I believe that correlation without causation is the number of doctors

Correlation with causation is the number of high school seniors. Hope this helps!

Answer:

Correlation without Causation = The number of high school seniors and high school graduates.

Correlation with Causation = The amount of snowfall and the numbers of voters.

Step-by-step explanation:

Since there is a large relationship between the number of high school seniors and high school graduates but there is no cause of this relationship. So it has a Correlation without Causation.

Also, there is a large relationship between the amount of snowfall and the numbers of voters since more the snowfall occurs less will be voters gone for voting. Here is a cause of this relationship. So it has a Correlation with Causation.

and, there is not a good relationship between the number of doctors and the number of nurses.

Further, Correlation shows the strength of the relation between two variables and it does not mean that change in one variable is the cause of change in other variables.

And Causation is the occurrence of an event is the result of the occurrence of the second event.

Write an equation in slope-intercept form that goes through the points (-3, -4) and (3,4).

Marat540 [252]

Answer:

Y = 4/3x + 0

Step-by-step explanation:

(-3,-4) and (3,4) can be plugged in to rise over run.

y 4 -(-4) = 8

x 3 - (-3) = 6

8/6 = 4/3

Plug into slope intercept form

4 = 4/3(3) + b

4 = 12/3 +b

4 = 4 +b

Subtract from both sides

0 = b

Y = 4/3x + 0

Given f of x is equal to 1 over the quantity x minus 3 end quantity and g of x is equal to the square root of the quantity x plu

Lostsunrise [7]

The domain of the composite function is given as follows:

[–3, 6) ∪ (6, ∞)

<h3>What is the composite function of f(x) and g(x)?</h3>

The composite function of f(x) and g(x) is given as follows:

$(f \circ g)(x) = f(g(x))$

In this problem, the functions are:

$f(x) = \frac{1}{x - 3}$ .

$g(x) = \sqrt{x + 3}$

The composite function is of the given functions f(x) and g(x) is:

$f(g(x)) = f(\sqrt{x + 3}) = \frac{1}{\sqrt{x + 3} - 3}$

The square root has to be non-negative, hence the restriction relative to the square root is found as follows:

$x + 3 \geq 0$

$x \geq -3$

The denominator cannot be zero, hence the restriction relative to the denominator is found as follows:

$\sqrt{x + 3} - 3 \neq 0$

$\sqrt{x + 3} \neq 3$

$(\sqrt{x + 3})^2 \neq 3^2$

$x + 3 \neq 9$

$x \neq 6$

Hence, from the restrictions above, of functions f(x), g(x) and the composite function, the domain is:

[–3, 6) ∪ (6, ∞)

How many gallons of a 50% antifreeze solution must be mixed with 80 gallons of 30% antifreeze to get a mixture that is 40% a

Bas_tet [7]

I don't know what the "six-step method" is, but I do know how to solve the problem:

Let x = number of gallons of 50% solution

amount of antifreeze in 50% solution = 0.50x
amount of antifreeze in 10% solution = 0.10(80) = 8
amount of 40% solution = 0.40(x+80) = 0.40x + 32

Then, 0.50x + 8 = 0.40x + 32

0.10x = 24

x = 240 gal
