Answer:

We have rocks from the Moon (brought back), meteorites, and rocks that we know came from Mars. We can then use radioactive age dating in order to date the ages of the surfaces (when the rocks first formed, i.e. when the lava cooled and crystallized). We also have meteorites from asteroids and can date them, too.

Find the mean, median, and mode of the following list of values. Round to the nearest tenth if necessary.

grin007 [14]

Answer:

D.

Mean: 24.8

Median: 26

Mode: 26

Explanation:

The mean is the average. To find the average, add up all the numbers and divide by the amount of numbers there are.

30 + 26 + 25 + 11 + 34 + 20 + 26 + 26 = 198

Now, we divide by how many numbers we started out with (8).

198 divided by 8 = 24.75, rounded would be 24.8

To find the median, you arrange the numbers from smallest to largest, and find the middle number like this:

11, 20, 25, 26, 26, 26, 30, 34

As you can see, the middle number is 26.

To find the mode, you arrange the number from smallest to largest, and find the number that appears more often.

11, 20, 25, 26, 26, 26, 30, 34

As you can see, the number 26 appears the most often.

So, we end up with:

Mean: 24.8

Median: 26

Mode: 26

Mrac [35]

The small, almond-shaped organs of the female reproductive system, suspended by ligaments in the upper lateral portion of the pelvic cavity are known as ovaries.

Ovaries are oval-shaped so are also termed almond-shaped organs and are present on the sides of the uterus in females. In females, the processes of pregnancy and ovulation which is also termed menstruation are controlled by the hormones that are made by ovaries. These hormones include estrogen and progesterone. Another major function of the ovary is that it releases the female gametes known as eggs during the menstrual cycle.

The ovaries are attached to two types of ligaments which are the ovarian ligament and suspensory ligament. Ovaries are connected to the womb by the ovarian ligament while the suspensory ligaments of the ovary contain the ovarian vessels and nerves.
