Answer:
18.75%
Step-by-step explanation:
Hello,
3 students are both female and senior
the total number of students is 7+10+8+5=30
so the probability to select one female senior is 3/30=1/10=0.10
probability to select one female is 16/30=16/30
probability that the student is a senior given that it's female is
=P(female and senior)/P(female)
=1/10*30/16=3/16
hope this helps
 
        
                    
             
        
        
        
The slope will be -1/2. If you put it into slope intercept form of y=mx+b, mx will always be the slope. 
        
                    
             
        
        
        
Answer:
   x = 2.5 or 7.5
Step-by-step explanation:
Subtract 3/4.
   |5 -x| = 10/4 = 2.5
This resolves to two equations:
- 5 -x = 2.5   ⇒   x = 5 -2.5 = 2.5
- 5 -x = -2.5   ⇒   x = 5 +2.5 = 7.5
The solutions are x = 2.5 or 7.5.

Answer:
Mean age = 1271.27
Step-by-step explanation:
No of children = 77
 The age at which children first began to combine words = 16.51 months
Mean age = No of children × age at which children first began to combine words
                 = 77 × 16.51
                  = 1271.27 
Mean age = 1271.27
