Answer: C. Weak Positive

Step-by-step explanation:

In a scatter plot , a positive correlation is a relationship between the two variables x and y in which if value at x axis increases, then other value at y axis also increases.

In the given scatter plot the the association between variables x and y is a weak positive correlation because there is a lower likelihood in the relationship between variables.

What is the sum? 3 y / Y 2 + 7 y + 10 + 2 / y + 2

kap26 [50]

Answer:

5/(y+5)

Step-by-step explanation:

Perhaps you want the sum ...

$\dfrac{3y}{y^2+7y+10}+\dfrac{2}{y+2}\\\\=\dfrac{3y}{(y+2)(y+5)}+\dfrac{2(y+5)}{(y+2)(y+5)}=\dfrac{3y+2(y+5)}{(y+2)(y+5)}\\\\=\dfrac{5y+10}{(y+2)(y+5)}=\dfrac{5(y+2)}{(y+2)(y+5)}=\boxed{\dfrac{5}{y+5}}$

<em>Comment on rational expressions</em>

When writing ratios in plain text, it is imperative to put parentheses around numerators and denominators. (If the numerator is a product only, then parentheses are optional.)

Your expression might be properly written as ...

3y/(y^2 +7y +10) +2/(y+2)

As you have written it, it simplifies to ...

3(y/y)2 +7y +10 +2/y +2 = 3·2 +7y +2/y +12

= 7y +2/y +18

Please note, too, the exponentiation symbol (^).

How can you describe the line that passes through (0,3) and (-1, 0)

julia-pushkina [17]

let's find the equation of line passing through those two points.

slope of the given line :

$\dfrac{y_2 - y_1}{x_2 - x_1}$

$\dfrac{3 - 0}{0 - ( - 1)}$

$\dfrac{3}{ 1}$

now, let's plug the value of slope (m)

and y - intercept (c) in general equation

of line in slope intercept form.

i.e y = mx + c

so, we get the equation of given line as :

y = 3x + 3
