Answer:

8 = f (13-2)

8=13f-2f

8=11f

8 / 11 = 11f / 11

8/11=f

f=8/11

Answer:

Simplifying

8 = F + -1(13 + -2)

Combine like terms: 13 + -2 = 11

8 = F + -1(11)

Multiply -1 * 11

8 = F + -11

Reorder the terms:

8 = -11 + F

Solving

8 = -11 + F

Solving for variable 'F'.

Move all terms containing F to the left, all other terms to the right.

Add '-1F' to each side of the equation.

8 + -1F = -11 + F + -1F

Combine like terms: F + -1F = 0

8 + -1F = -11 + 0

8 + -1F = -11

Add '-8' to each side of the equation.

8 + -8 + -1F = -11 + -8

Combine like terms: 8 + -8 = 0

0 + -1F = -11 + -8

-1F = -11 + -8

Combine like terms: -11 + -8 = -19

-1F = -19

Divide each side by '-1'.

F = 19

Simplifying

F = 19

You roll 4 fair, distinguishable, six-sided dice. What is the probability of rolling :______

Vikentia [17]

Answer:

a)0.25

b)0.375

Step-by-step explanation:

Possible outcomes when dice are rolled : 1 ,2 ,3,4,5 ,6

Even= 2,4,6

Odd = 1 ,3 , 5

Probability of getting even = $\frac{3}{6}=\frac{1}{2}$

Probability of getting odd = $\frac{3}{6}=\frac{1}{2}$

4 dices are rolled together

a)P(3 even and 1 odd numbers)

P(3 even and 1 odd numbers)= $^4C_3 (\frac{1}{2})^3 (\frac{1}{2})^1$

P(3 even and 1 odd numbers)= $\frac{4!}{3!1!} (\frac{1}{2})^3 (\frac{1}{2})^1 =0.25$

b)P(2 even and 2 odd numbers)

P(2 even and 2 odd numbers)= $^4C_2 (\frac{1}{2})^2 (\frac{1}{2})^2$

P(3 even and 1 odd numbers)= $\frac{4!}{2!2!} (\frac{1}{2})^2 (\frac{1}{2})^2$ =0.375

Using the completing-the-square method, rewrite f(x) = x2 - 6x + 2 in vertex form.<br>

sp2606 [1]

Answer:

$\large\boxed{f(x)+(x-3)^2-7}$

Step-by-step explanation:

$\text{The vertex form of equation}\ y=ax^2+bx+c:\\\\y=a(x-h)^2+k\\\\\text{We have the equation:}\\\\f(x)=x^2-6x+2=x^2-2(x)(3)+1=x^2-2(x)(3)+3^2-3^2+2\\\\\text{Use}\ (a-b)^2=a^2-2ab+b^2\to x^2-2(x)(3)+3^2=(x-3)^2\\\\f(x)=(x-3)^2-9+2=(x-3)^2-7$
