Answer:
Step-by-step explanation:
We have that:
In which P(a) is the probability of a but not b and 
is the probability of both A and B.
By the same logic, we have that:
Also
P(A or B) is
Events A and B are mutually exclusive
This means that 
Answer:
88 x 0.26 = 22.88% or 23%
Let's do the math, 2.5+2.5+2.5+2.5( 4times) is 10hrs+2.5= 12.5hrs
Answer:

Answer:
B) f(x) = 3x² - 2x + 5
Step-by-step explanation:
To find the correct quadratic function that represents the table, you must substitute [x] into the quadratic function.
A) f(x) = 3x² + 2x - 5
B) f(x) = 3x² - 2x + 5
C) f(x) = 2x² + 3x - 5
D) f(x) = 2x² - 2x + 5
A. 3(-2)² + 2(-2) - 5 =
3(4) - 4 - 5
12 - 4 - 5
12 - 9
= 3
B. 3(-2)² - 2(-2) + 5 =
3(4) + 4 + 5
12 + 9
= 21
C. 2(-2)² + 3(-2) -5 =
2(4) - 6 - 5
8 - 11
= - 3
D. 2(-2)² + 2(-2) + 5 =
2(4) - 4 + 5
8 - 4 + 5
8 + 1
= 9
Your correct answer is: B
