Answer:

No, the two figures are oriented differently.

Step-by-step explanation:

It's actually a reflection and then a translation! The thing is that the figure is reflected over the y-axis and then translated, and we know this because the points have switched places and the shape moved up! :)

Suppose the number of residents within five miles of each of your stores is asymmetrically distributed with a mean of 25 thousan

ohaa [14]

Answer:

$P(\bar X\:>27.8\:thousand)=3.07\%$

Step-by-step explanation:

Since the number of residents within five miles of each of your stores is asymmetrically distributed, the distribution of the sample means will be approximately normal with a mean of 25 thousand.

The standard deviation of the sample means is:

$\sigma_X=\frac{\sigma}{\sqrt{n} }$

$\implies \sigma_X=\frac{10.6}{\sqrt{50} }=1.4991$

The z value is $z=\frac{\bar X-\mu}{\frac{\sigma}{\sqrt{n}} }$

We plug in the values to get:

$z=\frac{27.8-25}{1.4991}=\frac{2.8}{1.4991}=1.87$

The area to the right of 1.87 is $1-0.96926=0.03074$ .

The probability that the average number of residents within five miles of each store in a sample of 50 stores will be more than 27.8 thousand is 3.07%

-5x-14=6y written in standard form

elixir [45]

Answer:

5x + 6y = -14

Step-by-step explanation:

Standard form means the x term will be on the farthest left, then the y term next, set equal to the constant (plain number) all by itself on the right.

Like this:

Ax + By = C

So you have

-5x - 14 = 6y

Add 14 to both sides.

-5x = 6y + 14

Subtract 6y from both sides.

-5x - 6y = 14

Also multiply both sides by -1, to make sure your A value (number next to the x) is positive.

5x + 6y = -14
