A horizontal line is one for which the value of y is the same for the entire length of the line. Therefore this type of line can be expressed as below:
Where "c" is a constant that changes the position of the line on the coordinate plane. If c is equal to 2, then we have a constant line that crosses the y-axis at the position 2 for example.
Answer:
option a
Step-by-step explanation:
given that at a large Midwestern college, 4 % 4% of the students are Hispanic.
A random sample of 20 students from the college is selected.
We have each student is independent of the other to be hispanic
p = success = being hispanic = 0.04 while
q = failure = being non hispanic = 0.96
X - no of hispanics is thus binomial with p = 0.04 and n =20 (sample size)
Since X is binomial
Var(x) = npq = 0.768
Std dev (x) = Square root of variance =
rounded off it gives 0.88
So option a is right
