an without replacement, what is the probability that the first 2 selected are white and the last 2 black?

Answers

Answer 1

There is a 0.99% chance of getting the first 2 white and the last 2 black if you draw 4 balls without replacement from a bag containing 10 white and 20 black balls.

If there are W white balls and B black balls in a bag, and you are drawing 4 balls without replacement, the probability that the first 2 selected are white and the last 2 black can be calculated as follows:

[tex]P(WWBB) = (W/ (W + B)) * ((W-1) / (W + B - 1)) * (B / (W + B - 2)) * ((B-1) / (W + B - 3))[/tex]

So, for example, if there are 10 white balls and 20 black balls, then the probability of getting the first 2 white and the last 2 black is:

[tex]P(WWBB) = (10 / 30) * (9 / 29) * (20 / 28) * (19 / 27) = 0.0099[/tex]

This means that there is a 0.99% chance of getting the first 2 white and the last 2 black if you draw 4 balls without replacement from a bag containing 10 white and 20 black balls.

one fruit punch has fruit juice and another is fruit juice. how much of the punch should be mixed with of the punch to create fruit punch that is fruit juice?

Answers

The below calculation allows us to determine the amount of fruit juice and punch needed to create a fruit punch that is entirely fruit juice.

To create a fruit punch that is entirely fruit juice, we must calculate the ratio of fruit juice to total punch. To do this, we will use the following formula:

Fruit Juice Ratio = (Fruit Juice / (Fruit Juice + Punch)) x 100

For example, if we have 10 ounces of fruit juice and 10 ounces of fruit punch, the ratio of fruit juice to total punch is 50%. Therefore, we need to mix 50% fruit juice with 50% punch to create a fruit punch that is entirely fruit juice.

To calculate this for any given amount of fruit juice and punch, we simply plug the numbers into the formula. For instance, if we have 20 ounces of fruit juice and 60 ounces of punch, the ratio of fruit juice to total punch is 25%. Therefore, we need to mix 25% fruit juice with 75% punch to create a fruit punch that is entirely fruit juice.

By using this formula, we can easily determine the amount of fruit juice and punch needed to create a fruit punch that is entirely fruit juice.

We can use the formula Fruit Juice Ratio = (Fruit Juice / (Fruit Juice + Punch)) x 100 to calculate the ratio of fruit juice to total punch. This allows us to determine the amount of fruit juice and punch needed to create a fruit punch that is entirely fruit juice.

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

Female colorblindness proportion = 1%

Male colorblindness proportion = 8%

Female sample size = 40

Male sample size = 20

Hence, We get;

Let us check if the condition np ≥ 10 is satisfied or not,

⇒ np

⇒ 40 × 0.01

⇒ 0.4 < 10

Since, the condition np ≥ 10 is not satisfied the binomial random variable cannot be well approximated by a normal random variable. A larger sample size would be required to satisfy the condition np ≥ 10.

Hence, The mean is,

μ = np

μ = 40*0.01

μ = 0.40

And, The standard deviation is,

σ = √p(1 - p)/n

σ = √0.01(1 - 0.01)/40

σ = 0.015

naruto practices his harmonica 1/4 hour, spends 2/3 hour working on homework and takes another 1/2 hour to do chores everyday. how much longer does naruto spend practicing his harmonica and doing his chores than working on homework?

(1/4 + 1/2) - 2/3

Answers

(1/4 + 1/2) - 2/3 is the question i will be solving for you.

Step by Step:

You always want to start with the parentheses according to the PEMDAS rule. (Parentheses, Exponents, Multiply or Divide, Add or Subtract)

So, you first will do (1/4 + 1/2). They do not have the same denominator so you will find the common denominator.

If we want the denominator to be the same, we know we can do 1/2 × 2/2 because it'll make both denominators the same.
2 × 2 = 4
1 × 2 = 2

Now, our equation is (2/4 + 1/4) - 2/3.

Let's solve the equation in the parentheses.
2 + 1 = 3
The denominator stays 4.

Now, our equation is 3/4 - 2/3.
The denominator are not the same. So, our common denominator is going to be 12.

4: 4, 8, 12
3: 3, 6, 9, 12

To get the fractions to have the same denominator:

3/4 × 3/3 = 9/12
2/3 × 4/4 = 8/12

Now, our equation is 9/12 - 8/12.

9 - 8 = 1
The denominator stays the same.

So, (1/4 + 1/2) - 2/3 = 1/12.

During a football play, Odell Beckham Jr. Runs a straight route 40 yards up the sideline before

turning around and catching a pass thrown by Eli Manning. On the opposing team, a

defender who started 20 yards across the field from Beckham saw the play setup and ran a

slant towards Beckham What was the distance the defender had to run to get to the spot

where Beckham caught the ball?

Answers

The distance the defender had to run to get to the spot where Beckham caught the ball is 34.6 yards.

Let's call the distance the defender had to run to get to the spot where Beckham caught the ball "d".

Since the defender was running aslant towards Beckham, we can use the Pythagorean theorem to find the distance he had to run. The theorem states that in a right triangle, the sum of the squares of the two smaller sides is equal to the square of the hypotenuse (the longest side).

If we call the sideline 40 yards, we can set up the equation as follows:

d² + 20² = 40²

Expanding and simplifying:

d² + 400 = 1600

d² = 1600 - 400 = 1200

d = √(1200)

= √(300 * 4)

= √(300) * √(4)

= √(300) * 2

= 10 √(3) * 2

= 20 √3

Rounding to the nearest tenth, we have:

d ≈ 34.6 yards

So, the defender had to run approximately 34.6 yards to get to the spot where Beckham caught the ball.

a tank contains 1000 l of brine with 15 kg of dissolved salt. pure water enters the tank at a rate of 10 lymin. the solution is kept thoroughly mixed and drains from the tank at the same rate. how much salt is in the tank (a) after t minutes and (b) after 20 minutes?

Answers

The salt is in the tank (a) after t minutes is 20 minutes and (b) after 20 minutes there are 150 kg of salt.

Salt in Brine Tank Calculation

Let's call the amount of salt in the tank after t minutes "S(t)".

Since pure water is entering the tank and brine is leaving at the same rate, the volume of the solution in the tank remains constant at 1000 liters.

However, the concentration of salt in the solution is changing over time. At any given time, the amount of salt in the tank can be found by multiplying the volume of the solution by its concentration, which we can call "C(t)".

So, we have:

        S(t) = C(t) * 1000

The rate of change of salt in the tank is equal to the rate at which salt is entering the tank (from the dissolved salt in the brine that is leaving the tank) minus the rate at which salt is leaving the tank (from the brine that is leaving).

        dS(t)/dt = (C(0) - C(t)) * 10

         where C(0) is the initial concentration of salt in the

         brine (15 kg / 1000 liters = 0.015 kg/liter).

We can solve this differential equation to find the concentration of salt in the tank as a function of time. However, this can be a bit complicated, so let's just consider the answer for the specific times asked:

(a) After 20 minutes, we have:

        C(20) = C(0) - (S(20) / 1000 - S(0)) / 10

                  = 0.015 - (S(20) / 1000) / 10

And (b) the amount of salt in the tank after 20 minutes is:

        S(20) = C(20) * 1000

Plugging in the value of C(20) from part (a), we get:

        S(20) = (0.015 - S(20) / 1000 / 10) * 1000

        S(20) = 15 - S(20) / 10

        S(20) = 150

So, after 20 minutes, there are 150 kg of salt in the tank.

Answers

The Histogram shows the distribution of the students’ balance-scale readings is Histogram II.

The distribution of numerical data is roughly shown by a histogram. Karl Pearson was the one who initially coined the phrase. The first stage in creating a histogram is to "bin" (or "bucket") the range of values, or split it into a series of intervals, and then count the number of values that fall into each interval.

The bins are often defined as a series of discrete intervals that don't overlap. The bins (intervals) must be close together and frequently, but not always, have the same size.

When the mean and median are equal, a histogram is said to be symmetrical. A symmetric histogram will be split into two equal halves if we draw a line through its centre. The two parts will be exact replicas of one another.

Now that we have 2r, we can substitute in d:

C=π•d

Answers

Hello,

Answer:

We can start by rationalizing the denominators of each fraction.

For the first fraction, we multiply the numerator and denominator by the conjugate of the denominator, which is √4 - √5:

1/√4+√5 = 1/√4+√5 × (√4 - √5)/(√4 - √5)

= (√4 - √5)/(4 - 5)

= (√4 - √5)/(-1)

For the second fraction, we multiply the numerator and denominator by √5 - √6:

1/√5+√6 = 1/√5+√6 × (√5 - √6)/(√5 - √6)

= (√5 - √6)/(5 - 6)

= (√5 - √6)/(-1)

We can do the same for the remaining fractions:

1/√6+√7 = (√6 - √7)/(-1)

1/√7+√8 = (√7 - √8)/(-1)

1/√8+√9 = (√8 - √9)/(-1)

Now we can simplify the expression:

1/√4+√5 + 1/√5+√6 + 1/√6+√7 + 1/√7+√8 + 1/√8+√9

= (√4 - √5)/(-1) + (√5 - √6)/(-1) + (√6 - √7)/(-1) + (√7 - √8)/(-1) + (√8 - √9)/(-1)

= (√4 - √5 + √5 - √6 + √6 - √7 + √7 - √8 + √8 - √9)/(-1)

= (√4 - √9)/(-1)

= √9 - √4

= 3 - 2

= 1

Therefore, the expression simplifies to 1, which is equal to the right-hand side of the equation.

There are 3 right triangles in the drawing below. They are all similar. Chose the correct
similarity statement.

Answers

The correct similarity of the triangles are JMK ~ LMK ~ JLM (option D)

What is similarity?

Two figures are considered to be "similar figures" if they have the same shape, congruent corresponding angles and equal scale factors. Equal scale factors mean that the lengths of their corresponding sides have a matching ratio.

Given that, there are 3 right triangles in the drawing given. They are all similar. we need to identify the correct similarity,

So, from the figure, if we separate each triangle,

We will get,

Triangles JLM, JMK and LMK

If we check,

They are showing true similarity by their figure (refer to diagram attached)

Hence, the correct similarity of the triangles are JMK ~ LMK ~ JLM (correct option is D)

ermias can paint a room in 8 hours. manuel can paint the same room in 6 hours. how long does it take for ermias and manuel to paint the room if they are working together?

Answers

It takes Ermias and Manuel 3.43 hours to paint the room if they are working together. To find the time it takes for Ermias and Manuel to paint the room together, we can use the formula: 1/rate = time.

The rate is the combined painting rate of both workers, which is equal to the sum of their individual painting rates.

Let's call the time it takes for Ermias and Manuel to paint the room together "T". The combined painting rate of both workers is then 1/T.

The individual painting rates of Ermias and Manuel are 1/8 hours per room and 1/6 hours per room, respectively. Therefore, their combined painting rate is 1/8 + 1/6 = 6/48 + 8/48 = 14/48 hours per room.

Now we can use the formula 1/rate = time to find T:

1/ (14/48) = T

48/14 = T

T = 3.43 hours

So it takes Ermias and Manuel 3.43 hours to paint the room if they are working together.

Which fee pays for services such as a credit score check, an attorney, and a notary?

Answers

Typically, these services are covered by closing costs associated with a real estate transaction. Closing costs are fees charged by various parties involved in the home-buying process and can include the cost of a credit score check, attorney fees, and notary fees.

A credit score check is often required by a lender as part of the mortgage approval process, and the fee for this service can be included in the closing costs. The fee for an attorney can also be included in closing costs, especially if the attorney is hired to review and explain the closing documents. An attorney can also represent the buyer or the seller during the closing process and advise them of their rights and obligations.

A notary is typically required to witness the signing of legal documents, such as the mortgage or deed, and a notary fee can also be included in the closing costs. The exact amount of each of these fees can vary, and it's common for buyers to receive an estimate of their total closing costs from their lender prior to closing.

It's important to note that closing costs are separate from the down payment and can add several thousands of dollars to the overall cost of buying a home, so it's a good idea for buyers to carefully review their closing cost estimate and understand what each fee covers.

is it possible to obtain a negative value of ss (sum of squares), variance, and standard deviation? why?

Answers

No, it is not possible to obtain a negative value for the ss, variance, or standard deviation. They represent the amount of spread in data, and the values are always positive or zero.

Sum of squares (SS) measures the deviation of each data point from the mean of the set, squared. The formula for SS is:

SS = Σ (X - μ)^2

Variance is the average of the sum of squares, and it is calculated by dividing the SS by the degrees of freedom (n-1), where n is the number of data points in the set:

Variance = SS / (n - 1)

Standard deviation is the square root of variance and it is a measure of how far each data point is from the mean of the set:

Standard deviation = √Variance

Since both variance and standard deviation are based on the sum of squares, which is always non-negative, variance and standard deviation are also always non-negative.
