Answer:
The slope of the line= 2/3
Step-by-step explanation:
(2, 2)=(x, y) and (5, 4)=(`x, `y)
The formula for finding slope= `y-y/`x-x
4-2/5-2
2/3
Therefore, the slope=2/3
A. They are equal to each other.
Add up each number and you get 19.53 for both groups then when you divide by 9 ( the amount of individuals in each group) you get 2.17 for both groups so the mean is the same.
Answer:
D
Step-by-step explanation:
Changes made to your input should not affect the solution:
(1): "x1" was replaced by "x^1". 3 more similar replacement(s).
Step by step solution :
Step 1 :
Equation at the end of step 1 :
x + ((((3•19x2) • x6) • x8) • x12)
Step 2 :
Step 3 :
Pulling out like terms :
3.1 Pull out like factors :
57x28 + x = x • (57x27 + 1)
Trying to factor as a Sum of Cubes :
3.2 Factoring: 57x27 + 1
Theory : A sum of two perfect cubes, a3 + b3 can be factored into :
(a+b) • (a2-ab+b2)
Proof : (a+b) • (a2-ab+b2) =
a3-a2b+ab2+ba2-b2a+b3 =
a3+(a2b-ba2)+(ab2-b2a)+b3=
a3+0+0+b3=
a3+b3
Check : 57 is not a cube !!
Final result :
x • (57x27 + 1)
