B
Step-by-step explanation:
Class A mean: 4.8
Class B mean: 4
B) yes, .8 less
Just find the y intercept which is 7m.
Answer:
20
Step-by-step explanation:
We know that the formula for the area of something is 1/2 * base * height
So we multiply 1/2 * 8 * 2 for The first triangle and get 8
Repeat for the other 3:
1/2* 2*2 = 2
8+8+2+2 = 20
* there are 4 triangles but I only needed to do the formula for two of them because they have identical triangles.
I hope this helps :)

Answer:
y = 
Step-by-step explanation:
Given
- 3y = - 
Multiply both sides by 5 to eliminate the fraction
- 15y = - 6 ( divide both sides by - 15 )
y =
=
= 
This is the concept of algebra, given a polynomial with one variable like x and y, the degree is the largest exponent of the variable;
Given the expressions;
4x^3-2y^3+5y^2-5y The polynomial has a degree of 3 (both y and x have an exponent of 3)
3y3--xy=3y^3+xy The polynomial has a degree of 3 also (y has an exponent of 3)
