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)

Skylar makes turkey sandwiches for a family reunion. He purchases 5 pounds 4 ounces of sliced turkey for $26.88. What is the uni
Advocard [28]

Answer:

The unit cost per ounce for turkey skylar is $ 0.316  

Step-by-step explanation:

The total amount of sliced turkey = 5 pounds + 4 ounces

The total cost of turkey slice = $26.88

Now, as we know

1 pounds = 16 ounces

∴ 5 pounds = 16 × 5 = 80 ounces

So, the total amount is 5 pounds + 80 pounds = 85 pounds

∵ 85 pounds of turkey sliced cost $ 26.88

∴ 1 pounds of turkey sliced cost $ \frac{26.88}{85}  = $ 0.316

Hence the unit cost per ounce for turkey skylar is $ 0.316  Answer
