Answer:

8x +4y

Step-by-step explanation:

6x + 3y + 2x + y

1) add similar variables together.

2) 6x + 2x = 8x

    3y + (1)y = 4y.

3) y by itself basically means 1y, since in front of every variable theres an invisible 1.

Internet Pricing An Internet Service Provider (ISP) offers its customers three options:
Mama L [17]

Answer:

(b)$29.62

(c)$5.73

Step-by-step explanation:

Basic: Standard internet for everyday needs, at $24.95 per month.

Premium: Fast internet speeds for streaming video and downloading music, at $30.95 per month.

Ultra: Super-fast internet speeds for online gaming at $40.95 per month.

Let the number of customers on Ultra=x; therefore:

Number of Premium customers =2x

Number of Basic customers =3x

Total=x+2x+3x=6x

P(Ultra)=\dfrac{x}{6x}=\dfrac{1}{6}  \\P(Premium)=\dfrac{2x}{6x}=\dfrac{1}{3}\\P(Basic)=\dfrac{3x}{6x}=\dfrac{1}{2}

(a)X=Monthly fee paid by a randomly selected customer.

Therefore, the probability distribution of X is given as:

\left|\begin{array}{c|c}X&P(X)\\---&---\\\$24.95&3/6\\\$30.95&2/6\\\$40.95&1/6\end{array}\right|

(b)Average Monthly Revenue per customer

Mean,

\mu=(\$24.95 \times 3/6)+(\$30.95 \times 2/6)+(\$40.95 \times 1/6)\\=\$29.62

(c)Standard Deviation

\left|\begin{array}{c|c|c|c|c}x&P(x)&x-\mu &(x-\mu)^2&(x-\mu)^2P(x)\\-----&-----&----&----&-----\\\$24.95&3/6&-4.67&21.8089&10.9045\\\$30.95&2/6&1.33&1.7689&0.5896\\\$40.95&1/6&11.33&128.3689&21.3948\\-----&-----&----&----&-----\\&&&&32.8889\end{array}\right|

\text{Standard Deviation}=\sqrt{(x-\mu)^2P(x)}\\=\sqrt{32.8889} \\ \sigma=\$5.73

Hello can someone please help me. I'll give 50 points.

No solutions

Set equations equal to each other
-3.5x - 3.5 = -3.5x + 3.5

The -3.5x on both sides of the equation cancels out, leaving

-3.5 = 3.5

But -3.5 does NOT equal 3.5, so the solution to the system of equations is false. This means that there are no solutions.
