Answer:

Correlation analysis is used to quantify the degree to which two variables are related.

Step-by-step explanation:

In research, correlation analysis is a statistical approach for calculating and measuring the strength of a linear relationship between two variables. Simply defined, correlation analysis determines how much one variable changes as a result of the change in the other. A high correlation indicates a strong association between two variables, whereas a low correlation indicates a weak relationship.

The distance will remain constant. Then the time taken by Adam with an average speed of 60 miles per hour is 9 hours.

The distance covered by the particle or the body in an hour is called speed. It is a scalar quantity. It is the ratio of distance to time.

We know that the speed formula

[tex]\rm Speed = \dfrac{Distance}{Time}\\\\\\[/tex]

The formula can be written as

Distance = Speed × Time

The time it takes Adam to drive to Disney World varies inversely with his average rate of speed.

If it takes Adam 10.8 hours at an average speed of 50 miles per hour.

If the average speed is 60 miles per hour, then the time taken will be

The distance will remain constant.

S₂ × T₂ = S₁ × T₁

60 × T₂ = 50 × 10.8

A central tendency is a central or typical value for a probability distribution. Colloquially, measures of central tendency are often called averages. The term central tendency dates from the late 1920s. The most common measures of central tendency are the arithmetic mean, the median, and the mode.

The sides of the shaded triangle do not form a Pythagorean triple, therefore, it is not a right triangle.

A triangle is a right triangle if the square of its longest side equals the sum of the square of the other two smaller sides, based on the Pythagorean Theorem.

Using the Pythagorean Theorem, find the lengths of the legs of the shaded triangle, and find out the sum of their squares equals the length of the longest side.

First leg of the shaded triangle = √(8² + 6²) = 10

Second leg of the shaded triangle = √(8² + 9²) = 12

The third side (longest side) of the shaded triangle is 9 + 6 = 15.

15² = 10² + 12²

225 = 244 (not true)

Therefore, the shaded triangle is not a right triangle.

Answer:

Below.

Step-by-step explanation:

f(x)=3x^2-6x-45/x^2-5x

= 3x^2-6x-45 / (x(x - 5))

The denominator is zero when x - 0 and x = 5.

So there will be a vertical asymptote  at x = 0 and a hole at x = 5.

If we do the division  we get f(x)  = 3  remainder 9x - 45

so there will also be a horizontal asymptote where x = 3.

Answer:

Hole at (3, 4.8)

Asymptotes at x = 0 and y = 3

Step-by-step explanation:

[tex]f(x)=\dfrac{3x^2-6x-45}{x^2-5x}[/tex]

Factor the numerator:

[tex]\implies 3x^2-6x-45[/tex]

[tex]\implies 3(x^2-2x-15)[/tex]

[tex]\implies 3(x^2+3x-5x-15)[/tex]

[tex]\implies 3(x(x+3)-5(x+3))[/tex]

[tex]\implies 3(x-5)(x+3)[/tex]

Factor the denominator:

[tex]\implies x^2-5x[/tex]

[tex]\implies x(x-5)[/tex]

Factored form of function:

[tex]\implies f(x)=\dfrac{3(x-5)(x+3)}{x(x-5)}[/tex]

Discontinuity: a point at which the function is not continuous.

Holes

After factoring the rational function, if there is a common factor in both the numerator and denominator, there will be a hole at that point (x-value):

[tex]\implies (x-5)=0 \implies x=5[/tex]

Factor out the common factor from the function and input the found value of x into the new function to find the y-value of the hole:

[tex]\implies f(x)=\dfrac{3(x+3)}{x}[/tex]

[tex]\implies f(5)=\dfrac{3(5+3)}{5}=4.8[/tex]

Therefore, there is a hole at (5, 4.8)

Asymptotes

To find the vertical asymptotes, set the denominator of the new (factored) function to zero and solve:

⇒ Vertical Asymptote at x = 0

As the degrees of the leading terms of the numerator and denominator are equal (both x²), the horizontal asymptote is equal to the ratio of the leading coefficients.

⇒ Horizontal Asymptote at y = 3

Answer:

C. 32%

Step-by-step explanation:

The percent 17 is of 25.

17 of 25 can be written as:

17/25

To find percentage, we need to find an equivalent fraction with denominator 100. Multiply both numerator & denominator by 100

17/25 * 100/100

= (17 * 100/25) * 1/100 = 68/100

Therefore, the answer is 68%

If Sara made 68% of her free shows, that means she didn't make 32% of her free throws (100 - 68 = 32).
