So we want to know how much Orlando owes, here's the answer:

Since he pays 121$ every month, the formula would be this:

y = 2,904 - 121x, if we consider x = months.

So the answer is B, y = 2,904 - 121x

Hope this helped! c:

Answer:

b. y=2904-121x

Step-by-step explanation:

Cost of the couch = $2904

Orlando will pay for 24 months = $121

The equation that Orlando can use to find out how much money he still owes after each month of the plan will be :

y=2904-121x

Let us check this :

Let us take x = 1

y=2904-121 = $2783 left to pay

Let us take x = 2

y=2904-121(2) = $2662 left to pay

Let us check x = 4

y=2904-121(4) = $2420 left to pay

Therefore, option B is correct.

The smallest square number which can be divisible by 11 and 5​
Elena L [17]

Answer:

3025

Step-by-step explanation:

let's look at it in this concept.

For a number to be divisible by 11 and 5. it must be a multiple of the LCM of 11 and 5.

LCM of 11 and 5=55

therefore the number is 55x, where x is a positive integer.

it is a said that the number is a perfect square

therefore the square root of 55x must be an integer.

\sqrt{55x}  =  \sqrt{5 \times 11 \times x}

the smallest value of x to make 55x a perfect square is....

x = 11 \times 5 = 55

Therefore the number is.... .

55x = 55(55) = 3025

Suppose the average price for new cars in 2012 has a mean of $30,100 and a standard deviation of $5,600. Based on this informati
KatRina [158]

Answer:

($13,300,$46,900)

Step-by-step explanation:

We are given the following in he question:

Mean, μ = $30,100

Standard Deviation, σ = $5,600

Chebyshev's Theorem:

  • According to  theorem atleast 1 - \dfrac{1}{k^2}  percent of data lies within 2 standard deviations of mean.
  • For k = 3,

1 -\dfrac{1}{(3)^2} = 0.889 \approx 89\%

Thus, 89% of data lies within three standard deviation of mean.

\mu - 3(\sigma) = 30100 - 3(5600) = 13300\\\mu + 3(\sigma) = 30100 + 3(5600) = 46900

Thus, we expect at least 89% of new car prices to fall within ($13,300,$46,900)

Determine the x-intercept for 3x + 2y = 14.
spin [16.1K]

First isolate y

3x + 2y = 14

-3x              -3x

2y = -3x + 14

y = -3/2x + 14/2

y = -3/2x + 7

X-intercept is found when y = 0

0 = -3/2x + 7

-7 = -3/2x

x = 14/3

x-in. = (14/3,0)
