**Answer:**

Hey there!

Density = Mass/Volume

Mass= 6g

Volume=24 mL, which is 24 cm^3

Density= 6g/24 cm^3

**Density=0.25 g/cm^3**

Let me know if this helps :)

True because the plates shift underground on the continental plate boundaries forming an earthquake

**Answer:**

B and D

**Step-by-step explanation:**

First off, we can rotate it. When rotating, I found that the x and y values switch places in a way.

We would need to rotate it 90 degrees counterclockwise about the origin in order to get it in the same position as triangle BDE. This makes statement B correct.

In order to make triangle ABC smaller, the dilation would have to be smaller than one. Counting the right side's length, ABC has 6 squares and BDE has 3.

This would mean 6 * 1/2 = 3, meaning statement D is true.

P2 = 71/411 = 0.1727

p1 = 64/253 = 0.2530

(p1 - p2) = 0.2530 - 0.1727 = 0.0803

SE = sqrt{[p1(1 - p1)/n1] + [p2(1 - p2)/n2]} = sqrt{[0.2530(1 - 0.2530)/253] + [0.1727(1 - 0.1727)/411]} = sqrt(0.000747 + 0.0003476) = sqrt(0.001095) = 0.0331

females at this university who would respond less than one week =</span> (p1 - p2) + or - 1.96(SE) = 0.0803 + or - 1.96(0.0331) = 0.0803 - 0.0648 to 0.0803 + 0.0648 = 0.0155 to 0.1451

b.) Yes.

**Answer:**

9 inches

**Step-by-step explanation:**

The population is within 6 standard deviations of the mean with a confidence of 99.7 percent, 3 above and 3 below

The standard deviation of the sample mean is equal to the population standard deviation divided by the square root of the sample size

population standard deviation = 36

sample size = 144

standard deviation of the sample mean = 36/ sqrt(144)

=36/12

=3

The margin of error is the number of standard deviations above the mean * the standard deviations

margin of error = 3 * 3

= 9 inches
