Answer:
The y-intercept of the function y=3x+2 is equal to the y-intercept of the function represented in the graph.
Step-by-step explanation:
The slope intercept form of a line.
.... (1)
Where, m is slope and b is y-intercept of the line.
The given function is
.... (2)
On comparing (1) and (2), we get
Therefore slope of given function is 3 and y-intercept of given function is 2.
From the given graph it is noticed that the line intersects the y-axis at y=2, therefore the y-intercept of the function represented in the graph is 2.
Therefore y-intercept of the function y=3x+2 is equal to the y-intercept of the function represented in the graph.

Answer:
0.0135 = 1.35% probability that, in a random sample of 4 visitors to the website, exactly 2 actually are looking for the website.
Step-by-step explanation:
For each visitor of the website, there are only two possible outcomes. Either they are looking for the website, or they are not. The probability of a customer being looking for the website is independent of other customers. This means that the binomial probability distribution is used 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.
5% of all visitors to the website are looking for other websites.
So 100 - 5 = 95% are looking for the website, which means that
Find the probability that, in a random sample of 4 visitors to the website, exactly 2 actually are looking for the website.
This is P(X = 2) when n = 4. So
0.0135 = 1.35% probability that, in a random sample of 4 visitors to the website, exactly 2 actually are looking for the website.
