It is called the slope of the line
Answer:
Dependent Variable : Tire tread wear ; Independent Variable : Tire Brand ; Confounding Variable : Person driving
Step-by-step explanation:
Dependent Variable is the variable being affected by independent variable(s). Independent Variable(s) are the causal variable, bring change in dependent variable.
Goodrich wants to demonstrate that his tires were better than those of his competitor (Goodyear). For that, he has got conducted an independent research on tires worn quality - brand wise & various factors affecting wear
- Dependent Variable is the 'Tire tread wear '.
- Independent Variables determining it is primarily brand : Goodrich / Goodyear ; secondarily - price, mileage, time etc
Confounding variable is an extraneous influence variable; that changes the relationship between independent & dependent variable, outcome of experimental research.
In this case : Individuals driving the vehicles could be a confounding variable. A particular person could wear out tire more than another person.

Answer:
Part 9) 
Part 10) 
Step-by-step explanation:
we know that
The <u><em>Midpoint Theorem</em></u> states that: The segment joining two sides of a triangle at the midpoints of those sides is parallel to the third side and is half the length of the third side
Part 9) we know that
Point Q is the midpoint segment XY (QY=QX)
Point R is the midpoint segment XW (RW=RX)
Applying the Midpoint Theorem
RQ is parallel to WY
and
we have
substitute
solve for x
Part 10) we know that
Point B is the midpoint segment TS (BS=BT)
Point C is the midpoint segment RS (CS=CR)
Applying the Midpoint Theorem
BC is parallel to TR
and
we have
substitute
solve for x
Answer:
4 and 5
Step-by-step explanation:
Assuming your 2nd sentence should be: "The sum of the squares of the two numbers is 41"
X + Y = 9 {equation 1}
X² + Y² = 41 {equation 2}
from equation 1: y = 9-x
Substitute that into equation 2
x² + (9-x)² = 41
x² + 81 - 18x + x²= 41
2x² - 18x + 40 = 0
We can factor out a 2
x² - 9x + 20 = 0
(x-5)(x-4) = 0
x = 5 or 4
checking
Your two numbers are 4 and 5
4² + 5²
= 16 + 25
= 41
