Answer:80students
Step-by-step explanation:
Using set notation concept,
n(U) be the total number of student = 200
n(AnS') be those that earned Bachelor in Art only= 120
n(A'nS) be those that earned Bachelor in Science only= 40
n(AnS) be students that earned both degrees.
Using the formulae below to calculate n(AnS) first;
n(AuS)=n(A'nS)+ n(AnS)+n(AnS')
200=40+n(AnS)+120
200=160+n(AnS)
n(AnS)=40
This shows that 40students earned bachelor in both degrees
Those that earned Bachelor in science degree will then be n(A'nS)+n(AnS) i.e 40+40 =80students.
NB: A' means complement of A(A not included)
'n' denote intersection and 'u' denote union.
The answer is 523.6 and all you have to do is round it to the nearest hundredth
The mean and standard deviation of the x sampling distribution for each of the following sample sizes will be 
.
<h3>What is the distribution of the sample mean for large samples?</h3>
Suppose X has a distribution with mean 
and standard deviation 
then,
the distribution of the mean of samples of size n, drawn from the values of X, is normally distributed with a mean equal to the mean of X, and a standard deviation equal to 
Symbolically, we write it as:
A random sample is selected from a population with a mean = of 100 and a standard deviation = of 10.

Answer:
y = 4x - 1
Step-by-step explanation:
The slope of the line (m) is 4. The line crosses the y-axis at a y-value of -1, so b = -1.
Answer:
start by getting 3% of 134000 and adding that on which gives us 138020 for the year 2005. get 3% of 138020 and add that on for the population in 2006 etc. in 2020 the population would be 215,031
