Answer:
y>=1*x+2
Step-by-step explanation:
y>=k*x+n
we know that 2=k+n and 0=-2k+n
so 4=2k+n and 0=-2k+n
now 4=2n so n=2
now k=1
so y>=1*x+2
Answer:
13
Step-by-step explanation:
4/87 is around 0.046
13+0.046=13.046
13.046 to the nearest half is 13
Answer:





Step-by-step explanation:
For each homeowner, there are only two possible outcomes. Either they have invested in earthquake insurance, or they have not. The probability of a home owner having invested in earthquake insurance is independent from other homeowners. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

In which
is the number of different combinations of x objects from a set of n elements, given by the following formula.

And p is the probability of X happening.
32% of all homeowners are insured against earthquake damage.
This means that 
Four homeowners are to be selected at random.
This means that 
Find the probability distribution of X.
This is the probability of each outcome
