Answer:

B.

Step-by-step explanation:

Center is the point that does not change and that point is A. To find the scale factor you just divide the translated length by the original, in this case, 8÷2 which gives a scale factor of 4.

Answer:

The 95% confidence  interval is (150\pm 8.8).

Step-by-step explanation:

The information provided is:

\bar x=150\\\sigma = 20\\n=20

The critical value for 95% confidence level is:

z_{\alpha/2}=z_{0.05/2}=z_{0.025}=1.96

Compute the margin of error as follows:

MOE=z_{\alpha/2}\cdot\frac{\sigma}{\sqrt{n}}

          =1.96\times\frac{20}{\sqrt{20}}\\\\=1.96\times 4.47214\\\\=8.7653944\\\\\approx 8.8

Then the 95% confidence  interval is:

CI=\bar x\pm MOE

     =150\pm 8.8

Thus, the 95% confidence  interval is (150\pm 8.8).

50 POINTSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSS!!! HELP MEEEEEEEE

In geometry it is the shape made when a solid is cut through by a plane.

Example:

Part A: The name of the shape created by cross section of the prism is a square

<span>(We don't draw the rest of the object, just the</span><span> </span><span>shape</span><span> </span><span>made when you cut through.)</span>

<span>if Part B is a continuation from Part A then the shape of the resulting cross section would be a square.</span>

<span>if Part B is completely </span>separate<span> from Part A then the shape of the resulting cross section would be a rectangle.</span>

Since the wording is confusing I would, for part B, say that the shape of the resulting cross section is a rectangle regardless, because every square is always a rectangle but every rectangle is not always a square.

Part A- Square

Part B- Rectangle
