1. If DC is an angle bisector, what is the
measure of DCB?

2. Without constructing, will the incenter lie
inside or outside this triangle? Why or why
not?

Answers

Answer:

1.

∠DCB is the half of the measure of ∠ACB as the angle bisector DC cut it in two equal parts.

m∠DCB = 1/2m∠ACB m∠DCB = 1/2(101.31°) = 50.655°

2.

The incenter is the intersection of the angle bisectors.

All three angle bisectors lie inside the triangle, hence the incenter is always inside.

Answers

Answer: The answer is A

Step-by-step explanation:

In the Japanese game show Sushi Roulette, the contestant spins a large wheel that’s divided into 12 equal sections. Nine of the sections have a sushi roll, and three have a “wasabi bomb.” When the wheel stops, the contestant must eat whatever food is on that section. To win the game, the contestant must eat one wasabi bomb. Find the probability that it takes 3 or more spins for the contestant to get a wasabi bomb. Show your method clearly.

Answers

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 :

In the Japanese game show Sushi Roulette, the contestant spins a large wheel that’s divided into 12 equal sections. Nine of the sections have a sushi roll, and three have a wasabi bomb.When the wheel stops, the contestant must eat whatever food is on that section. To win the game, the contestant must eat one wasabi bomb.

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

A cube has a volume 1,000 cubic feet. What is the length of the edge of the cube. SHOW YOUR ANSWER

Answers

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.
