Answer: The equation is of line "b"
Step-by-step explanation:
First we find the slope of the given line by using slope intercept form.
Converting the equation into slope intercept form
Divide both side by 5 we get
On comparing with
We get slope
as the slope of line is negative therefore the line will be either line "b" or line "d"
As line "b" pass from (0,2)
On putting point in given equation we get
Which is equal to RHS of the line
Therefore the given equation is of line "b"
Now putting point (0,-2)
We get
Which is not equal to RHS and therefore line "d" is not the required line
Therefore the given equation is of line "b"

Answer:
Probability that exactly 5 of them have blue eyes is 0.1165.
Step-by-step explanation:
We are given that Researchers claim that 8% of people have blue eyes. Suppose the researchers' claim is true. Mrs. Greene has a Geometry class with 40 students.
The above situation can be represented through Binomial distribution;
where, n = number of trials (samples) taken = 40 students
r = number of success = exactly 5
p = probability of success which in our question is % of people
having blue eyes, i.e; 8%
<em>LET X = Number of students having blue eyes</em>
So, it means X ~
Now, Probability that exactly 5 of them have blue eyes is given by = P(X = 5)
P(X = 5) =
=
= 0.1165
Therefore, Probability that exactly 5 of them have blue eyes is 0.1165.
