Answer:

P = 0.545

Step-by-step explanation:

Here we can find the probability Q, in which you need one or two spins to win the game, and then:

P = 1 - Q

Will be the probability that it takes 3 or more spins to win.

Case where you need only one spin:

There are 3 out of 12 possible outcomes, then the probability of winning with only one spin is:

p = 3/12.

Case where you need two spins to win:

Here we should get a normal sushi roll in the first spin and a wasabi bomb in the second.

The probability of getting a sushi roll in the first spin is equal to the quotient between the number of sushi rolls (9) and the total number of possible outcomes (12), then:

p1 = 9/12

For the second spin we need to get a wasabi bomb, assuming that the susi roll is not replaced (so now there are 8 sections with sushi rolls and 3 with wasabi bombs, if you get the empty section you roll again or something like that)

Now the probability of getting a wasabi bomb is equal to the quotient between the number of wasabi bombs remaining (3) and the total number of outcomes remaining (11), this is:

p2 = 3/11

The joint probability is the product of the two individual probabilities:

p = p1*p2 = (9/12)*(3/11)

Now, the total probability of winning with one or two spins is equal to the sum of the probabilities for each case, then:

Q = (9/12)*(3/11)  + 3/12 = 0.455

Then the probability of needing 3 or more spins to win is:

P = 1 - Q = 1 - 0.455 = 0.545

The probability that it takes 3 or more spins for the contestant to get a wasabi bomb is 0.545 and this can be determined by using the given data.

Given :

The probability to win the game in the first spin is:

[tex]\rm P_1=\dfrac{3}{12}=\dfrac{1}{4}[/tex]

The probability to win the game in the second spin is:

[tex]\rm P_2 = \dfrac{9}{12}\times \dfrac{3}{11}[/tex]

[tex]\rm P_2=\dfrac{9}{44}[/tex]

The probability to win in 1 or 2 spins is given by:

[tex]\rm Q = P_1+P_2=\dfrac{9}{44}+\dfrac{1}{4}[/tex]

Q = 0.455

So, the probability that it takes 3 or more spins for the contestant to get a wasabi bomb is:

P = 1 - Q

P = 1 - 0.455

P = 0.545

Step-by-step explanation:

Price after the socks is marked up = $40 + $5 = $45

If the sock is discounted by 40%, the price of the socks would be 60% of the original price

0.6 x $45 = 27

The discounted price is $27

Answer:

10ft

Step-by-step explanation:

The length of one side of this cube would be the cube root of 1000 since each of the three dimensions are the same. You could solve this problem with the following equation, where [tex]l[/tex] is the side length.

[tex]l^3[/tex] = 1000

[tex]l[/tex] = [tex]\sqrt[3]{1000}[/tex]

[tex]l[/tex] = 10

So, the side length of the edge of the cube is 10ft.

Answer:

the answer is 53

Step-by-step explanation:

The system has an infinite number of solutions because the equations have the same slope and y-intercept, and the graph of the equations is the same line.

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

The system of equations is given in the question, as follows:

-3x + 3y = 12

y = x + 4

When all the given equations are drawn in the graph, then we get the Infinitely many solutions ordered pairs in the solution set of the given system.

Here, the graph of the equations is the same line because the equations have the same slope and the same y-intercept. The system has exactly Infinitely many solutions.

Therefore, the correct answer would be an option (D).
