Answer:

Step-by-step explanation:
Given
-- total
--- defective
--- selected
Required
The probability of rejecting the batch
This means that at least one of the selected piece is defected.
So, we first calculate the probability that all the selected piece are accepted.
So, we have:

The denominator decreases by 1 because it is a probability without replacement; 180 is subtracted from the numerator to represent the number of non-defective CDs
So, we have:


Using the complement rule, the probability that the batch will be rejected is:

Answer: point form (2,3) and equation form is x=2 y=3
Step-by-step explanation:
would you like for me to explain it for you
Answer: Me don’t know
Step-by-step explanation:
(a)
Let's assume
y is total cost
x is number of ride tickets
(b)
Since, this is linear relationship
so, we can assume equation as

The Fall Festival charges $0.75 per ticket for the rides
so,

we can plug it

Kendall bought 18 tickets for rides and spent a total of $33.50 at the festival
so, we have
at x=18 , y=33.50
we can use it to find b

now, we can solve for b

we can plug it back
and we get

(c)
we got

here ,
y is the cost for anyone who only pays for festival admission and rides
x is number of admission
so, our equation will give total cost
