What is 2x+y=12 3x-18=y can you write it on paper

1 answer:

4 0

You have to.move the "2x" so then it'll be "y=12-2x" or "y=-2x+12" For the second one: 3x-18=y You'll move the "-18" so it'll be "3x=y-18 Then you'll move the "y" to where the "3x" is. So it'll be "-y+3x=18" Then move the "3x" "-y=-18-3x". Then you multiply the "-" to the WHOLE equation which will be "-(y=-18-3x) which will give you "y=3x+18". I hope that's what you were asking for.

suppose the nightly rate for a three star hotel in paris is thought to be bell-shaped and symmetrical with a mean of 160 euros a

Westkost [7]

Answer:

95.44%

Step-by-step explanation:

Mean rate (μ) = 160 euros

Standard deviation (σ) = 8 euros

For any given rate, X, the z-score is:

$z=\frac{X-\mu}{\sigma}$

For X = 144 euros:

$z=\frac{144-160}{8}\\ z=-2$

For X= 176 euros

$z=\frac{176-160}{8}\\ z=2$

In a standard distribution, a z-score of -2 corresponds to the 2.28th percentile, while a z-score of 2 corresponds to the 97.72th percentile.

Therefore, the percentage of hotels with rates between 144 and 176 euros is:

$P=97.72-2.28\\P=95.44\%$

Lori:

Answer:
A = $1,932.00

(I = A - P = $532.00)

Equation:
A = P(1 + rt)
