NATSSSSSSSSSSSSSS
The interpretation of the value of s being 0.67 is that: the typical distance between the observed grade points and predicted grade points was about 0.67 points.
The given parameters are:
<h3>Variable s</h3>
In regression, the variable s represents the average distance that the observed values fall from the regression line
<h3>The grade points</h3>
In this case, we have:
- The observed grade points and
- The predicted grade points
Hence, 0.67 represents the typical distance between the observed grade points and predicted grade points.

Answer:
(6 , 3)
Step-by-step explanation:
Given
x + 3y =15 ------- equation 1
4x + 2y = 30 --------- equation 2
x = 15 - 3y
Put value of x in equation 2
4 (15 - 3y) + 2y = 30
60 - 12y + 2y = 30
-10y = -30
divide by '-10' on both sides
y = 3
now, put value of y in equation 1
x + 3(3) = 15
x + 9 = 15
x = 15 - 9
x = 6
So , (x , y) = (6 , 3)
Answer:
x = 39
Step-by-step explanation:
all triangles have angle measures that add up to 180°.
This means that to find what x is, you add 102 and 39, and then subtract that from 180, so
180-(102+39) = x
180-141=x
39=x
4 plus negative 3 is 1.
When adding negative numbers to positive ones, you should treat it as a normal subtraction, so 4-3.
