Answer:

Step-by-step explanation:

6). Equation of the line has been given as,

    4x + 9y = -9

    By converting this equation into y-intercept form,

    9y = -4x - 9

    [tex]y=-\frac{4}{9}x-\frac{9}{9}[/tex]

    [tex]y=-\frac{4}{9}x-1[/tex]

    By comparing this equation with y = mx + b

    Here, m = Slope of the line

    b = y-intercept

    Slope of the equation (m) = [tex]-\frac{4}{9}[/tex]

    y-intercept (b) = -1

8). Equation of the line is,

    5x + 3y = 12

    3y = -5x + 12

    [tex]y=-\frac{5}{3}x+\frac{12}{3}[/tex]

    [tex]y=-\frac{5}{3}x+4[/tex]

    Slope of the line = [tex]-\frac{5}{3}[/tex]

    y-intercept = 4

which of the following r-values represents the strongest correlation?

A.-0.61
B.-0.51
C.-0.81
D-0.71

Answers

The r-value that represents the strongest correlation is -0.81 (option C). Details about correlation coefficient can be found below.

What is correlation?

Correlation coefficient is any of the several measures indicating the strength and direction of a linear relationship between two random variables.

The correlation coefficient is denoted by r. A r-value can either be negative or positive depending on the direction of the relationship.

However, the closer a r-value is to 1, the stronger the relationship. This means that a r-value of -0.81 represents the strongest correlation.

This table shows a value that represents an exponential function what is the average rate of change for this function for the interval from x=3 to x=5?

Answers

Answer:

C

Step-by-step explanation:

The average rate of change on an interval is simply the slope between the endpoints.

We want to find the average rate of change of function y from x= 3 to x = 5.

Find the endpoints. From the table, we know that the endpoints are (3, 27) and (5, 125).

The slope between them is:

[tex]\displaystyle m=\frac{125-27}{5-3}=49[/tex]

So, the average rate of change of function y from x = 3 to x = 5 is 49.

Our answer is C.
