Answer:
Step-by-step explanation:
1) Previous concepts
The binomial distribution is a "DISCRETE probability distribution that summarizes the probability that a value will take one of two independent values under a given set of parameters. The assumptions for the binomial distribution are that there is only one outcome for each trial, each trial has the same probability of success, and each trial is mutually exclusive, or independent of each other".
2) Solution to the problem
The probability in favor of the regulation based on the recent survey is:

Let X the random variable of interest "Number of favor respondents about the regulation", on this case we now that:
The probability mass function for the Binomial distribution is given as:
Where (nCx) means combinatory and it's given by this formula:
And we want to find this probability:
If we use X= "Number of respondednts opposed to the regulation we got the same answer", but on this case p = 1-0.68=0.32, and we want this probability:
Your domain is all positive numbers, and your range is all numbers. this is because no matter what you plug in for y, x will only ever get extremely close to 0, but never reach it or go below it, and if you put in large values of y x will get very big.
Answer:
3rd
Step-by-step explanation:
Answer:
403.75
Step-by-step explanation:
we can write the following equation
.75m+145=price
we just need to plug in 345 for m
.75*345+145=price
put this into a calculator and get 403.75
Answer:

Step-by-step explanation:
You are given the function
. To find the inverse function
do such steps:
1. Rewrite the function f(x) as

2. Express x in terms of y:

3. Change x into y and y into x:

Now, the inverse function is
