3x+15=18 we need to find x so what is x

Mathematics

Crank3 years ago
3 0
1. Put numbers that are on the same group.
3x = 18-15
(3 has x so it is separated from whole numbers 15 and 18)
(15 became negative because you moved it to the other side of the equals sign)

2. Simplify
3x = 18-15
3x = 3

3. Find x
Transfer 3 on 3x to the right side denominator (bottom)
That will make:
x = 3/3

4. Solve
3 divided by 3 is 1

ANSWER: x=1

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)
