Answer:
Step-by-step explanation:
Number of drivers Screened = 671
Number Arrested for Driving While Intoxicating = 7
If the W denotes the event of screening a driver and getting someone who is intoxicated.
The Probability of W, 
- The Probability
is the probability of the event of screening a driver and getting someone who is not intoxicated. Simply put, it is the Probability of the Complement of W.
From Probability Theorem,
M = -2 and b = 3
so equation
y = -2x + 3

Answer:
250 days
Step-by-step explanation:
If the number of drops increases by a factor of 20/8, the expected life will decrease by the inverse of that factor: 8/20.
The expected life is (8/20)(625 days) = 250 days.
Answer:
64
Step-by-step explanation:
Note that each new term of this geometric sequence is 2x the previous term.
If the sequence starts off as 2, 4, 8, 16, 32 ... , then the next term is 2(32) = 64.

Answer:
a. 10x + 4; the answer is a polynomial
Step-by-step explanation:
The perimeter of a rectangle is the sum of the lengths of the 4 sides.
The closure property is that if you add polynomials, the sum is a polynomial.
A rectangle has two congruent lengths and two congruent widths.
Since the length of the rectangle is 3x + 5, there is another length of 3x + 5. The width is 2x - 3, so there is a second width of also 2x - 3.
Let's add the 4 sides together:
3x + 5 + 3x + 5 + 2x - 3 + 2x - 3 =
= 3x + 3x + 2x + 2x + 5 + 5 - 3 - 3
= 10x + 4
The perimeter is 10x + 4. Each side length is a polynomial, and the sum of the all the side length is also a polynomial. This shows there is closure for the addition of polynomials.
Answer: a. 10x + 4; the answer is a polynomial
