A measure of the strength of the relationship between two variables is referred to as the correlation coefficient.

To gauge the strength of the linear link between two variables, correlation coefficients are used.

A value of correlation coefficient less than zero denotes a negative association, while a value greater than zero denotes a positive relationship.

A zero correlation coefficient means there is no correlation between the two variables under comparison.

A crucial idea in building diversified portfolios that may better resist portfolio volatility is the concept of a negative correlation, often known as an inverse correlation.

Since calculating the correlation coefficient takes time, it is frequently done by entering data into a calculator, computer, or statistics application.

Concluimos que hay 8 libros de aritmética.

Sabemos que la relacion entre el número de libros de aritmetica y el total de libros es de 4 a 9.

Es decir, sí el número total de libros es N, entonces (4/9)*N de esos libros son de aritmética.

Sea X el número de libros de aritmética. Sabemos que hay 10 libros de algebra, entonces el número total N es:

N = 10 + X

Y usando la relación de arriba, podemos escribir:

X = (4/9)*N = (4/9)*(10 + X)

Ahora podemos resolver esto para X.

X*(9/4) = 10 + X

There are 104 cars in the parking lot.

According to statement there are between 90 and 115 cars on the lot.

So, {X| 90 < x < 115} (This renders an infinite solution set finite)

AND exactly one eight of them have a sticker on the back, so the total number of cars must be evenly divisible by eight.

X ∈ {96, 104, 112,}

AND exactly one fourth of the cars are green, so the number of cars must be evenly divisible by 4. Here all above written numbers are divisible by 4. So, find the mean to calculate the number of cars in the parking lot.

The store charged $24 for each pair of socks as the selling price.

Profit is the financial gain that is earned by a business or an individual after deducting all expenses from revenue. In other words, it is the amount of money that remains after all costs of producing and selling a product or service have been subtracted from the total revenue earned.

Revenue refers to the total amount of income earned by a business or an individual from the sale of goods or services during a specific period of time. It is the total amount of money that a business receives from its customers in exchange for its products or services.

In the given question,

Let's start by calculating the total revenue from the sale of 25 pairs of socks

Since the profit is 25% of the revenue, we can set up the equation:

Profit = 0.25 * Revenue

$150 = 0.25 * Revenue

Revenue = $150 / 0.25

Revenue = $600

The total revenue from selling 25 pairs of socks is $600.

To find the price per pair of socks, we can divide the revenue by the number of pairs:

Price per pair = Revenue / Number of pairs

Price per pair = $600 / 25

Price per pair = $24

Therefore, the store charged $24 for each pair of socks.

Answer:

7

Step-by-step explanation:

Whenever you shifting an exponential function to the left/right, you're going to generally have the equation: [tex]y=2^{x-k}[/tex] where k is the shift. So in this case we can think of x+3 as x and k as 10, since the shift is 10. This gives you the equation: (x+3) - 10, which simplifies to x-7, meaning the k value in this case is going go be 7. You can also think of it as already being shifted 3 units to the left, and you shift it 10 units to the right, that means this new function will be shifted 7 units to the right relative to the origin. This means the k=7.

Answer:

Step-by-step explanation:

[tex]\text{Let the coordinates of B } = x_{B} , y_{B} \\\text{Let the coordinates of A} = x_{A} , y_{A} \\\text{Let the coordinates of midpoint M} = x_{M} , y_{M}[/tex]

By the midpoint formula,
[tex](x_{M},y_{M}) = (\frac{x_{A} + x_{B}}{2} , \frac{y_{A} + y_{B}}{2} )[/tex]

[tex]x_{M} = \frac{x_{A} + x_{B}}{2} \\y_{M} = \frac{y_{A} + y_{B}}{2} \\[/tex]

We have coordinates of midpoint as (5, 6) and coordinates of A as (3,8)
So
[tex]5 = \frac{3 + x_{B}}{2} \\\\\\textrm{Cross-multiplying } 10 = 3 + x_{B}} \textrm{ or } x_{B} = 10-3 = 7\\[/tex]

[tex]6 = \frac{8 + y_{B}}{2} \\\\\\\\textrm{Cross-multiplying } 12 = 8 + y_{B}} \textrm{ or } y_{B} = 12-8 = 4\\[/tex]

The 6th term of the sequence is 4

The given parameters are:

a1 = -4096

a4 = 64

The nth term of the sequence is:

a(n) = a1 * r^(n-1)

So, we have:

a4 = a1 * r^3

This gives

r^3 = a4/a1

Substitute the known values

r^3 = 64/-4096

Evaluate

r^3 = -1/64

Take the cube roots

r = -1/4

The 6th term is
