The answer to your question is letter C. 7y³ + 7n²y² - 22y²

Step-by-step explanation:

y²(4y + 7n² + 2) - 3y² (-y + 8)

Multiply

4y³ + 7n²y² + 2y² + 3y³ - 24y²

Use the associative property for like terms

(4y³ + 3y³) + (2y² - 24y²) + 7n²y²

Simplify like terms

7y³ - 22y² + 7n²y² or 7y³ + 7n²y² - 22y²

Answer:

Step-by-step explanation:

The sample proportion $\hat p = \dfrac{50}{200}$

$\hat p = 0.25$

The null hypothesis and the alternative hypothesis:

$H_o: p = 0.20 \\ \\ H_1 : p > 0.20$

Thus; the test statistics is:

$Z = \dfrac{\hat p - p_o}{\dfrac{p_o(1-p_o)}{n} }$

$Z = \dfrac{0.25 -0.20}{\sqrt{\dfrac{0.20(1-0.20)}{200} }}$

$Z = \dfrac{0.05}{\sqrt{\dfrac{0.16}{200} }}$

$Z = \dfrac{0.05}{\sqrt{0.0008 }}$

$Z = 1.768$

P-value = 2 × P(Z< - 1.768)

From the z tables

P-value = 2 × 0.03853

P-value = 0.07706

Thus, the p-value is 0.05 < P-value < 0.10
