Answer:
B. -2/5
Step-by-step explanation:
For a "run" (x change) of 5, the "rise" (y change) is -2 units. Then the slope is ...
slope = rise/run = -2/5
Answer:
B. -2/5
Step-by-step explanation:
The description that best describes the strength and direction of the association between the variables is A. Strong positive.
A correlation is defined as a causative association between two or more variable, which can be used to make predictions about a given outcome.
The degree and direction of the link between the variables are best described by a strong positive correlation. R = 0.96 indicates that the independent variable raise the dependent variable by 0.96. R correlation ranges from 0 to 1, with 0 indicating the weakest connection and 1 indicating the strongest correlation.
As a result, 0.96 is a strong correlation. The correlation coefficient's minus and positive values indicate the direction of the relationship between the variables.

The x-coordinate of the point in the standard (x,y) coordinate plane at which the 2 lines y = 2x + 6 and y = 3x + 4 intersect is:
x=2
The point of intersection of the two lines is the point where the y-value of the two lines are equal.
Now, in order to find the x-coordinate of the point of intersection we equate the equation of two lines in terms of x and by some operation we obtain the value of x.
Here the equation of two lines are:
y = 2x + 6 and y = 3x + 4
Now, on equating the y-value we have:
2x+6=3x+4
Now,
3x-2x=6-4
i.e.
x=2
Also, on putting the value of x in any of the two equation of lines we have:
y=10
Hence, the point of intersection is: (2,10)
The required equation is: and the number of credit hours is 7.5
The functions are given as:
When the two tuition costs are equal, we have:
This gives
Collect like terms
Divide both sides by 20
Hence, the required equation is: and the number of credit hours is 7.5
