Answer: 1 : 2 : 1

Explanation:

Carbohydrates were originally referred to as 'hydrates of carbon' because they contained hydrogen, oxygen and carbon.

Sugars, starches, cellulose, and gums all belong to the class of carbohydrates.

They are represented by the general formula Cx(H2O)y, where x and y must be whole numbers.

Thus, Carbohydrates contain carbon, hydrogen and oxygen in the ratio 1 : 2 : 1

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

How many different arrangement of four bases into triplets can be made
dsp73
4^3 = 64

There are 64 ways to arrange the four bases (Adenine, Thymine, Cytosine, and Guanine) into triplets (include repeats of bases as well, for e.g. AAT).

Just in case you are confused by my use of Thymine above, one thing to note is that Thymine will be replaced with Uracil in RNA.

Hope this helps! :)
