In a game called Taxation and Evasion, a player rolls a pair of dice. If, on any turn, the sum is 7, 11, or 12, the player gets

AnnZ [28]

Answer:

$Probability = \frac{243}{1024}$

Step-by-step explanation:

Given

$Sum = \{7, 11, 12\}$

$Rolls = 5$

Required

Probability of not getting audited

If a pair of dice is rolled, the following are the observations of the sum

$Outcomes = 36$

$Sum\ of\ 7 = 6$

$Sum\ of\ 11 = 2$

$Sum\ of\ 12 = 1$

So, in a single roll; The probability of getting audited is:

$p= \frac{1 + 2 + 6}{36}$

$p= \frac{9}{36}$

$p= \frac{1}{4}$

The probability of not getting audited in a single roll is:

$q = 1 - p$ --- Complement rule

$q = 1 - \frac{1}{4}$

Take LCM

$q = \frac{4 - 1}{4}$

$q = \frac{3}{4}$

The probability of not getting audited in 5 rolls is:

$Probability = q^5$

$Probability = (\frac{3}{4})^5$

$Probability = \frac{3^5}{4^5}$

$Probability = \frac{243}{1024}$

UNIT RATE TRUE OR FALSE HELP ME!!!

lara31 [8.8K]

Answer:

False

Step-by-step explanation:

This is not a unit rate because neither of the rates are equal to 1. A unit rate, for example, could be 25 ft per second.

For the line segment whose endpoints are A(0,0) and B(4, 3), find the x value for the point located

Crank

Answer:

Step-by-step explanation:

The distance between A and B is given by the Pythagorean Theorem:

$= \sqrt{(4-0)^{2}+(3-0)^{2}} = 5$

The angle of the line segment is:

$\theta = \tan^{-1}\left(\frac{3-0}{4-0} \right)\\\\\theta \approx 36.870^{\circ}$

The x-coordinate of the point is:

$x = 0 + \frac{2}{3}\cdot (5) \cdot \cos 36.870^{\circ}\\\\x = 2.667$

x≅ 2.7

What is the inverse of f(x)=5x-8

Ksju [112]

Answer:

$\large\boxed{f^{-1}(x)=\dfrac{1}{5}x+\dfrac{8}{5}}$

Step-by-step explanation:

$f(x)=5x-8\to y=5x-8\\\\\text{change}\ x\ \text{to}\ y\ \text{and vice versa}\\\\x=5y-8\\\\\text{solve for}\ y:\\\\5y-8=x\qquad\text{add 8 to both sides}\\\\5y-8+8=x+8\\\\5y=x+8\qquad\text{divide both sides by 5}\\\\\dfrac{5y}{5}=\dfrac{x}{5}+\dfrac{8}{5}\\\\y=\dfrac{1}{5}x+\dfrac{8}{5}$

У + 6x — 36 = 0 Solve for y

zalisa [80]

Answer:

y=-6x+36

Step-by-step explanation:

у + 6x — 36 = 0

-add 36 to both sides

y+6x=36

-subtract 6x from both sides

y=36-6x or y=-6x+36

-This should be the correct answer
