The ratio of two numbers is $2:3$. when 6 is subtracted from the smaller of the two numbers and 7 is added to the larger of the

patriot [66]

Answer:

Step-by-step explanation:

Let the smaller and larger numbers be represented by S and L, respectively.

S/L = 2/3 . . . . the original ratio of the numbers

3S = 2L . . . . . multiply by 3L

(S-6)/(L+7) = 2/7 . . . . the new ratio of the numbers

7(S-6) = 2(L+7) . . . . . multiply by 7(L+7)

7S -42 = 2L +14

Using the expression for 2L from the first ratio, we can substitute to get ...

7S -42 = 3S +14 . . . . substitute 3S for 2L

4S = 56 . . . . . . . . . . .add 42-3S

S = 14 . . . . . . . . . . . . . divide by 4

The original smaller number was 14.

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

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

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

2. At one time, the ratio of in-state to

NISA [10]

Answer:

The out-of-state tuition would be $8800.

Step-by-step explanation:

Given that:

The ratio of in-state tuition to out-state tuition = 3:11

If the tuition of in-state is $2400.

Let,

x represent the number of out-of-state tuition.

As the relation is directly proportional.

3 : 11 :: 2400 : x

Product of mean = Product of extreme

11*2400 = 3x

3x = 26400

Dividing both sides by 3

$\frac{3x}{3}=\frac{26400}{3}\\x=8800$

Hence,

The out-of-state tuition would be $8800.
