When playing American​ roulette, the croupier​ (attendant) spins a marble that lands in one of the 38 slots in a revolving turnt

able. The slots are numbered 1 to​ 36, with two additional slots labeled 0 and 00 that are painted green. Consider the numbers 0 and 00 as neither even nor odd. Half the remaining slots are colored red and half are black. Assume a single spin of the roulette wheel is made. Find the probability of the marble landing on a 00 or even slot. The total number of outcomes is and the number of outcomes in the event is

Answer:

Check the explanation

Step-by-step explanation:

1) probability for odd or 00 = (18+1)/38 = 0.5

2) expected value can be calculated as follows :

14 * win probability - 13 * lose probability

=14 * (18/38) - 13*(20/38)

= -0.21

Answer:

-0.21

Step-by-step explanation:

Firstly the probability for odd or 00 = (18+1)/38 = 0.5

Therefore we can calculate our expected value as follows :

14 * win probability - 13 * lose probability

=14 * (18/38) - 13*(20/38)

Hence our Answer is = -0.21

Write an expression that is equivalent to 3/5 (3y+15)<br> 3/5y +9, 3/5y+15, 9/5y+9, 9/5y + 15?
NISA [10]
Given the expression

\frac{3}{5} (3y+15)

The expression that is equivalent to the given expression is given by:

\frac{3}{5} (3y+15)= \frac{9}{5} y+ \frac{3}{5} (15)= \frac{9}{5} y+9

describe how to transform (^5 square root x^7)^3 into an expression with a rational exponent. make sure you respond with complet
diamong [38]

Answer:

x^\frac{21}{5}

Step-by-step explanation:

We are given an expression and we have to transform it into an expression with exponent.

5th root of x can be written as x^\frac{1}{5}

(\sqrt[5]{x^7})^3\\\\((x^7)^\frac{1}{5} )^3


The powers outside will be multiplied as: (x^a)^b = x^{ab}

(x^\frac{7}{5} )^3\\x^\frac{7*3}{5}\\x^\frac{21}{5}


where the exponent is \frac{21}{5} and it is a rational number by definition of rational numbers

Line A: y=-1/2x+3
sashaice [31]
A) For the equation y=- \frac{1}{2}x+3, the slope is - \frac{1}{2}.
Slope-intercept form is y = mx + b, where m is slope and b is the y-intercept. This means that if m=- \frac{1}{2}, the slope is  - \frac{1}{2}.

B) Since this equation is in the same form, you just find what m is equal to.
Since m=2, that's the slope.

For the solution, set y=- \frac{1}{2}x+3 equal to y=2x-4, so it would be put together like this:
y=[tex]- \frac{1}{2}x+3=2x-4\\ -\frac{1}{2}=2x-7\\ 1\frac{1}{2}x=-7\\ x=-4.66667
So your answer is -4.667.

Tanveer bought 0.7 pounds of sliced ham at his local deli. If the deli charged $6.79 per pound, how much did Tanveer pay?
lubasha [3.4K]

Answer:

$4.75

Step-by-step explanation:

As the price per pound is a one-to-one ratio, one could just simply multiply by using: 0.7 lbs * ($6.79 / 1 lb) = $4.75/1 = $4.75
