Which expression is equivalent to...

torisob [31]

Answer:

$x^{\frac{2}{7} } y^{-\frac{3}{5} } \\$ i.e answer A.

Step-by-step explanation:

This question involves knowing the following power/exponent rule:

$\sqrt[n]{x^m} = x^\frac{m}{n} \\\\so \sqrt[7]{x^2} = x^\frac{2}{7} \\\\and \\\\ \sqrt[5]{y^3} = y^\frac{3}{5} \\$

Next, when a power is on the bottom of a fraction, if we want to move it to the top, this makes the power become negative.

so the y-term, when moved to the top of the fraction, becomes:

$y^{-\frac{3}{5} } \\$

So the answer is: $x^{\frac{2}{7} } y^{-\frac{3}{5} } \\$

Tpy6a [65]

Answer:

65.54% (nearest hundredth)

Step-by-step explanation:

Given:

$\sf \mu=9000$

$\sf \sigma=1000$

$\sf X \sim N(\mu, \sigma^2)\implies X \sim N(9000,1000^2)$

P(X > 8600) = 1 - P(X ≤ 8600)

= 1 - 0.3445782584

= 0.6554217416

= 65.54%
