Answer:

Step-by-step explanation:

A binomial distribution table is a table that lists the probabilities of obtaining a specific number of success outcomes in a fixed number of independent trials, given a constant probability of success in each trial. The binomial distribution is a discrete probability distribution that describes the number of success outcomes in a fixed number of independent trials with a binary outcome (success or failure).

The table lists the probabilities of obtaining k successes in n trials, where k is a non-negative integer and n is a positive integer. The probabilities are calculated using the binomial formula, which is given by:

P(k successes in n trials) = (n choose k) * p^k * (1 - p)^(n-k)

where (n choose k) is the number of ways to choose k success outcomes from n trials, p is the probability of success in each trial, and (1 - p) is the probability of failure in each trial.

Binomial distribution tables are useful for solving problems related to counting and probability, especially in situations where the number of trials is fixed and the probability of success is constant. They can also be used for hypothesis testing, calculating confidence intervals, and estimating population proportions in statistical applications.

Divide the number of micrometers by 10,000 to get the equivalent number of centimeters.

To convert micrometers to centimeters, you need to use the conversion factor between the two units. There are 10,000 micrometers in a centimeter.

Here are the steps to convert micrometers to centimeters:

1. Start with the number of micrometers you want to convert.
2. Divide the number of micrometers by 10,000 to get the equivalent number of centimeters.
3. The result is the number of centimeters equivalent to the given number of micrometers.

For example, if you want to convert 50,000 micrometers to centimeters, you would divide 50,000 by 10,000 to get 5 centimeters.

So, the conversion formula is:

centimeters = micrometers ÷ 10,000

Answer: D.) 14

Step-by-step explanation:

First, you first calculate the square root of 64 , this gives you 8

Next, you calculate the square root of 36, which gives you 6

Then, since you are asked to add the two, you add 8 + 6 since this is the simplified version of the original equation.

8 + 6 = 14

Therefore, your answer is D.) 14

Since, 1 JPY = 0.0077 USD in Jan 27, 2023 08:45 UTC

Therefore, based on above information :

800 Japanese Yen 5.93 US Dollar.

The yen is the official currency of Japan. It is the third most traded currency on the foreign exchange market, after the US dollar (USD) and the euro. It is also widely used as the third key currency after the US dollar and the euro.

After World War II, the yen lost much of its pre-war value. To stabilize the Japanese economy, the yen exchange rate was fixed at 360 yen per US dollar under the Bretton Woods system. When this system was abolished in 1971, the yen was devalued and became liquid. After peaking at 271 yen per dollar in 1973, the yen appreciated to 271 yen per dollar due to the oil crisis in 1973, reaching 227 yen per dollar in 1980.

Another option is to do the calculations manually using simple mathematical formulas. However, for this you need to know the current exchange rate. As of this writing, one yen is worth $0.007.

Once you know this information, multiply the amount in JPY by the current exchange rate.

The resulting number shows how much you need to spend on your trip in US dollars.

Manual Currency Conversion Example

Suppose you have 100,000 yen and want to calculate how much money you will need to travel to the United States. Using the current exchange rate, the conversion formula would be

100,000 yen x 0.007 = $700

The expected number of cars that are a color other than silver is 42 cars.

Option D is the correct answer.

The percentage means the required value out of 100.

It is calculated by dividing the required value by the total value and multiplying it by 100.

The percentage change is also calculated using the same method.

In percentage change, we find the difference between the values given.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

We have,

If 16% of the cars passing by are silver, then the percentage of cars that are not silver.

= 100% - 16%

= 84%.

If 50 cars are selected at random on one day, the expected number of cars that are a color other than silver is equal to the total number of cars (50) multiplied by the percentage of cars that are not silver (84%).

= 50 x 84%

= 50 x 0.84

= 42 cars

Therefore,

The expected number of cars that are a color other than silver is 42 cars.

The amount of white paint did she use to paint her bedroom walls is 6 21/40 or 6.525 pints.

To find the amount of white paint used, we first need to find the amount of blue paint used. Since 1/4 of the total amount of paint is blue, we can multiply the total amount of paint by its fraction, 1/4, to find the amount of blue paint:
Blue paint = 8.7 pints × 1/4 = 87/40 = 2.175 pints

Now, to find the amount of white paint used, we can subtract the amount of blue paint from the total amount of paint:
White paint = 8.7 pints - 2.175 pints = 261/40 = 6.525 pints

So, Araceli used 6.525 pints of white paint to paint her bedroom walls.

In fraction form, this can be written as 6525/1000 pints, or 6 21/40 pints.

The probability that Justen wins is 4/9.

The probability that Justen wins is determined by the likelihood that the highest number rolled on the two dice is a 1, 2, 3, or 4. To find this probability, we can first calculate the probability that the highest number rolled is a 5 or 6, which is what would cause Gaberil to win.

The probability of rolling a 5 or 6 on one die is 2/6, or 1/3. The probability of rolling a 5 or 6 on both dice is (1/3) * (1/3) = 1/9.

However, we also need to account for the possibility that one die rolls a 5 or 6 and the other does not.

This can happen in two ways: either the first die rolls a 5 or 6 and the second does not, or the first die does not roll a 5 or 6 and the second does.

The probability of each of these scenarios is (1/3) * (2/3) = 2/9.

So the total probability of Gaberil winning is 1/9 + 2/9 + 2/9 = 5/9.

Since there are only two possible outcomes (either Gaberil wins or Justen wins), the probability of Justen winning is 1 - the probability of Gaberil winning. So the probability of Justen winning is 1 - 5/9 = 4/9.

Therefore, the probability that Justen wins is 4/9.

Answer: A monomial representation is a way to express a polynomial as a product of powers of its variables, where each power is a non-negative integer. For example, the polynomial 2x^3 + 4x^2 - 6x + 8 can be represented as a monomial representation of (2x^3)(x^2)(-6x)(8).

Symmetric polynomials are polynomials that are invariant under permutation of their variables. A symmetric presentation is a way of expressing a symmetric polynomial as a sum of elementary symmetric polynomials, which are defined as the sum of all possible products of variables taken i at a time, where i ranges from 1 to the number of variables. For example, the symmetric polynomial x^3 + y^3 + z^3 can be expressed as a symmetric presentation of x + y + z.

Step-by-step explanation:

The time it takes is 2 seconds

To find the time that the balloons collided at the highest point, we need to find the vertex of the resulting quadratic function.

First, we can set the two functions equal to each other, since they represent the height of the two balloons at any given time:

-7x^2 + 26x + 3 = -6x^2 + 23x + 5

Simplifying and rearranging terms, we get:

-x^2 + 3x + 2 = 0

Now, we can use the quadratic formula to solve for x:

x = (-b ± sqrt(b^2 - 4ac)) / 2a

where a = -1, b = 3, and c = 2.

Plugging in these values, we get:

x = (-3 ± sqrt(3^2 - 4(-1)(2))) / 2(-1)

x = (-3 ± sqrt(1)) / (-2)

Simplifying further, we get:

x = (-3 ± 1) / (-2)

So, x can be either 1 or 2. However, we're only interested in the positive value for x since time cannot be negative.

Therefore, the time that the balloons collided at the highest point is:

x = 2 second
