The relationship of the data can be classified as a fairly strong positive correlation.
What is positive correlation?
Correlation is a statistical measure used to measure the relationship that exists between two variables.
Positive correlation is when two variables move in the same direction. If one variable increases, the other variable also increases. When there is a positive correlation, the graph of the variables is upward sloping

find the equation of a line passing through the point(-3,0) and (2,-3)
Answers
Answer (assuming the question allows it to be written in slope-intercept form):
[tex]y = -\frac{3}{5} x-\frac{9}{5}[/tex]
Step-by-step explanation:
1) First, find the slope of the equation. Use the slope formula [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex], substitute the given points' x and y values, and simplify:
[tex]m = \frac{(-3)-(0)}{(2)-(-3)} \\m =\frac{-3-0}{2+3}\\m = -\frac{3}{5}[/tex]
Thus, the slope is [tex]-\frac{3}{5}[/tex].
2) Now, use the point-slope formula [tex]y-y_1 = m (x-x_1)[/tex] and substitute real values for [tex]m[/tex], [tex]x_1[/tex], and [tex]y_1[/tex].
Since [tex]m[/tex] represents the slope, substitute [tex]-\frac{3}{5}[/tex] in its place. Since [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of a point the line crosses, use the x and y values of any one of the given points to substitute into the formula. (Either one is fine. I chose (2,-3).) Then, isolate y to put it into slope-intercept form and find the answer:
[tex]y-(-3) = -\frac{3}{5} (x-(2))\\y + 3 = -\frac{3}{5} x + \frac{6}{5} \\y = -\frac{3}{5} x - \frac{9}{5}[/tex]

Martina bought 4 CDs that were each the same price. Including sales tax, she paid a total of $70.40 . Each CD had a tax of $ 1.10 . What was the price of each CD before tax?
Answers
[tex]1.10 \times 4 = 4.40[/tex]
[tex]70.40 - 4.40 = 66[/tex]
[tex]66 \div 4 = 16.5[/tex]
Each CD was $16.50 before tax
Proof
[tex]total \: cost = 16.5(4) + 1.10(4)[/tex]
[tex]total \: cost = 66 + 4.40[/tex]
[tex]total \: cost = 70.40[/tex]

Answers
Answer:
$30
Step-by-step explanation:
You need to figure out how the money changes between then and now. To do that, take now and divide it by then; 900,000/30,000 = 30, the amount now is 30 times that of then. To figure out what any amount then is worth now, multiply it by 30 and you'll get you answer. (In this case: 1*30 = 30)

Let's complete the square. We get:

(x^2-30x+225)+y^2+221-225=0
(x-15)^2+y^2-4=0
(x-15)^2+y^2=4
By analyzing this, we see that the radius is just :[tex]\sqrt{4}[/tex]=2

x = [tex]\sqrt{69}[/tex]
Step-by-step explanation:
Pythagorean theorem: A^2 + B^2 = C^2
first, find the length of the line cutting through the shape:
let's call this line L.
plug the numbers into the theorem.
4^2 + 2^2 = L^2
16 + 4 = L^2
20 = L^2
next, plug 7 and L into the theorem again to find x
L^2 + 7^2 = x^2
20 + 49 = x^2
69 = x ^2
x = [tex]\sqrt{69}[/tex]

Perpendicular, because two lines are considered perpendicular if their slopes are opposite reciprocals.
