PLEASEEE HELP I WILL MARK YOU BRAINIEST!!!

Answer:

The possibility of rolling a  

3

on a fair die and getting tails on a coil is  

1

12

. Based on this probability, there are  

12

possible outcomes. As only 1 out of 12 possiblities would get this outcome, it is not a likely outcome.

Step-by-step explanation:

The probability of rolling a  

3

on a fair die is  

1

6

because there is only one  

3

out of  

6

numbers. The probability of getting tails on a coin is  

1

2

because there are  

2

possibilities and tails is one of them. To get the probability of rolling a  

3

on a fair die and getting tails on a coil, we multiply their probabilities:

1

6

⋅

1

2

=

1

12

There are  

12

possiblities because for each of the  

6

possibilites for rolling a die, there are  

2

possibilites for flipping a coin.

Answer:

a) 0.0879 = 8.79% probability the detector will identify a random mile of roadway as irregular.

b) 0.3379 = 33.79% probability it actually is irregular

Step-by-step explanation:

Conditional Probability

We use the conditional probability formula to solve this question. It is

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]

In which

P(B|A) is the probability of event B happening, given that A happened.

[tex]P(A \cap B)[/tex] is the probability of both A and B happening.

P(A) is the probability of A happening.

a. What is the probability the detector will identify a random mile of roadway as irregular?

99% of 3%(it is irregular).

6% of 97%(false positive). So

[tex]p = 0.99*0.03 + 0.06*0.97 = 0.0879[/tex]

0.0879 = 8.79% probability the detector will identify a random mile of roadway as irregular.

b. Given a randomly selected miles has been identified as irregular by the detector, what is the probability it actually is irregular? Give your answer to four decimal places.

Conditional probability:

Event A: Identified as irregular

Event B: It is irregular.

0.0879 = 8.79% probability the detector will identify a random mile of roadway as irregular, which means that [tex]P(A) = 0.0879[/tex]

99% of 3% arre irregulars identified as, which means that [tex]P(A \cap B) = 0.03*0.99 = 0.0297[/tex]

The desired probability is:

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.0297}{0.0879} = 0.3379[/tex]

0.3379 = 33.79% probability it actually is irregular

The surface area formula and a surface area calculator both gave this answer. Hope you do good on your assignment.

Hi there!

[tex]\large\boxed{P = 22 cm}[/tex]

To find the perimeter, we must find the length of the rectangle.

We know the area is 24, thus:

A = l × w

24 = l × 3

24/3 = l = 8 cm

Find the perimeter using the formula:

P = 2l + 2w

Plug in the solved length and width:

P = 2(8) + 2(3) = 16 + 6 = 22 cm.

Step-by-step explanation:

Answer: D. There is a negative linear relationship between the mean number of triples per game and year.

Step-by-step explanation: This claim is supported by the interval. The interval contains plausible values for the slope of the linear regression line relating year and mean number of triples per game. Since all the values in the interval are negative, the interval supports the claim that increases in the year are associated with decreases in the mean number of triples per game.

Answer: 8 days

Step-by-step explanation:

K=14+8x

J=35+5x

when K=J they will have the same amount

14+8x=35+5x

8x=21+5x

3x=21

x=7 days until they have the same amount- 8 days until she has more

Answer:

Step-by-step explanation:

We are told that the costs add up this way:

  trip cost = bus rental + 2 × (cost of play)

Given that ...

The above equation can be rewritten as ...

  65 = 10 + 2x . . . . . . the desired equation

__

Solving for x, we have ...

  55 = 2x . . . . subtract 10

  27.50 = x . . . . divide by 2

The cost of one play is $27.50.

Answer:

[tex]A = 2B[/tex]

[tex]A + B = 25[/tex]

Step-by-step explanation:

Given

The first statement implies that:

[tex]X = A + B[/tex] i.e the components of X

Reading further, we have:

[tex]X = 45[/tex] ---- The mass of X

[tex]A = 2B[/tex] --- The relationship between [tex]A\ and\ B[/tex]

Required

Two equations to represent the scenario

The two equations are:

[tex]A = 2B[/tex] --- The relationship between [tex]A\ and\ B[/tex]

[tex]X = A + B[/tex] i.e the components of X

Substitute 25 for X in the second equation

[tex]25 = A + B[/tex]

[tex]A + B = 25[/tex]

So, the equations are:

[tex]A = 2B[/tex]

[tex]A + B = 25[/tex]

Step-by-step explanation:

Given

[tex]\triangle ABC[/tex]

[tex]\angle A = 10[/tex]

[tex]\angle B = 145[/tex]

Required

Similar [tex]\triangle[/tex] to [tex]\triangle ABC[/tex]

The question is incomplete as the other triangles to make comparison from, are not given.

However, general information that could help you are as follows.

The given parameters show that we have to consider AA criterion for selecting similar triangles.

So, you need to check the [missing] given triangles, and pick any that have 10 and 145 (in that particular order) as measures of two of its angles.

Take for instance.

[tex]\triangle DE\ F[/tex]

Where

[tex]\angle D = 10[/tex]

[tex]\angle E = 145[/tex]

See that:

[tex]\angle D = 10[/tex] is similar to [tex]\angle A = 10[/tex]

[tex]\angle E = 145[/tex] is similar to [tex]\angle B = 145[/tex]

This means that:

[tex]\triangle DE\ F[/tex] is similar to [tex]\triangle ABC[/tex] by AA
