Answer:

\frac{1}{4}

Step-by-step explanation:

Since there are a total of 4 colors, and there are 5 of each colors, the total marbles in the bad would be;

5 x 4 = 20

If a color is selected at random the probability would be

\frac{part}{whole}

our part is 5

our whole is 20

so the probability would be;

\frac{5}{20} or \frac{1}{4} when reduced

Hope this helps!

Help with 8 and 9??? Please help me out! Correct answers please
Ipatiy [6.2K]

Answer:

  8.  (-∞, 0) ∪ (0, 1/3) ∪ (1/3, ∞)

  9.  f(g(x)) = 4x/(1+6x)

Step-by-step explanation:

8. For f(g(x)) to be defined, g(x) must be defined and f(g(x)) must be defined.

g(x) will be defined for all x≠0. f(g(x)) will be defined for g(x)≠4. Solving g(x)=4, we find the value of x is 1/3. (The answer choices give a clue.)

So, the domain of f(g(x)) is all x that is not 0 or 1/3. Only one answer choice makes those particular exclusions:

  (-∞, 0) ∪ (0, 1/3) ∪ (1/3, ∞)

__

9. Substituting the definition of g(x) into the expression for f(x), we get ...

\displaystyle (f\circ g)(x)=f(g(x))=\frac{2}{g(x)+3}=\frac{2}{\frac{1}{2x}+3}\\\\=\frac{2}{\left(\frac{1+6x}{2x}\right)}\\\\(f\circ g)(x)=\frac{4x}{1+6x}

3 sinx + 4 cosx = 5
vagabundo [1.1K]
<span>3sinx+4cosx=5
     => 3/5 sinx +4/5 cosx = 1
     let cosA=3/5   => sinA=4/5
     =>  cosAsinx + sinAcosx = 1
     =>  sin(x+A) = 1
Now,
       4sinx - 3cosx
  =   5(4/5sinx - 3/5 cosx)     [multipying numerator and denominator by 5]
  =   5(sinAsinx - cosAcosx)
  =   -5{cos(x+A)} = -5[root{1-(sin(x+A)^2)}] = -5 x 0 = 0          Ans 0
 
TRICK: if asinx+bcosx is given then multiply numerator and denominator by root(a^2 +b^2)
            this method is useful  in many questions </span>
