Answer:

0.002991

Step-by-step explanation:

Let

User is legitimate one = E₁

User is fraudulent one = E₂

User originates calls from two metropolitan = A

Therefore, according to the question

P(E₁) = 1 - 0.01% = 1 - 0.0001 = 0.9999

P(E₂) = 0.0001

P(A/E₁) = 1% = 0.01

P(A/E₂) = 30% = 0.30

Now,

P(E₂/A) = $\frac{P(E_2)\timesP(A/E_1)}{P(E_1)\timesP(A/E_1)+P(E_2)\timesP(A/E_2)}$

P(E₂/A) = $\frac{0.9999\times0.01}{0.0001\times0.01+0.0001\times0.3}$

P(E₂/A) = 0.002991

The height and weight of adults can be related by the equation y=48.3x−127 where x is height in feet and y is weight in pounds.

suter [353]

we conclude that the correct option is A, the slope is:

<em>"the average number of pounds per foot tall"</em>

<h3>What does the slope of the line represent?</h3>

The linear equation:

y = 48.3*x - 127

Relates the height, x, and the weight, y of an adult.

Then the slope, which is 48.3, should have units of mass over height.

Now, if x is in feet and y is in pounds, then the slope has units of pounds/feet.

Then it represents the mean number of pounds per feet. So we conclude that the correct option is A:

"the average number of pounds per foot tall"

Hello there. May somebody help me simplify this problem? It would be very kind.

marissa [1.9K]

Answer:

27 / (4x⁶y⁸)

Step-by-step explanation:

$\frac{4(3x^{2}y^{4})^{3}}{(2x^{3}y^{5})^{4}}$

When raised to a power, multiply the exponents.

$\frac{4(3^{3}x^{6}y^{12})}{2^{4}x^{12}y^{20}} \\\\\frac{2^{2}3^{3}x^{6}y^{12}}{2^{4}x^{12}y^{20}}$

When dividing, subtract the exponents.

$2^{2-4}3^{3}x^{6-12}y^{12-20}\\2^{-2}3^{3}x^{-6}y^{-8}$

Move negative exponents to the denominator.

$\frac{3^{3}}{2^{2}x^{6}y^{8}}\\\frac{27}{4x^{6}y^{8}}$
