Working with a sample rather than an entire population is often more practical and cost-effective. It can also be more accurate since it reduces the chances of sampling bias.

Additionally, it can be faster and more efficient since it requires less data and can be done in a shorter period. Furthermore, a sample can provide more insight into the population as a whole since it is representative of the population, and the results of a sample can be generalized to the entire population. Finally, working with a sample is more manageable and easier to analyze than working with an entire population. This is because a sample has fewer data points, which can make it easier to identify patterns and draw conclusions.

The domain and range of y = 5^x is all real numbers.

The domain of y = 5^x is all real numbers, x. There are no restrictions on the input value for x, so any real number can be used as the exponent.

The range of y = 5^x is all positive real numbers, y. This is because the base of the exponential function, 5, is positive and the exponent, x, can be any real number. As the exponent increases, the value of the function will also increase and the function will approach positive infinity. Similarly, as the exponent decreases, the value of the function will also decrease and approach zero. Therefore, the range of y = 5^x is all positive real numbers, y.

As given in the question,

Required line passes through the points :

( x₁ ,y₁ ) = ( -2 , 7 )

And the slope of the line is equal to 2

Standard form of the equation of the line is :

( y - y₁ ) / ( x - x₁ ) = ( y₂ - y₁ ) / ( x₂ - x₁ )

Here slope =  ( y₂ - y₁ ) / ( x₂ - x₁ )

                   = 2

Required equation of the line with given point and the slope is:

( y - 7 ) / ( x -(-2)) = 2

⇒ ( y - 7 ) / ( x + 2 ) = 2

⇒ ( y - 7 ) = 2 ( x + 2 )

⇒ y - 7 = 2x + 4

⇒ y = 2x + 11.

On simplifying the equation (x + 10)² = 256 the dimensions of the original photo is obtained as 6 inches by 6 inches.

What is an equation?

A mathematical definition of an equation is a claim that two expressions are equal when they are joined by the equals sign ("=").

The measure of side of original square photo is x.

The square photo is enlarged by adding 10 inches to it = x + 10

The area of the enlarged square photo is 256 in².

The formula for area of a square is = (side)²

So, the equation to find the side of original photo is -

(x + 10)² = 256

Apply the formula (a + b)² = (a² + 2ab + b²) on the left hand side -

x² + 20x + 100 = 256

x² + 20x + 100 - 256 = 0

x² + 20x - 156 = 0

Factorize the quadratic equation to find the value of x -

x² + 20x - 156 = 0

x² + 26x - 6x - 156 = 0

x(x + 26) - 6(x + 26) = 0

(x + 26) (x - 6)

x = -26, x = 6

Since the side of the square photo cannot be negative, so x = 6 is the correct answer.

The sides of the square are same.

Therefore, the original photo had measurements 6 inches by 6 inches.

Step-by-step explanation:

Given that installing 6 apps increases the Eric : Ian app ratio from 3:4 to 5:4, you want to know how many more apps Ian needs to install to have the same number as Eric.

We note that the number of apps representing Ian's apps remains at 4 in both ratios, but increasing Eric's apps by 6 changes his number of ratio units from 3 to 5, a change of 2 ratio units. That is, each ratio unit represents 3 apps.

Eric now has 1 more ratio unit (5) than Ian (4), so Ian needs to increase his number by 1 ratio unit, or 3 apps.

Ian must install 3 apps to have the same number as Eric.

__

Additional comment

To see how many actual apps we're talking about, multiply the ratios by 3. The initial Eric : Ian app ratio was 9 : 12. After Eric installed 6, it became (9+6) : 12 = 15 : 12. So, Ian needs to install 15-12 = 3 apps to have as many as Eric.

The only logarithmic function of the given options is y = log 0.25x, which is a function that expresses the logarithm of 0.25 times x. Logarithmic functions are inverse of exponential functions, and are represented by an equation of the form y = log bx, where b is the base of the logarithm.

1. The logarithmic function y = log 0.25x can be written as y = log(0.25) + log(x).

2. To calculate the value of y, first calculate the logarithm of 0.25: log(0.25) = -2.

3. Then calculate the logarithm of x: log(x) = log(x).

4. Finally, add these two values together to get the value of y: y = -2 + log(x).

The slope and y-intercept of a linear equation in two variables are two important characteristics of the equation that can be used to graph the equation on a two-dimensional coordinate system.

The slope of a linear equation in the form of y = mx + b is represented by the coefficient of x, which is m. The slope tells us the steepness of the line and the direction it is moving. If m is positive, the line slopes upward to the right, if m is negative, the line slopes downward to the right.

The y-intercept of a linear equation in the form of y = mx + b is represented by the constant term b. The y-intercept is the point where the line crosses the y-axis. It can be found by setting x=0 and solving for y.

On comparing the equations with the general equation of linear equation in two variables we get:

m1=2 and b1=-4

Using the foci and co-vertices, the equation of ellipse is  (x^2/9) + (y^2/9) = 1

An ellipse is defined as the set of all points such that the sum of the distances from the foci to the point is constant. The distance between the foci is 2*c, where c is the distance from the center to either focus.

Given that the foci are at (0, ±3) and the co-vertices are at (±3, 0), we know that the center of the ellipse is at (0, 0) and the distance between the foci is 2c

So the equation of the ellipse with foci at (0, ±3) and co-vertices at (±3, 0) can be written as:
