Find the solution to the equation:

Volgvan

Answer:

x = 1

Step-by-step explanation:

To find the solution to the equation given, we will follow the steps below:

2(3x-6)= -12+6

Open the bracket

6x - 12 = -12 + 6

6x - 12 =-6

Add 12 to both-side of the equation

6x -12 + 12 = -6 + 12

6x =6

Divide both-side of the equation by 6

6x/6 = 6/6

At the left-hand side of the equation, 6 will cancel-out 6 while at the right-hand side of the equation, 6 will be divided by 6

x = 1

The prices of three t-shirts styles are $24, $30 and $36. the probability of choosing a $24 t-shirt is 1/6. the probability of c

Slav-nsk [51]

$\text{Answer} : \text{The expected value of a t-shirt is \$31.}$

Explanation:

Since we have given that

The prices of three t-shirts styles i.e $24, $30, $36 with their probability is given by

$\frac{1}{6}, \frac{1}{2},\frac{1}{3}$

As we know that,

$E(X)= \sum_{1}^{3}x_iP(x_i)$

$\text{where} x_i \text{ is the prices of t- shirts styles}$

Now,

$x_1= \$24 , x_2=\$30 , x_3=$36$

and

$P(x_1)=\frac{1}{6},P(x_2)=\frac{1}{2}, P(x_3)=\frac{1}{3}$

So,

$E(X)= 24\times \frac{1}{6}+30\times\frac{1}{2}+36\times \frac{1}{3}\\=4+15+12\\=31$

So, the expected value of a t-shirt = $31.
