Answer:
A. 0.5
B. 0.32
C. 0.75
Step-by-step explanation:
There are 
- 28 students in the Spanish class, 
- 26 in the French class, 
- 16 in the German class, 
- 12 students that are in both Spanish and French, 
- 4 that are in both Spanish and German, 
- 6 that are in both French and German, 
- 2 students taking all 3 classes.
So, 
- 2 students taking all 3 classes, 
- 6 - 2 = 4 students are in French and German, bu are not in Spanish, 
- 4 - 2 = 2 students are in Spanish and German, but are not in French, 
- 12 - 2 = 10 students are in Spanish and French but are not in German, 
- 16 - 2 - 4 - 2 = 8 students are only in German, 
- 26 - 2 - 4 - 10 = 10 students are only in French, 
- 28 - 2 - 2 - 10 = 14 students are only in Spanish.
In total, there are 
2 + 4 + 2 + 10 + 8 + 10 +14 = 50 students. 
The classes are open to any of the 100 students in the school, so
100 - 50 = 50 students are not in any of the languages classes.
A. If a student is chosen randomly, the probability that he or she is not in any of the language classes is

B. If a student is chosen randomly,  the probability that he or she is taking exactly one language class is

C. If 2 students are chosen randomly,  the probability that both are not taking any language classes is

So,  the probability that at least 1 is taking a language class is

 
 
        
             
        
        
        
You did not provide us with equations to select.
Find the slope m.
m = (1 - 2)/(3 - (-1))
m = -1/(3 + 1)
m = -1/4
Use the slope and one of the points and plug into the point-slope formula. 
y - 1 = (-1/4)(x - 3)
Isolate y.
y - 1 = (-1/4)x + (3/4)
y = (-1/4)x + (3/4) + 1
y = (-1/4)x + (7/4)
Did you follow?
 
        
                    
             
        
        
        
Your answer would be A.) False; either both are right or one is obtuse
Two acute angles added could never equal 180
Hope this helps!
        
             
        
        
        
When it says 4x4 and 12x2 does that mean it’s squared or multiplied by those?
