Sophia
Part B
What is the correct answer for 1.25 + 0.4?
1.65
The linear equation:
y = k x + b
We will use first two values and solve the system of equations:
11 = k * 7 + b / *(-1)
13 = k * 8 + b
---------------------
-11 = - k * 7 - b
13 = k * 8 + b
----------------------
2 = k
13 = 16 + b
b = 13 - 16 = -3
y = 2 x - 3 ( y varies directly with x )
Answer:
Step-by-step explanation:
"mutually exclusive" means "cannot happen at the same time." There's no "union" (no A ∩ B). The probability of this "union" is zero.
