The answer would be 12 triangles. hope that helped
Answer:
Option B.
Step-by-step explanation:
In a regression of y in x, the proportion oh the variation in y explained by the variable x is shown in the R-squared value. So, for answering this question we need to look at the R-squared of such regression.
In this case the R-squared is 98.9% (or 0.989), so we will the option that matches this value. Looking at your options, the one that matches the R-squared is option B.
So, B is the correct option.
Answer:
∠ p ≈ 59°
Step-by-step explanation:
Using Pythagoras' identity in right triangle ABD to find DB
DB² = 5² + 6² = 25 + 36 = 61 ( take square root of both sides )
DB = 
---------------------------------------
Using the cosine ratio in right triangle DBC
cos p = 
= 
= 
, thus
p = 
( ) ≈ 59°
Answer:
yes
Step-by-step explanation:
-1 1/2 = -3/2
A rational number is a number that can be written as a fraction of integers.
-1 1/2 is the same as -3/2.
-3 and 2 are integers, so -3/2 is a fraction of integers.
