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.

If the odds in favor of an event E are a : b,

To find  the probability of event E is

Formula for Probability

The Probability formula is defined as the possibility of an event to happen is equal to the ratio of the number of favourable outcomes and the total number of outcomes.

Probability of event to happen P(E) = Number of favourable outcomes / total number of outcomes

Now, According to the question:

Here, Number of outcomes in favor of the event = a

Number of outcomes in against the event = b

Total Outcomes => a + b = c

Therefore, Probability of event E is = a/c

Using Chebyshev's Theorem, it is found that:

When the distribution is not normal, Chebyshev's Theorem is used. It states that:

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:

Hence:

According to Chebyshev's theorem, at least 56% of the home buyer's ages lie between 30 years and 60 years.

25 and 65 years are both 2 standard deviations from the mean, hence:

At least 75% of the home buyers' age lie between 25 years and 65 years.

To find out the coordinate of b  if M is the midpoint of AB. A(1, -4) and M(-3 ,0).

The midpoint is that point the line whose length from both the ends of the line is equal.

Here,

We have coordinates of two points i.e. A(1, -4) and M(-3, 0).

Definition of midpoint says,

x = [x₁ +  x₂] / 2 ; y = [y₁ + y₂] / 2

x₁ = 2, x = 4 , y₁ = -1, y = 4

now,

4 = [2 + x₂] / 2 ; 4 = [1 + y₂] / 2

x₂ = 8 - 2         ; y₂ = 8 - 1

x₂ = 6               : y₂ = 7

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:

We 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.

  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.

The 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).

There are 6,435 different selections of 7 bonsais that William Smith can choose.

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

The required measures of the corresponding parts in the reflection of figure a = 3.2 and b = 46 degrees. Option C is correct.

As given in the question, the figure on the left is reflected using a line to form the image on the right.

Here,
Since the reflection of a figure never changes its dimension so,
in the figure,
b + 143 + 108 + 63 = 360
b = 46
And also in reflection, the measure of the site will not change so the measure of a = 3.2
