An elementary school is offering 3 language classes: one in Spanish, one in French, and one in German. These classes are open to

Digiron [165]

Answer: The required probability is 0.674.

Step-by-step explanation:

Since we have given that

Number of students in the Spanish class = 38

Number of students in the French class = 27

Number of students in the German class = 16

Number of students in both spanish and French = 14

Number of students in both Spanish and German = 6

Number of students in both French and German = 5

Number of students in all three class = 2

So, it becomes:

$n(S\cup F\cup G)=n(S)+n(F)+n(G)-n(S\cap F)-n(G\cap F)-n(S\cap G)+n(S\cap F\cap G)\\\\n(S\cup F\cup G)=38+27+16-14-5-6+2=58$

So, Probability that he or she is taking at least one language class is given by

$\dfrac{58}{86}=0.674$

Hence, the required probability is 0.674.

If a point (-3/5,b) is on the graph of the equation 2x+3y=6 and also on the graph of y=x+3, what is the value of b?

Since the point satisfies the equation
  y = x +3
you have
  b = (-3/5) +3 = 12/5 . . . . . . . matches A. 12/5
