The amount in the account after 15 years after round of to the nearest hundredth is $6,671.67, the correct option is B.
How to find the compound interest?If n is the number of times the interested is compounded each year, and 'r' is the rate of compound interest annually, then the final amount after 't' years would be:
[tex]a = p(1 + \dfrac{r}{n})^{nt}[/tex]
We are given that;
The amount earned is A equal to P quantity 1 plus 0.054 over 2 end quantity all raised to the power of 2 times t
Rate of compound interest= 5.4%
Investment= $3000
Time= 15years
Now,
A = 3000(1+0.054/2)^2*15
A = 3000(1+0.054/2)^30
A = $6,671.67
So, amount = principal + interest
Principal = $3,000.00
Interest = $3,671.67
=$6,671.67
Therefore, the compound interest will be $6,671.67

Two water balloons were launched into the air at different moments and collided. The water balloons were modeled by the quadratic functions: y = −7x2 + 26x + 3 and y = −6x2 + 23x + 5, where y represents the height in meters and x represents the time in seconds after the launch. What is the time, in seconds, that the balloons collided at the highest point? 2.0 seconds 2.25 seconds 2.5 seconds 2.75 seconds
The time it takes is 2 seconds
What is the time the balloons collided at the highest point?
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
So, the correct answer is: 2.0 seconds

how much usd for 800 yen?
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

What is monomial representations and symmetric presentations?
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.

What is a percentage?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

Araceli uses 8. 7 pints of blue paint and white paint to paint her bedroom walls. 1/4
of this amount is blue paint, and the rest is white paint. How many pints of white paint did she use to paint her bedroom walls?
Express your answer in fraction and decimal form. Solve on paper. Then check your work on Zearn
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.
In decimal form, it is simply 6.525 pints.

What is binomial distribution table ?
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.

what is the that justen wins
The probability that Justen wins is 4/9.
Determine the probabilityThe 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.
