Answer:

Step-by-step explanation:
Given
Let
 Undergraduates
 Undergraduates
 Graduates
 Graduates
So, we have:
 -- Total students
 -- Total students
 --- students to select
 --- students to select
Required

From the question, we understand that 2 undergraduates are to be selected; This means that 2 graduates are to be selected.
First, we calculate the total possible selection (using combination)

So, we have:





Using a calculator, we have:

The number of ways of selecting 2 from 3 undergraduates is:




The number of ways of selecting 2 from 5 graduates is:




So, the probability is:




 
        
             
        
        
        
1199.3 (I'm assuming you mean round to the nearest tenth)
 
        
             
        
        
        
C is the answer because it is
        
             
        
        
        
Answer:
D. A over 4
Step-by-step explanation:
One quarter is equal to  . If her aunt is age 'a', than Salina's age is a/4
. If her aunt is age 'a', than Salina's age is a/4

The slope of the line passing the points (1, 1) and (0, 0) is 1
<h3>Slope of a line</h3>
The formula for calculating the slope of a line is expressed as
Slope = y2-y1/x2-x1
Given the coordinate points (1, 1) and (0, 0)
Substitute the given coordinate points
Slope = 0-1/0-1
Slope = -1/-1
Slope =1
Hence the slope of the line passing the points (1, 1) and (0, 0) is 1
