Find each quotient. All final answers must be in simplest form.56x4y5 - 49x3y6 - 35x2y3 / 7x?y2 =A8x^2y^3 - 7y^4 - 5yB8x^2 y^3 - 7xy^4 + 5yC 8x^2y^3 - 7xy^4 - 5yD 8x^2y^3 + 7xy^4 - 5y

Answer

Option C is correct

8x²y³ - 7xy⁴ - 5y

Explanation

The equation to be solved or reduced is

(56x⁴y⁵ - 49x³y⁶ - 35x²y³)/7x²y²

More properly written, the equation is

To solve this, we will break the division down and have each term carry the denominator and use the laws of indices to reduce the powers

(C) Because the p-value is greater than α, we fail to reject the null hypothesis and cannot conclude that the average age of PlayStation users is different from the average age of Xbox users.

Step-by-step explanation:

The t-statistic for difference of mean is given by,

Using this formula, we get, t = 1.5342

Thus, p-value = 0.1322 with 64 degree of freedom.

and α = 0.10

Since, the p-value is greater than alpha (p > .05), then we fail to reject the null hypothesis, and we say  that the result is statistically non-significant.
