The formula for distance between two points is:
In this case:
![x_{2} =0\\x_{1} =3\\y_{2} =-9\\y_{1} =-8](https://tex.z-dn.net/?f=x_%7B2%7D%20%3D0%5C%5Cx_%7B1%7D%20%3D3%5C%5Cy_%7B2%7D%20%3D-9%5C%5Cy_%7B1%7D%20%3D-8)
^^^Plug these numbers into the formula for distance like so...
![\sqrt{(0-3)^{2} + (-9 - (-8))^{2}}](https://tex.z-dn.net/?f=%5Csqrt%7B%280-3%29%5E%7B2%7D%20%2B%20%28-9%20-%20%28-8%29%29%5E%7B2%7D%7D)
To solve this you must use the rules of PEMDAS (Parentheses, Exponent, Multiplication, Division, Addition, Subtraction)
First we have parentheses. Remember that when solving you must go from left to right
0 - 3 = -3
-9 - (-8) = -1
![\sqrt{(-3)^{2} + (-1)^{2}}](https://tex.z-dn.net/?f=%5Csqrt%7B%28-3%29%5E%7B2%7D%20%2B%20%28-1%29%5E%7B2%7D%7D)
Next solve the exponent. Again, you must do this from left to right
(-3)² = 9
(-1)² = 1
![\sqrt{(9+1)}](https://tex.z-dn.net/?f=%5Csqrt%7B%289%2B1%29%7D)
Now for the addition
9 + 1 = 10
√10 <<<This can not be further simplified so this is your exact answer
Your approximate answer would be about 3.16
***Remember that the above answers are in terms of units

Answer:
in the picture
Step-by-step explanation:
if u get some wrong i am so so sorry about it
The correlation coefficient (r) of the height and weight is 0.40391008.
Rounded, It will be 0.4
That means that the correlation between the height and weight is a positive weak correlation.
Answer:
50 times
Step-by-step explanation:
150 divided by 3 is 50
Answer:
(-3, -2)
Step-by-step explanation:
When a point is translated, the key words are very important to look at.
Up/down means you are translating the y axis.
Left/right means you are translating the x axis.
So using this key, we can solve.
-------------------------------------------------------------------------------------------------------------
A point located at (-3, 2) is translated down 4 units.
Since the point is going down, we will be translating the y axis. 2-4 is -2.
Since the x is staying the same, the x will be -3.
So your translated points are (-3, -2)
