William Smith is choosing artisan bonsai trees. She has 15 different variants of bonsai trees and would like
to use 7 of them. How many different selections of the 7 bonsai trees are possible?
There are 6,435 different selections of 7 bonsais that William Smith can choose.
How many different selections of the 7 bonsai trees are possible?If we have a set of N elements, the number of different combinations of K elements (such that K is equal to or smaller than N) of those N elements is given by:
C(N, K) = N!/( (N - K)!*K!)
In this case, we know that she has 15 different variants of bonsai and she wants to use 7, then:
N = 15
K = 7
Replacing these values in the above formula we will get the possible combinations of bonsais.
C(15, 7) = 15!/( (15 - 7)!*7!) = 15!/( 8!*7!) = (15*14*13*12*11*10*9)/(7*6*5*4*3*2*1) = 6,435

A computer user has downloaded 21 songs using an online file-sharing program and wants to create a CD-R with
11 songs to use in his portable CD player. If the order that the songs are placed on the CD-R is not important to
him, how many different CD-Rs could he make from the 21 songs available to him?
Answer:
If to create a CD 9 songs are needed and user have 19 songs then he can create 33522128640 such CD's if solving through permutations.
What is permutations?
It is basically an arrangement of objects in a certain order.It is expressed as n and it is equal to n!/(n-r)!.
How to calculate ways?
We have been given that user have 19 songs and 1 CD is made from 9 songs so the number of CD's which can be made is basically the number of ways these 9 songs are arranged from 19 songs in CD's. So, the number of CD's will be 19=19!/(19-9)!
=19!/10!
=19*18*17*16*15*14*13*12*11*10!/10!
=19*18*17*16*15*14*13*12*11
=335322128640 CD's
Hence 335322128640 CD's can be made from 19 songs by the user.

Suppose that these measures are valid for the population of all home buyers. Complete the following statements about the distribution of all ages of home buyers.
According to Chebyshev's theorem, at least 56% of the home buyer's ages lie between __ years and __ years. (Round your answer to the nearest whole number)
According to Chevyshev's theorem, at least what percent of the home buyers' age lie between 25 years and 65 years.
Using Chebyshev's Theorem, it is found that:
At least 56% of the home buyer's ages lie between 30 years and 60 years.At least 75% of the home buyers' age lie between 25 years and 65 years.What does Chebyshev’s Theorem state?When the distribution is not normal, Chebyshev's Theorem is used. It states that:
At least 75% of the measures are within 2 standard deviations of the mean.At least 89% of the measures are within 3 standard deviations of the mean.An in general terms, the percentage of measures within k standard deviations of the mean is given by [tex]P = 100(1 - \frac{1}{k^{2}})[/tex].For the first item, we first have to find k when P = 56, hence:
[tex]56 = 100\left(1 - \frac{1}{k^{2}}\right)[/tex]
[tex]1 - \frac{1}{k^{2}} = 0.56[/tex]
[tex]\frac{1}{k^2} = 0.44[/tex]
k² = 1/0.44
k = sqrt(1/0.44)
k = 1.5.
Within 1.5 standard deviations, hence the bounds are:
45 - 1.5 x 10 = 30 years old.45 + 1.5 x 10 = 60 yards old.Hence:
According to Chebyshev's theorem, at least 56% of the home buyer's ages lie between 30 years and 60 years.

A finance magazine did a survey and found that the average American family spends $1,600 on a summer vacation. If the distribution is normal with standard deviation $411, find the amount a family would have spent to be the 80th percentile.
Answer:
$1,945.91
Step-by-step explanation:
To find the amount a family would have spent to be at the 80th percentile, we can use the normal distribution.
If a continuous random variable X is normally distributed with mean μ and variance σ², it is written as:
[tex]\boxed{X \sim\text{N}(\mu,\sigma^2)}[/tex]
Given that the average spending on a summer vacation is $1,600 and the standard deviation is $411:
Mean μ = $1,600Standard deviation σ = $411We need to convert the problem to the standard normal distribution by calculating the z-score.
The z-score represents the number of standard deviations a data point is away from the mean. To find the z-score corresponding to the 80th percentile, we need to find the critical value or z-score that corresponds to an area of 0.80 under the standard normal curve.
Using a standard normal distribution table or a calculator, the z-score corresponding to an area of 0.80 is 0.84162084...
Next, we use the formula for the z-score:
[tex]\boxed{z = \dfrac{x - \mu}{\sigma}}[/tex]
where z is the z-score, x is the data point, μ is the mean, and σ is the standard deviation.
Substitute z = 0.84162084..., μ = 1600, σ = 411 into the z-score formula:
[tex]0.84162084... = \dfrac{x - 1600}{411}[/tex]
Solving for x:
[tex]x=1945.90616...[/tex]
Therefore, a family would have spent approximately $1,945.91 to be at the 80th percentile of spending on a summer vacation.
Answer:
$1,945.03
Step-by-step explanation:
To find the amount a family would have spent to be at the 80th percentile, we need to find the z-score that corresponds to the 80th percentile and then use that z-score to calculate the corresponding amount.
First, we find the z-score using the standard normal distribution table or a calculator:
z = InvNorm(0.8) ≈ 0.8416
Next, we use the formula for transforming a z-score to a raw score:
z = (x - μ) / σ
where x is the raw score, μ is the mean, and σ is the standard deviation.
Substituting the given values and solving for x, we get:
0.8416 = (x - 1600) / 411
x - 1600 = 0.8416 * 411
x - 1600 = 345.0256
x = 1945.0256
Therefore, a family would have spent about $1,945.03 to be at the 80th percentile.

The rectangular coordinate system shows the graph of the equations in a system of equations. Use the graph to determine the number of solutions for the system. If the system has only one solution, give its coordinates.
Answer:
A. The only solution is (-2, 1).
Step-by-step explanation:
Given a graph of two lines, you want the number of solutions to the system of equations the lines represent.
SolutionThe graph of an equation represents all of the points that satisfy that equation. When a system of equations has more than one equation, the set of points that satisfies all of the equations is the set of points where the graphs intersect (overlap) each other.
Here, the two straight lines intersect at exactly one point: (-2, 1). That one point represents the only solution to the system of equations.
The only solution is (-2, 1).
