Answer:

Fast Facts: Lipids

A lipid is any biological molecule that is soluble in nonpolar solvents.
Lipids include fats, waxes, fat-soluble vitamins, sterols, and glycerides.
Biological functions of lipids include energy storage, cell membrane structural components, and signaling

There are many different types of lipids. Examples of common lipids include butter, vegetable oil, cholesterol and other steroids, waxes, phospholipids, and fat-soluble vitamins. The common characteristic of all of these compounds is that they are essentially insoluble in water yet soluble in one or more organic solvents.

Determine the median value for foot width for males and for females. Describe in complete sentences the method you used to deter

Ipatiy [6.2K]

Answer:

This question is incomplete because of the absence of the data referred to in the question

Explanation:

This question is incomplete but the data referred to in the question is attached below

In order to determine the median value of any set of data, the data is first of all rearranged chronologically (ascending) and then the middle value is picked if the number of data is odd but if the number of data is even, the two middle values are added together and then divided by two to get the median.

From the data provided, the values (which are 10 in number) can be arranged as shown below (with the median values in bold)

Females: 5, 7, 7, 7.5, 7.5, 7.8, 7.8, 8, 8, 17

Males: 4.5, 7.5, 9, 9, 9.2, 9.3, 10, 10, 10.5, 13

Since the number of data is even, the two middle numbers (in bold) shall be added together and then divided to get the median as shown below

The median value for the females foot width is = 7.5 + 7.8/2 = 7.65 cm

The median value for the male foot width is = 9.2 + 9.3/2 = 9.25 cm

const2013 [10]

Answer:

(2) 988.5 mb.

Explanation:

The air pressure descends as we ascend. In other words, they are inversely proportional.

The air pressure descends as we ascend the mountain because the air molecules that are above us in high altitudes are fewer than the number of air molecules that are above us in the base of the mountain. So, the exerted pressure of the molecules on ourselves is lower in high altitudes.

Due to the reason mentioned above, we can deduce that the only correct option is option number two since the other ones show increasing or the same pressure, which is not possible as we ascend.
