.3 \times (1-0.3)}{50}}}\\\\= \frac{0.36 -0.3}{\sqrt{\frac{0.3 \times 0.7 }{50}}}\\\\= \frac{0.36 -0.3}{\sqrt{\frac{0.21}{50}}}\\\\= \frac{0.06}{\sqrt{0.0042}}\\\\= \frac{0.06}{0.064807407}\\\\= 0.9258201$

In 2–4, write Yes or No to indicate whether the expressions are equivalent. 2. 10x - 3 + 2x - 5 and 4(3x - 2) 3. 3y + 3 and 9(y

Dmitry [639]

Step-by-step explanation:

2. 10x - 3 + 2x - 5 and 4(3x - 2)

10x - 3 + 2x - 5

Upon simplifying;

10x + 2x - 3 - 5

12x - 8

4(3x - 2)

12x - 8

Both expressions are equivalent - Yes!

3. 3y + 3 and 9(y + 1/3)

9(y + 1/3)

upon simplifying;

9y + 9 (1/3)

9y + 3

3y + 3

Both expressions are not equivalent - No!

4. 6(3x + 1) and 9x + 6 + 9x

6(3x + 1)

upon simplifying;

6(3x) + 6 (1)

18x + 6

9x + 6 + 9x

Upon simplifying;

9x + 9x + 6

18x + 6

Both expressions are equivalent - Yes!
