That does look impossible someone plz help this man out or girl I don’t wanna assume genders ya know
Applying the distance formula, the distance from from Tia's home to Lei's home = 14.4 units.
<h3>What is the Distance Formula?</h3>
The distance formula helps us to find the distance between two given coordinate points. It is expressed as,
.
Tia = (4, 8) = (x1, y1)
Lei = (12, 20) = (x2, y2)
Apply the distance formula to find the distance from Tia's home to Lei's home:
d = √[(12−4)² + (20−8)²]
d = √[(8)² + (12)²]
d = √(64 + 144)
d = √208
d ≈ 14.4 units
The distance from from Tia's home to Lei's home = 14.4 units.

Answer:
A
Step-by-step explanation:
To write the equation, find the slope of the line using the two points. Find the difference in y values over the difference in x values.

Write the equation using the slope m=3/2 and the point slope form.

This is the equation of the line. You can convert it to slope intercept form:

Answer:
the correlation coefficient of the line of best fit is, 0.98247.
Step-by-step explanation:
Correlation Coefficient are used to find how strong relationship between the data. It expressed its values between +1 and -1. It is represented by r.
* if 0<r<1 indicates a strong positive relationship.
* -1<r <0 indicates a strong negative relationship.
* r=0 indicates no relationship at all.
The formula for this :
![r = \frac{n(\sum xy)-(\sum x)(\sum y)}{\sqrt{[n\sum x^2-(\sum x)^2][n\sum y^2-(\sum y)^2]}}](https://tex.z-dn.net/?f=r%20%3D%20%5Cfrac%7Bn%28%5Csum%20xy%29-%28%5Csum%20x%29%28%5Csum%20y%29%7D%7B%5Csqrt%7B%5Bn%5Csum%20x%5E2-%28%5Csum%20x%29%5E2%5D%5Bn%5Csum%20y%5E2-%28%5Csum%20y%29%5E2%5D%7D%7D)
Given the data: (-3, -40) , (1, 12), (5, 72) and (7,137)
Here, n = 4
To calculate the correlation coefficient r;
Substitute the values of data in above formla of r , as shown in the Figure 1:
then;
or
![r=\frac{5804-1810}{\sqrt{[336-100][102788 -32761]}}=\frac{3994}{\sqrt{[236][70027]}}](https://tex.z-dn.net/?f=r%3D%5Cfrac%7B5804-1810%7D%7B%5Csqrt%7B%5B336-100%5D%5B102788%20-32761%5D%7D%7D%3D%5Cfrac%7B3994%7D%7B%5Csqrt%7B%5B236%5D%5B70027%5D%7D%7D)
or

Therefore, the correlation coefficient r is, 0.98247 (Positive relationship)
