A bag contains 11 red chips and 12 blue chips. Two chips are selected randomly without replacement from the bag. What is the pro
Elena-2011 [213]

Answer:

11/23 or 0.478

Step-by-step explanation:

1. Find the probability of selecting 2 red chips:

11/23 * 10/22 = 5/23

2. Find the probability of selecting 2 blue chips:

12/23 * 11/22 = 6/23

3. Add the two probabilities:

5/23 + 6/23 = 11/23 = 0.478 (rounded to 3 decimal places)

HELP WITH ALL <br> Determine the composite functions of the following set of functions
elixir [45]

QUESTION 1

i) Given f(x)=5x-2 and g(x)=x^2.

(f\circ g)=f(g(x))

(f\circ g)=f(x^2)

We plug in x^2 into f(x)=5x-2

(f\circ g)=5x^2-2

ii) Given f(x)=5x-2 and g(x)=x^2.

(g\circ f)=g(f(x))

(g\circ f)=g(5x-2)

We plug in 5x-2 into g(x)=x^2

(g\circ f)=(5x-2)^2

(g\circ f)=25x^2-10x-10x+4

(g\circ f)=25x^2-20x+4

QUESTION 2

i) Given g(x)=x^2-4 and h(x)=\sqrt{2x+1}.

(h\circ g)=h(g(x))

(h\circ g)=h(x^2-4)

We plug in x^2-4 into h(x)=\sqrt{2x+1}

(h\circ g)=\sqrt{2(x^2-4)+1}

(h\circ g)=\sqrt{2x^2-8+1}

(h\circ g)=\sqrt{2x^2-7}

ii) Given g(x)=x^2-4 and h(x)=\sqrt{2x+1}.

(g\circ h)=g(h(x))

(g\circ h)=g(\sqrt{2x+1})

We plug in \sqrt{2x+1 into g(x)=x^2-4

(g\circ h)=(\sqrt{2x+1})^2-4

(g\circ h)=2x+1-4

(g\circ h)=2x-3

QUESTION 3

i) Given g(x)=x+5 and h(x)=\sqrt{x-4}.

(g\circ h)=g(h(x))

(g\circ h)=g(\sqrt{x-4})

We plug in \sqrt{x-4} into g(x)=x+5

(g\circ h)=\sqrt{(x-4)+5}

ii) Given g(x)=x+5 and h(x)=\sqrt{x-4}.

(g\circ g)=g(g(x))

(g\circ g)=g(x+5)

We plug in x+5 into g(x)=x+5

(g\circ g)=(x+5)+5}

(g\circ g)=x+10}

QUESTION 4

The given functions are;

f(x)=-2x+1 and g(x)=-x^2  

f\circ f=f(f(x))

f\circ f=f(-2x+1)

f\circ f=-2(-2x+1)+1)

f\circ f=4x-2+1)

f\circ f=4x-1)

ii)  

g\circ g=g(g(x))

g\circ g=g(-x^2)

g\circ g=-(x^2)^2

g\circ g=-x^4

QUESTION 5

f(x)=5x-2;g(x)=x^2;h(x)=-3x

h\circ g\circ f=h\circ (g(f(x))

h\circ g\circ f=h\circ (g(5x-2))

h\circ g\circ f=h\circ ((5x-2)^2)

h\circ g\circ f=h\circ (25x^2-20x+4)

h\circ g\circ f=h(25x^2-20x+4)

h\circ g\circ f=-3(25x^2-20x+4)

h\circ g\circ f=-75x^2+60x-12)

ii.

f\circ f\circ g=f\circ (f(g(x))

f\circ f\circ g=f\circ (f(x^2)

f\circ f\circ g=f\circ (5x^2-2)

f\circ f\circ g=f(5x^2-2)

f\circ f\circ g=5(5x^2-2)-2

f\circ f\circ g=25x^2-10-2

f\circ f\circ g=25x^2-12

Find AM in the parallelogram if PN =15 and AO = 6. The diagram is not to scale.
valentinak56 [21]

Answer:

6

Step-by-step explanation:

The diagonals of a parallelogram bisect each other.

The diagonals are PN and MO. The point A divides PN into 2 equal segments as well as MO into 2 equal segments.

Since AO = 6, MA should also be equal. Hence, MA (or AM) = 6.

The correct answer is AM = 6

Part 3: Find the inverse function, f –1(x), for the function f (x) = x2 + 10x + 28.
jasenka [17]

Answer:

-5+(√x-3) and -(√x-3)-5

Step-by-step explanation:

change f(x) to 'y' and then interchange x and y; then solve for y

y = x² + 10x + 28

x = y² + 10y + 28

you can use the Quadratic Formula to evaluate y² + 10y + 28 and will get:

-5+(√x-3) and -(√x-3)-5
