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.

Ebba is buying bulk fabric.

-Dominant- [34]

Answer:

To find the cost per yard, divide the cost by the amount:

p: 6.25 / 6.5 = 0.96 --> The cost per yard is $0.96

r: 3 /4 = 0.75 --> The cost per yard is $0.75

b: 8.1 /8.5 = 0.95 --> The cost per yard is $0.95

s: 7.2 / 6 = 1.2 --> The cost per yard is $1.20

In order from cheapest to most expensive:

Solve for the variable

krek1111 [17]

Answer:

G = 2/3

Step-by-step explanation:

-13G + 10 = 2(-5G + 4) Distribute the 2 to (-5G + 4)

-13G + 10 = -10G + 8

+13G +13G Add 13G to both sides

10 = 3G + 8

-8 -8 Subtract 8 from both sides

2 = 3G Divide both sides by 3

2/3 = G
