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.

Could someone pls help me out ???
professor190 [17]

Answer:

Option C.

Step-by-step explanation:

\sf\:x^{2}-3x+7=0

Use the biquadratic formula.

\sf\:\x=\frac{-\left(-3\right)(+/-)\sqrt{\left(-3\right)^{2}-4\times 7}}{2}

\sf\:x=\frac{-\left(-3\right)(+/-)\sqrt{9-4\times 7}}{2}

\sf\:x=\frac{-\left(-3\right)(+/-)\sqrt{9-28}}{2}

\sf\:x=\frac{-\left(-3\right)(+/-)\sqrt{-19}}{2}

\sf\:x=\frac{3(+/-)\sqrt{19}}{2}

Positive sign:

\boxed{\sf\:x=\frac{3+\sqrt{19}}{2}}

Negative sign:

\boxed{\sf\:x=\frac{3-\sqrt{19}}{2}}

Hope it helps ⚜

ine segment XY has endpoints X(–10, –1) and Y(5, 15). To find the y-coordinate of the point that divides the directed line segme
stiks02 [169]
X=(-10,-1)=(Xx,Yx)→Xx=-10, Yx=-1
Y=(5,15)=(Xy,Yy)→Xy=5,Yy=15
y=?
ratio=5:3→r=5/3
y=(Yx+rYy) / (1+r)
y=[-1+(5/3)15] / (1+5/3)
y=[-1+(5*15)/3] / [(3+5)/3]
y=(-1+75/3) / (8/3)
y=(-1+25) / (8/3)
y=(24) / (8/3)
y=24*(3/8)
y=72/8
y=9

Asnwer: T<span>he y-coordinate of the point that divides the directed line segment XY in a 5:3 ratio is y=9</span>

How many solutions does the equation have?<br><br> 4(z−5)+2=4z−18
ANTONII [103]
Distribute the 4:
4z - 20 + 2 = 4z - 18
Subtract 4z
-20 + 2 = -18
-18 = -18
This is true so that means there are infinite number of solutions... z could be anything!
