The equation is in slope intercept form, meaning y=mx+b.
m is the slope. in your equation, -9 is in the m slot, meaning that -9 is the slope of that equation.

BRO PLEASE HELP ME IM BEGGING YOU Find the perimeter. Simplify your answer

Ostrovityanka [42]

Answer:

22s - 9

Step-by-step explanation:

The perimeter (P) is the sum of the 4 sides , that is

P = 2s + 7 + 9s - 5 + 6s - 10 + 5s - 1 ( collect like terms )

= (2s + 9s + 6s + 5s) + (7 - 5 - 10 - 1)

= 22s + (- 9)

= 22s - 9

Romashka [77]

Answer:

x < 2

Step-by-step explanation:

5(2x + 8) < 60 ( divide both sides by 5 )

2x + 8 < 12 ( subtract 8 from both sides )

2x < 4 ( divide both sides by 2 )

x < 2

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.
